My Lab Notes: Phase C—The “Cool Down” & Active Ingredients
Hello Hello! 😀
If Phase A and B are the “body” of my cream, then Phase C is the personality! This is the “Cool Down” phase where I add all the fun stuff, but it’s also the part that makes me the most nervous. Why? Because most of these ingredients are total divas—they hate heat!
The “Waiting Game” Protocol
Sips water. Patience is everything here. I’ve learned that I absolutely have to wait until my emulsion drops below 40°C. If I get impatient and add things too early, I’m basically just cooking my expensive actives!
-
My Checklist: I usually keep my total “active load” under 10% to make sure the emulsion stays stable and doesn’t get “cranky.”
1. The “Antioxidant Cocktail” Theory
I’ve been reading that it’s better to use a team of antioxidants rather than just one.
-
My Observation: Mixing Vitamin E (Tocopherol) with something like Resveratrol seems to create a much stronger defense. It’s like they protect each other while they protect the oils in my cream!
2. Acids & The pH Balance
I use things like Lactic or Citric acid to either exfoliate or just fix the pH.
-
Safety Note: My notes are very strict about this—if I use chemical exfoliants like Salicylic acid, those batches are for NIGHT USE ONLY. I don’t want to mess with photosensitivity!
3. Niacinamide: The “Flushing” Constraint
Niacinamide is a hero in my oily-skin research (I usually use 1–4%), but it has a very specific rule: pH 5.0 to 5.5. * The Risk: I’ve documented that if the pH goes too high or too low, it can turn into Nicotinic Acid. If that happens… PHEW! It can cause the skin to flush and turn red. Not what I’m going for! 😀
4. Soothing & The “Grit” Problem
I love adding Panthenol (B5) and Allantoin for that soothing feeling.
-
Lab Lesson: Allantoin is a tricky one! It only dissolves at 0.4%. I’ve had batches where I used too much and ended up with “grit” in the cream. It felt like a scrub instead of a lotion! Now I’m much more careful with my measurements.
5. Eye Area Experiments (The Caffeine Boost)
For my eye creams, I’ve been experimenting with Caffeine and Escin. They are fascinating because of their “vasoprotective” properties—basically trying to help with puffiness and drainage.
**The “Reality Check” on Sourcing 😉 **
This is where my inner detective comes out. Marketing can be so deceptive!
-
The Q10 Case Study: Pure Coenzyme Q10 is a bright, intense yellow. Even at 0.1%, it turns the cream yellow.
-
My Thought: When I see a “Pure White” Q10 cream in a store, I just smile and shake my head. I know the concentration must be almost zero!
-
Check the SDS: I’ve learned to always check the Safety Data Sheet. “Liquid Q10” is often mostly filler with just a tiny bit of the real stuff. I want to know exactly what I’m putting in my beakers!
It really is a science, and every time I cool down a batch, I feel like I’m learning a new secret. It’s all in my hands! 😉
HAVE A GREAT DAY! 😄
