Glycine Soja (Soybean) Peptide

Product Description

Direct factory supply of high-purity Glycine Soja Peptide (INCI: GLYCINE SOJA PEPTIDE), the ultra-membrane filtered di-/tri-peptide fraction from Glycine soja L. soybean protein with batch COA traceability for bulk cosmetic sourcing.

CosIng lists this plant-derived peptide for film forming, skin conditioning, and hair conditioning. The low-molecular di-/tri-peptide fraction deposits breathable films on skin and keratin, supporting moisture retention and formulation tolerance in aqueous bases.

Widely used in hair conditioners, essences, and barrier moisturizers, soybean peptides offer plant-sourced conditioning with simpler handling versus longer synthetic signal peptides in clean-label beauty lines.

Key Benefits & Applications

Glycine Soja Peptide delivers ultra-filtered soybean di-/tri-peptides for film-forming hydration, barrier support, and hair conditioning in B2B formulations.

• Film-Forming Moisture Shield: Forms breathable peptide films that reduce transepidermal water loss on treated skin.
• Deep Skin Conditioning: Softens and hydrates stratum corneum in aqueous serums and essence systems.
• Sustained Hydration Retention: Supports long-lasting moisture balance in cream and lotion applications.
• Hair Cuticle Conditioning: Deposits on keratin fibers to improve slip and combability in rinse-off conditioners.
• Barrier-Friendly Tolerance: Small peptide fraction suited to sensitive-skin and daily moisturizer lines.

Formulation Guidelines

Formulate Glycine Soja Peptide in water-rich systems where plant-derived di-/tri-peptide film forming and conditioning are required.

• Use 1–5% w/w in creams and serums; 0.5–2% Typical in essences and hair conditioners.
• Maintain pH 4.5–7.0; pre-dilute in water phase before adding high-level surfactants.
• Add below 60°C in cool-down phase to preserve peptide film-forming performance.
• Compatible with glycerin, panthenol, and hyaluronic acid; avoid strong anionic systems near isoelectric point.
• Ideal for hair masks, barrier moisturizers, clean-label essences, and conditioning leave-on treatments.
• Synergy: Beta-Glucan strengthens film hydration when blended with soybean peptides in sensitive-skin toners at 0.5–2%.
