Features

COS-EB3, or Tocopheryl Nicotinate, is a derivative in which nicotinic acid (vitamin B3) is combined with tocopherol (vitamin E), resulting in improved oxidative stability of tocopherol. It is a surfactant-type material that possesses both the lipophilic properties of tocopherol and the hydrophilic characteristics of nicotinic acid.

Key Features

  • Provides skin barrier reinforcement, improved elasticity, and skin-slimming effects based on the strong antioxidant properties of vitamin E and the blood circulation–enhancing effects of nicotinic acid.
  • Effectively works on skin damaged by UV exposure, aging, irritation, or dryness, and is used in various skincare products such as moisturizers and creams.
  • A multifunctional ingredient applicable to hair care products such as shampoos and conditioners, promoting skin regeneration and hair growth.
