PEG-30 Dipolyhydroxystearate: English Applications

1. Cosmetics & Personal Care

• Emulsifier in Advanced Formulations

• Used in high-end skincare (e.g., serums, anti-aging creams, sunscreen lotions) to create stable O/W emulsions with low viscosity, ensuring elegant textures that absorb quickly into the skin.

• Ideal for oil-soluble actives (e.g., vitamins, plant extracts) by solubilizing them in water-based systems, enabling clear or translucent formulations (e.g., micellar waters, emulsified oils).

• Sunscreen Formulations

• Enhances the dispersion of UV filters (e.g., octinoxate, avobenzone) in aqueous sunscreens, improving efficacy and reducing white cast.

• Stabilizes nanoemulsions for transparent or sprayable sunscreens.

• Hair Care Products

• Added to leave-in conditioners, styling creams, and hair serums to emulsify silicones or oils, providing anti-frizz benefits and improved slip for easy application.

• Color Cosmetics

• Used in liquid foundations, BB creams, and mascaras to disperse pigments evenly, prevent settling, and improve spreadability.

2. Pharmaceuticals

• Solubilizer for Oral/Liquid Medications

• Enhances the solubility of poorly water-soluble drugs (e.g., lipophilic APIs) in oral suspensions, syrups, or injectable emulsions (e.g., lipid-based drug delivery systems).

• Emulsifier in Topical Preparations

• Formulates stable emulsions for creams, lotions, or ointments, ensuring uniform distribution of active ingredients (e.g., corticosteroids, antifungals).

• Parenteral Formulations

• Occasionally used in microemulsions for intravenous delivery, though typically limited by PEG’s potential immunogenicity (e.g., in niche lipid-based formulations).

3. Food & Beverage (Limited Applications)

• Emulsifier in Specialty Products

• Approved in some regions for specific food uses (e.g., solubilizing flavors or vitamins in low-fat beverages, dairy alternatives, or nutritional supplements), though less common than glycerol-based emulsifiers due to regulatory restrictions in certain markets.

4. Industrial & Technical Applications

• Lubricants and Metalworking Fluids

• Acts as a dispersant or emulsifier in water-based metalworking fluids, improving the stability of oil droplets and enhancing cooling/lubrication during machining.

• Paints, Coatings, and Inks

• Stabilizes pigment dispersions in water-based paints and inks, preventing agglomeration and improving color uniformity.

• Polymer Processing Aids

• Used as a surfactant in emulsion polymerization (e.g., producing latex particles) to stabilize monomer droplets and control particle size.

5. Agriculture & Biotechnology

• Pesticide Formulations

• Emulsifies oil-based pesticides into water-dilutable concentrates, improving sprayability and uniform crop coverage.

• Biotech and Cell Culture

• In niche applications, may stabilize lipid-based carriers for gene/drug delivery in research settings (e.g., liposome formulations).

Key Properties & Considerations

• Chemical Structure: HO-(CH₂CH₂O)₃₀-OOC-(CH₂)ₙ-CH(OH)-CH₂(OH) (n ≈ 14–16, derived from polyhydroxystearic acid).

• HHLB Range: High hydrophilicity (HHLB ~15–18), suitable for O/W emulsions and solubilizing oil in water.

• Solubility: Soluble in water, ethanol, and glycols; dispersible in oils.

• Regulatory Status:

• Cosmetics: Approved by EC Regulation 1223/2009 (EU), CIR (USA), and Japan Cosmetic Standards.

• Food: Limited approval (e.g., FDA lists PEG esters as GRAS for specific uses; check regional regulations).

• Pharmaceuticals: Complies with USP/NF, EP, and JP standards as an excipient.

• Safety: Generally low toxicity, but PEG derivatives may raise concerns about ethylene oxide residues or irritation in sensitive formulations; typically used at <5% in cosmetics.

Why Choose PEG-30 Dipolyhydroxystearate?

• High Solubilizing Power: Efficiently dissolves oils, waxes, and active ingredients in water, ideal for “oil-in-water” systems.

• Stability: Resists phase separation in high-salt or acidic formulations, making it suitable for challenging environments.

• Sensory Profile: Leaves no sticky residue in skincare, enhancing user experience in light-textured products.
