ALT Treatment

ALT TREATMENT is based on alkoxysilane, is one of the staple silicone surface treatments used in the cosmetics industry. “Silane” surface treated pigments and mineral fillers provide cosmetic chemists with value-added performance at a relatively low cost. In liquid foundations and CC creams, they provide strong and vivid colors, excellent skin adhesion, and a silky soft feel. Silane surface treated TiO2 and ZnO sunscreens typically exhibit higher SPF and transparency due to lower agglomeration and ease of dispersibility into the oil phase.

VLI/LT/VLT Lecithin Surface Treatment

Miyoshi Kasei’s original patent for Lecithin Treatment was based solely on egg yolk lecithin derived from chicken eggs.  When cosmetic companies wanted a plant derived lecithin treatment, Miyoshi America, Inc. was able to find a hydrogenated lecithin derived from Soy Beans, without the drawbacks of previously available vegetable derived lecithin treatments. Hydrogenated egg yolk lecithin shows the same effect of emulsification and moisturizing as natural, unhydrogenated yolk oil.
