KWSLHS-30 is a mild amino acid-based anionic surfactant derived from hydrolyzed silk protein. A silk-derived amino acid surfactant designed for mild cleansing, soft skin feel and improved hair after-feel in personal care formulations.
Compared with common silk protein surfactants on the market, KWSLHS-30 is designed with a lighter color profile, low sodium chloride content and stable active content. This makes it suitable for clear or light-colored cleansing products, where color, salt level and formulation stability are important.
Key Benefits of Sodium Lauroyl Hydrolyzed Silk (KWSLHS-30)
- Silk-derived and naturally inspired: KWSLHS-30 is derived from hydrolyzed silk protein. Silk protein contains amino acids that help form smooth, glossy and flexible films on the skin and hair surface.
- Mild cleansing with low irritation: As an anionic amino-acid surfactant, it provides gentle cleansing performance while helping reduce the harsh feel often caused by stronger traditional surfactants.
- Silky after-feel: It leaves a smooth, clean and lightweight sensory feel after rinsing, making it suitable for premium facial cleansers, body washes and mild shampoos.
- Moisturizing support: Silk sericin is rich in amino acids with hydroxyl groups, which are helpful for moisture retention. This supports a hydrated, comfortable skin feel and helps hair feel soft and smooth.
- Film-forming and gloss-enhancing: The silk-derived structure can help form a fine protective film on hair and skin, improving gloss, smoothness and combing feel.
- Good formulation compatibility: KWSLHS-30 offers good solubility and can be used with amphoteric, nonionic and other amino acid-based surfactants to build mild cleansing systems.
- Light color and controlled salt level: Its colorless to pale yellow appearance and low sodium chloride profile make it suitable for transparent, light-colored and premium mild cleansing formulas.It helps reduce the risk of viscosity fluctuation and formulation instability caused by excessive inorganic salts.
- Biodegradable and environmentally friendly: Suitable for mild personal care products with a natural-origin and eco-conscious positioning.

Choosing between related INNO products
KWSLHS-30 is recommended when the formula needs a silk-derived mild surfactant with a smooth after-feel, light color and low salt profile. For formulas focused mainly on rich foam, viscosity building or lower cost, it can also be combined with glutamate, glycinate, taurate or amphoteric surfactants.
Frequently asked questions
Can KWSLHS-30 be used as the main surfactant in a cleanser?
It can contribute mild cleansing and foam, but in most commercial formulas it is recommended as part of a surfactant blend. Formulators often combine it with glutamate, glycinate, amphoteric or nonionic surfactants to balance foam, viscosity, cleansing power and cost.
Will the low salt content help with formulation stability?
Yes. Lower sodium chloride content can reduce the risk of salt-related viscosity fluctuation, cloudiness or compatibility issues, especially in transparent or light-colored mild cleansing systems. Final stability still needs to be checked in the complete formula.
Is it suitable for clear or pale-colored products?
Yes. KWSLHS-30 is a colorless to pale yellow liquid, making it suitable for transparent facial cleansers, clear body washes, light-colored shampoos and premium mild cleansing products.
Can it improve hair feel?
Yes. The silk-derived structure can help improve smoothness, softness and gloss. It is especially suitable for mild shampoos, scalp care products and formulas that need a cleaner but less dry after-wash feel.
Is it suitable for sensitive-skin or baby cleansing products?
It is suitable for mild cleansing systems targeted at sensitive skin or baby care. However, the final product should still complete irritation, stability and preservative challenge testing according to the brand’s safety requirements.
Does KWSLHS-30 contain preservatives?
Please confirm with the latest TDS, SDS or COA before production, because preservative status may depend on the specific batch and supply specification.
Can it be used in leave-on products?
Yes, the recommended dosage for leave-on products is 0–2%. For leave-on use, compatibility, skin feel and local regulatory requirements should be checked before final application.
What documents can you provide before purchase?
We can provide TDS, SDS and COA upon request. Sample testing is recommended before bulk purchase, especially for transparent systems, low-temperature storage conditions or formulas with complex fragrance, polymer or preservative systems.
