Question 8

How to use Oleth-5? What is the recommended addition amount?

Accepted Answer

Oleth-5 is a nonionic W/O emulsifier with an HLB value of 9. The usage method and addition amount need to be determined according to the specific application scenario. The product database does not yet provide fixed recommended addition amounts for various fields. The following are general industry reference ranges. Detailed Description Oleth-5 (Oleth-5) is a high-purity (active content ≥99%) nonionic surctant produced by Guoli Chemical. It appears as a colorless to light yellow transparent liquid. Its HLB value is 9, indicating strong lipophilicity and easy solubility in oils, making it suitable for preparing water-in-oil (W/O) emulsion systems. In actual use, Oleth-5 is often used as a primary emulsifier or co-emulsifier in combination with other surctants to achieve optimal emulsification effects and formulation stability. Basic operation steps during use: According to the formula requirements, Oleth-5 can be directly added to the oil phase and stirred evenly, then mixed with the water phase for emulsification; it can also be slowly added to the water phase under stirring conditions. For formulations that require heating (such as cream-type cosmetics), it is recommended to pre-add Oleth-5 to the oil phase and heat to 70-80°C, then mix with the heated water phase for homogenization emulsification. For room temperature formulations (such as industrial cleaners), it can be directly stirred and dispersed at room temperature. Since the product has a cloud point of 55~65°C and excellent acid and alkali resistance, it can remain stable over a wide pH range. Reference Addition Amounts in Various Fields The Guoli Chemical product database does not yet provide fixed recommended addition amounts for Oleth-5 in various application fields. The following are reference dosage ranges based on product characteristics and general industry practices. Specific amounts should be verified through formulation experiments: Application Field Reference Addition Amount (wt%) Usage Instructions Cosmetics (Creams/Lotions) 0.5% – 5.0% Used as a W/O primary emulsifier or co-emulsifier, combined with emulsifiers having higher HLB values Cosmetics (cial Cleansers/Shampoos) 0.3% – 2.0% Used as a solubilizer to help evenly disperse active ingredients and fragrances Industrial Liquid Cleaners 1.0% – 10.0% Acts as a wetting and emulsifying component, significantly reducing surce tension to enhance cleaning power Textile Scouring Agents/Leveling Agents 2.0% – 8.0% Provides penetration and emulsification performance, promoting uniform dye uptake Metalworking Fluids (Cutting Fluids/Emulsifying Oils) 3.0% – 15.0% Acts as an emulsifying and lubricating component, forming a stable oil-water emulsion system Pesticide Formulations (Emulsifiable Concentrates/Microemulsions) 2.0% – 10.0% Helps the active ingredient to self-emulsify rapidly upon dilution, forming a uniform and stable emulsion Application Recommendations With an HLB value of 9, Oleth-5 is a lipophilic emulsifier particularly suitable for preparing W/O emulsion systems. In actual formulation development, it is recommended to combine it with oil-in-water (O/W) emulsifiers having higher HLB values (such as Oleth-10, Oleth-20, and other high-addition-number Oleth series products) to achieve a wider emulsification range and more stable emulsification effects. For formula systems requiring HLB value adjustment, precise control can be achieved by varying the ratio of surctants with different HLB values based on the target oil phase HLB value. Since Oleth-5 has a surce tension of approximately 30 mN/m and a critical micelle concentration of about 40 mg/L, it can exert significant wetting and emulsifying effects at relatively low concentrations. It is recommended to start formulation experiments with lower addition amounts and gradually optimize to the best dosage, balancing performance and cost-effectiveness. Precautions Please wear protective gloves and goggles during operation. The product may cause skin and eye irritation (GHS classification: Skin irritation Category 2, Eye irritation Category 2). Recommended storage temperature 5–35°C. Avoid high temperature, direct sunlight, and freezing conditions to prevent product deterioration or separation. This product is easily soluble in oil. When preparing O/W emulsions, it is recommended to pre-mix it with the oil phase before emulsifying with the water phase. Do not discharge waste liquid into natural water bodies arbitrarily. The product is harmful to aquatic life with long-lasting effects (H412). The above addition amounts are general industry reference ranges. The actual optimal dosage should be determined through formulation experiments. Guoli Chemical can provide further technical support.

Minor batch-to-batch variations may occur; please refer to the specific batch Certificate of Analysis (COA) for exact values. Application Recommendations Based on the above physicochemical parameters, the recommended usage of this product in different application fields is as follows: Cosmetic Creams\/Lotions: As a W\/O emulsifier, recommended dosage 1%~5%, heat together with the oil phase to 70~80°C for emulsification. The HLB value of 9 is suitable for combination with co-emulsifiers having HLB values of 3~6, giving the formulation a delicate skin feel and excellent high- and low-temperature stability. Industrial and Household Cleaners: Add at 0.5%~3% into the formulation, utilizing its low surce tension (~30 mN\/m) and low CMC (about 40 mg\/L) for rapid wetting and penetration of oils. The low-foaming property is especially suitable for high-pressure spraying and automatic circulation cleaning systems. Textile Scouring Agents\/Leveling Agents: Recommended dosage 2%~8%, leveraging its excellent permeability and alkali resistance to maintain stable emulsifying and detergency effects in high-temperature alkaline scouring baths. Metalworking Fluids: Uses as a primary emulsifier or co-emulsifier in cutting fluids and rust-preventive emulsified oils. Recommended dosage 3%~10%. The product is easily soluble in oil, helping to form a stable oil-in-water emulsified system while providing a low coefficient of friction and good lubricity. Pesticide Emulsifiable Concentrates\/Emulsion in Water: As an emulsifying dispersing aid, recommended dosage 5%~12%. Upon dilution, it promotes self-emulsification of the active ingredient to form a uniform emulsion, enhancing the wetting and spreading performance of the spray liquid on target surces. Precautions During operation, always wear nitrile or neoprene protective gloves and sealed safety goggles to avoid direct contact with skin and eyes. Ensure good ventilation in the workplace to avoid inhaling vapors or aerosols. Store at temperatures between 5~35°C, away from strong oxidizers and open flames, and avoid exposure to high temperatures, sunlight, and freezing. This product is harmful to aquatic life. Do not discharge untreated wastewater directly into sewers or natural water bodies; dispose according to local environmental regulations. The product has a freezing point below 0°C and remains flowable at low winter temperatures. However, it is recommended to slightly warm up the product before use to ensure uniformity.
