Formaldehyde Releasers. What are they?

What is a Formaldehyde Releaser?

A formaldehyde-releaser is a chemical compound that slowly releases formaldehyde as it decomposes in a product formulation. Formaldehyde-releasers are used as an antimicrobial/antifungal preservative in cosmetics and hair care products. Like formaldehyde, formaldehyde-releasing preservatives are also known allergens and sensitizers. The seven most commonly used formaldehyde-releasers to avoid are:

DMDM hydantoin
Imidazolidinyl urea
Diazolidinyl urea
Quaternium-15
Bronopol
5-Bromo-5-nitro-1,3-dioxane
Sodium hydroxymethylglycinate

 

2015 Allergen of the Year

Formaldehyde is a known carcinogen (can be cancer causing) and has been named the ‘2015 Allergen of the Year’ by the American Contact Dermatitis Society. It has been shown that formaldehyde may have dangerous health effects to the human body even at low levels of exposure. Because of these concerns, most manufacturers have pulled it from their product formulations.  Still, consumers demand affordable products with a prolonged shelf life. Manufacturers use substitute preservatives such as formaldehyde-releasers because they are economical and readily available. They act like a time-released preservative as the product sits on a store or bathroom shelf. They are also known to be irritating to sensitive skin.

Using a single product with a formaldehyde-releasing preservative may not be a big health risk, but that product might not be the only source of exposure.  Many products that we use on a daily basis contain these ingredients.

 

Read the Ingredient Label
