Landnutra's Cosmetic Grade Hydrolyzed Milk Protein is a premium, finely hydrolyzed peptide complex derived from pure cow's milk. This cosmetic-grade milk protein hydrolysate is produced through controlled enzymatic hydrolysis, breaking large proteins into low-molecular-weight peptides and amino acids-significantly boosting solubility, skin penetration, and bioavailability over non-hydrolyzed proteins.
Engineered for advanced cosmetic and personal care, the high-purity powder delivers essential and non-essential amino acids, the fundamental building blocks for skin and hair. It acts as a powerful humectant, film-former, and conditioning agent, providing immediate and long-term moisturization, improving elasticity, and reinforcing the skin's barrier. Every batch is rigorously tested for safety, consistency, and performance, making it an ideal active for anti-aging, moisturizing, and reparative skincare as well as premium hair care.
Processing Introduction
The production follows a strict, GMP-compliant process: Fresh, Premium Cow's Milk → Pasteurization → Separation/Casein/Whey Isolation → Enzymatic Hydrolysis (using food-grade specific proteases) → Process Control (pH, temperature, time) → Enzyme Deactivation → Filtration & Purification → Ultrafiltration (for molecular weight control) → Concentration → Spray Drying → Sieving & Blending → Quality Control & Packaging. This controlled hydrolysis is key to achieving the desired peptide profile and functional properties.

FAQ
Q: Is it safe for sensitive skin?
A: Yes. Its low molecular weight and naturally derived composition make it inherently mild and non-irritating, with demonstrated soothing properties. That said, for end-users with known hypersensitivity, we still recommend a standard patch test prior to full application-this is a prudent measure we advise across all our ingredient offerings to ensure optimal tolerability.
Q: Can it be used in clear formulations?
A: At lower use levels (1-2%), it can yield clear to slightly opalescent solutions. For crystal-clear products, testing is required as transparency depends on the full formulation matrix.
Q: What is the difference between hydrolyzed milk protein and regular milk powder?
A: Hydrolyzed milk protein is a refined, soluble peptide fraction with proven skin benefits and penetration. Regular milk powder contains lactose, fats, and undenatured proteins, which are less stable, harder to formulate, and offer lower targeted cosmetic efficacy.
Q: Is it vegan?
A: No. Hydrolyzed Milk Protein is an animal-derived ingredient sourced from cow's milk.
Q: What documentation do you provide?
A: We provide a full dossier per batch: Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), Technical Data Sheet (TDS), and origin/source documentation, plus allergen statements.
