PPG-12
What is PPG-12?
PPG-12, or poly(propylene glycol)-12, is a synthetic polymer made by linking propylene glycol monomers, resulting in an average of 12 units for a molecular weight around 600-900 Da. This colorless, low-viscosity liquid is commonly incorporated into skincare formulations such as lotions, creams, and serums. It works primarily as a humectant by attracting water to the skin's surface, promoting hydration retention. As a skin conditioning agent, it softens and smooths the skin by forming a light, non-occlusive film. It also serves as a solvent to blend other ingredients and improves product texture for better spreadability and absorption. Valued for its lightweight, non-greasy properties, PPG-12 enhances the sensory experience of leave-on and rinse-off products without residue.
