Product description

Arginine is a natural essential amino acid essential for protein synthesis in the human body.

It is mainly used as a nutritional supplement, but it is also used in the cosmetic industry, but not for its effects on hair and skin. As a cosmetic raw material, it is used in low concentrations mainly to raise the pH of cosmetic products.

L-arginine has an alkaline pH (a 10% solution has a pH of 1.5-12) and is much easier to work with than sodium hydroxide, which is usually used for this purpose, or baking soda. When making natural cosmetics, and especially when using natural ingredients, it is important to remember that many of them are sensitive to pH ranges and changes and lose their effectiveness at unwanted levels. This is particularly the case with natural preservatives but also with certain emulsifiers. Conversely, some natural ingredients lower the pH of the product (for example, the preservative Euxyl K903) and if it needs to be raised back to pH 5.3-5.5 an alkaline solution should be used.

When working with the cationic surfactant EMULSENSE HC, arginine is the only ingredient that is compatible with it in raising the pH of your conditioner.

To raise the pH of your cosmetic products, prepare a 10% solution of arginine in distilled water and add dropwise to the product whose pH needs to be raised. If you will also be adding a pH sensitive substance to the product, adjust the pH of the product to the desired value before adding it.

Solubility: slightly, insoluble in ethanol.

All raw materials supplied are cosmetic grade, not suitable for internal use. Use appropriate protective equipment when handling.
