Butylene glycol is a small diol commonly used in skincare as a humectant, solvent, and viscosity-reducing agent that helps dissolve other ingredients and improve skin feel. It is widely regarded as safe and non-sensitizing for the majority of users at cosmetic concentrations.
Caprylyl glycol is a multifunctional emollient and humectant derived from caprylic acid that helps hydrate skin and enhance the efficacy of preservatives in formulations. It is widely used as a stabilizing and conditioning base ingredient rather than a therapeutic active.
