Sorbitan Caprylate is a nonionic surfactant and emulsifier synthesized from sorbitol (a sugar alcohol) and caprylic acid (C8 fatty acid). It stabilizes oil-water mixtures, making it vital in cosmetics (creams, lotions), pharmaceuticals (ointments), and food (as an additive, e.g., E494). Its dual hydrophilic-lipophilic properties (HLB ~4-6) enable use in both oil-in-water and water-in-oil systems. Mild and biodegradable, it enhances product texture, prevents separation, and solubilizes oils/fragrances. Regulated as safe by FDA (21 CFR) and EU cosmetics standards, it is low-irritation, suitable for sensitive skin, and found in moisturizers, sunscreens, and processed foods like baked goods.
Sorbitan Caprylate is a nonionic surfactant and emulsifier derived from sorbitol (a sugar alcohol) and caprylic acid (a medium-chain fatty acid, C8). It is widely used in cosmetics, pharmaceuticals, and food products due to its ability to stabilize mixtures of oil and water. Here’s a detailed breakdown:
Formed by esterifying sorbitol with caprylic acid (octanoic acid), resulting in a molecule with both hydrophilic (water-attracting) and lipophilic (oil-attracting) properties.
Chemical formula: Typically represented as C14H26O6 (varies slightly based on esterification degree).
Emulsifier: Stabilizes oil-in-water (O/W) or water-in-oil (W/O) emulsions, preventing separation.
Solubilizer: Helps dissolve oils, fragrances, or hydrophobic actives in water-based formulations.
Texture Enhancer: Improves the spreadability and smoothness of creams, lotions, and cosmetic products.
Skincare: Used in creams, lotions, sunscreens, and serums for even texture and stability.
Haircare: Found in conditioners or styling products to enhance softness and manageability.
Makeup: Stabilizes foundations, lipsticks, and mascaras.
Topical ointments, creams, or gels to uniformly disperse active ingredients.
Approved as a food additive (E494 in some regions) for emulsifying baked goods, confectionery, or processed foods.
Lubricants, coatings, or agrochemical formulations.
Safety: Generally recognized as safe (GRAS) for topical and limited food use. Non-irritating and suitable for sensitive skin.
Regulatory Status:
Approved by the FDA (21 CFR) for food and cosmetic use.
Listed in the EU Cosmetics Regulation (INCI name: Sorbitan Caprylate).
Complies with ISO, USP, and other pharmacopeial standards.
Mild and biodegradable.
Enhances product stability without compromising sensory qualities (e.g., lightweight feel).
Moisturizers, sunscreen lotions, medicated creams, and processed foods like whipped toppings.
In summary, Sorbitan Caprylate is a versatile, safe ingredient that improves texture and stability in formulations across industries. Always check local regulations for specific usage limits.
