L-Arginine

L-arginine is a water-soluble amino acid that is used in cosmetic and technical formulations mainly as an auxiliary functional ingredient , humectant and pH regulator. It is a basic amino acid naturally present in the proteins of living organisms; in industrial production it is usually obtained by fermentation of carbohydrate raw materials using selected microorganisms, then it is purified, crystallised, dried and processed into a fine powder. In cosmetic manufacturing, L-arginine is valued especially for its ability to increase the pH of acidic formulas , support the comfort of aqueous formulations and complement the amino acid profile of products intended for the care of the skin, hair and scalp. Key benefits Water-soluble amino acid suitable for the water phase of cosmetic formulations. Regulates pH – used mainly to gently increase pH in acidic formulas. Humectant ingredient that supports water binding in the superficial layers of the skin. Supports skin comfort in products intended for hydration, regeneration and after-cleansing care. Suitable for hair care products , especially shampoos, conditioners, hair tonics and scalp care products. Good compatibility with aqueous systems , hydrolats, gels, emulsions and mild surfactant-based formulas. Auxiliary ingredient in acid-based cosmetics , where it can be used to adjust pH in formulations with AHA, PHA or other acidic active substances. Practical raw material for formulators who need to work with pH more precisely and gently than when using strong alkalis. Suitable for products such as hydrating serums and facial gels, fa
