Question 2

What should I do if problems occur during the use of Stearic Acid Polyoxyethylene Ether SG-10? How to obtain technical support?

Accepted Answer

When problems occur during the use of SG-10, first investigate the formulation and process based on the phenomenon, then follow safety instructions for emergency treatment; for technical support, directly contact the sales or technical team of Guoli Chemical. Detailed Explanation Stearic Acid Polyoxyethylene Ether SG-10 (PEG-10 Stearate) is a mature and stable nonionic surctant that generally does not cause problems under normal use. If difficulties arise in practical applications, it is recommended to follow the steps below for troubleshooting: First, confirm whether the product appearance and physical state are normal—the product should be a white to slightly yellow solid or paste with a melting point of 35-40°C. If there is color deepening, severe caking, or off-odor, it may involve improper storage (e.g., exceeding 40°C or moisture ingress). In such cases, suspend use and evaluate quality. Second, check the ionic compatibility and acid-base conditions of the formulation system. Although SG-10 is stable to acids, alkalis, and hard water, improper combinations (e.g., direct mixing with strong oxidizers or high-concentration acids) may still lead to reduced functionality. Common usage problems and handling directions: Poor emulsification effect or unstable emulsion—first verify whether the HLB value matches the system requirements (SG-10 has an HLB value of approximately 13.5, suitable for O\/W emulsions) and confirm whether the addition amount and emulsification process are appropriate. The recommended dosage can be adjusted within 1% to 5% of the total formulation mass; Difficulty in product dissolution—SG-10 is easily soluble in water, but dissolution slows at low temperatures. It can be pre-dispersed in warm water at 40-50°C before adding to the system; Layer separation, precipitation, or abnormal cloud point—the cloud point of this product is approximately 45-55°C. If the system operating temperature is close to or exceeds this range, the nonionic surctant may precipitate, requiring adjustment of the process temperature. If leakage occurs, immediately isolate the contaminated area. For small spills, absorb with sand or inert material and collect in a sealed container. For large spills, contain with dikes and transfer using explosion-proof pumps, avoiding entry into drainage systems and environmental water bodies. Personnel contact: For skin contact with the pure product, rinse with flowing clean water and soap for at least 15 minutes. For eye contact, flush thoroughly with clean water or saline solution for at least 15 minutes. The pure product may cause mild reversible irritation. If discomfort persists after rinsing, seek medical attention. Detailed first aid measures and firefighting measures can be found in the product safety documentation.

The emulsification temperature is suggested to be controlled at 65-75°C. Textile leveling \/ softening treatment: If the hand feel is poor or leveling effect is unsatisctory, check whether the working fluid pH is within the appropriate range (generally 5-7) and whether anionic auxiliaries interact with it. Pre-test the compounding scheme is recommended. Metalworking fluids \/ emulsified oils: If the emulsion is unstable, re-verify the oil-water ratio and addition sequence. It is recommended to first dissolve SG-10 in the oil phase, then slowly add water for phase inversion emulsification. Pesticide emulsifiable concentrates: If layering or flocculation occurs after dilution, check the compatibility of the solvent system with the active ingredient and whether the water hardness is too high. If necessary, add a chelating agent to improve the situation. Notes The product database currently does not publish after-sales phone numbers or online technical support entry points.

Question 5

What are the advantages of Stearic Acid Polyoxyethylene Ether SG-10 compared to other similar products?

Accepted Answer

Among similar stearic acid polyoxyethylene ether series, SG-10, with its HLB value of 13.5, excellent O/W emulsifying ability, and the most balanced hydrophilic-lipophilic performance, has become the most widely used and compatible general-purpose nonionic emulsifier from Guoli Chemical. Detailed Description In comparison with other stearic acid polyoxyethylene ether homologues from Guoli Chemical (such as SG-6, SG-9, and SG-40), the greatest advantage of SG-10 lies in the optimal hydrophilic-lipophilic balance (HLB value 13.5) constructed by its ethylene oxide addition number (n≈10). Compared to SG-6 (n≈6), which is more lipophilic and mainly suitable for W/O systems, SG-10 can more efficiently reduce intercial tension and form stable, fine O/W emulsions. In contrast to SG-40 (n≈40), which is overly hydrophilic, SG-10 is less likely to cause over-emulsification in emulsion polymerization or metalworking fluids, allowing for more precise control of micelle structure and particle size distribution. From the perspective of product form and process convenience, SG-10 appears as a white to slightly yellow paste or solid (melting point 35-40°C). Compared to the flake\/block forms of SG-6 and SG-9, its paste form is easier to handle and dissolves ster, dispersing more quickly in hot water or oil phase, thereby shortening the downstream production cycle. Additionally, SG-10's low-foaming property (no need for additional defoamers), extremely low acid value (≤2 mgKOH\/g), and iodine value (≤2 gI₂\/100g) endow it with excellent chemical stability and freeze-thaw stability, making it less prone to rancidity during long-term storage and transportation, which is especially important in cosmetic cream formulations. In terms of safety and environmental compliance, SG-10 also stands out. Its 5% aqueous solution has a skin irritation index (PII) of only 0–0.5, which is essentially classified as non-irritating. Coupled with its extremely low acute oral toxicity (LD50 > 5000 mg\/kg), freedom from heavy metals and phosphorus, it fully complies with international mainstream cosmetic restricted substance requirements. Combined with its readily biodegradable nature (OECD 301B 28-day degradation rate >60%), SG-10 is a benchmark product in the Guoli Chemical series that simultaneously achieves “high-performance emulsification” and “green safety,” making it especially suitable for personal care and household detergent markets that demand high raw material mildness and environmental footprint. Technical Parameters Parameter SG-10 (Guoli Chemical) Advantages over similar SG series Appearance White to slightly yellow paste\/solid Easier to take out and ster to dissolve than flaky SG-6\/SG-9 HLB value 13.5 Most balanced O\/W emulsifying performance among similar products, widest applicability Cloud point (1% aqueous solution) 45-55°C Moderate cloud point, stable emulsification over a wide temperature range Active content ≥99% High purity, no excess fillers pH (1% aqueous solution) 5.0-7.0 Near neutral, minimal pH interference to formulation systems Acid value ≤2 mgKOH\/g Very low acid value, excellent chemical stability, not prone to rancidity Iodine value ≤2 gI₂\/100g Very high saturation, strong antioxidant capacity Skin irritation (5% dilution) Non-irritating (PII 0-0.5) Represents industry-leading mildness and safety Monoester content ≥95% Higher monoester content indicates purer O\/W emulsifying ability Application Suggestions Due to its balanced HLB value (13.5), SG-10 is especially suitable as the primary emulsifier for O\/W creams, lotions, pesticide emulsifiable concentrates, and metalworking fluids. In practical formulation design, the recommended dosage is typically 5%–20% of the oil phase mass. For polymer emulsion synthesis requiring higher low-temperature stability, SG-10 can effectively control particle size distribution; when used as a leveling agent or soaping agent in textile printing and dyeing, its low-foaming property prevents dye overflow and imparts a smooth handfeel to the bric. Note that for highly polar or ultra-long-chain oils, it can be compounded with a small amount of more hydrophilic surctant to achieve better emulsification results. Precautions The pure product is slightly reversible irritating to the eyes; wearing goggles is recommended during production feeding. The paste product may harden at low winter temperatures; before use, it can be pre-warmed at 25-35°C to restore fluidity. Do not use open flames for heating. Although it is a low-toxicity, readily biodegradable product, large amounts of untreated wastewater should still be avoided from being discharged directly into water bodies.

