Silk Protein Hydrolyzate 1 L

Scaling up hair and skin care formulas with liquid silk protein hydrolyzate

Silk protein hydrolyzate is a water-soluble concentrate of amino acids and short peptides produced by controlled breakdown of natural silk fibers. Because of their small molecular size, these fragments penetrate the upper layers of skin and the hair shaft, temporarily filling micro-damage and forming a thin protective film that improves surface smoothness. This raw material belongs to the Hydrolyzed Proteins section, where formulators find comparable functional ingredients for professional recipes. The 1 liter packaging is aimed at studio and industrial manufacturing, letting technologists run continuous batches of shampoos, conditioners, masks, serums and lotions with a declared silk protein content.

The leading global application of silk hydrolyzate is professional hair care. It is widely used in reconstructing shampoos, leave-in serums, heat protection sprays and masks for damaged or color-treated hair, since it smooths the cuticle, adds elasticity and makes combing easier without weighing hair down. The second major direction is skin care for face and body, where the hydrolyzate is added to creams, emulsions, toners and serums for a firming and plumping effect, as well as after-sun products and formulas for sensitive skin thanks to its gentle conditioning action. A smaller but steady demand comes from color cosmetics, where the ingredient helps retain moisture in foundations and primers, and from selected household chemistry recipes for gentle fabric care.

Silk hydrolyzate blends well with other protein components of the line, allowing manufacturers to combine several hydrolyzates in one formula for a stronger synergistic effect. It is often paired with Beer Yeast Protein Hydrolysate, which additionally supplies B-group vitamins to hair, and with Almond Hydrolyzate for extra skin softening in serums and creams. For lighter styling textures a combination with Wheat Protein Hydrolysate is recommended, since it reinforces the film-forming effect.

The ingredient should be added during the cooling stage of the emulsion or water phase, at a temperature not exceeding 40 degrees Celsius, to preserve the peptide structure. Typical working dosage for shampoos and conditioners is between 1 and 3 percent of total formula weight, while serums and concentrates can go up to 5 percent. The hydrolyzate remains stable across a broad pH range and tolerates preservatives, plant extracts and emollients without stability issues. Store the concentrate in a tightly closed container, in a dry and cool place away from direct sunlight, to keep the declared active content stable throughout the shelf life. For large-volume production it is important to reseal the container tightly after every withdrawal to prevent oxidation and loss of efficacy.

Reconstructing leave-in spray for weakened hair

Distilled water 850 ml

Silk protein hydrolyzate 40 ml

Wheat protein hydrolysate 20 ml

Glycerin 30 ml

Panthenol 20 ml

Preservative 10 ml

Fragrance oil 5 ml

Combine distilled water with glycerin and panthenol, then warm the mixture gently to about 35-40 degrees Celsius to help the humectants dissolve fully. Remove from heat and stir in the silk protein hydrolyzate together with the wheat protein hydrolysate until the blend is uniform. Finally add the preservative and fragrance oil, pour the finished spray into fine-mist bottles and let it rest for a day before use to allow the ingredients to fully integrate.
