Seiwa Kasei launches 100% natural origin amino acid derivative

Japanese beauty ingredient maker Seiwa Kasei has taken the wraps off Amitose R-green, a 100% natural origin amino acid derivative said to deliver long-lasting moisturization for up to 96 hours.

Amitose R-green, created by binding arginine and glycerin, supports beneficial microorganisms without promoting harmful ones, making it ideal for scalp care and suitable for feminine care applications.

Amitose R-green (INCI: Dihydroxypropyl Arginine HCl, Water, Pentylene Glycol) can be incorporated into a wide range of formulations, including toners, serums, creams, shampoos, and conditioners.

As a multifunctional ingredient, it is suitable for skin care, hair care, and scalp care products, and can also be applied in feminine care products and multi-benefit product designs.

“Today’s cosmetic market demands more than basic moisturization. Consumers expect immediate and long-lasting moisturization, while the skinification trend drives multifunctional solutions for skin, scalp, and intimate care,” said a spokeswoman.

“At the same time, natural origin, sustainability, and high biodegradability have become essential global requirements,” she added.

“By uniting long-lasting moisture, microbiome support, and sustainability, Amitose R-green provides an innovative solution for next-generation formulations.”
