1,3 propylene glycol (propylene glycol) is a natural green alternative to propylene glycol derived from corn sugar. It is used as a moisturizer, hair and skin conditioner, preservative and solvent. It has a light, non-sticky, slightly dry skin feeling.Propylene glycol increases hydration when used in hair and body products, and at 5%, propylene glycol outperforms propylene glycol and butanediol. When combined with glycerol, propylene glycol shows a synergistic effect that can reduce the viscosity of glycerol while providing the benefit of increased hydration levels. At levels up to 75%, it shows a small likelihood of irritating or sensitizing the skin. In surfactant systems, propylene glycol increases the transparency and viscosity of the surfactant system while reducing the amount of salt required to thicken the product. It improves the glitter foam and produces a more elegant system with more delicate foam and more dense foam.In hair care products such as shampoos,…
