JASMONYL.

Questionable CAS 1322-17-4 / PERFUMING

Jasmonyl, chemically a blend of 3-pentyl-4-tetrahydropyranyl acetate and 5-methyl-3-butyl-4-tetrahydropyranyl acetate, is a synthetic aroma compound. It is primarily valued in formulations for its distinct lactonic jasmine fragrance, often complemented by a subtle mushroom-like note, and its ability to enhance scent diffusion.

Summary

Science

Mechanism of Action

As a fragrance ingredient, Jasmonyl does not possess documented direct mechanisms of action on skin physiology for skincare benefits. Its primary function is to contribute to the olfactory profile of a product, enhancing the overall user experience.

Dusting Analysis

Commonly dusted

Jasmonyl is chemically distinct from 'jasmonate derivatives' (JADs), which have shown potential in anti-aging through mechanisms like extracellular matrix remodeling and accelerated epithelial repair. However, these specific skincare benefits are not directly attributed to Jasmonyl itself, which is strictly an aroma chemical. This misattribution represents a significant 'dusting' concern in skincare marketing.

Stability

Jasmonyl exhibits good stability in formulations with a pH range of 6.0 to 10.0, making it suitable for products like shampoos and soaps. However, its stability is significantly compromised in acidic environments, specifically at pH 2.0 (acid cleaner), 3.0 (fabric conditioner), and 3.5 (antiperspirant).

Conflicts

  • strong oxidizing agents
  • acidic pH environments (below pH 6.0)

Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) has not formally reviewed Jasmonyl. While IFRA recommends usage levels up to 8.0000% in fragrance concentrates, Material Safety Data Sheets (MSDS) classify it as a hazardous substance with acute effects including skin and eye irritation, and potential dermatitis from prolonged exposure. Conflicting information exists, as an 8% solution of 'jasmin acetate jasmonyl' has been reported to cause no irritation or sensitization in human experience.

Our Assessment

Verdict

Questionable

Jasmonyl offers no direct skincare benefits and carries a moderate risk of irritation, making its inclusion in a precision skincare regimen highly questionable given its primary role as a fragrance and the potential for 'dusting' through misidentification with active jasmonate derivatives.
