Frequently asked questions

Is Tween-80 certified for food or pharmaceutical use?

Tween-80 conforms to the Chinese chemical industry standard HG/T 3510. Food-grade or pharmaceutical-grade certification is not part of the published specification data; for regulated use, please request the applicable grade certificate so your quality team can confirm suitability before use.

How reliable is the specification data?

The identity (CAS 9005-65-6) and specification block are cross-checked across two consistent client records — the product manual (p55) and the CAS reference document (p7, Tween series). We recommend requesting a lot-specific COA for incoming quality control.

How is the amber viscous grease handled in production?

The product is an amber viscous grease at 25°C. Please confirm pumping and heating compatibility with your process equipment, as handling characteristics at elevated temperature are not specified in the published data.
