Hydrolyzed Soy Protein Liquid BLP

Film-Forming Plant Protein for Smoother Skin and Hair

Soy protein is one of the most studied plant proteins in personal care. In hydrolyzed form it dissolves in water and leaves a fine film that helps smooth the feel of skin and hair. Hydrolyzed Soy Protein Liquid BLP brings that performance in a format you can pour and weigh directly.

Why Formulators Choose Hydrolyzed Soy Protein Liquid

Soy is a dependable mid-range protein: more film than amino acids, lighter than heavy whole proteins. It supports both "smoothing" skin claims and "strengthening" hair claims, making it a great dual-use ingredient for brands with small inventories.
