Have anyone here tried formulating with SEPPIC's Simulgreen 18-2 (inci: Hydroxystearyl Alcohol and Hydroxystearyl Glucoside)? Here is the tech sheet. First thing that peaked my interest was that it’s supposedly “invisible” on application and does not produce the dreaded soaping effect. It’s also stable across a broad range of pH (3-10), can withstand electrolytes and at 3 % it spontaneously creates a cream texture.
As a home crafter, this product would make my life much simpler, so I obviously decided to try it. I have not been pleased with the results. It claims to be able to emulsify a large amount of oil at low levels (1-3 %), but my simple formula with just 8 % oil, separated after only a few days. Prior to it separating, the viscosity was too low and did not provide the cream texture it claims to. It’s probably worth mentioning that I did not add any stabilizing ingredients because I wanted to see how well it behaved on its own.
So after that failed, I tried again, this time with a larger oil phase, 20 %, and more emulsifier, 4 %, even though the tech sheet recommends between 1-3 % but then provides sample recipes that uses 4 %. The final product ended up being a bit thicker, but not nearly thick enough. It’s now one day later and I can already tell that it’s starting to separate.
Another annoyance is that I have not been able to find clear instructions on how to use it. The tech sheet provides sample recipes, but does not provide any explanation of the methods. So far I’ve come across sites like Lotioncrafter which provide some guidance, but parts of their info conflicts with the tech sheet.
