Oleyl Alcohol Ethoxylate OV-24 is a high-performance, multi-purpose emulsifier designed for broad industrial and personal care applications. It excels at creating stable oil-in-water (O/W) or water-in-oil (W/O) emulsions, effectively reducing surface tension to blend immiscible ingredients.
With excellent solubility and compatibility, it suits detergents, skincare products (e.g., lotions, creams), household cleaners, and industrial formulations. Boasting high purity and consistent quality, it ensures long-term emulsion stability, enhances product texture, and supports smooth application. Available in bulk quantities, it meets food-grade or industrial standards, making it a reliable choice for manufacturers globally.
Product Advantage
1. Exceptional Emulsion Stability with Proven Data
Oleyl Alcohol Ethoxylate OV-24 delivers industry-leading emulsion stability, maintaining uniform oil-in-water (O/W) or water-in-oil (W/O) blends for up to 18 months under standard storage conditions (25℃, 50% humidity) – a 30% longer retention period than conventional emulsifiers. Its unique ethoxylation structure (24 moles of ethylene oxide) ensures optimal surface tension reduction (to 32 mN/m at 0.1% concentration), preventing phase separation even in high-salt or acidic formulations (pH 4-10), verified by third-party lab tests (Report No. OV24-2024-037).
2. Broad Compatibility & Low Dosage Requirement
This emulsifier exhibits excellent compatibility with over 95% of common cosmetic and industrial raw materials, including surfactants, oils, and active ingredients (e.g., hyaluronic acid, enzymes). Unlike traditional alternatives that require 3-5% dosage, OV-24 achieves stable emulsions at just 1.2-2.0% addition – reducing raw material costs by 25-40% for manufacturers. It also avoids "gritty texture" issues in skincare products, as confirmed by 98% positive feedback from cosmetic formulators in a 2024 customer survey.
3. High Purity & Regulatory Compliance
Produced via a closed-loop ethoxylation process, OV-24 boasts a purity level of 99.5% (min.), with residual ethylene oxide content ≤ 0.1 ppm – far below the EU REACH (≤ 10 ppm) and FDA (≤ 5 ppm) limits. It is cruelty-free, vegan, and complies with global standards: EC 1223/2009 (cosmetics), FDA 21 CFR 172.820 (food contact), and ISO 9001:2015. Each batch comes with a Certificate of Analysis (CoA) to ensure traceability, building trust for clients in strict markets like the EU and North America.
4. Temperature & Shear Resistance for Harsh Conditions
OV-24 maintains stable performance across a wide temperature range (-5℃ to 80℃), with no degradation or efficacy loss even after 5 cycles of freeze-thaw testing (-20℃ to 40℃). It also withstands high-shear mixing (up to 3000 RPM) – critical for industrial applications like metalworking fluids or heavy-duty detergents. In a 6-month field test with automotive cleaners, formulations containing OV-24 retained 92% of their cleaning power, compared to 75% for formulations using competing emulsifiers.
5. Eco-Friendly & Biodegradable Profile
Aligned with sustainable development trends, OV-24 is readily biodegradable (92% biodegradation within 28 days per OECD 301B test), with no bioaccumulation risk in aquatic environments. It is free of parabens, phthalates, and volatile organic compounds (VOCs), making it ideal for "green" product lines (e.g., eco-friendly detergents, natural skincare). This feature has helped 70% of our clients meet their carbon footprint reduction goals (average 15% lower environmental impact vs. prior emulsifiers).

Product Uses
1. Cosmetics & Personal Care
Ideal for lotions, creams, and serums. Its HLB 15.0-16.0 and 18-month emulsion stability prevent phase separation in moisturizers, while low dosage (1.2-2.0%) avoids greasy textures. Complies with EC 1223/2009, making it safe for facial and body care products.
2. Household & Industrial Detergents
Used in liquid detergents (laundry, dishwashing) and hard-surface cleaners. Reduces surface tension (32-35 mN/m) to enhance dirt removal, and withstands pH 4-10, 适配 acidic/alkaline formulas. Biodegradable (≥92%), meeting "green" detergent standards.
3. Metalworking Fluids
Serves as an emulsifier in cutting oils and coolants. Resists high temperatures (-5 to 80℃) and high-shear mixing (3000 RPM), maintaining stable oil-in-water emulsions. Prevents corrosion and improves lubricity, extending tool life.
4. Agricultural Formulations
Added to pesticide emulsifiable concentrates (EC) and foliar fertilizers. Ensures uniform dispersion of active ingredients (e.g., herbicides), enhancing absorption by crops. Compatible with most agrochemicals, no efficacy loss in high-salt environments.
5. Pharmaceutical & Food Processing
Suitable for pharmaceutical creams (e.g., topical ointments) and food-contact lubricants. High purity (≥99.5%) and low residual EO (≤0.1 ppm) meet FDA 21 CFR 172.820. Ensures product safety and compliance with strict health regulations.
Product Operate Guide
Preprocessing: Store at 15-30℃ (avoid direct sunlight/freezing). Stir gently before use to ensure uniformity—no heating needed unless it thickens (warm to 30-40℃ until viscous liquid).
Addition: Add 1.2-2.0% (based on total formulation) to water or oil phase. Mix at 500-1500 RPM for 5-10 mins; high-shear mixing (≤3000 RPM) works for industrial use.
Post-Use: Seal containers tightly after use. Clean tools with warm water (no harsh solvents needed). Avoid contact with eyes—rinse with water if exposed.
FAQ
Q1: How should I store Oleyl Alcohol Ethoxylate OV-24 to maintain its quality?
Store it at 15-30℃ in a sealed, cool, and dry place, avoiding direct sunlight and freezing. If it thickens in low temps, warm to 30-40℃ gently—this won't affect its performance, as it's stable within -5 to 80℃.
Q2: Can OV-24 replace other ethoxylated emulsifiers (e.g., OV-20) in my formulation?
Yes, but adjust dosage: OV-24 (HLB 15.0-16.0) needs 1.2-2.0% (vs. OV-20's 2-3%) for stability. It has higher EO content, so test compatibility first—its 99.5% purity ensures better consistency than lower-grade alternatives.
Q3: Is OV-24 safe for use in food-contact or baby cosmetic products?
Absolutely. It meets FDA 21 CFR 172.820 (food contact) and EC 1223/2009 (cosmetics), with residual EO ≤0.1 ppm (far below safety limits). For baby products, its low irritation and biodegradability (≥92%) make it suitable.
Q4: What if my formulation's pH is outside 5.0-7.0—will OV-24 still work?
It works in pH 4-10 (tested via ASTM E70). Beyond this range, emulsion stability may drop. For acidic/alkaline formulas (e.g., industrial cleaners), add a pH buffer first to keep it within 4-10 for optimal performance.
Q5: How can I verify the purity of the OV-24 batch I receive?
We provide a Certificate of Analysis (COA) for each batch, showing HPLC-tested active content (≥99.5%) and GC-MS results for residual EO. You can also test viscosity (350-500 cSt at 25℃) via ASTM D445 to confirm quality.
