Question 2

What should be done if problems occur during the use of thickener 6000DS, thickener 638, and PEG-150? How to get technical support?

Accepted Answer

According to the technical data of Guoli Chemical, the product database does not include problem handling procedures or technical support contact information. Therefore, specific troubleshooting steps or official support channels cannot be provided. However, I can offer a general troubleshooting approach based on product characteristics and suggest ways to obtain assistance. --- **General Troubleshooting Approach** When thickener 6000DS (powder), thickener 638 (liquid), or PEG-150 series il to achieve the expected thickening effect or cause anomalies in application, check the following aspects one by one: 1. **Dissolution and Dispersion Process** - **6000DS (powder)**: Ensure it is slowly added to water under stirring to avoid forming insoluble "fish-eye" clumps. Water temperature is recommended at 20℃~40℃; overheating may cause local hydrolysis or uneven dispersion. - **638 (liquid)**: Although easy to disperse, if the system viscosity is already high, pre-dilute with water or a solvent from the formula before adding to ensure uniform mixing. - All grades require sufficient stirring for 20~30 minutes for complete hydration to achieve final viscosity. 2. **Formula Compatibility Check** - This product is non-ionic and should be compatible with most anionic, cationic, and non-ionic systems. If the formula contains high concentrations of electrolytes, strong acids, strong bases, or certain polar solvents, thickening efficiency may be reduced. - If thinning (viscosity decrease) occurs: Check for cosolvents that reduce cloud point (e.g., ethanol, isopropanol), or if the system temperature exceeds the cloud point causing precipitation. - If turbidity or precipitation occurs: Investigate the presence of incompatible anionic polymers or high salt concentrations. 3. **pH and Water Quality Effects** - Data clearly states this product is "acid-resistant, alkali-resistant, and hard-water-resistant," but extreme pH (e.g., 12) may still cause slow degradation over time. Calcium and magnesium ions in hard water usually do not affect non-ionic thickeners, but when combined with anionic systems, hard water may cause surctant precipitation, indirectly affecting overall rheology. 4. **Recommended Dosage** - **6000DS (powder)**: 0.5%~2.0% in shampoo/shower gel; 0.3%~1.5% in water-based coatings. - **638 (liquid)**: 1.0%~3.0% in shampoo/shower gel; 0.5%~2.0% in coating systems. Insufficient addition results in poor thickening; excessive addition may cause overly strong thixotropy or gel formation. Determine optimal dosage through small-scale trials. 5. **Storage and Shelf Life** - Product shelf life is two years from production date under unopened, cool, and dry conditions (temperature <45℃, humidity <70%). If powder clumps or liquid layers severely separate, it may be due to moisture absorption or storage temperature fluctuations, affecting dissolution and thickening performance. --- **How to Get Technical Support** As the database does not include contact phone numbers, website, or direct technology department information, it is recommended to obtain assistance through the following channels: - **Visit the official website**: Search for "Hai'an Guoli Chemical Co., Ltd." official website. The "Contact Us" or "Service Support" page usually provides technical hotline, email, or online message form. - **Contact supply channel**: Directly contact the distributor from whom you purchased the product or Guoli Chemical sales personnel. They can transfer your inquiry to technical engineers. - **Provide detailed information**: When seeking help, prepare product grade, batch number, dosage, process conditions (temperature/pH/addition order), full formula ingredient list (confidential parts can be hidden), and specific phenomenon description. This will greatly improve communication efficiency. If you need me to check other technical parameter sheets for the product, please specify the product grade.

Dispose of waste in accordance with local environmental regulations; do not discharge into drains or water bodies.

Question 8

How to use thickener 6000DS, thickener 638, and PEG-150? What is the recommended dosage?

