NAI/NAID

Over 15 years ago, Miyoshi Kasei introduced its novel Amino Acid surface treatment technology for cosmetic applications. This patented technology, designated NAI (replacing the original AI, animal-derived treatment) is based on the chemical bonding of Disodium Stearoyl Glutamate to pigments and substrates. The NAI treatment was quickly embraced worldwide because of its unique benefits. The Compatibility of NAI treated pigments in silicone-based systems has been amply demonstrated by their usage in a number of commercially available W/S liquid foundations. NAI and NAID is longwearing and provides a moist, dewy feel while being much easier to disperse in oils and silicones.
