Skin Glossary

Formaldehyde is a colorless, flammable, strong smelling chemical used in many household products. It is classified as a human carcinogen by the International Agency for Research on Cancer. Its uses include preservative, pesticide, disinfectant and can also be found in glues adhesives, hair products and cosmetics.

Formaldehyde releasers are chemicals which release formaldehyde as a result of decomposition or are made from formaldehyde and contain residues of free formaldehyde. They can include Quarternium 15, DMDM Hydantoin, Imidazolidinylurea, Diazolidinylurea and sodium hydroxymethylglycinate.

Fragrances add flavor or scent to skin care, cosmetics, personal care products as well as many other products found in the home or at work. They can be derived from plants or botanicals (natural) or through chemical processes (synthetic). The most common fragrances include geraniol, cinnamaldehyde, hydroxycitronellal, isoeugenol, eugenol and oak moss. Beware, even products labelled "unscented" can contain masking fragrances.
