Is ethanolamine safe to use in cosmetics?

Ethanolamine is generally considered safe for use in cosmetics at low concentrations. Regulatory bodies set limits on its use to minimize potential risks, particularly regarding irritation and the formation of nitrosamines.

What are nitrosamines and why are they a concern?

Nitrosamines are compounds that can form when ethanolamine reacts with certain other ingredients, particularly nitrosating agents. Some nitrosamines are known carcinogens, which is why their formation in cosmetic products is a concern and regulated.

Ethanolamine

Ethanolamine is an organic compound that functions primarily as a pH adjuster in cosmetic and personal care products. It helps to stabilize the acidity or alkalinity of a formulation, ensuring optimal performance and stability. It can also act as an emulsifying agent.

Sensitization i1 / 4

Risk of allergic contact dermatitis or immune-based reactions. Fragrance allergens, preservatives, botanicals, and some dyes may score here.

Systemic exposure i0.5 / 4

Whether it has meaningful potential to be absorbed into the body at levels that may matter biologically. Most cosmetic ingredients score low unless there is known concern or high exposure.
