Soy Amino Acids
What is Soy Amino Acids?
Soy Amino Acids consist of a mixture of amino acids obtained through the hydrolysis of proteins extracted from soybeans (Glycine max), a legume plant. This process breaks down large protein molecules into smaller, water-soluble components. In cosmetics, they serve as conditioning agents, primarily in hair care and skincare formulations like shampoos, conditioners, and lotions. They function by forming thin films on the skin and hair shafts, which reduce surface friction, improve slip, and provide a smooth texture. Additionally, their humectant properties help draw and hold moisture, supporting hydration without heaviness. Their mild, amphoteric nature makes them suitable for a wide range of product pH levels, contributing to better sensory attributes and compatibility with other ingredients.
