Hydrolyzed rice protein

Hydrolyzed rice protein (CAS 156715-40-1), also marketed under trade names such as Gluadin R and Colhibin, is derived from rice endosperm protein broken down into peptides and amino acids through enzymatic or chemical hydrolysis.

In personal care and food applications, it functions as a film-forming humectant and surface-conditioning agent that binds to hair, skin, or food matrices to improve texture and moisture retention.

In hair care formulations, including shampoos, conditioners, and leave-in treatments, it adsorbs onto damaged keratin surfaces to reduce breakage and improve combability. This makes it a versatile ingredient for restorative products.

Skin care manufacturers incorporate it into serums and moisturizers where its low molecular weight peptide fractions support hydration and surface smoothing without leaving an occlusive residue on the skin.

In food and nutrition, it serves as a plant-based protein supplement and flavor precursor in savory applications, including broths, seasonings, and protein-enriched beverages. It is highly valued for its nutritional profile.

Pharmaceutical formulators also use it as a clean-label excipient in oral nutritional products targeting allergen-sensitive populations. It is supplied as a liquid concentrate or spray-dried powder for various uses.

The powder form is preferred for dry blending and capsule applications. Standard grades include food-grade and cosmetic-grade specifications, with some suppliers offering defined molecular weight fractions for specific targets.

Organic-certified and allergen-free variants are available for clean-label and hypoallergenic product lines. These options ensure compliance with modern consumer demands for high-quality, sustainable ingredients.
