Tromethamine
Tromethamine (also known as Tris or THAM) is a synthetic organic compound with an alkaline pH used in cosmetic formulations as a buffering agent. It works by neutralising acidic ingredients and stabilising the pH of a product to ensure it remains within the optimal range for skin compatibility and ingredient efficacy. It also serves a masking function, reducing the perceptible odour of certain raw materials.

Sodium citrate (trisodium citrate) is a salt of citric acid used primarily as a pH buffering agent and chelating agent in cosmetic formulations. It adjusts and stabilises the pH of products while also neutralising metal ions that can destabilise formulas. It is a widely used helper ingredient across skincare, haircare, and cleansing products.
Learn more →Disodium Phosphate
Disodium Phosphate (disodium hydrogen orthophosphate) is an inorganic salt used in cosmetics primarily as a pH buffering agent. It is commonly paired with sodium phosphate (monosodium phosphate) to create a phosphate buffer system that maintains stable pH in formulations. It also has anticorrosive and masking properties.

Sodium Phosphate (sodium dihydrogen orthophosphate) is an inorganic salt used in cosmetics primarily as a pH buffering agent. It helps maintain a stable pH in formulations, ensuring that active ingredients remain effective and that the product stays within a safe pH range for skin contact. It is a technical ingredient that does not provide direct skin benefits.
