Amitose™ HGA, "Lightening vitamin C", is a novel stable vitamin C derivative produced by binding Vitamin C (ascrobic acid), glycerin and an alkyl group together using SEIWA KASEI's original technology. It provides excellent skin moisture but particularly excels at skin lightening. In fact, Amitose™ HGA skin lightening mechanism is the world first of its kind. First, it inhibits melanin synthesis more effectively than most ascorbic acid derivatives. Secondly, Amitose™ HGA inhibits and reverses melanin transport. Lastly, melanin is degraded by autophagy which won the 2016 Nobel Prize. Those mechanism leads to consequently supress dark spots, a truly unique mechanism in Vitamin C derivatives. Amitose™ HGA can be used in a large variety of formulae : skin toners, transparent gel-serums and emulsions such as creams. This product is preservative free water-soluble ingredient. It is developed and manufactured in Japan by SEIWA KASEI.

Vegetamide™ 18MEA-R, "Plant-derived Liquid Cuticle" has aliphatic cationic compounds of rice peptides with hair conditioning efficacy. The F-Layer, which main component is called 18-MEA, is the barrier structure of hair cuticles, but it can be stripped off due to hair damage. Because Vegetamide™'s structure mimics the structure of the F-Layer, it can repair and restore the hair cuticles to a healthy state and improve its texture. This product is preservative free. It is developed and manufactured in Japan by SEIWA KASEI.

Amitose™ DGA, "Rich-Moisturizing vitamin C", is a novel stable vitamin C derivative produced by binding Vitamin C (ascorbic acid) and two glyceryl groups using SEIWA KASEI's original technology. In addition to inhibiting melanin production it provides ultra moisture to the skin as it strenghtens the cornified cell envelope in the stratum corneum. As a non-ionic ingredient it can be used easily in gel and emuslion formulae such as creams but it is also notably recommended for transparent gel-serums, Vitamin C-rich serum and skin toners. This product is preservative free water-soluble ingredient. It is developed and manufactured in Japan by SEIWA KASEI.

Vegetamide™ 18MEA-NJS, "Plant-derived Liquid Cuticle" has aliphatic cationic compounds of pea peptides with hair conditioning efficacy. The F-Layer, which main component is called 18-MEA, is the barrier structure of hair cuticles, but it can be stripped off due to hair damage. Because Vegetamide™'s structure mimics the structure of the F-Layer, it can repair and restore the hair cuticles to a healthy state and improve its texture. This product is the preservative free. It is developed and manufactured in Japan by SEIWA KASEI.

Amitose™ 3GA, "Anti-aging vitamin C", is a novel stable vitamin C derivative produced by binding Vitamin C (ascorbic acid) and glycerin using SEIWA KASEI's original technology. In addition to providing skin moisture and inhibiting melanin production, Amitose™ 3GA has an excellent anti-oxydant effect. In fact, Amitose™ 3GA acts inside the cell where it decreases oxydanting agents, the reactive oxygen species (ROS). Its intracellular oxydant effect and cost effectiveness make it perfect for serum, high concentration formulae, anti-aging care and many other formulae. This product is preservative free water-soluble ingredient. It is developed and manufactured in Japan by SEIWA KASEI.

The F-Layer, which main component is called 18-MEA, is the barrier structure of hair cuticles, but it can be stripped off due to hair damage. Because Vegetamide™'s structure mimics the structure of the F-Layer, it can repair and restore the hair cuticles to a healthy state and improve its texture. This product is preservative free.

HAZUMI-HADA, "Anti-aging Collagen" is a collagen-derived ingedient, which boosts collagen production. In Japanese, HAZUMI-HADA means plump skin. Indeed, HAZUMI-HADA considerably promotes the production of collagen and as consequence improves the firmness of the skin. The collagen production is even further boosted when HAZUMI-HADA is combined with Vitamin C. It also improves activation of fibroblasts, the cells indispensable to skin collagen production. HAZUMI-HADA is best used a leave-on skin care formulation particularly with Vitamin C. This product is preservative free. It is developed and manufactured in Japan by SEIWA KASEI.
