Product Description
Glyceryl Caprylate is a 100% plant-derived multifunctional cosmetic ingredient. With a high content of glyceryl monoester (≥88%), its short-chain structure can penetrate the skin and interact with water molecules, helping to retain moisture and enhance skin hydration.
Its amphiphilic properties reduce surface tension, contributing to smaller droplet sizes in oil-in-water (O/W) emulsions and thereby improving emulsion stability. It is mainly used in cosmetics as a co-emulsifier, emollient, and moisturizing agent, enhancing the sensory performance of finished products.
In addition, Glyceryl Caprylate is a novel, highly effective broad-spectrum preservative. It exhibits inhibitory activity against Gram-positive and Gram-negative bacteria, molds, and yeasts. Compared with traditional preservatives, Glyceryl Caprylate is milder and less irritating to the skin, aligning with modern consumer demand for gentle and skin-friendly cosmetic formulations.
In color cosmetics and powder formulations, Glyceryl Caprylate coats individual powder particles and functions as a binder and wetting agent, resulting in a more uniform appearance. This ingredient is suitable for a wide range of formulation systems, including oil-in-water (O/W) and water-in-oil (W/O) emulsions, anhydrous formulations (such as solid or color cosmetic products), and surfactant-based systems.

Product Functions & Applications
1. Moisturizing Agent
Moisturization is one of the fundamental functions of cosmetic products. Glyceryl Caprylate provides effective moisturizing benefits, leaving the skin smooth and radiant. Its short ester carbon chain penetrates the skin and associates with skin lipids, while its hydrophilic groups help retain moisture in the stratum corneum. The hydroxyl groups form hydrogen bonds with water molecules, locking in moisture and providing long-lasting hydration, thereby helping to prevent skin dryness.
2. Emulsifier
Glyceryl Caprylate forms an interfacial film at the oil–water interface, effectively stabilizing emulsions and preventing phase separation.
3. Emollient / Refatting Agent
Its refatting properties make Glyceryl Caprylate an ideal ingredient for improving skin texture, delivering and retaining lipid components on the skin surface, resulting in softer and more supple skin with enhanced gloss.
4. Antimicrobial & Preservative Function
In addition to its emulsifying, moisturizing, and emollient properties, Glyceryl Caprylate exhibits antimicrobial activity. Its main mechanisms include:
Cell membrane disruption: Interaction with membrane lipids increases membrane fluidity and compromises membrane integrity.
