What Is It?
Toluene is a clear liquid with an aromatic odor. In cosmetics and personal care products, the use of Toluene is limited to nail products.
Why is it used in cosmetics and personal care products?
Toluene is used as a solvent to dissolve other substances, such as resins and plasticizers, used in the formulation of nail products.
The name Toluene was derived from the older name toluol that refers to tolu balsam, an aromatic extract from the tropical American tree Myroxylon balsamum, from which it was first isolated.
The Food and Drug Administration (FDA) has reviewed the safety of Toluene and permits its use as an indirect food additive. For example, Toluene may be used as a component of adhesives and coatings, paper and paperboard, and polymers that have contact with food. The safety of Toluene has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and based concluded that Toluene was safe as a cosmetic ingredient in the present practices of use and concentration. In 2005, as part of the scheduled re-evaluation of ingredients, the CIR Expert Panel considered available new data on Toluene and reaffirmed the above conclusion.

CIR Safety Review:
Two studies with Toluene showed positive clastogenic effects but the purity of the test samples was not reported, making it difficult to assess the significance of these effects. More definitive studies were carried out and Toluene did not induce cancer in any of the eight studies evaluated. Although Toluene is a potential skin irritant, no skin irritation or sentization has been observed in cosmetic products containing up to 33% Toluene. However, the sole cosmetic use of Toluene is in products intended to be applied directly to the nail. Therefore, human skin exposure to this ingredient will be minimal under conditions of cosmetic use.
THe CIR Expert Panel noted that benzene, a carcinogen may be a possible impurity in Toluene, and they indicated that products formulated with Toluene should be benzene-free. Based on the safety data and the limited skin exposure from nail products containing Toluene, the CIR Expert Panel concluded that Tolene was safe as used.

Currently, Toluene 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.

In its opinion adopted on October 10, 2006, the European Commission’s Scientific Committe on Consumer Products (SCCP) concluded that the presence of Toluene as a solvent in nail cosmetics does not pose a risk to the health. The European Commission will eventually adapt this opinion into the Cosmetics Directive.
