Background information on use in cosmetics

Yellow dye, azo dye Colourants ensure an appealing appearance of the cosmetic product and serve for the embellishment of the skin and hair. The most frequently used colourants are synthetic; only a few natural substances are available. For colourants, the applicable INCI names are in most cases the so-called Colour Index Numbers, the "CI Numbers". Fragrances or mixtures of fragrances are often referred to in the cosmetics area as "perfuming agents" or "perfume oils" or "parfum oils". On the cosmetic products they are declared with the INCI name "PARFUM". These are undiluted individual substances or their mixtures which originate from natural raw materials or can be produced (semi-) synthetically. They are starting materials for the production of perfume, eau de parfum, eau de toilette, eau de cologne and other perfumed cosmetic products. The average content of fragrances amounts in perfume to 15-30 %, in eau de parfum to 10-14 %, in eau de toilette to 6-9 %, in eau de cologne to 3-5 % as well as in skin creams, shampoos, hair and deodorant sprays to approximately 0.2-1 % and approximately 1-3 in deodorant sticks. The perfume oils include essential oils, resinoids and absolutes. The sources are, amongst others, flowers, leaves and stems, fruits and fruit peels or roots of plants; woods, grasses or herbs, needles, resins and balsams. Moreover, only compounds isolated from natural products such as aldehydes, ketones, esters, alcohols etc. are used (geraniol, citronellal, citral, eugenol, menthol) as well as semi-synthetic (citronellol, geranyl acetate, jonone) and synthetic scents (eg phenylethyl alcohol and linalool) are used. Scents of animal origin such as musk and ambra are only rarely used.

Information on safe use

This colourant is not used in products which are applied on or in the immediate vicinity of mucous membranes (eg in the lip and eye area). According to the EC Cosmetics Regulation [Regulation (EC) No. 1223/2009], which applies to the entire EU market, colourants are defined as substances which are exclusively or mainly intended to colour the cosmetic product, the body as a whole or certain parts thereof, by absorption or reflection of physical light. Annex IV of the Regulation defines the substances which may be used as colourants in cosmetic products. In this positive list of colourants maximum concentrations are defined in part for the use of these substances in cosmetic products as well as the permitted areas of application. Hair colourants are currently still separately regulated in the EC Cosmetics legislation. In future it is planned to include them also into Annex IV. Colourants are examined prior to their authorisation in Annex IV selectively for their toxicological safety and subjected to extensive tests. The manufacturers must prove the health safety in extensive scientific studies. Moreover, the approved colorants are reassessed and the list is updated accordingly in line with new scientific findings and in the event of suspected adverse events evident from market surveillance.
