The ingredient narratives reshaping clean beauty.
Alcohol Denat.
aka denatured alcohol · ethanol denatured · SD alcohol
Standard vehicle and antimicrobial in fragrance formulations with mature safety record. Remains controversial in clean-beauty despite evidence.
- Solubilises fragrance and lipophilic actives
- Antimicrobial
- Creates lightweight fast-absorbing textures
- Astringent — temporary pore-tightening
- Enhances percutaneous absorption of co-actives
- Fine fragrance carrier
- Astringent toners
- Hair sprays
- Micellar waters
- Skin prep formulations
At >30% disrupts stratum corneum lipid organisation and elevates TEWL. At fragrance-level concentrations barrier disruption is transient in intact skin.
Chronic high-concentration application has documented barrier-disruptive effects. Rosacea and atopic dermatitis individuals should avoid high-alcohol formulations.
Frequently banned in clean lists despite mature safety data. Discourse conflates high-concentration barrier disruption with routine use.
