Liquid Silk 1 L

Why silk protein hydrolysate remains a staple in professional formulation

Liquid Silk in a 1 liter volume is a concentrated hydrolyzed silkworm protein solution that has become one of the most requested raw materials in the global hair and skin care industry. Demand for this ingredient comes primarily from professional cosmetic manufacturers, contract labs, and studios working with medium to large production batches rather than single trial samples. This product belongs to the Hydrolyzed Proteins category, which brings together related plant and animal derived compounds differing in molecular weight and source.

The primary application of liquid silk lies in hair repair formulas: conditioners, masks, leave-in serums, split-end treatments, and heat protection sprays. The hydrolyzed protein fragments penetrate damaged sections of the cuticle and fill in gaps left by chemical perms, coloring, or frequent heat styling, giving hair a visibly thicker, smoother appearance and easier combing. A second major field of use is facial and body skin care, including anti-aging creams, emulsions, toners, and serums, where silk protein forms a thin surface film that holds moisture and creates a smooth, silky feel on contact. The ingredient is also widely used in shampoos, styling products, and even certain color cosmetics, where a slip effect during application is desired.

Liquid silk pairs well with other hydrolyzed proteins, allowing formulators to build complex multi-action blends. Combined with Ginseng Protein Hydrolyzate, it produces strengthening formulas aimed at hair follicle support and growth stimulation, while adding Horse Chestnut Fruit Hydrolysate enhances the toning effect for scalp circulation. For lighter everyday formulas, liquid silk is frequently paired with Wheat Protein Hydrolysate, delivering balanced hydration without weighing hair down.

The ingredient should be added at the final stage of emulsion or water phase preparation, at a temperature not exceeding forty degrees Celsius, to prevent breakdown of the protein fragments. Recommended usage typically ranges from one to five percent depending on the product type: lighter toners and sprays require the lower end, while intensive repair masks call for higher concentrations. The one liter format is designed for studio and small-scale industrial production where consistent raw material supply matters more than frequent repackaging. Store the product in a tightly sealed container, in a cool place away from direct sunlight, avoiding temperature fluctuations and prolonged air exposure once opened.

Beyond cosmetics, silk hydrolysates are also used in textile finishing processes and in certain household chemical formulations requiring a fiber-softening effect. Within home cosmetic making, liquid silk is valued by hobbyists who add it to liquid soap bases and cream formulas for a softer after-feel on the skin.

Liquid Silk 25 g

Wheat Protein Hydrolysate 5 g

Glycerin 6 g

Panthenol 3 g

Distilled water 53 g

Preservative 8 g

Warm the water to about thirty five degrees Celsius and dissolve glycerin and panthenol into it, stirring until fully combined. Let the mixture cool to room temperature before slowly adding liquid silk together with wheat protein hydrolysate, stirring gently to avoid foaming. Finally blend in the preservative, pour the finished conditioner into a spray or pump bottle, and apply to damp hair before styling.
