What it is
This ingredient is produced by hydrolyzing quinoa, breaking its proteins and other constituents into smaller peptides and amino acids that are more readily soluble and skin-compatible. It is used as a plant-derived conditioning agent and can contribute to a smooth, conditioned surface feel, making it popular in vegan and plant-forward formulas. In sunscreens it functions as a supporting botanical, not as a UV filter.
Safety & warnings
Hydrolyzed quinoa is generally well tolerated at cosmetic use levels. As a plant protein hydrolyzate, sensitization is possible but uncommon; those with known grain or plant sensitivities may wish to patch test. It is not an oil and is not linked to comedogenicity.
Origin & sourcing
Plant-derived, sourced from the quinoa grain (Chenopodium quinoa) and then hydrolyzed into smaller fragments such as peptides and amino acids.
