In the development of modern cosmetic formulas, the choice of raw materials directly affects the stability, safety, and efficacy of the product. Tris base, as a commonly used buffering agent, has been widely used in the field of biochemistry and has gradually become an important functional ingredient in cosmetic formulations in recent years. Its main value is reflected in the following three aspects.

1、 PH regulation and system stability

The surface pH of healthy skin is usually maintained in the neutral range (pH around 7), which is crucial for maintaining skin barrier function and microecological balance. However, many active ingredients, such as certain enzymes or acids, are only stable and effective under specific pH conditions. In multiple allocation methods, the mixing of different raw materials often leads to pH deviation from the ideal range. The effective buffering range of Tris is pH 7.0-9.0, and it has good buffering ability in a near neutral environment. After adding it to the formula, it can effectively suppress pH fluctuations caused by the interaction of raw materials or storage processes, help maintain the system within the target pH range, ensure the stability of active ingredients, and reduce potential irritation to the skin.

2、 Improve formula compatibility

Cosmetic formulas typically contain water-soluble, oil soluble, and various functional ingredients, and compatibility issues between different polar substances may lead to precipitation, delamination, or decreased activity. The Tris molecular structure contains three hydroxymethyl groups and one amino group, which have both certain hydrophilicity and weak lipophilicity, and can promote the mutual solubility of different polar components to a certain extent. For example, in systems containing insoluble components such as salicylic acid, Tris helps to improve their solubility and long-term stability, preventing crystallization. In addition, Tris can also form weak interactions with certain volatile organic amines, reducing their volatilization rate and helping to control odors and maintain component concentrations. These characteristics enable it to serve as an auxiliary solubilizer and stabilizer in complex formulations.

3、 Carbopol neutralization and rheological regulation

Carbopol is a type of polymer thickener widely used in cosmetics, and its thickening effect depends on neutralization to an appropriate pH. Unneutralized carbopol is acidic and needs to be adjusted to neutral pH for good thickening effect. Traditional neutralizing agents such as sodium hydroxide can achieve neutralization, but they may introduce sodium ions, which may affect the product's mildness or osmotic pressure. Tris, as a weak organic base, can gradually neutralize the carboxyl group of carbomer, promote its full swelling and form a stable gel structure, while avoiding the introduction of metal ions.
