I have long wanted to add a ceramide or pseudo ceramide to my emulsions. Due to cost and lack of hard core scientific data...I had a great deal of interest in the latter, cheaper version (pseudo ceramides). However....I was not given the time of day from the couple of mfg's I contacted.
As my formulating has morphed with a strong influence of some Swiss PhD, I am looking at my formula...and seeing L-Proline and several natural sources of palmitic acid....and wondering...have I accidently back doored (or been carefully steered) my way into something very similar to pseudo ceramides? Sometime I think the Swiss genius just likes to see how long it takes me to figure out where he has dropped me off at.
I have discovered....with my daily formulation adventures...that I have recreated through simple trial and error, several high dollar/ high functional combinations that the big boys are selling. Not by looking at these products on ULP and trying to mimic.....Just buying tons of ingredients, and trying them in existing formulas, evaluating what worked and felt the best. Later on, I discover that these combos had already been created.
I merely consider this validation of my sensory skills. (That is the only skill I believe I hold as a formulator...I can feel a .5% ingredient change...like day and night.)
