Silk Amino Acids are a unique blend of amino acids derived from hydrolyzed silk fibers. Known for their small molecular size, these water-soluble amino acids penetrate deep into the skin and hair, offering intense hydration, improving texture, and promoting elasticity. Perfect for use in a variety of cosmetic formulations, including serums, shampoos, conditioners, and body lotions

Key Features & Benefits

• Superior Penetration: Due to their small molecular size, Silk Amino Acids penetrate deeper into the hair shaft and skin layers compared to larger proteins, offering enhanced hydration and protection.
• Moisture Retention: These amino acids bind to moisture, helping to maintain skin hydration and prevent water loss from the hair. This leads to smoother, more supple skin and softer, more manageable hair.
• Hair Manageability and Shine: Silk Amino Acids improve hair flexibility, reduce frizz, and impart a silky, natural shine, enhancing overall manageability.
• Skin Hydration: Helps boost the skin's ability to retain moisture, plumping the skin and reducing the appearance of fine lines and wrinkles.
• Biodegradable & Eco-Friendly: As a natural ingredient, Silk Amino Acids are biodegradable and fit seamlessly into sustainable product development.

How Silk Amino Acids Differ from Proteins

While proteins like hydrolyzed silk are larger molecules that mainly form a protective film on the skin and hair, Silk Amino Acids consist of smaller building blocks that can penetrate deeply. This allows for improved hydration, repair, and flexibility, making them more effective in deeply nourishing formulations.

Suggested Uses

• Shampoos & Conditioners: Improves hair’s elasticity and manageability while adding softness and shine.
• Serums & Creams: Enhances moisture retention, improving skin smoothness and reducing the appearance of fine lines.
• Body Washes & Facial Toners: Helps maintain skin hydration for a smoother, radiant appearance.
• Cosmetic Applications: Adds silkiness to mascaras, lipsticks, and other leave-on formulations.

Recommended Usage

• Usage Rate: 1% – 2.5% in final formulations.
• Formulation Tip: Add in the cool-down phase (below 40°C) to preserve the integrity of the amino acids. Suitable for use in water-based formulations but not in oil-based systems.

Storage & Handling

• Storage: Keep in an airtight container at room temperature. Avoid exposure to heat and direct sunlight. Do not freeze.
• Shelf Life: Best used within one year from the date of purchase when stored in optimal conditions.
