Propylene Glycol Dibenzoate
What is Propylene Glycol Dibenzoate?
Propylene Glycol Dibenzoate is an ester derived from propylene glycol and benzoic acid, primarily used as a solvent, plasticizer, and film-forming agent in cosmetic formulations. It helps dissolve other ingredients, improves product spreadability, and provides a non-greasy, smooth texture in skincare products like lotions, creams, and hair styling products. Its low volatility and compatibility with water-based systems make it a versatile ingredient in personal care formulations.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Plasticizer
Improves flexibility and reduces brittleness of films (e.g., nail coatings, hair sprays), helping prevent cracking and enhancing smooth application.
Humectant
Attracts and holds water in the stratum corneum, boosting hydration and plumpness; commonly used in moisturizers, cleansers, and hair conditioners.
Solvent
Dissolves and carries other ingredients, helping control viscosity, evaporation rate, and delivery of actives in both water- and oil-based systems.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
