Science
Mechanism of Action
Operating primarily as a humectant, 1,2-Butanediol actively binds and retains water within the stratum corneum, promoting deep hydration, softness, and improved skin elasticity. Beyond its moisturizing capabilities, it functions as a skin conditioning agent, contributing to a smoother and more refined skin surface. In formulations, it serves as an effective solvent, ensuring the uniform distribution of other ingredients and enhancing overall product efficacy. Furthermore, it aids in controlling product viscosity and has been shown to augment the antimicrobial efficacy of preservation systems.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded 1,2-Butanediol is safe for use in cosmetics. However, safety data sheets indicate a potential for skin irritation (Category 2, H315), serious eye irritation (Category 2, H319), and a low risk of allergic skin reaction (Category 1, H317). Therefore, a preliminary patch test is recommended before widespread usage. Ingestion may lead to systemic illness.
