Frequently Asked Questions
What is C12-13 Pareth-3?
C12-13 Pareth-3 (CAS 66455-14-9) is a nonionic surfactant — a polyethylene-glycol ether of C12-13 fatty alcohols carrying an average of 3 ethylene-oxide units. Alcohol ethoxylates of this type function as surfactants, emulsifiers, and wetting agents in cleaning and personal-care formulations.
Is C12-13 Pareth-3 the same as Sodium C12-13 Pareth Sulfate?
No. C12-13 Pareth-3 is the nonionic ethoxylated fatty-alcohol ether itself. Sodium C12-13 Pareth Sulfate is the anionic sulfate ester made by sulfating an ethoxylated C12-13 alcohol and neutralizing with sodium — a different material with a different INCI name and CAS.
What is C12-13 Pareth-3 used for?
It is used as a nonionic surfactant, emulsifier/co-emulsifier for oil-in-water systems, and wetting/spreading aid in cleaning and personal-care formulations. The low ethoxylation degree (~3 EO) makes it relatively oil-compatible compared with higher-EO grades.
Does RawSource supply C12-13 Pareth-3 in bulk packaging?
Yes. RawSource distributes industrial surfactants in bulk formats such as drums, IBC totes, and tankers to manufacturers. Contact us with your target volume and we will quote available pack sizes and lead time.
Can RawSource provide a CoA and SDS for C12-13 Pareth-3?
Yes. A Certificate of Analysis and Safety Data Sheet are provided with shipments. Request current documentation against CAS 66455-14-9 when you submit an RFQ.
What is the REACH and TSCA regulatory status of C12-13 Pareth-3?
C12-13 Pareth-3 (CAS 66455-14-9) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 500-165-3).
