Hypoallergenic

Hypoallergenic, meaning "below normal" or "slightly" allergenic, was a term first used in a cosmetics campaign in 1953. It is used to describe items (especially cosmetics and textiles) that cause or are claimed to cause fewer allergic reactions. Hypoallergenic pets still produce allergens, but because of their coat type, absence of fur, or absence of a gene that produces a certain protein, they typically produce fewer allergens than others of the same species. People with severe allergies and asthma may still be affected by a hypoallergenic pet.

Note that the term lacks a medical definition, but it is in common usage and found in most standard English dictionaries. In some countries, there are allergy interest groups that provide manufacturers with a certification procedure including tests that ensure a product is unlikely to cause an allergic reaction, but such products are usually described and labeled using other but similar terms. So far, public authorities in no country provide an official certification that an item must undergo before being described as hypoallergenic. The cosmetic industry has been trying for years to establish an industry standard for use of the term.
