Pink Sugar Frosting Body Lotion (Recipe)

Hello everybody! 😀

Today I am going to share with you a recipe for a body cream.

[If you are new to the making of lotions at home… you might want to run here! 😀
If you already know the basics but miss the ingredients you might want to read the post about where to buy cosmetic ingredients online (here!) 😀 ]

I made this cream for a good friend who just requested a good body cream for dry skin.
My intention was to get a very emollient cream (which often means “an important and well studied oily phase”) with few active ingredients to do good to the skin (we don’t want to use active ingredients only on our face: we can afford to use some also on the rest of our body 😉 ).

How I proceeded:
Picking the oils: being a body cream I wasn’t too concerned about using comedogenic oils or butters. This is why I used a 5% of Shea Butter (which, whatever you read online, is comedogenic due to its fatty acid composition… In case, you can read more about it here) without thinking twice. Shea butter is heaven for the skin of our body. As medium density oil I added Borage oil and Safflower oil, but the main part of my “Grease-Fall” was made of light and extra light oils (to be really honest Jojoba oil is a wax and the other two were synthetic oils which have the very good property of improving the feel of the cream on the skin. If you want to use only natural oils I will add options at the end of the post on how to change the recipe 😀 ).

Aloe Vera Hair Gel – Recipe

It is over a year now that my husband uses my Aloe Vera Hair Gel and he is very happy with it, but I never thought it would be interesting to post about it… until today 🙂

The recipe is really fool-proof-easy and it makes a good hair gel, which won’t become white if you brush through your hair after it dries up, the hairs stay in shape but don’t look glued!
It is also good if you have long hair and you want to give them proteins: use it in small amount on wet hair (just after you wash them) and then dry them as you are used to. In this case it doesn’t keep the shape but makes the hair shiny and in a month or two they look much more healthy and they feel stronger 🙂 (this is my experience).

There are three methods depending on your starting point:

Method 1: if you have Aloe Vera Juice you are going to use it instead of water (substitute the water of the recipe with the juice! 🙂 )

Method 2: if you have the concentrated Aloe Vera Powder (1:200) you will make the gel with glycerin, xanthan gum and water and then add the 0.5% Aloe Vera powder to your gel (it will melt immediately 😉 ).

Method 3: FOOL-PROOF! You can even use a bought Aloe Vera Gel (just make sure the Aloe Vera amount is at least around 95%! Run away from any “10% Aloe Vera Gel”) and add to it the other ingredients of this recipe (of course leaving out the xanthan gum, the glycerin and the water… easy no? :D). This method also works if you have your already homemade Aloe Vera Gel which you read in this post. In case the gel is too liquid, you can add a little bit of xanthan gum to have a more firm gel 😉

How to formulate a Face Wash – with Recipe

Now that we have studied the theory of Surfactants (here and here) and we have the values of some of them… it is time to finally formulate! 😀

The recipe of today is for a very delicate Face Wash which helped me when I used to suffer of a mild but annoying and constant (meaning that my skin wasn’t covered in pimples completely but I did have a few all the time and this lasted over two years) form of acne. I should make a post about this! I used to be quite aggressive with my skin: I was scrubbing, using alcoholic toners, applying aggressive creams… but nothing was helping (on the contrary…).
Then one day I decided to give a break to my skin, I stopped scrubbing crazily, I stopped attacking my skin and I started concentrating on eating more healthy food and… TADAAA it did the trick 😀 I simply found out that all my skin needed was to be treated gently.

This is how the formulation was done:

How to formulate a detergent – THEORY pt.2

Now we know the basics about our surfactants (if you haven’t read the previous post, go HERE) now it is time to actually formulate a detergent.

Even if you don’t plan on making the detergent by yourself, reading this might be useful to you in order to understand what’s actually inside your shampoo or other detergents and you will be able to understand if these products are delicate or not 😉

There are not totally wrong combinations of surfactants: you can mix them just by chance and eventually you will always get a detergent, whatever you do. What could go wrong is that you might get a very liquid detergent or you might get it more aggressive than you expected, but it will still be a detergent!
However there are some rules that, if followed, will give you a good detergent with a good density and the right washing-ability.

Controlling the DELICACY:
So far what we said is that mixing more surfactants will eventually give us a less harsh detergent (of course than a detergent made with a single surfactant keeping the active matter value stable).
We also said that when formulating, the best choice should be:
– an anionic or non-ionic surfactant; it is the surfactant which we will add in our detergent at higher %.
– an amphoteric surfactant; it will make the first surfactant more mild.
– extra surfactants: (usually non-ionic) these are used in very low percentage and are added to improve the lather or the consistency of the detergent.
Making this kind of combination of surfactants will give, as a result, a balanced detergent which will be delicate enough (this is of course also related to the active matter %).

