1,2 Octanediol is a humectant that can boost or aid the preservation of cosmetic formulations. It can be used in combination with different ingredients to achieve self-preserving formulations, creating a biostatic environment that prevents growth of microorganisms. It is primarily effective against bacteria and can be combined with a yeast and mold control agent for broad spectrum protection. Melts at approximately 30°C to 35°C and contributes a smooth, dry sensory characteristic to skincare products. It is a multi-functional emollient, moisturizer, and wetting agent which can be used in cosmetic emulsion systems such as skin care creams and lotions or in surfactant-based products such as shower gels, facial cleansers, and shampoos.

It is recommended that 1,2 Octanediol be used at concentrations between 0.5% - 5%. When used in emulsions, it is recommended that it be incorporated into the water phase. It is also soluble in oils and may be used in anhydrous formulas.