Accepted Answer

Thickener 6000DS (powder) and thickener 638 (liquid) are both PEG-150 distearate nonionic thickeners, differing in form and dispersion method; the recommended dosage is typically 0.5%~5.0% of the total formulation, and the optimal amount should be determined through experimentation based on target viscosity. Detailed Explanation Thickener 6000DS is a white to off-white powder that needs to be dispersed and dissolved in hot water, suitable for water-based formulations requiring precise metering and with low clarity requirements. Its thickening mechanism involves full hydration and swelling under heating (usually 60~75°C), forming a stable thickening network upon cooling, making it more suitable for hot-mix processes. It is widely used in industrial fields such as water-based coatings, adhesives, and textile printing pastes. Thickener 638 is a slightly yellow transparent liquid, a pre-dispersed or modified version of 6000DS. Its biggest advantage is supporting cold-mix processes—it can be directly added to the system at room temperature with stirring, greatly simplifying production and reducing energy consumption. It is particularly suitable for water-based formulations with certain clarity requirements or without heating cilities, such as water-based industrial coatings, latex paints, and water-based inks. PEG-150, as the main chemical name of this series, generally refers to polyethylene glycol (150) distearate thickeners. Its nonionic nature allows good compatibility with anionic, cationic, and nonionic surctant systems. In personal care products such as shampoos, body washes, and creams, it acts as both a thickener and an emulsion stabilizer, while also improving foam texture and product suspension ability. Usage Methods and Recommended Dosage The product database of Guoli Chemical does not provide exact recommended dosages for each product (actual usage varies greatly depending on formulation system, target viscosity, pH, compatibility with other raw materials, etc.). The following is a reference guide based on product characteristics and industry common practices: Usage Method for Thickener 6000DS (Powder) Pre-dispersion: Slowly add the powder to deionized water (water temperature 60~75°C) while stirring to avoid clumping. Alternatively, pre-mix with a small amount of glycerin or propylene glycol to form a slurry before adding to the water phase. Full hydration: Maintain temperature at 65~75°C and stir for 20-30 minutes until the powder is fully swollen and hydrated, resulting in a uniform thickening state. Cooling and setting: Cool to room temperature while stirring; the viscosity will further increase and stabilize. Add to formulation: Mix the pre-made thickener base with other components, or add directly during the heating stage of the formulation's water phase. Reference dosage range (based on total formulation): Water-based architectural coatings/latex paints: 0.3%~1.5% Water-based adhesives: 0.5%~2.0% Water-based inks: 0.3%~1.0% Textile printing pastes: 1.0%~3.0% Usage Method for Thickener 638 (Liquid) Direct addition: Add the liquid 638 directly to the water-based system while stirring, without pre-heating. Thorough stirring: Stir at medium speed for 15-30 minutes until evenly dispersed; the system viscosity gradually builds up. Adjust pH: Although this product has a wide pH tolerance, thickening efficiency is optimal in the pH 5.5~8.0 range for some systems. Fine-tune pH using pH adjusters if needed. Reference dosage range (based on total formulation): Latex paints: 0.5%~2.5% Water-based industrial coatings: 0.3%~1.5% Water-based adhesives: 0.5%~2.0% Water-based inks: 0.3%~1.0% Use of PEG-150 in Personal Care Products Usually added in powder form (6000DS) during the heating stage of the formulation's water phase, dissolved and dispersed together with surctants at 70~75°C, then cooled with stirring to achieve thickening. Reference dosage: Shampoo/body wash 0.5%~2.0%; Creams/lotions 1.0%~3.0%; Detergents 0.3%~1.5%. Application Suggestions Selection suggestion: If heating cilities are available and the formulation uses a hot-mix process, recommend the lower-cost thickener 6000DS powder; if process simplification, cold-mix operation, or clarity requirements are needed, prioritize thickener 638 liquid. Dosage optimization: For first use, start with gradient tests from the lower end of the recommended range (e.g., 0.3%, 0.5%, 1.0%, 2.0%), plot a dosage-viscosity curve, and determine the most economical dosage for the target product. Order of addition: In surctant-containing systems (e.g., shampoo), it is recommended to dissolve PEG-150 together with surctants in the hot water phase first, then gradually add other components for optimal thickening efficiency and transparent appearance. Avoid over-thickening: Excessive dosage may cause the system to become gel-like, poor flow, or "whitening" during application; evaluate based on sensory experience and application performance. Precautions Safety protection: When handling, it is recommended to wear a dust mask (when handling powder), chemical safety goggles, and protective gloves to avoid dust inhalation and prolonged contact with eyes and skin. Moisture-proof storage: The product is slightly hygroscopic (especially powder type 6000DS). After opening, seal immediately and store in a cool, dry place with temperature not exceeding 45°C and relative humidity below 70%. Shelf life: two years. Electrolyte effect: High concentrations of electrolytes (e.g., salts) may reduce the thickening efficiency of nonionic thickeners. If the formulation contains salts, increase dosage appropriately or verify in advance. Dust safety: 6000DS powder is not flammable, but fine dust accumulation mixed with air may form flammable dust clouds. Keep the operation area away from open flames and heat sources, and maintain good ventilation.

Question 9

Thickener 6000DS, Thickener 638, and PEG-150 are mainly used in which industries and processes?

Accepted Answer

Thickener 6000DS, Thickener 638, and PEG-150 cover two major sectors: industrial and daily chemical, and are widely used in multiple industries such as coatings, adhesives, inks, textiles, personal care products, and detergents. Detailed Description Guli Chemical's PEG-150 distearate series thickeners are non-ionic high-efficiency thickeners, including Thickener 6000DS (powder) and Thickener 638 (liquid) grades, to suit different process needs. With excellent thickening efficiency, outstanding compatibility (good compatibility with anionic, cationic, and non-ionic systems), and stability against acid, alkali, and hard water, this series is an ideal choice for thickening modification in water-based systems. In terms of industry distribution, the industrial field is its main area, covering water-based architectural coatings, water-based adhesives, water-based inks, textile printing pastes, textile lubricants, and industrial mold release agents; the daily chemical and personal care fields involve shampoos, body washes, creams, lotions, and household detergents. The two grades have different focuses in application: powder type 6000DS is more suitable for scenarios requiring precise metering and long-term storage, while liquid type 638 is superior in production convenience due to easy dispersion and suitability for cold blending processes. In actual process applications, Thickener 6000DS and 638 mainly play a role in dilution, dispersion, grinding, and filling stages of water-based system formulations, optimizing application performance (such as roll coating, brush coating, spray coating, printing) and storage stability (anti-settling, anti-stratification) by adjusting system viscosity. PEG-150 is more often used in formulations containing surctants (such as shampoos, body washes, detergents) to provide thickening and suspension stabilization, while enhancing the sensory experience, such as foam texture, cream fineness, and smooth application.

