Verdict
Minimal cosmetic relevance compared to niacinamide and panthenol — included in vitamin B complex formulations primarily for completeness or synergy claims. Safe by analogy with extensive oral vitamin safety, best positioned as a minor antioxidant support ingredient in multi-vitamin or skin-energy concept formulations.
US Note
No CIR-specific safety assessment for standalone cosmetic use. Thiamine HCl is an essential vitamin with well-established oral safety. FDA-GRAS for food use. Minimal dedicated topical cosmetic research. EU imposes no specific restrictions. Use based on general vitamin safety profile.
