PEG-150 Distearate CAS 9005-08-7

Product identity and physical form

Grade selection and quality controls

Acid and saponification values, water content, color, melting range and physical form help distinguish PEG-150 Distearate grades. Hydroxyl value is useful where included in the specification. These measurements describe different aspects of the ester grade; an active-matter or solids percentage alone does not establish chemical purity or thickening performance.

Viscosity data need the test matrix or solution concentration, temperature, instrument and measuring conditions. A value for heated material is not directly comparable with a dilute aqueous solution or a finished cleanser. In formulation trials, keep surfactant active matter, salts, pH, mixing, cooling and equilibration conditions consistent.

When 1,4-dioxane testing is specified, analytical reports can be provided with the sample matrix, method and reporting limit. ISO 17280:2015 describes gas chromatography for ethoxylated surfactants with 1,4-dioxane above 5 mg/kg; a lower reporting limit requires a suitably validated method for the supplied grade. This is trace-impurity testing, not a GC-purity assay of the polymer.

Formulation use and related raw materials

PEG-150 Distearate helps build viscosity in compatible shampoos, body washes, liquid soaps and other aqueous surfactant systems. Waxy grades generally require controlled heating or pre-dissolution. Use the melting or dispersion procedure in the grade TDS and assess the addition sequence, mixing and cooling in the complete formulation. Ambient-temperature processing may use a pre-dissolved preparation; it does not imply that the solid dissolves rapidly in cold water.

Evaluate thickening in the complete cleansing base, including any Sodium Laureth Sulfate (SLES) or Cocamidopropyl Betaine Powder. Powder grades require their own dissolution procedure and an active-matter comparison. Changes in salts, pH and surfactant composition can change viscosity, clarity and stability.

PEG-120 Methyl Glucose Dioleate is a structurally different nonionic thickener for formulation comparison. Cocamide MEA (CMEA) is an alkanolamide option for foam and rheology control. Their composition and processing differ from PEG-150 Distearate, so substitution or combination requires formulation trials rather than a one-to-one exchange.

Handling and quotations

Keep the product dry and the packaging closed, and protect it from contamination and excessive heat. The grade TDS gives storage and charging conditions; the SDS covers dust or hot-melt handling, exposure controls, spill response and transport. The selected grade and finished formulation must suit the intended application and destination market.

For a quotation, send the required quantity, destination and intended surfactant application or reference grade. A target viscosity and its test conditions help match the product and processing requirements.
