Description

Propyleneglycoldioctanoate is a synthetic ester derived from propylene glycol and caprylic (octanoic) acid, functioning as a versatile emollient and solvent. This compound is valued for its excellent skin feel, low viscosity, and ability to solubilize active ingredients, making it a key component in high-performance formulations. It is primarily needed by manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking stable, non-greasy, and high-purity ingredients.

Application

• As a premium emollient and skin-conditioning agent in lotions, creams, and sun care products.
• As a solubilizer and carrier for active pharmaceutical ingredients (APIs) in topical drug delivery systems.
• As a plasticizer and lubricant in polymer and resin applications.
• As a base fluid and additive in specialty lubricants and functional fluids.
• As a cosmetic-grade solvent in makeup, lipsticks, and color cosmetics for enhanced pigment dispersion.
• As a texturizer and spreading agent in hair care and styling products.
