Question 5

What are the advantages of Emulsifier A-103, oleic acid polyoxyethylene ester, compared to similar products?

Accepted Answer

According to the technical data from Guoli Chemical, Emulsifier A-103 (oleic acid polyoxyethylene ester) has **core competitive advantages of extremely high monoester content (≥95%), excellent chemical stability, precise HLB value (11.5), and wide multi-field applicability** compared to similar products on the market, which makes it particularly outstanding in terms of emulsification efficiency, formulation stability, and process simplification. ### Detailed Description The emulsifier A-103 produced by Guoli Chemical is a nonionic surctant with the chemical composition of oleic acid polyoxyethylene ester. Compared with ordinary similar products, its advantages are not only reflected in a single performance but also in the balance of comprehensive application effects: 1. **High monoester content, stronger emulsifying power** Through advanced synthesis processes, the monoester content of A-103 is as high as 95% or more, with diester content controlled below 2%. High monoester content means a more regular molecular structure, stronger directional adsorption capacity, and the ability to form a denser and more stable intercial film at the oil-water interce, thereby achieving efficient emulsification with a lower addition amount and obtaining a finer and more stable emulsion. 2. **Excellent acid, alkali, and hard water stability** Although oleic acid esters hydrolyze under strong acids and alkalis, A-103 exhibits excellent chemical stability in conventional application pH ranges and hard water environments. This means products formulated with it (such as cutting fluids and cleaning agents) have a longer service life and more reliable on-site performance, and are less likely to il due to fluctuations in water quality or pH. 3. **Precise HLB value and controllable hydrophilic-lipophilic balance** The HLB value of A-103 is 11.5. Emulsifiers in this range are very suitable for preparing oil-in-water (O/W) emulsions. Key indicators such as its cloud point (70-85°C) and surce tension (30-35 mN/m) are precisely controlled, which provides formulation engineers with highly predictable performance, enabling precise compounding and reducing the cost of R&D trial and error. 4. **Wide application adaptability and synergy** As a nonionic surctant, A-103 exhibits a broad application platform characteristics: - **Multifunctionality**: A single agent can provide emulsification, wetting, dispersion, solubilization, and even lubrication effects, simplifying the raw material management of complex formulations. - **Excellent compatibility**: It can synergize well with anionic, cationic, and other nonionic surctants, providing great convenience for constructing high-performance composite systems. - **Low foaming property**: It inherently has low foam, making it very suitable for industrial operation scenarios that require rapid rinsing, pump circulation, or have anti-foaming requirements. ### Core Performance Data Comparison Advantages The following technical parameters reflect the precise quality control of A-103: | Technical Parameter | Index Range | Advantage Interpretation | | :--- | :--- | :--- | | **Monoester Content** | **≥95%** | **Much higher than general similar products** (usually 50-80%), providing stronger emulsifying power and stability. | | **HLB Value** | **11.5** | Precisely positioned in the high-efficiency range of O/W emulsifiers, with good hydrophilic-lipophilic balance. | | **Acid Value** | ≤2 mg KOH/g | Very few unreacted tty acids, low irritation, high product purity, more stable formulation presentation. | | **Active Content** | ≥99% | Almost no diluents or fillers, high solids content, outstanding cost performance. | | **Surce Tension** | 30~35 mN/m | High efficiency, can quickly wet substrates and disperse systems. | | **Iodine Value** | 40~60 g I₂/100g | Retains oleic acid unsaturated double bonds, imparting good skin feel and low-temperature fluidity. | ### Application Suggestions and Scenario Advantages Leveraging the above advantages, A-103 outperforms ordinary products in key areas: - **Cosmetic creams/lotions**: Due to its high monoester content, the resulting cream is finer and glossier, with a light and non-greasy skin feel, and it is not prone to layering or precipitation during long-term storage. - **Metalworking fluids**: As the core emulsification and lubrication component of full-synthetic and semi-synthetic systems, its high stability can resist microbial attack and metal ion interference, significantly extending the life of cutting fluids, while providing certain boundary lubrication protection to improve the surce finish of workpieces. - **Pesticide emulsifiable concentrates/microemulsions**: The HLB value of 11.5 provides excellent compatibility and solubilization effects for various pesticide technical materials (such as EC), and the formed diluted emulsion automatically disperses well with good wetting and spreading properties, voring efficacy. - **Industrial hard surce cleaners**: Efficiently emulsifies oil stains, has good fluidity even at low temperatures, and the low-foaming property cilitates subsequent high-pressure mechanical rinsing. ### Precautions - Although chemically stable, in strongly alkaline systems with high pH, its ester groups still have a risk of hydrolysis under long-term high temperature; stability tests should be conducted during formulation development. - Operation should still follow GHS warnings: **May cause skin and eye irritation**, requiring appropriate protective gloves and goggles. Please refer to the Safety Data Sheet (SDS) for details.