Always as a matter of delicacy, if you add certain substances, they act as a protector to your skin (for example proteins, at 1-2%).
You could also think of superfatting your detergent and this low percentage of oil will “use” some of the surfactants making your detergent more mild on the skin. Notice, however, that some surfactants don’t “bear” the presence of oils (even an extra drop of perfume oil can disturb them) and get liquid immediately after you add them to the mixture (for example it is the case of sodium lauroyl sarcosinate).

VISCOSITY:
The viscosity of your product is very important: a water-like detergent gives to our subconscious the feeling that it cannot clean enough (even if it is not so).
The negative thing is that some surfactants, when combined, give a very liquid result.
Luckily there are few combinations of surfactants which work very well in giving you a dense detergent:
– SLES + betaine (an amphoteric surfactant) + salt = very dense detergent. Sodium chloride (salt) is often in commercial detergents, even in shampoos. However if you add too much it can make your detergent too harsh. In my shampoo I use SLES, cocamidopropyl betaine and I never needed to add salt because it was dense enough (sometimes even too much).
– SLS + a glucoside (this means a non-ionic surfactant: lauryl glucoside, decyl glucoside are the most common for example).
– sodium lauroyl sarcosinate + pH 5 (acidify your detergent to pH 5, using citric acid in a solution or lactic acid, and the sarcosinate will become thick)

There are also other things you can use in case your detergent is too liquid:
if you have already tried the recipe and you like the result as detergent but it is too liquid, the next time you repeat the recipe you can add xanthan gum to the water of the detergent in order to thicken it up a little bit. However do not use xanthan gum at more than 1% or the detergent will get an unpleasant slimy feeling.

There are also some synthetic thickeners exactly made for surfactants.
The best one so far is Tinovis GTC (Inci: Acrylates / Beheneth-25 Methacrylate Copolymer) because you can add it at the end of the making of your detergent and therefore you can adjust the density little by little.

Obviously if you don’t care how your detergent looks and you are fine with washing yourself with a water-liquid detergent… you can use it as it is! 🙂

Now finally to THE FORMULATION

Also the formulation of a detergent is divided in Phase A, B and usually C.

Phase A:
this will be our water phase and usually it contains water and glycerin (remember glycerin is important to keep our products hydrated, this is because glycerin is highly hydrophilic).
In case you want to add xanthan gum you have to add it now (also some synthetic thickeners have to be added in beginning so be sure to read the data sheet of your raw material in advance! 🙂 ).
You also add here any hydrophilic ingredient: for example you add your preservative (ONLY in case it is hydrophilic of course), your hydrophilic colorant (for example the food grade ones), and so on.

Phase B:
In our phase B we have most of the surfactants: usually we add the surfactant at higher percentage (which is usually an anionic surfactant) and one by one we add the “extra surfactants” which are usually the non-ionic ones.
IMPORTANT: do not add now the amphoteric surfactants (generally the betaine) or your detergent might get ruined (in the way it gets very liquid… once again: a detergent cannot really get spoiled and it will still clean your body even if you do something wrong).
Often I add the perfume and the lipophilic preservative directly here in the mixture of surfactants (of course in case I am not using already an hydrophilic one).
One important thing to notice is that once you add a surfactant to another you are supposed to mix slowly and combine them very well because you add a third one.

Now it is time to pour Phase A slowly into Phase B and mix.
This time we only use a spoon to mix, paying attention to not make too many bubbles (however even if you get too many bubbles, they will disappear with time).

Phase C:
This is the phase where you add the amphoteric surfactant and usually your detergent gets thick here.
If this doesn’t happen you can always add here your synthetic thickener (in case it is the kind that needs to be added in the end) or you can try by adding 1% salt or… once again… you can just use your detergent as it is and try to do better next time. 🙂
In case of shampoo you also are supposed to add at this moment all the hair conditioner substances (which will help your shampoo to not feel harsh on the hair)… but I will make a post specifically about hair shampoo to explain this better 😉

Next post will be a recipe for a detergent and I will also show you how to calculate the ACTIVE matter of your detergent, so stay tuned! 🙂
Have a great day! 😀

How to formulate a detergent – THEORY pt. 1

In this post I am going to talk about the formulation of detergents like face-wash, shampoo, shower gels, bubble bath and so on…

All these detergents are made starting from a family of ingredients: SURFACTANTS.
Surfactants are compounds that lower the surface tension of a liquid and therefore they emulsify the grease and the dirt on our skin and help us to wash it off with the aid of water.

