Science
Mechanism of Action
This ingredient acts as a precursor to citral, undergoing gradual hydrolysis to release a refreshing lemon aroma over time. On a biochemical level, it inhibits leucine dehydrogenase (LDH), a bacterial enzyme produced by species such as Bacillus. By blocking this enzyme, it prevents the metabolic conversion of leucine into isovaleric acid, thereby suppressing the formation of pungent body odor at its source.
Research
Clinical Evidence
Medium confidence0.5%
Key findings
- 01 In vivo testing at 0.1% concentration demonstrated a measurable reduction in isovaleric acid strength on the skin.
- 02 Formulations containing 0.1-10% weight demonstrate effective regulation of unpleasant body odors and sustained fragrance delivery.
- 03 Optimal aromatic and deodorizing performance is consistently observed in the 0.5-5% concentration range.

Dusting Analysis
While often used as a simple fragrance component, its functional odor-suppression benefits require a minimum threshold of 0.1%. Percentages below 0.05% likely serve only as a brief olfactory masking agent rather than a functional enzyme inhibitor.
The Formula
Formulation
Stability
Highly stable in alkaline conditions. As an acetal, it is susceptible to rapid hydrolysis and degradation in acidic environments (pH < 7.0).
Conflicts

Safety
Safety Profile
Low acute toxicity (LD50 > 5000 mg/kg). While its parent compound Citral is a known sensitizer, studies on related citral acetals at 4% show no irritation or sensitization in human subjects. Industry standards recommend a maximum of 5% in fragrance concentrates.
