[Triethanolamine supply] The role and limit requirements of triethanolamine in cosmetics and skin care products

It is understood that triethanolamine at room temperature It is a colorless, transparent and viscous liquid with a slight ammonia smell. It is hygroscopic and can absorb moisture and carbon dioxide in the air. It can be freely mixed with water and alcohol, soluble in chloroform, and slightly soluble in benzene and ether. Triethanolamine is often used in cosmetics and skin care products. Let’s take a look at its role and usage limit requirements:

The role of triethanolamine in cosmetics and skin care products:

It is used as an emulsifier, Moisturizer, humectant, thickener, PH balancer;

Used in cosmetic formulations to neutralize with fatty acids to form soap, and to neutralize with sulfated fatty acids to form amine salts;

Triethanolamine is a commonly used emulsifier in cream preparations. Cream products emulsified with triethanolamine have the characteristics of fine paste and bright white paste;

Triethanolamine forms with higher fatty acids or higher fatty alcohols The colloidal phase has good stability, stable product quality, and can accommodate high proportions of external ingredients;

Triethanolamine is the most commonly used neutralizing agent for acidic polymer gels containing carbomer. The carboxyl groups of Pom are neutralized to form a stable polymer structure to achieve thickening and moisturizing application effects.

Usage limit requirements of triethanolamine:

Triethanolamine mainly plays a role in skin care by adjusting PH value and moisturizing. But if it is too much, it will cause damage to the skin. However, adding trace amounts of triethanolamine is safe. People with sensitive skin can do an allergy test before using skin care products containing triethanolamine to make sure they are not allergic.

The maximum allowable concentration of triethanolamine in non-leaching cosmetics is 2.5%; there is no requirement for other products;

The purity requirement of triethanolamine is ≥99.0%;

Related Component limit requirements: diethanolamine in triethanolamine ≤ 0.5%, nitrosamine in triethanolamine ≤ 50ug/kg;

It must not be used together with nitrosylation system.
