A plant peptide ingredient that strengthens hair fibers and balances skincare formulas
Rice protein hydrolyzate is a concentrate of low molecular weight peptides and amino acids derived from breaking down rice protein into smaller fragments. Because these molecules are small, they can penetrate the outer layers of the hair shaft and skin surface, forming a light protective film. This makes the ingredient especially popular in professional hair care manufacturing – shampoos, conditioners, masks, leave-in treatments and styling products. The item belongs to the Hydrolyzed Proteins category, which brings together plant-derived ingredients with a similar mechanism of action.
Across global cosmetic manufacturing, rice hydrolyzate is valued for giving hair flexibility and easier detangling without adding heaviness, which is why it frequently appears in styling creams and finishing serums. In skincare production the compound is used in creams, serums and lotions for face and body, where it supports skin elasticity, contributes to a smoother surface feel and helps retain moisture in the upper epidermal layers. Compared with animal-derived proteins, rice hydrolyzate is considered lighter and less likely to trigger sensitivity, making it a common choice for gentle and baby-care lines. A smaller share of formulations use it in color cosmetics such as foundations, BB creams and lip products, where the protein helps pigments adhere and extends wear time.
Rice protein hydrolyzate should be added during the final, cool-down phase of emulsion preparation, at temperatures not exceeding 40 degrees Celsius, to prevent breakdown of the peptide chains. A typical working dosage ranges from 1 to 5 percent of the total formula weight, depending on the product type and the desired concentration of active peptides. It pairs well with other plant hydrolyzates, such as Bean Protein Hydrolysate, allowing manufacturers to build multi-component blends for hair repair formulas, and with Soy Protein Hydrolysate Gerard's Cosmetic to enhance the moisturizing profile of a recipe. Formulators also combine it with Walnut Shell Hydrolyzate when a light tinting effect is needed in products aimed at darker hair tones.
The 50 ml packaging is intended for home-based cosmetic making, trial batches and small pilot formulations before scaling up to larger production runs. This volume is enough to test the right concentration across several product types, from shampoo to hand cream, without wasting raw material. The ingredient should be stored in a tightly closed container, in a cool dark place away from direct sunlight and heat sources, avoiding freezing and sudden temperature changes. Once opened, the contents should be used within the period specified by the manufacturer, keeping the container clean during each use.

Liquid panthenol 2 ml
Preservative 1 ml
Fragrance oil 0.5 ml
Heat
the water phase with the emulsifier over a water bath until fully melted, then
blend in the almond oil and remove from heat. Once the mixture cools to about
38 degrees Celsius, add the rice protein hydrolyzate, panthenol, preservative
and fragrance, stirring gently until smooth. Pour the finished serum into a
clean spray bottle and let it settle for 24 hours before first use.
