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.
