CIS-3-HEXENYL BUTYRATE.

Optional CAS 16491-36-4 / PERFUMING

CIS-3-HEXENYL BUTYRATE is an ester derived from butyric acid, primarily incorporated into formulations for its fresh, green, and fruity aromatic profile. While it contributes an appealing scent, its direct efficacy as a skincare active requires specific substantiation.

Science

Structurally related to butyrate, a short-chain fatty acid, CIS-3-HEXENYL BUTYRATE theoretically links to mechanisms observed with its parent compound. Butyrate has been demonstrated to improve skin barrier function and mitigate inflammation by modulating mitochondrial metabolism, enhancing the synthesis of keratinocyte-derived long-chain and very long-chain fatty acids critical for ceramide generation. Additionally, it suppresses immune responses by inhibiting cytokines and inflammatory cell production, and through histone deacetylase (HDAC) inhibition, promotes regulatory T cell (Treg) proliferation. Butyrate further inhibits Staphylococcus aureus-aggravated dermal IL-33 expression and skin inflammation via HDAC3 inhibition. However, it is crucial to note that these demonstrated benefits pertain to butyrate itself, and direct clinical evidence for CIS-3-HEXENYL BUTYRATE's specific skincare mechanisms at effective topical concentrations is not readily available.

Stability

As an ester, CIS-3-HEXENYL BUTYRATE has a propensity to hydrolyze into its corresponding acid during storage. While specific pH stability data for this compound is not available, a related isomer, cis-3-Hexenyl Isobutyrate, exhibits particular instability in shower gel and shampoo bases. It maintains stability at normal ambient temperatures and under recommended storage conditions, though heat, sparks, open flames, and temperatures exceeding its flash point should be avoided. It is prone to oxidation, and the inclusion of trace amounts of alpha tocopherol (0.1%) may prevent this degradation.

The safety of Cis-3-hexenyl butyrate has been thoroughly assessed by the Research Institute for Fragrance Materials (RIFM), with a peer-reviewed safety assessment published. RIFM identified a potential for skin sensitization in a small fraction of individuals. Consequently, the International Fragrance Association (IFRA) has established safe use standards. Maximum acceptable concentrations in finished products vary by product type; for instance, for rinse-off products with body and hand exposure, the maximum acceptable concentration is 0.84%. In alcoholic perfumes, typical usage can range from 0.080% to 8.000%. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) evaluated it as a flavoring agent in 1997, concluding no safety concern at typical intake levels, and it is listed by the FDA as a flavoring agent or adjuvant.

Our Assessment

Optional

Primarily a perfuming agent, CIS-3-HEXENYL BUTYRATE can enhance product appeal but lacks direct clinical data to substantiate the skincare benefits theoretically linked to its parent compound, butyrate, and carries a moderate sensitization risk for some individuals.
