Overview
Sorbeth-30 Tetraoleate (also known as Sorbitol Polyether-30 Tetraoleate) is a hydrophilic non‑ionic surfactant belonging to the polyethoxylated sorbitol ester class. It is a tetraester formed by the reaction of sorbitol with 30 moles of ethylene oxide (polyether-30 chain) followed by esterification with oleic acid. The combination of a hydrophilic sorbitol‑polyether backbone with four lipophilic oleate groups provides excellent amphiphilic properties, making it a highly effective emulsifier.

Key Properties

• Hydrophilic non‑ionic surfactant: Suitable for a wide range of emulsion systems.

• Excellent emulsifying ability: Particularly effective against highly polar oils.

• Broad emulsification range: Effective for both polar and non‑polar oils.

• High interfacial adsorption capacity: Exhibits strong interfacial adsorption and ordered arrangement at oil/water interfaces.

• Plant‑derived and biodegradable: Environmentally friendly.

• Good compatibility: Easily integrates into complex cosmetic formulations.

Applications

• Emulsions: O/W and W/O creams, lotions, and serums.

• Cleansing products: Makeup removers, cleansing oils.

• Skin care: Moisturizers, sunscreens, and other emulsion‑based products.

• Hair care: Shampoos, conditioners, and styling products.

• Color cosmetics: Foundations, primers, and other pigment‑based formulations.

Recommended Use
Typical usage levels range from 1–5% of the formulation, depending on the desired emulsion stability and oil phase composition. For optimal performance, incorporate into the oil phase or add to the emulsion system during processing.

Safety and Handling

• Generally recognized as safe for use in cosmetics at recommended concentrations.

• Low irritation potential; well‑tolerated by skin.

• Avoid contact with strong oxidizers.

• Store in a cool, dry place, away from direct sunlight.

• Use appropriate personal protective equipment (gloves, safety goggles) when handling.

Quality Assurance
Each batch is tested for purity, HLB value, and emulsification performance to ensure consistent quality.
