Thickener 6000DS, Thickener 638, and PEG-150 are all non-ionic high-efficiency thickeners of the PEG-150 Distearate series. They are widely used rheological modifiers in water-based systems, combining thickening, emulsifying, and lubricating functions.
Detailed Description
This series of products is based on polyethylene glycol (150) distearate (CAS No.: 9005-08-07) as the core component, supplied by Hai'an Guoli Chemical Co., Ltd. in two different grades. Thickener 6000DS is a white to off-white powder form, which facilitates precise measurement and long-term storage. Thickener 638 is a slightly yellow transparent liquid with excellent dispersibility, especially suitable for cold blending processes, effectively reducing production energy consumption.
As non-ionic surfactants, their greatest advantage lies in wide compatibility with anionic, cationic, and non-ionic systems. They also exhibit excellent resistance to acids, alkalis, and hard water, maintaining stable thickening effects under complex water conditions and a wide pH range, making them highly reliable functional additives in water-based formulations.
This product is non-toxic, non-flammable, and safe for humans and the environment under normal use conditions. Under recommended storage conditions (temperature not exceeding 45°C, relative humidity below 70%), unopened products have a shelf life of two years.

Main Uses
Industrial Fields
Thickener 6000DS is designed for water-based systems, providing efficient thickening and good flow and leveling properties:
- Water-based architectural coatings (latex paints): Offers excellent thickening, anti-settling, and anti-spattering capabilities, significantly improving brushing and rolling feel, and helping to form uniform thick films.
- Water-based adhesives: Accurately adjusts viscosity, enhances initial tack and storage stability, and prevents filler settling and stratification.
- Water-based inks: Optimizes ink thixotropy and rheological curves, ensuring sharp dots, vibrant colors, and minimal misting during high-speed printing.
- Textile printing pastes: Enhances the water retention and plastic viscosity of the paste, resulting in sharp print contours, bright colors, and reduced bleeding.
Thickener 638 acts as a universal rheology modifier, imparting moderate thixotropy to the system:
- Latex paints: Balances low and medium shear viscosity, enhances the in-can effect and film leveling, and reduces spattering and sagging during application.
- Water-based industrial coatings: Adjusts application viscosity on substrates such as metal and plastic, improves anti-settling and hiding power, and maintains stable gloss.
- Water-based adhesives: Controls the consistency of the adhesive, extends open time, improves wet tack without affecting final bond strength.
- Water-based inks: Provides the rheology required for printability, ensuring good transfer without screen clogging, resulting in fine and clear impressions.
Household and Personal Care Fields (PEG-150 General)
Due to its non-ionic nature and wide compatibility, PEG-150 plays a role in thickening and stabilizing surfactant-containing formulations:
- Shampoos, body washes, creams, lotions: Imparts desirable viscosity and suspension ability, enhances foam texture, makes creams fine and smooth to apply.
- Household and industrial detergents: Adjusts the viscosity of cleaning solutions, improves clinging properties and user experience, helps stabilize fragrances and other additives.
- Textile lubricants: Acts as a consistency regulator and protective colloid, reducing friction during spinning or weaving, preventing fiber damage.
- Industrial mold release agents: Increases the film-forming property and adhesion viscosity of the release agent system, ensuring uniform coverage on the mold surface for efficient and non-damaging demolding.
Precautions
- It is recommended to wear dust masks, chemical safety goggles, and protective gloves during operation to avoid direct contact with eyes and skin.
- The work area should be well ventilated. Accumulated fine dust may form a combustible dust cloud, so keep away from open flames, heat sources, and strong oxidizers.
- Store in a cool, dry, well-ventilated warehouse, away from moisture and direct sunlight. Recommended storage temperature should not exceed 45°C.
- If not completely used after opening, reseal tightly to prevent moisture absorption and caking.
- Keep away from strong acids, strong bases, and active oxidizing materials to avoid harmful reactions.
