Goal
Reduce or prevent unwanted fishy odor from the pudendum (external genital area).
Problem
Fishy odor caused by bacterial amine reactions, especially when alkaline bodily fluids raise skin pH, leading to trimethylamine production.
Concept Summary
A personal care formulation that maintains a prolonged acidic pH (~=3-5.5) on the skin of the pudendum using a viscous carrier and alpha-hydroxy acids, thereby inhibiting bacterial amine reactions that generate malodorous compounds.
Principles
- Acidic pH maintenance
- Sustained release of acids
- Skin-compatible formulation
- Inhibition of anaerobic bacterial activity

Mechanisms of Action
- Maintain skin surface pH below 5.5 to suppress amine-producing reactions
- Provide prolonged acidic environment via viscous carrier and high-molecular-weight alpha-hydroxy acids
- Reduce activity of anaerobic bacteria on the pudendum
Applications
- Feminine personal hygiene
- Odor reduction for external genital area
- Skin-compatible deodorant
Claimed Performance
Provides a prolonged acidic pH (~=3-5.5) on the pudendum, inhibiting bacterial amine reactions and significantly decreasing malodor.
Limitations
- No quantitative efficacy data presented
- Potential skin irritation if pH is too low
- Efficacy may vary with individual microbiome
Red Flags
- Claims of being the first product to address root cause without peer-reviewed evidence
- Lack of independent replication or clinical trial data
