Amidoamine (Stearamidopropyl Dimethylamine) Ingredient Allergy Safety Information

What is it?

Briefly: Amidoamine is a chemical found in many cosmetics and personal care products. SkinSAFE should help you avoid most

products that contain it.

In Detail: Amidoamine is a manufacturing by-product of the soap-like chemical, cocamidopropyl betaine.

How can I avoid it?

Since cocamidopropyl betaine is widely used, its chemical by-product, amidoamine, may be difficult to avoid. It is found in many

personal care products. It is primarily found in shampoos and bath gels, but is also used in some bar soaps, liquid detergents, surface

cleaners, pet care products, and other skin and hair care products. Allergy to amidoamine typically presents as eyelid, facial, scalp

and/or neck dermatitis.

As they are chemicals that are so closely related, it is important to avoid both amidoamine and its derivitive, cocamidopropyl betaine.

Skin contact with amidoamine is required for it to cause a rash. Discontinuation of exposure to products containing amidoamine

should result in improvement and/or resolution of your dermatitis. By law, all products made in the U.S. for topical use have the

ingredients listed either on the product package or the box that contains it, so check the labeling of your skincare products for this

ingredient. If there is not enough information, ask your pharmacist or retailer, or contact the company directly. At work, request a

Safety Data Sheet (SDS) to help identify potential sources of exposure.
