About QUATERNIUM-24

An antimicrobial or preservative that helps keep products stable, but it needs more caution than simple moisturizers.

Detailed Analysis

QUATERNIUM-24 is used to limit microbial growth or deliver antimicrobial performance in a formula. This category is effective at low levels but deserves more caution because irritation, sensitization, or systemic-toxicity concerns matter more than they do for basic moisturizers and emollients. Available hazard data include H302, H314, H400, so concentrated raw-material exposure can look harsher than finished-product use.
