What it is
This ingredient is a mixture of free amino acids obtained by hydrolyzing protein from rice. Amino acids are natural components of skin's own moisturizing factor, so rice amino acids function as humectants that help bind water and as skin-conditioning agents that leave skin feeling soft and smooth. They are commonly used in moisturizers, sunscreens, and hair products for their lightweight, water-soluble conditioning effect.
Safety & warnings
Rice-derived amino acids are generally well tolerated and considered low risk for irritation or sensitization at cosmetic use levels. They are water-soluble and non-comedogenic. People with documented rice allergy may wish to exercise caution, though reactions to topical hydrolyzed rice ingredients are uncommon.
Origin & sourcing
Natural-derived. It is produced by hydrolyzing rice protein into its constituent amino acids, yielding a plant-based, water-soluble ingredient.
