Thanks guys,
Sorry, but I guess I wasn’t clear about a few things. What I am trying to find out is about a particular kind of shaving cream that is soap based and made with Fatty Acids like Stearic and Myristic Acid as well as Coconut Oil or Coconut Fatty Acids which are saponified by KOH, NaOH and TEA. This type of lathering cream has a history of about 100 years and many of the formulas that are out there in the market still contain all of these more “natural” soap based ingredients and no surfactants. Since they use Fatty Acids they do not contain the amount of glycerin that it needed in the formula to keep the creamy lather “attached” to the skin for the length of time needed to complete the shave, help maintain the “moisture” level and provide the type of consistency needed for that purpose. The “listing” that was from a formulation was just pointing out that those two options were considered “humectants and moisturizers” but did l some more research I found information listed on a familiar site by this gentleman named Perry Romanoski!
“Sorbitol - This is a 6 Carbon sugar that has 6 -OH groups. It can be derived from glucose so can maintain a natural story. It is more hygroscopic than glycerin and doesn’t suffer from the stickiness problem. However, it is more expensive which is why it is not used as extensively as glycerin or propylene glycol.”
This provided the information I was looking for and showed me why sorbitol was chosen as a “substitute” for glycerin from a shaving cream formula that it sold in tubular form! Sorry that I wasn’t as clear as I could have been but I appreciate your input and the information from that Romanoski gentleman! Regards, David
