I've been experimenting with my mamey cream formulation now and then, which has evolved a bit. Because I have some Silsense DW-18
in stock, I noted it can be used to make microemulsions and also acts as a co-emulsifier.
The cream without the Silsense was OK but I wanted it thicker, so I made the following changes:
mamey oil ~~~~~~~~~~~~~5%~~~~~~5%
cetearyl alcohol ~~~~~~~~~3%~~~~~~5%
cetyl alcohol ~~~~~~~~~~~1%~~~~~~2%
stearic acid ~~~~~~~~~~~~1%~~~~~~2%
vitamin E ~~~~~~~~~~~~~0.5%~~~~0.5%
Silsense DW18 ~~~~~~~~~0%~~~~~0.7%
glycerol monostearate ~~~~~2%~~~~~2%
The polar components include water at 79% glycerin at 3% and panthenol at 1%.
The result of the changes was that the cream became thinner, rather than thicker. In fact it is so thin it is easily pourable at room temp. The sensorials apart from its watery nature are good, it absorbs quickly and leaves a really luxurious skin sensation. I've got 16.5% of nonpolars including emulsifiers in there, and it's this thin? Presumably it is the silicone ester or microemulsion that's caused this? Looking for opinions.