Surfactants can be divided in four groups according to their ionic nature:
– cationic – positive charge when ionized. They are mostly used in conditioners.
– anionic – negative charge when ionized. They are largely used in detergents and shampoos and provide good detergency and lather. In this family we ding: SLS (sodium lauryl sulphate), SLES (sodium laureth sulphate), ammonium lauryl/laureth sulphate, sodium lauroyl sarcosinate, disodium laureth sulfoccinate.
– non-ionic – no charge (unionizable). They are lauryl glucoside, decyl glucoside, coco glucoside, caprylyl/capryl glucoside. These are usually not used in shampoos because they don’t leave a comfortable feeling on the hair (it makes them feel dry) unless they are included in the formulation in small amount (and therefore they work more as foam stabilizers).
– amphoteric – both positive and negative (depending on the pH). These are used a lot in shampoo formulation: specially if combined with SLES they help the shampoo to be thick and they also decrease the irritancy (read this in a relative way 🙂 ). They are for example: cocamidopropyl betaine, lauramidopropyl betaine, coco-betaine, cocamidopropyl oxide.

THE ACTIVE MATTER of a surfactant:
How “strong” do we need our detergent to be? This of course depends to what we aim to make: if we are going to make a bubble bath it will need to have a higher washing ability than a face-wash, which should, on the contrary, be very gentle and delicate. The washing ability of a detergent is determined by its “Active Matter” coefficient: every surfactant has an “active matter coefficient” which is a number in percentage (for example the SLES coefficient is 27%) and this tells us “how much active washing substance there is in our SLES… and in this case it is 27%”. This is because the liquid surfactants which we can easily find sold online are usually made of the real surfactant and water (so the active matter is not 100%). You should find out this number from where you purchase your surfactants (if they are not mentioned on the page, send an e-mail to the supplier).

Generally the active matter of surfactant we want in our detergent depending on its aim is this:
– Face wash – lower than 10%
– detergent for intimate use – around 5%
– shampoo – between 10% and 15%
– shower gel – between 18% and 20%
– bubble bath – between 20% and 25% (this is because the bubble bath should go directly in the water while the shower gel is supposed to be rubbed directly on the skin)

So now you might be thinking that to make a good shampoo you just need 45% SLES and rest of water and tadaaa… well… NO 😀
It is true that the 45% of SLES plus 55% water would give you a solution with 12.15% Active Matter (45*27(which is the active matter coefficient of SLES):100= 12.15) however there is something very important you still need to know:

In a formulation a single surfactant results more harsh than an equal “active matter %” formulation made with different surfactants.
To make it simple: if you mix surfactants together, you will have a milder results than using the surfactants alone.
A particularly happy mix is SLES with a betaine (usually I have cocamidopropyl betaine) because not only the betaine lowers the harshness of the SLES, but it also thickens the solution.

Generally when formulating you should use:
– anionic or non-ionic surfactant; it is the surfactant which we will add in our detergent at higher %.
– anphoteric surfactant; it will make the first surfactant more mild.
– extra surfactants: these are used in very low percentage and are added to improve the lather or the consistency of the detergent.

To be continued… 😉

DIY Vitamin C Serum

Vitamin C is a very powerful substance and it is found in many commercial products for the skin because it is a strong antioxidant, it has lightening properties and, last but not least, it boosts the production of collagen (therefore you are left with a firmer skin).

Vitamin C is “ascorbic acid” (you could also find “L-ascorbic acid”) but in the creams you buy, if you read the ingredients, you will never find “ascorbic acid”, probably you will find “sodium ascorbyl phosphate” or “magnesium ascorbyl phosphate” (there are also other forms of Vitamin C, this is a mere example). What is this?
Well, Vitamin C has great properties but it doesn’t keep stable: it oxidizes even in contact with air, with light… (this is why if you make fresh orange juice you should drink it immediately after), so in order to be able to add this vitamin in our face creams, cosmetologists use a stabilized form of Vit C: if in the ingredients of your cream you read an ingredient which contains the word “ascorbyl”, to make it very simple, that is the stabilized form of Vitamin C.

These stabilized forms are many and they are growing in number all the time. They are not something negative (and even I use them in the making of Vitamin C creams… maybe I will post a recipe soon about it 🙂 ), however their properties are not 100% the same of the pure Vitamin C.

Today I am going to show you the easiest and most effective way to make at home a special Vitamin C Serum which is much more powerful than every cream you ever bought 😀

The only way to use pure Vitamin C (therefore “L-ascorbic acid”) effectively is to use it right away and make a new serum all the time.
This is why the recipe of today, unlikely all the cream recipes I have shown before, is not in 100 gr but it is in very small amounts: because you will have to make it anew every time you want it 🙂
But don’t be scared: it is made of three ingredients only and it is divided in two parts 😉

