However, the levels of N-nitrosating ingredients in skin care products are highly regulated, so the interaction of the two ingredients to form carcinogenicⁱXAn element, ingredient, or chemical that has potential cancer-causing properties. compounds is relatively low.

Here are some benefits of using triethanolamine in cosmetics:

1. Balances The pH Levels

It is known to neutralize higher and lower pH and reduce the acidity and alkalinityⁱXThe capacity of a water body to neutralize bases and acids to obtain a balanced pH level. of any product. Products with neutral pH levels do not irritate the skin.

2. Excellent Emulsifier

Triethanolamine is also said to help in the emulsification of various ingredients, which is one of the primary reasons it is used in creams and other product formulations.

Emulsification is the process of mixing two immiscible liquids, mostly an oil and non-oil liquid, to form a more homogenous product. For this process, you need a chemical that helps in the process by holding both molecules together.

Triethanolamine can aid this process and prevent oils and other liquids from separating, giving the product an even consistency.

3. Thickening Agent

Another reason you find triethanolamine in lotions and creams is its benefit as a thickening agent (3). Many formulations (like creams, moisturizers and conditioners) require thickeners to get the ideal consistency.

Quick Tip

You can use cleansing milk-cream emulsions containing triethanolamine for removing your makeup.
