[Antiperspirants and deodorants--ingredients and evaluation]

Area of Science:

• Cosmetic Science
• Dermatology

Background:

• Antiperspirants and deodorants are increasingly popular cosmetic products.
• Common antiperspirant active ingredients include aluminum chlorohydrate and aluminum zirconium tetrachlorohydrate glycine complex.
• Deodorant actives often involve perfumes, antimicrobial agents like triclosan, odor-binding substances (e.g., zinc ricinoleate), or pH modifiers (e.g., triethyl citrate).

Purpose of the Study:

• To review the active ingredients and evaluation methods for antiperspirants and deodorants.
• To highlight the importance of safety and efficacy in product development.

Main Methods:

• Review of commonly used active ingredients in antiperspirants and deodorants.
• Discussion of methods for evaluating product efficacy, including olfactory tests and assessment of effects on cutaneous microflora.

Main Results:

• Aluminum chlorohydrate and aluminum zirconium tetrachlorohydrate glycine complex are primary antiperspirant actives.
• Triclosan, zinc ricinoleate, and triethyl citrate are examples of deodorant ingredients with various functions.
• Efficacy assessment relies on sensory evaluations and microbiological analysis.

Conclusions:

• The cosmetic industry prioritizes safety and efficacy for antiperspirants and deodorants.
• Olfactory tests and microflora analysis are key methods for establishing product effectiveness.
