These three products belong to the PEG-150 distearate series (CAS No.: 9005-08-07). They have stable chemical properties, are non-flammable, and are safe and reliable for humans and the environment under normal use conditions. However, due to their different forms—Thickener 6000DS is a white to off-white powder, Thickener 638 is a slightly yellow transparent liquid, PEG-150 is a white to slightly yellow flake or granule—appropriate protective measures should be taken according to their respective forms during actual operation. In particular, powdery products require special attention to prevent potential risks from dust inhalation and dust accumulation.
All three have the characteristic of slight hygroscopicity, with clear requirements for storage environment temperature and humidity. It is recommended to store at a temperature not exceeding 45°C and relative humidity below 70%, avoiding drastic temperature fluctuations that may cause the product to absorb moisture and agglomerate, affecting its performance. At the same time, they should be kept away from strong acids, strong bases, and active oxidizers to prevent harmful reactions. The unopened product has a shelf life of two years under recommended conditions.

Thickener 6000DS (Powder): Suitable for water-based architectural coatings, water-based adhesives, water-based inks, and textile printing pastes. As a powder, it is convenient for accurate measurement and long-term storage. It is recommended to slowly add it to hot water under stirring conditions for dispersion and dissolution to achieve the best thickening effect. Low dosage can achieve significant anti-settling and anti-splattering capabilities.
Thickener 638 (Liquid): Suitable for latex paints, water-based industrial coatings, water-based adhesives, and water-based inks. Its liquid form makes it easy to disperse, especially suitable for cold blending processes. It can be directly added to the formulation system at room temperature, reducing production energy consumption and process difficulty, and imparting moderate thixotropy to the system.
PEG-150 (Flake/Granule): Widely used in personal care products (shampoos, body washes, creams and lotions) and household industrial detergents. With an HLB value of 18.5, it is easily soluble in water, and its thickening and suspending effects are particularly outstanding in surfactant-containing formulations, improving foam texture and making creams smooth and delicate.
