Silk Amino Acids (90 Da) – Premium Cosmetic Raw Material for Skin and Hair Care
Discover the Benefits of Low Molecular Weight Silk Amino Acids for Moisturizing Creams, Facial Care, Body Washes, and Hair Care Formulations.
1. Product Introduction
Looking for a multifunctional cosmetic ingredient to enhance the moisturizing and conditioning performance of personal care products?
Our Silk Amino Acids are water-soluble amino acid mixtures obtained through the controlled hydrolysis of natural silk fibroin. Featuring an outstanding average molecular weight of approximately 90 Da, this ingredient offers cosmetic manufacturers a distinctive low-molecular-weight silk-derived raw material for developing innovative skincare and haircare products.
Silk fibroin is naturally rich in amino acids, particularly glycine, alanine, and serine. These amino acids contribute to the moisture-binding and conditioning properties that make silk-derived ingredients valuable in cosmetic formulations.
Unlike larger silk protein molecules, our Silk Amino Acids are composed of small amino acid molecules, providing excellent water solubility and flexibility in formulation development.
Available in both white powder and transparent liquid forms, this ingredient can be used in a variety of personal care products, including moisturizing face creams, body lotions, shower gels, body washes, facial cleansers, shampoos, conditioners, and nail care formulations.
The key feature of our product is its approximately 90 Da average molecular weight, making it an important technical specification for cosmetic ingredient selection.
2. Main Features and Cosmetic Benefits
Exceptional Low Molecular Weight – Approximately 90 Da
Molecular weight is an important consideration when selecting silk-derived ingredients for cosmetic applications.
Our Silk Amino Acids have an average molecular weight of approximately 90 Da, distinguishing this ingredient from conventional silk protein and higher-molecular-weight silk hydrolysates.
This low-molecular-weight amino acid composition provides excellent water solubility and makes the ingredient suitable for various water-based cosmetic formulations.
Moisture Binding and Skin Hydration
Silk Amino Acids have hydrophilic characteristics that help attract and retain moisture. They can contribute to maintaining skin hydration and improving the softness of finished cosmetic products.
When incorporated into moisturizing creams, lotions, and facial essences, they help create a smoother and more comfortable skin feel.
Skin Conditioning and Smooth Texture
A good cosmetic ingredient should contribute not only to product functionality but also to the overall user experience.
Silk Amino Acids can help condition the skin and improve the sensory characteristics of skincare formulations. Their moisturizing properties make them particularly suitable for products designed for dry skin and daily skin conditioning.
Hair Conditioning and Improved Manageability
Silk-derived amino acids are also valuable in haircare formulations. They help condition hair fibers, contributing to improved softness, smoothness, and combability.
They can be incorporated into shampoos, conditioners, hair masks, and styling products to enhance the conditioning performance of finished products.
Water Solubility and Formulation Flexibility
Our Silk Amino Acids are suitable for water-based cosmetic formulations and offer flexibility for different product development requirements.
Both powder and liquid formats allow manufacturers to select a suitable raw material form according to their production processes.
