TRIMETHYLBENZENEPROPANOL.

Avoid CAS 103694-68-4 / FRAGRANCE, PERFUMING

TRIMETHYLBENZENEPROPANOL is a synthetic aromatic compound primarily utilized in cosmetic formulations for its characteristic floral scent, often evoking lily-of-the-valley. While providing an olfactive experience, it offers no direct skin benefits and is recognized for its potential to induce skin sensitization.

Perfuming Masking

Science

This ingredient functions solely as a perfuming agent, imparting a specific floral aroma to products through its volatile chemical structure. It does not possess any known mechanism of action that confers direct benefits to skin physiology. However, TRIMETHYLBENZENEPROPANOL has been classified as a weak skin sensitizer, exhibiting positive results in in vitro assays such as KeratinoSens, h-CLAT, and U-Sens, suggesting its capacity to potentially trigger immune responses upon dermal exposure.

Transparency

Not commonly dusted

As an ingredient with no skin benefits and a recognized sensitization risk, TRIMETHYLBENZENEPROPANOL is subject to strict regulatory limits for its inclusion. Therefore, its use is carefully controlled and not an ingredient for which 'dusting' would be applicable or safe.

Stability

As an aromatic compound, TRIMETHYLBENZENEPROPANOL is chromophorous and may undergo discoloration over time, particularly when exposed to alkaline environments. Adherence to International Fragrance Association (IFRA) Standards and other regulatory limits is critical during formulation due to its classification as a fragrance allergen.

Sensitization risk Moderate

TRIMETHYLBENZENEPROPANOL is a regulated allergen in Europe, falling under Annex III of the EC Cosmetics Regulation following assessment by the Scientific Committee on Consumer Safety (SCCS). The Research Institute for Fragrance Materials (RIFM) has conducted a safety assessment, confirming its status as a weak skin sensitizer. The International Fragrance Association (IFRA) Standards impose strict maximum concentration limits to mitigate dermal sensitization risk, varying by product type. For instance, acceptable concentrations include 0.034% in lip products, 0.15% in axillae products, 0.021% in face/body products applied with fingertips, and up to 1.3% in fine fragrances. In California, reporting is mandated for concentrations at or above 0.01% in rinse-off products and 0.001% in leave-on products. The FDA does not have specific cosmetic ingredient statuses for fragrance components unless classified as drugs.

Our Assessment

Avoid

Given its classification as a weak skin sensitizer, lack of inherent skin benefits, and strict regulatory restrictions, TRIMETHYLBENZENEPROPANOL is an ingredient Moumoujus would avoid in precision skincare formulations.
