Hydrolyzed Soy Protein
What Hydrolyzed Soy Protein is & what it does
A soy-derived protein that conditions and hydrates, forming a smoothing film and supporting a softer, more even-looking surface. It is gentle and nourishing.
What does Hydrolyzed Soy Protein do in skincare?
Hydrolyzed Soy Protein is a mix of amino acids and small peptides from soy that acts as a conditioning and film-forming agent. It can bind water and leave a smoother surface feel on skin and hair. It is used mainly for a temporary softening and conditioning effect.
Is Hydrolyzed Soy Protein natural or synthetic?
It is plant-derived, made by breaking down soy protein into smaller fragments through hydrolysis. Because the source is soybeans, it is generally considered a naturally sourced, vegan-friendly ingredient. The exact preparation can vary by supplier.
Is Hydrolyzed Soy Protein safe?
Hydrolyzed Soy Protein is commonly used in cosmetics and is generally regarded as well tolerated. People with a known soy allergy may prefer to check the label and approach soy-based ingredients with caution. As with any ingredient, a patch test is reasonable if you have relevant allergies.
