Silk Amino Acids Powder For Skin Cosmetics Raw Material Hair Benifits

Silk Amino Acids: The Ultimate Cosmetic Ingredient for Hydration and Repair

Silk amino acids (SAAs), also known as silk essence or silk hydrolysate, are a premium functional ingredient derived from natural silkworm cocoons. With a unique combination of low molecular weight, high solubility, and exceptional moisturizing properties, SAAs are revolutionizing the cosmetic industry. This white powder, which transforms into a clear liquid upon water dissolution, is widely used in formulations such as shampoos, serums, lotions, and skincare treatments. Packaged in eco-friendly kraft paper bags or 1kg aluminum foil pouches (customizable upon request), SAAs meet the demands of both manufacturers and environmentally conscious brands.

Key Benefits of Silk Amino Acids in Cosmetics

Deep Hydration & Moisture Retention
SAAs penetrate the hair cuticle and skin’s upper layers effortlessly due to their low molecular weight. They bind to keratin in hair, forming a protective barrier that locks in moisture, reduces breakage, and enhances manageability. For skin, SAAs replenish hydration, soften texture, and minimize transepidermal water loss, making them ideal for dry or irritated skin.

Damage Repair & Anti-Aging Properties
Rich in glycine, alanine, and serine (over 85% combined content), SAAs stimulate collagen synthesis and repair damaged tissues. These amino acids also act as precursors to glutathione, a potent antioxidant that combats UV damage, reduces wrinkles, and delays signs of aging. Tyrosine, another component, supports cognitive health by potentially mitigating Alzheimer’s risks.

Frizz Control & Smoothing Effects
In hair care, SAAs coat strands to reduce frizz, eliminate flyaways, and impart a silky-smooth finish. They also improve length retention by preventing split ends and mechanical damage.

Detoxification & Skin Protection
Glycine aids in detoxifying carcinogenic compounds, while alanine supports liver health by accelerating alcohol metabolism. SAAs further shield skin from environmental stressors and UV radiation.

Production Process: Sustainable and High-Purity

SAAs are manufactured using a rigorous, eco-friendly process to ensure premium quality:

Raw Material Preparation: Fresh silkworm cocoons are degummed in boiling water to remove sericin.

Hydrolysis & Enzymatic Treatment: The fibers undergo hydrolysis with 5M sulfuric acid and papain enzyme to break down proteins into amino acids.

Purification: Multiple filtration steps (membrane, resin exchange, activated carbon, and diatomaceous earth) remove impurities and achieve a clear, colorless solution.

Concentration & Drying: The liquid is concentrated and spray-dried into a fine white powder.

Quality Assurance: Each batch undergoes strict testing for amino acid content (≥90%), pH (5–7), heavy metals (lead, arsenic, mercury), and microbial safety.

Applications in Cosmetic Formulations

Hair Care:

Shampoos/Conditioners: Enhances shine, reduces breakage, and detangles.

Serums/Masks: Repairs split ends and strengthens hair follicles.

Skincare:

Moisturizers/Cleansers: Boosts hydration, improves elasticity, and soothes irritation.

Anti-Aging Serums: Minimizes wrinkles and evens skin tone.

Foundations: Leaves skin velvety-smooth.

Custom Solutions: SAAs can be tailored for specific formulations, such as leave-in treatments or sunscreens.

Quality Certification & Safety

SAAs comply with international standards (e.g., SB/T10407-2007) and undergo rigorous third-party testing. Key metrics include:

Amino Acid Content: 93.56% (exceeds the ≥90% requirement).

Glycine + Alanine + Serine: 87.56% (surpasses the ≥76% threshold).

Safety: Heavy metals (lead: 0.31 mg/kg; arsenic: 0.16 mg/kg) and microbial contaminants are well below permissible limits.

Consistency: pH 5.3, low residue (2.3% ash content), and minimal moisture loss (2.2%).

Packaging & Customization

To cater to diverse client needs, SAAs are available in:

Standard Packaging: 1kg aluminum foil bags (moisture-proof and light-resistant).

Eco-Friendly Option: Recyclable kraft paper bags.

Custom Solutions: Adjustable sizes, branding labels, or bulk quantities.
