Sorbeth-30 Tetraoleate
PEG-30 Sorbitan Tetraoleate
I. Basic Information
Sorbeth-30 Tetraoleate
CAS No.: 63089-86-1
Product Category: Organic raw material, non-ionic surfactant
Appearance: Light yellow to yellow liquid
HLB Value: ~10
pH Value: 5–7
Solubility: Soluble in water; compatible with plant oils and ester-based polar lipids
II. Physical & Chemical Properties
Surface Activity: As a non-ionic surfactant, it contains both hydrophilic and lipophilic groups, effectively reducing interfacial tension between oil and water for stable emulsification;
Emulsifying Capacity: Forms stable emulsions with small amounts of oils and fats, effective for both polar (e.g., rapeseed oil) and non-polar lipids, suitable for oil-in-water (O/W) systems;
Solubilizing Performance: Enhances solubility of plant oils, synthetic esters, fragrances, and essential oils, improving formulation clarity and stability;
Biodegradability: Derived from plant-based raw materials, exhibits excellent biodegradability, making it environmentally friendly;
Mildness: Low skin irritation, rarely causes sensitization, safe for use in products designed for sensitive skin.
III. Production Methods
Conventional Synthesis: Start with sorbitol, undergo ethoxylation with ethylene oxide to form a polyether-30 chain, followed by esterification with oleic acid under catalysis. Final product is purified via vacuum distillation and decolorization;
Green Manufacturing Process: Use of organotin catalysts for esterification shortens reaction time, allows catalyst reuse, yields lighter-colored and higher-quality product, eliminates neutralization, alkali washing, and water rinsing steps, and produces zero wastewater discharge, offering both cost and environmental benefits;
Scaled-up Industrial Route: In Malaysia, manufacturers leverage the common fatty alcohol process—transesterification of oils followed by hydrogenation and fractionation—to extend production to this class of ester-based surfactants, enabling renewable sourcing and large-scale outputbased on user-provided fat alcohol logic.
IV. Applications
Core Ingredient in Cosmetics
Emulsifier: Used in creams, moisturizers, and lotions to stabilize oil-water systems, prevent phase separation, and enhance sensory experience;
Active Cleansing Agent in Makeup Removers: Highly effective at dissolving makeup (especially heavy or waterproof cosmetics), rapidly emulsifies upon contact with water, rinses cleanly without greasy residue—key component in cleansing oils and balms;
Moisturizing & Solubilizing Agent: Offers mild hydration and dissolves oils and fragrances, ideal for skincare-focused cleansers;
Industrial & Pharmaceutical Uses
Reaction Emulsifier: Applied in O/W chemical reactions to promote uniform mixing of polar and non-polar reactants;
Drug Delivery Carrier: Functions as an emulsifier and solubilizer in pharmaceutical formulations, especially in transdermal delivery systems, enhancing drug stability and absorption efficiency;
Other Applications
Suitable for shampoos, body washes, and hair conditioners, providing gentle cleansing and emulsification while minimizing skin lipid stripping.
V. Application Cases
40610101 Sensitive Skin-Compatible Cleansing Oil
Core Formula: Dual continuous-phase system composed of isohexadecane and cetyl ethylhexanoate, combined with Sorbeth-30 Tetraoleate to achieve 3-second emulsification upon water contact, eliminating greasiness common in traditional cleansing oils;
Performance: Makeup removal efficiency exceeds 99.5%, residue rate as low as 0.03% (meets EU standards). Clinical testing on 2,000 subjects showed 32% increase in skin hydration and 40% reduction in redness area after 28 days of use;
Target Users: Safe for dry and sensitive skin types, suitable for eye and lip areas.
40610201 Oil-in-Water Moisturizing Cream
Formulation Role: Primary emulsifier stabilizing plant oils (e.g., jojoba seed oil, sunflower seed oil) with aqueous phase, improving texture smoothness and spreadability, while solubilizing natural fragrances for a fresh scent;
Product Advantages: Lightweight, non-greasy texture with fast absorption. Proven to provide over 8 hours of hydration and improve dry, rough skinbased on general cosmetic efficacy logic].
40610301 Pharmaceutical-Grade Transdermal Ointment
Material Requirement: Uses >99% purity cosmetic-grade raw material to ensure no irritant impurities;
Application Value: Acts as emulsifier and drug carrier, enabling uniform dispersion of lipophilic active ingredients and enhancing transdermal absorption. Suitable for topical treatments of chronic dermatitis, joint pain, etc.
