Posted: June 27, 2007

The Cosmetic, Toiletry and Fragrance Association's (CTFA) Cosmetic Ingredient Review (CIR) panel summarized safety assessments and reviews made at its June 5, 2007 meeting.

Aminomethyl propanol and aminomethyl propanediol were deemed safe in the practices of use and concentration as described in the safety assessment.

Thioglycolates including: ammonium thioglycolate, butyl thioglycolate, calcium thioglycolate, ethanolamine thioglycolate, ethyl thioglycolate, glyceryl thioglycolate, isooctyl thioglycolate, isopropyl thioglycolate, magnesium thioglycolate, methyl thioglycolate, potassium thioglycolate, sodium thioglycolate and thioglycolic acid are considered safe for use in hair straighteners, permanent waves, tonics, dressings and other hair grooming aids, wave sets, other noncoloring hair products, and hair dyes and colors, as described in this safety assessment, at concentrations up to 15.4% (as thioglycolic acid). Hairdressers should avoid skin contact and minimize consumer skin exposure.

Calcium thioglycolate, potassium thioglycolate, sodium thioglycolate and thioglycolic acid in depilatories were determined to be safe when formulated to be nonirritating under conditions of recommended use.

According to the CIR panel, in regards to tentative amended safety assessments, interested persons are given 60 days to comment, provide information, and/or request an oral hearing. Information may be submitted without identifying the source or the trade name of the cosmetic product containing the ingredient. All unpublished data submitted to CIR will be discussed in open meetings and are available at the CIR office for review by any interested party. These ingredient reports are next scheduled for review by the CIR Expert Panel at its September 24-25, 2007 meeting.
