Walnut Shell Hydrolyzate 1 L

A Natural Toning Extract from Walnut Shells Built for Bulk Production

Walnut Shell Hydrolyzate in a 1 liter format is designed for studio and industrial manufacturers who need a reliable volume of raw material for consistent batch production. This ingredient belongs to the Hydrolyzed Proteins category, which brings together water soluble plant and animal derived extracts valued for their concentrated active fractions and ease of dosing in finished formulas.

The primary global demand for walnut shell hydrolyzate comes from the cosmetic industry, where it has long been used in toners and rinses for dark hair, giving a natural chestnut tone and visible shine without harsh dyeing chemicals. Thanks to natural tannins and juglone content, the extract is also applied in self tanning products and bronzing emulsions, where it delivers a gradual skin darkening effect combined with a mild toning result. Beyond that, the hydrolyzate is used in lotions and toners formulated for oily and problem skin, thanks to its astringent and sebum balancing properties.

A separate area of application is the textile and leather industry, where extracts from walnut shells have traditionally served as a natural dye and mordant, producing a stable brown coloration on fabrics and leather. In the food sector, diluted hydrolyzate is occasionally used as a natural flavoring and coloring agent for confectionery and beverages, although this use case is far less widespread than its cosmetic applications.

The hydrolyzate combines well with other plant and animal derived extracts. In complex hair care formulas it is frequently paired with Horse Chestnut Fruit Hydrolysate, which reinforces the toning effect and supports scalp microcirculation. For rejuvenating and restorative blends, formulators often add Placenta Hydrolysate, while Sesame Protein Hydrolysate is used to soften texture and enrich the amino acid profile.

The recommended dosage of walnut shell hydrolyzate ranges from 3 to 10 percent of the total formula weight, depending on the desired intensity of toning. It should be added at the final stage of preparation, into the water phase, at a temperature not exceeding 40 degrees Celsius, to avoid degrading heat sensitive compounds. Store the product in a tightly sealed container, in a cool dark place away from direct sunlight and heat sources, which helps maintain the stability of its active components throughout the stated shelf life.
