Propanediol is a versatile, colorless, odorless liquid used in cosmetics, personal care, and pharmaceuticals. It's valued for its humectant, solvent, and emollient properties and is often used as a safer alternative to propylene glycol.
The boiling point of propanediol is approximately 188°C (370°F). Its high boiling point makes it stable in a wide range of industrial and personal care applications, including skincare and deodorants.
Propanediol is included in deodorants as a natural, skin-friendly alternative to traditional glycols. It helps dissolve active ingredients, improves glide, and retains moisture without irritating sensitive skin.
The chemical formula of propanediol is C3H8O2. It consists of three carbon atoms, eight hydrogen atoms, and two hydroxyl groups, giving it excellent moisture-retaining and solvent properties.
Yes, propanediol is generally recognized as safe (GRAS) for topical use. It is non-irritating, non-sensitizing, and suitable for use in products designed for sensitive or allergy-prone skin.