Question 8

How to use Emulsifier A-103, Oleic Acid Polyoxyethylene Ester? What is the recommended dosage?

Accepted Answer

The recommended dosage of Emulsifier A-103 is 1%~5% of the total formulation, and the specific amount should be determined through experiments based on the application system and the emulsified object. Detailed Description Emulsifier A-103 (Oleic Acid Polyoxyethylene Ester) is a nonionic surctant with an HLB value of approximately 11.5. It is easily soluble in water and can be dispersed in water to form a stable emulsion. As an O/W emulsifier, it is suitable for dispersing oil phases (mineral oil, vegetable oil, organic solvents, etc.) into the water phase. Before use, check its state: at room temperature, it is a light yellow liquid to paste. If solidification or separation occurs, heat it to 30~40°C to restore fluidity before sampling; this will not affect the performance. The addition method is usually to directly add it to the oil phase and heat for mixing, or slowly add it to the water phase under stirring. For large-molecule oils or high-viscosity systems that are difficult to emulsify, it is recommended to use the "emulsifier-in-oil" method: dissolve the emulsifier in the oil phase, then slowly add the water phase under stirring to emulsify. Typical dosage references in various application fields (source: general chemical reference values, specific values should be optimized according to the formulation): recommended addition of 2%~5% in cosmetic creams/lotions; 1%~4% in textile oils; 3%~8% as emulsifying lubricating component in metalworking fluids; 5%~10% as emulsifier in pesticide emulsifiable concentrates; 2%~6% in industrial cleaners; 2%~5% in leather tliquors. The above are empirical reference values; the actual dosage should be determined through orthogonal experiments or formulation optimization based on ctors such as formulation compatibility, required emulsion stability, and cost control.

Question 9

What industries and processes are Emulsifier A-103, Oleic Acid Polyoxyethylene Ester mainly used in?

