Silk Amino Acids for Cosmetics – Ultra-Low Average Molecular Weight of 90 Da

Premium Low-Molecular-Weight Silk Amino Acids for Skincare, Face Creams, Body Washes, and Hair Care

Product Overview

Silk Amino Acids are specialty cosmetic ingredients derived from the hydrolysis of natural silk proteins. With an average molecular weight of approximately 90 Da, our Silk Amino Acids are designed for cosmetic formulators seeking a versatile ingredient for moisturizing, skin conditioning, and hair conditioning applications.
Silk proteins naturally contain amino acids such as glycine, alanine, and serine. These components are valued in personal care formulations for their moisture-related properties and ability to contribute to a soft, smooth skin and hair feel.
The key distinguishing feature of our product is its average molecular weight of approximately 90 Da, making molecular weight an important specification when evaluating this grade of silk amino acids for cosmetic applications.
Suitable for a wide range of personal care formulations, Silk Amino Acids can be used in facial creams, body lotions, moisturizing emulsions, facial cleansers, body washes, shampoos, conditioners, hair styling products, and nail care products.

Key Benefits of Silk Amino Acids

1. Moisturizing and Moisture Retention

Silk Amino Acids help attract and retain moisture, making them valuable ingredients in formulations designed to maintain skin hydration. They can contribute to a softer, smoother skin feel and enhance the moisturizing performance of creams, lotions, and other personal care products.

2. Low Average Molecular Weight of Approximately 90 Da

Molecular weight is an important technical parameter when comparing silk-derived cosmetic ingredients.
Our Silk Amino Acids feature an average molecular weight of approximately 90 Da, providing a specific technical characteristic for cosmetic raw material selection. This low-molecular-weight profile is relevant to formulators developing water-based and moisture-focused cosmetic products.

3. Skin Conditioning and Smoothness

Silk Amino Acids function as skin-conditioning ingredients that help maintain skin in good condition. When incorporated into creams and lotions, they contribute to the overall sensory quality of the formulation, helping create a soft, smooth, and comfortable after-feel.

4. Hair Conditioning and Softness

In haircare formulations, Silk Amino Acids can condition the hair surface, helping improve softness, smoothness, and manageability. They are suitable for shampoos, conditioners, hair masks, and styling products where conditioning performance is important.

5. Versatile Cosmetic Applications

Silk Amino Acids can be considered for both leave-on and rinse-off products, giving cosmetic manufacturers flexibility when developing moisturizing skincare, cleansing products, and haircare formulations.
