Common Ingredients
Castor oil and its derivatives are found in many cosmetics as it is "non-comedogenic" (does not exacerbate or contribute to acne).
Cerebrosides (cells from the nervous systems of cattle or swine) were once used in some high-end skin-care products to increase moisture retention and to create a smooth skin surface, however the BSE controversy has put an end to this practice.
In many countries colors in cosmetics are listed as numbers from the Colour Index International. The scheme covers colors used in food, personal care products, cosmetics, household products and fabric dyeing. So, for example you will not normally see tartrazine listed in lipstick ingredients, but it may be there listed as C.I. 19140. Erythrosine will be listed as C.I. 45430, and so on. In US and Canada colors are listed as FD & C colors. Tartrazine (E012) is FD & C Yellow 5 and erythrosine (E127) is FD & C Red 3.

Famous quotes containing the words common and/or ingredients:
“Unpretending mediocrity is good, and genius is glorious; but a weak flavor of genius in an essentially common person is detestable. It spoils the grand neutrality of a commonplace character, as the rinsings of an unwashed wine-glass spoil a draught of fair water.”
—Oliver Wendell Holmes, Sr. (1809–1894)
“In all cultures, the family imprints its members with selfhood. Human experience of identity has two elements; a sense of belonging and a sense of being separate. The laboratory in which these ingredients are mixed and dispensed is the family, the matrix of identity.”
—Salvador Minuchin (20th century)