Accepted Answer

Emulsifier A-103 (Oleic Acid Polyoxyethylene Ester) is widely used in six major industries: cosmetics, textiles, metalworking, pesticides, industrial cleaning, and leather, primarily serving as an efficient nonionic emulsifier, dispersant, and lubricant. Detailed Description Emulsifier A-103 is a nonionic surctant of the oleic acid polyoxyethylene ester type, with CAS No. 9004-96-0, an HLB value of approximately 11.5, easily soluble in water, appearing as a light yellow liquid to paste. Its molecular structure combines a hydrophilic polyoxyethylene chain with a lipophilic oleate group, significantly reducing intercial tension at low addition levels, rapidly forming stable, fine oil-in-water (O/W) emulsions, while also offering excellent wetting, dispersing, and chemical stability, maintaining activity in weak acid, weak base, and hard water environments. Thanks to its broad-spectrum emulsifying capability and low-foaming properties, A-103 can effectively emulsify various mineral oils, animal and vegetable oils, and organic solvents, preventing oil-water separation and improving the suspension state of solid particles. Its versatility allows a single raw material to play multiple roles in formulations such as emulsifying, solubilizing, and lubricating, simplifying processes and reducing costs, thus becoming a key auxiliary in many industrial fields. Core Application Industries and Processes According to the Guoli Chemical product database, the specific applications of Emulsifier A-103 are as follows: Cosmetics and Personal Care Products: Used as a primary emulsifier or co-emulsifier in formulations such as creams, lotions, and cleansing oils, imparting a light skin feel, aiding uniform distribution of active ingredients, and building stable product appearance. Textile Printing and Dyeing Auxiliaries: Serves as a key component of synthetic fiber spinning oils, providing lubricity and cohesion to reduce breakage; also acts as a leveling agent to improve dye dispersion uniformity, reduce dyeing defects, and enhance bric hand feel. Metalworking Fluids: Plays a dual role of emulsification and boundary lubrication in formulations for cutting fluids, rolling oils, and wire drawing fluids, providing cooling and lubrication, protecting tools and workpieces, extending service life, and improving machining accuracy. Pesticide Formulations: Used as an emulsifier for emulsifiable concentrates (EC), microemulsions (ME), and other formulations, significantly improving the dispersion, stability, and wetting/spreading properties of pesticide active ingredients on target plants, thereby enhancing efficacy. Industrial Cleaners: Formulates water-based or semi-water-based hard surce cleaners, effectively emulsifying and removing heavy greases, waxes, and organic residues from metal and non-metal surces, suitable for degreasing and precision cleaning processes. Leather Chemicals: Applied in tliquoring processes as a tliquoring agent, helping oils penetrate leather fiber, imparting soft and full hand feel to the finished leather, and improving its extensibility and surce finishing effects.

Do not discharge waste liquid containing the product directly into water bodies or soil after operation; dispose of as hazardous waste through qualified agencies.

Question 10

What are the physicochemical technical parameters of emulsifier A-103 (oleic acid polyoxyethylene ester)?

Accepted Answer

Emulsifier A-103 (oleic acid polyoxyethylene ester) has complete physicochemical parameters. Key indicators include HLB value 11.5, cloud point 70~85°C, surce tension 30~35 mN/m, etc. Data are all from the Guoli Chemical product database. Detailed Explanation Emulsifier A-103 (CAS No.: 9004-96-0) is a nonionic surctant with the chemical name oleic acid polyoxyethylene ester, molecular formula C₁₈H₃₃O₂(C₂H₄O)nH, and molecular weight of approximately 680 (corresponding to EO=9). At room temperature, it appears as a light yellow liquid to paste, with a freezing point below -10°C, flash point >150°C, low hygroscopicity, and excellent chemical stability. However, special attention should be paid to its tendency to hydrolyze easily in acidic and alkaline media. The product is readily soluble in water. The pH range of a 1% aqueous solution is 5.0~9.0, showing weak acidity to weak alkalinity overall. In terms of intercial properties, the product has an HLB value of 11.5, making it an O/W type emulsifier. The surce tension of a 1% aqueous solution can be reduced to 30~35 mN/m (25°C), and the critical micelle concentration (CMC) is approximately 1×10⁻⁴~5×10⁻⁴ mol/L, indicating that it can form micelles and exert wetting and emulsifying effects at relatively low concentrations. The monoester content in the molecule is ≥95%, diester content In terms of functional indicators, the iodine value of 40~60 g I₂/100g reflects the degree of unsaturation of the oleic acid residue in the molecular chain (unsaturation 1.5~2.3 mol/kg). The hydroxyl value of 80~110 mg KOH/g, acid value ≤2 mg KOH/g, saponification value of 80~90 mg KOH/g, etc., collectively characterize the degree of esterification and free acid control level. The foam property is low to medium foam, and the penetration power is 20~60 seconds, making it suitable for industrial formulation systems with foam control requirements.
