Steareth-21 CAS 9005-00-9

Steareth-21 is a nonionic ethoxylated fatty alcohol derivative typically used as an emulsifier and formulation aid in emulsion-based systems. In supplier practice, it is generally positioned as a formulation ingredient rather than a single pure compound. It is commonly selected for cream, lotion, and related liquid or semi-solid formulations where stable oil-in-water emulsification and formulation compatibility are required. Supply can be arranged in standard export packaging, with document support such as COA, TDS, and SDS available according to customer and order requirements.

Specific end uses should be evaluated according to local regulatory requirements and actual formulation conditions.

Packaging

Steareth-21 is generally supplied in sealed containers suitable for solid or semi-solid surfactant materials. Standard export packaging can be arranged according to order quantity, supply form, and logistics requirements. Clean container handling and proper sealing are recommended to help protect the material during storage and transport.

Storage

Store in a cool, dry, and well-ventilated place in tightly closed original packaging. Keep away from excessive heat, direct sunlight, and sources of contamination. Package integrity should be maintained during storage and transportation. Where the material softens under elevated temperature, containers should be kept properly closed and handled in a clean environment.

FAQ

1. What kind of product is Steareth-21?

Steareth-21 is a nonionic emulsifier and formulation ingredient commonly used in emulsion-based systems.

2. Is Steareth-21 a single pure compound?

In normal commercial supply, it is generally treated as an ethoxylated formulation raw material rather than a simple single-molecule product.

3. What are the typical use directions for Steareth-21?

It is commonly used in cream, lotion, and related oil-in-water emulsion formulations as an emulsifying component.

4. What packaging can be provided?

Standard export packaging can be arranged based on supply form and order quantity.

5. What documents are usually available?

COA, TDS, and SDS can usually be provided according to supply requirements.

6. Is sample supply available?

Sample availability can be discussed based on grade, stock status, and project requirements.
