3,3,5-trimethylcyclohexanone

3,3,5-Trimethylcyclohexanone (CAS 873-94-9) is a cyclic ketone used in fragrance formulation and as a specialty solvent in personal care applications. Isophorone is its structurally related industrial counterpart. This compound occupies a distinct niche as a fragrance ingredient with a characteristic woody, camphoraceous odor profile. It functions both as a scent contributor and as a carrier solvent in finished formulations.

In fragrance compounding, it serves as a building block for woody and fresh accords, particularly in fine fragrance and functional fragrance applications such as detergents and fabric care products. Personal care formulators incorporate it into rinse-off and leave-on products where controlled odor release is required. Its solvent properties support the dissolution of fragrance concentrates.

The material is also used for resinous materials in cosmetic bases. It is also evaluated as a flavoring agent in contexts governed by FEMA-recognized ingredient lists for various applications. 3,3,5-Trimethylcyclohexanone is supplied as a clear liquid in standard drum and intermediate bulk container quantities. Fragrance-grade material is the primary commercial specification for the industry.

Purity levels are typically at 98% or above for standard batches. Smaller pack sizes are available to support laboratory evaluation and pilot-scale formulation work for research and development teams.
