Comprehensive Introduction
1,2-Pentanediol CAS 5343-92-0 is a sustainable, high-performance ingredient, functioning as a premium humectant, preservative booster, and solvent enhancement carriers. Sourced entirely from non-food biomass corncob, it exemplifies green sustainable cosmetic science. Produced via a patented manufacturing process, it achieves ≥99.5% cosmetic-grade purity while significantly reducing carbon footprint.
This multifunctional active offers three key benefits: a. Deep hydration with enhanced moisturization and a non-sticky sensory profile, outperforming glycerin. b. Natural preservation efficacy, enabling reduction in phenoxyethanol. c. Balanced solubility and stability, compatible with serums, emulsions, and active ingredient encapsulation systems.
Free from petrochemical residues and heavy metals, US BETA Analytic Bio-based Testing Report 98%, underscoring its alignment with the principles of the circular bio-economy. Our product is particularly suitable for applications such as sensitive skin serums, baby care products and high protection sunscreens, and it has passed the human skin cumulative irritation test (HRIPT). It is gentle and non-irritating and is ideally suited for demanding formulations under the 'Clean Beauty' concept. Our products have achieved a number of ESG compliant certifications such as REACH, COSMOS, HALAL and KOSHER Organic, which have accelerated market acceptance of our products and helped position them in a premium market.
