Aminosyl™ NL50 is a natural moisturizing factor (NMF) that provides stronger hydrating power than glycerin, sorbitol or propanediol. Sodium PCA is the sodium salt of pyroglutamic acid, although uncommon, it is found naturally in many proteins. Recommended applications are creams and shampoos. Aminosyl™ NL50 can be used on many skin care and hair care products to provide a complimentary moisture binding in cells. It is a highly effective water-absorbent as evidenced by its ability to hold several times its weight in water making it a very effective humectant. In fact, it is a stronger hydrating agent than many traditional substances such as glycerin and propylene glycol. Aminosyl™ NL50 is also highly effective in hair care for the reduction of static electricity.