RECIPE:
(first part)
1 teaspoon demineralized water
1/8 teaspoon L-ascorbic acid (you can easily buy it in pharmacy; ask for the powder of vitamin C or ask for Ascorbic acid, simply 😉 )
(if you wish to, you can add also a drop of glycerin)
You mix these two ingredients in a bowl and measure the pH (you can find pH strips even in pharmacy: buy those from 0 – 14 so you can use them also for the other homemade cosmetics in the future. They should look like THIS in order to show you exactly the correct pH of the solution).
WARNING! Measuring the pH is important!
Ascorbic acid is obviously an acid (and it is also very strong) so you don’t want to apply on your skin something of pH 2… however Vitamin C is well absorbed (and used) in your skin only at a pH range of 3.5 or lower. Therefore check the pH of the solution and if you see it is lower than pH 3.5 adjust the pH by adding a little bit more water. Now check the pH again and keep adjusting until the result is pH 3.5.
This is really important and I am not responsible if you ruin your skin.

At this point you can apply this water on your skin using a brush or even your own fingers, keep applying even in multiple layers until the water is finished.
WARNING! Do NOT apply on the eye area or too close to your lips or nostrils.
It is normal if it stings a little, but it should not be painful and it should not last more than 2 or 3 minutes.
WARNING! If you feel pain wash off immediately! If after 3 minutes the stinging hasn’t stopped yet, wash off immediately! Some people have a very delicate skin and this acid might be too strong for them. If this is your case, rinse off immediately and avoid using acids on your skin. They could damage it!

If instead your skin didn’t react badly to the Vitamin C boost :D, wait for the skin to be dry (wait approximately 10 minutes) and now it’s the part two 😉
(second part of the “recipe”)
2 drops of Vitamin E (Tocopheryl acetate or Tocopherol – you should be able to find it in pharmacy very easily. It is a very dense liquid. The Tocopheryl acetate should be transparent or slightly yellowish. Tocopherol, instead, is dark brown).
Put these two drops on the tips of your fingers and tap it all over your face.
This time it shouldn’t sting anymore.
Let it sit on your skin for 20 minutes and wash off (you will have to wash your face vigorously, because Vitamin E is quite sticky 😀 ).

This is the easiest, most effective Vitamin C serum.
After applying the ascorbic acid, you apply Vitamin E because these two Vitamins work in synergy, boosting the antioxidant properties of them both! 🙂

I wouldn’t suggest to apply this Vitamin C serum everyday because it is quite aggressive. Once a week should be enough.
It is better to make this treatment in the evening before sleeping (so the skin has time to “recover” all the night) and I would suggest to avoid making this treatment in summer or late spring (it is always negative to use acids on the skin in summertime! They weaken the barrier of the skin and they can make more disasters than positive things if your skin receives direct sun rays in the period of an acid treatment).

Now, after having done a little bit of “terrorism” about this Vitamin C Serum… I can say that I have not misused it and I am very happy about the results!
I used to have some red signs on my skin, left from an old acne, and they are finally gone! 🙂
Also, my skin looks more fresh and firm! 🙂

So don’t misuse this DIY and have a great day! 😉

Hair Conditioner Recipe (and THEORY)

Hello 😀
Today I would like to show you a basic recipe for a good Hair Conditioner 🙂
The formulation for a lotion and an hair conditioner are similar but not same: there are some basic differences that, if not followed, might make you fail.

So!
There is still a Phase A and a Phase B BUT! while in the making of a lotion you add the heated Phase B to the heated Phase A… here you MUST do the opposite!
You must pour the Phase A into the Phase B. This is very important!

The second difference is that there is not a proper Phase C because every extra ingredient (which should be added when the Phase A and B are already emulsified and at room temperature) has to be added singularly… ONE BY ONE! 🙂

Apart from these two big differences, however, everything else is quite same! 🙂

Phase A:
Water to 100 (explanation HERE)
Glycerin 3
Guar Hydroxypropultrimonium Chloride 0.1 (this is a very good ingredient in a hair conditioner or even in a shampoo, but don’t use it at higher concentration than 0.1-0.15% – However if you don’t have it, you can use instead a water where you had infused Mallow or Flax Seeds)
Heat this phase up to 75° (absolutely check the termometer!)

Phase B:
Esterquat 8 (this is a CATIONIC emulsifier, therefore it is different from the emulsifiers which we have in our lotions. It is important that you use an emulsifier specifically for hair conditioning 🙂 this substance in the specific is very good because it is eco-friendly 😉 )
Jojoba oil 2
cetyl alcohol 3.5
stearic acid 1.5
Heat this phase up to 70°

“Phase C” (but remember you have to add them one by one and in this order)
Hydrolized wheat protein 3
Panthenol 1
Poliquaternium-7 2 (this enhances the conditioning ability. If you don’t have it you can skip it)
Preservative 0.5-0.6 (or whichever concentration the preservative you are using needs to be!)
Fragrance oil or Essential oil depending on your taste 😀

Have a great day!!! 😀
