Hello everyone! 🙂
Today I talk about how to formulate a Solid Shampoo.
This is NOT a natural soap, it is a Syndet (synthetic detergent) made with powder surfactants and other ingredients. A normal soap won’t work well as a shampoo, no matter how many expensive oils you add to it or how much love you put into soap-making.
If you want to make a decent solid shampoo, it must be a syndet. 😉
The advantages of a shampoo bar are that it is compact, it doesn’t weight much, it is easy to use, easy to carry around (on a plane for example)… Yet, it is not at all common to find one in the stores.
The reasons for this are many but here are the main ones:
A Solid Shampoo is made with an extremely high percentage of surfactant matter (55%-85%) and this makes the production costs fly very high as well.
But this is not all: a shampoo bar looks extremely similar to a simple and cheap soap and therefore people don’t give to it even the same value they give to, let’s say, a fancy bottle of liquid shampoo (even if the liquid shampoo costs way less, to produce, than the solid one).
These two things, combined, already don’t make for a winning product…