Question 8

How to use polyoxyethylene stearate SG-10? What is the recommended dosage?

Accepted Answer

Polyoxyethylene stearate SG-10 should be added to the system in an appropriate manner according to the application scenario before use. The recommended dosage varies across different application fields, ranging from 0.5% to 15%. Detailed Description Polyoxyethylene stearate SG-10 (PEG-10 stearate) is a white to slightly yellow solid or paste (melting point 35-40°C), classified as a nonionic surctant with an HLB value of approximately 13.5. It is easily soluble in water, ethanol, acetone, and other organic solvents. In practical use, because it is solid or paste at room temperature, it is recommended to heat it to 40-50°C to melt or soften it first, then mix it evenly with the oil phase components, followed by conventional O/W emulsification for homogenization. This product has good compatibility with anionic, cationic, and nonionic surctants and can be used in combination to achieve synergistic effects. SG-10 primarily acts as an O/W emulsifier, wetting dispersant, and stabilizer in formulations. Its polyoxyethylene chain provides hydrophilicity, while the stearate ester group provides lipophilicity. Together, they effectively reduce the oil-water intercial tension, forming a stable and fine emulsion system. The product is resistant to acids, alkalis, and hard water, exhibiting excellent chemical stability, and its low-foaming property minimizes foam-related issues in industrial applications. Since the specific recommended dosages for various application fields are not yet included in the product database of Guoli Chemical, the following dosage suggestions are general industry reference ranges.

Accepted Answer

Stearyl Polyoxyethylene Ether SG-10 is a nonionic O/W emulsifier with an HLB value of approximately 13.5. It appears as a white to slightly yellow pasty solid at room temperature, with excellent comprehensive physicochemical properties, suitable for multiple industries such as cosmetics, textiles, and pesticides. Detailed Description Stearyl Polyoxyethylene Ether SG-10 (CAS: 9004-99-3), chemical name Polyoxyethylene (10) Stearate, contains about 10 ethylene oxide addition units in its molecular structure, with a molecular weight of approximately 725. This product is a classic nonionic tty acid polyoxyethylene ester surctant. The synergistic effect of the hydrophilic polyoxyethylene chain segment and the lipophilic stearate group provides excellent O/W emulsifying ability and wide formulation compatibility. The product appears as a white to slightly yellow solid or paste, with a melting point range of 35-40°C. Its kinematic viscosity at 40°C is approximately 50-80 mPa·s. It is easily soluble in polar solvents such as water, ethanol, and acetone. The pH of a 1% aqueous solution is between 5.0 and 7.0. It is chemically stable, resistant to acids, alkalis, and hard water. The cloud point range is 45-55°C, making it a low-foaming product.

Due to its cloud point of 45-55°C and low-foaming nature, it performs prominently in industrial cleaning and other scenarios requiring low-foaming properties. In terms of compatibility, SG-10 can be well compounded with various anionic, cationic, and nonionic surctants, broadening the performance window of the formulation. Storage is recommended at temperatures not exceeding 40°C, avoiding moisture absorption and caking. Precautions The pure product causes mild reversible eye irritation. It is recommended to wear chemical safety goggles during operation. A 5% dilution is non-irritating to the skin, but prolonged and repeated contact with the pure product may cause skin dryness. Storage temperature is recommended not to exceed 40°C. Keep the container tightly sealed to prevent moisture absorption. The product is readily biodegradable (degradation rate exceeding 60% in 28 days under OECD 301B conditions), but direct discharge into water bodies should still be avoided.
