Frequently Asked Questions

What is PEG-40 sorbitan diisostearate?

PEG-40 sorbitan diisostearate (CAS 70209-99-3) is a nonionic surfactant — the PEG (40 EO) sorbitan diester of isostearic acid. It is used as an emulsifier and surfactant in cosmetic and personal-care formulations.

What is PEG-40 sorbitan diisostearate used for?

It functions as an oil-in-water emulsifier for oil-containing formulations, as a nonionic surface-active agent, and as a solubilizer that disperses oils and lipophilic ingredients.

Is PEG-40 sorbitan diisostearate the same as castor oil?

No. PEG-40 sorbitan diisostearate is a sorbitan/isostearic-acid ester ethoxylated with about 40 EO (CAS 70209-99-3) and is unrelated to castor oil or to PEG-40 hydrogenated castor oil, which is a different chemistry built on a castor-oil base.

What is the HS code and CAS for PEG-40 sorbitan diisostearate?

CAS 70209-99-3, HS code 3402.42 (non-ionic organic surface-active agents). CoA and SDS accompany each RawSource lot; confirm the destination tariff line with your customs broker before import.

What is the cost of bulk PEG-40 sorbitan diisostearate?

Bulk pricing varies with volume, packaging and destination. Request a quote from RawSource with your target quantity and ship-to location for current landed pricing.
