Ceteareth-33

Ceteareths (Ceteareth-2, Ceteareth-3, Ceteareth-4, Ceteareth-5, Ceteareth-6, Ceteareth-7, Ceteareth-8, Ceteareth-9, Ceteareth-10, Ceteareth-11, Ceteareth-12, Ceteareth-13, Ceteareth-14, Ceteareth-15, Ceteareth-16, Ceteareth-17, Ceteareth-18, Ceteareth-20, Ceteareth-22, Ceteareth-23, Ceteareth-24, Ceteareth-25, Ceteareth-27, Ceteareth-28, Ceteareth-29, Ceteareth-30, Ceteareth-33, Ceteareth-34, Ceteareth-40, Ceteareth-50, Ceteareth-55, Ceteareth-60, Ceteareth-80, Ceteareth-100) are liquids to waxy solids. In cosmetics and personal care products, Ceteareth ingredients are used in skin care products, moisturizers, hair conditioners, suntan and indoor tanning products and hair dyes, colors, and tints.

The safety of the Ceteareth ingredientss has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that Ceteareth-2, -3, -4, -5, -6, -7, -8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18, -20, -22, -23, -24, -25, -27, -28, -29, -30, -33, -34, -40, -50, -55, -60, -80 and -100 were safe for use in cosmetics and personal care products. Ceteareth ingredients should not be used on damaged skin.CIR Safety Review: The CIR Expert Panel considered previous findings from the safety assessment of Polyethylene Glycol (PEG), several fatty alcohols (Cetearyl Alcohol, Cetyl Alcohol, and Stearyl Alcohol), and Steareths to supplement the data on the Ceteareth ingredients. These data indicated little evidence of toxicity. Data on the PEG ingredients indicated that when used on burn patients, PEGs may result in kidney effects. Therefore, the CIR Expert Panel also concluded that the Ceteareth ingredients should not be used on damaged skin.

Ceteareth-15 (10% in formulation) was minimally irritating after a single dermal exposure. In clinical studies, Ceteareth-15 (1.5% in formulation) produced minimal irritation when tested in both 4- and 21-day patch tests, and was not a sensitizer when tested (1.35% in formulation) in a repeat-insult patch test.

Small amounts of 1,4-dioxane, a by-product of ethoxylation, may be found in the Ceteareth ingredients. The potential presence of this material is well known and can be controlled through purification steps to remove it from the ingredients before blending into cosmetic formulations.

The Ceteareth ingredients may be used in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Directive of the European Union.
