Oleyl Alcohol Ethoxylate OV-2 (CAS 9004-98-2), also known as Oleth-2, is a high-performance nonionic emulsifier. It features excellent surface activity, effectively reducing oil-water interfacial tension to stabilize emulsions. With low irritation and good compatibility, it works well in a wide pH range (4-8) and blends smoothly with most oils, actives, and surfactants. Ideal for cosmetics, personal care, and industrial formulations, it enhances texture in creams/lotions and aids in dispersion. Its 2 EO groups balance hydrophilic-lipophilic properties, ensuring reliable performance in diverse applications.
Product Advantage
Exceptional Emulsifying Efficiency: With precisely 2 ethylene oxide (EO) groups, this emulsifier achieves stable oil-in-water or water-in-oil emulsions at low concentrations (typically 0.5-3% in formulations). Tests show it reduces interfacial tension to <30 mN/m, ensuring emulsion stability for over 12 months under accelerated aging (45°C).
Superior Compatibility & Versatility: Compatible with 95% of common cosmetic ingredients (oils, actives, surfactants) and stable across pH 4-8. It works seamlessly in both cold and hot processing, reducing production time by 20% compared to conventional emulsifiers in industrial trials.
Gentle & Skin-Friendly: Clinically tested with a 0.01% irritation rate in 500+ human trials, making it ideal for sensitive skin products. Its mild formula meets EU Cosmetics Regulation (EC) 1223/2009 standards, with full compliance documentation available.
Cost-Effective Performance: High active content (min. 99%) ensures lower dosage requirements. Customers report 15-20% cost savings in raw material expenses while maintaining formulation quality, backed by 500+ global client case studies.
Consistent Quality & Supply: Produced via advanced ethoxylation technology with batch-to-batch variation <1%. Annual production capacity of 5,000 tons guarantees stable supply, with ISO 9001 and GMP certifications validating our manufacturing standards.

Product Uses
1、Cosmetic Creams & Lotions
It acts as a primary/auxiliary emulsifier in facial moisturizers, body lotions, and hand creams. With low irritation and HLB 6.5-7.5, it stabilizes oil-water blends (e.g., plant oils + aqueous phases), enhancing product smoothness and extending shelf life.
2、Personal Care Cleansing Products
Applied in makeup removers (oils/creams) and gentle face washes. It helps dissolve cosmetic oils while improving rinsability, reducing residue. Meets EU EC 1223/2009 standards, suitable for sensitive skin formulations.
3、Industrial Metalworking Fluids
Used in water-based metal cutting fluids. Its excellent emulsifying efficiency (works at 0.5-3% dosage) stabilizes mineral oil and additive blends, preventing phase separation and boosting fluid cooling/lubrication performance.
4、Household Cleaning Formulations
Incorporated into liquid detergents and fabric softeners. It lowers interfacial tension, enhancing dirt-removing ability. Compatible with surfactants and pH 4-8 ranges, ensuring stable performance in daily cleaning use.
5、Pharmaceutical Topical Preparations
Applied in ointments and medical emulsions. With ≤10 ppm heavy metals and high purity (≥99%), it meets pharmaceutical safety standards, aiding in uniform dispersion of active ingredients for better skin absorption.
Product Operate Guide
For most formulations, add 0.5-3% of the product (based on total formula weight) to oil phase first. Heat oil phase (30-40℃, matching its cloud point) and water phase to same temp, then mix oil into water with stirring (300-500 rpm) for 10-15 mins. Avoid overheating (>60℃). Adjust pH to 5.0-7.0 if needed. Test small batches first for optimal stability.
FAQ
Q: Can I adjust the dosage if the emulsion is unstable?
A: Yes. If emulsion separates, slightly increase dosage (max 4%, based on total formula) or check temp consistency (30-40℃ for both phases). Avoid exceeding 5% to prevent texture issues.
2. Q: Is it safe to mix with anionic surfactants?
A: Generally yes. It's compatible with most anionic surfactants (e.g., SLS). Test a 1:1 ratio in small batches first, as high anionic concentrations may reduce emulsifying efficiency.
3. Q: How to store it to avoid degradation?
A: Store in a sealed container at 15-30℃, away from direct sunlight and moisture. Unopened, it has a 2-year shelf life; once opened, use within 6 months to maintain performance.
4. Q: Why does the product turn cloudy at low temps?
A: Cloudiness at <15℃ is normal (due to slight crystallization). Warm it to 25-30℃ and stir gently—this won't affect its emulsifying ability or purity.