Both belong to the PEG-150 distearate series with the same core thickening mechanism, and can also be used together when both production efficiency and storage convenience need to be considered. Dosage Reference: This series has high thickening efficiency. Generally, a low dosage (usually 0.5%-3% of the total formulation, specific dosage depends on target viscosity and system characteristics, to be determined by experiments) can achieve ideal rheological properties in water-based systems. It is recommended to determine the optimal addition amount through gradient tests during the laboratory stage of formulation development. Addition Process: Thickener 638 liquid can be directly added to cold blending systems with stirring dispersion; Thickener 6000DS powder should be slowly added under high-speed stirring to ensure full dissolution and dispersion, avoiding clumping. Both can be added at different stages of the formulation, but it is recommended to complete the thickener addition before pH adjustment to achieve the best thickening effect. Precautions Storage Conditions: It is recommended to store at temperatures not exceeding 45°C, relative humidity below 70%, sealed in a cool and dry place, away from strong acids, strong bases, and strong oxidizers. The powder type 6000DS requires special attention to moisture prevention to avoid caking due to moisture absorption. Operational Safety: It is recommended to wear dust masks, safety goggles, and protective gloves during operation. Although the product is non-toxic and non-flammable, accumulated fine dust mixed with air may form combustible dust clouds, so keep away from open flames and heat sources. Shelf Life: The unopened product has a valid shelf life of two years under recommended storage conditions. Once opened, it should be resealed and used as soon as possible. Compatibility Test: Although the non-ionic nature of this series gives it broad compatibility, it is recommended to conduct small-scale trial verification for specific formulation systems before large-scale production to ensure compatibility and stability with other components (especially electrolytes, active substances, etc.) in the system.

Question 10

What are the physicochemical and technical parameters of Thickener 6000DS, Thickener 638, and PEG-150?

Accepted Answer

Thickener 6000DS, Thickener 638, and PEG-150 are all PEG-150 Distearate series products with highly consistent physicochemical parameters, the main differences being in appearance (powder vs. liquid) and solubility performance. Detailed Description Thickener 6000DS (white to off-white powder) and Thickener 638 (slightly yellow transparent liquid) are both PEG-150 Distearate. Their core chemical structures are identical, so physicochemical indicators such as acid value, saponification value, and content ll within the same range. The differences lie mainly in appearance and dissolution process: 6000DS is in powder form, convenient for precise measurement and long-term storage; 638 is a liquid, dispersing ster, especially suitable for cold blending processes. PEG-150, as a general-grade raw material, is typically supplied in white to slightly yellow flakes or granules. This series of products are nonionic surctants with an HLB value of approximately 18.5, exhibiting excellent hydrophilicity. They are chemically stable, resistant to acid, alkali, and hard water, maintaining stable thickening effects under complex water quality and broad pH conditions. The products are slightly hygroscopic and require moisture protection during storage; recommended storage temperature is not exceeding 45°C with relative humidity below 70%.

It is recommended to pre-disperse in hot water before adding to the formulation. The dosage is adjusted based on the target viscosity, typically 0.5%~3% of the total formula weight. Thickener 638 (Liquid): More suitable for cold blending processes, widely used in latex paints, water-based industrial coatings, and adhesive systems. It can be added directly under stirring, imparting moderate thixotropy to the system. Recommended dosage is 0.5%~5%. PEG-150 (General Raw Material): An ideal thickener and stabilizer for personal care products such as shampoos, body washes, creams, and lotions. It performs excellently in surctant-containing aqueous systems, with recommended dosage typically ranging from 0.3%~3%. Precautions Dissolution Process: For powder products, it is recommended to slowly add to hot water at 50~70°C under stirring to avoid agglomeration. Personal Protection: It is recommended to wear a mask, goggles, and gloves during operation to avoid inhalation of dust or contact with eyes. Storage Requirements: Store in a cool, dry, and well-ventilated place, temperature not exceeding 45°C, relative humidity below 70%; seal promptly after opening to prevent moisture. Compatibility: Keep away from strong acids, strong alkalis, and strong oxidizing agents. It can be well compounded with most anionic, cationic, and nonionic surctants.
