Nonionic Surfactants

Emulsifier EL-40 (PEG-40 Castor Oil)

Emulsifier EL-40 is PEG-40 castor oil - a nonionic surfactant made by ethoxylating castor oil with 40 moles of ethylene oxide (HLB 13-14, 1% cloud point 70-84 degC, pH 5.0-7.0, moisture <=1.0%). It is a light-yellow oily or creamy substance soluble in most organic solvents and dispersible in water, with strong emulsifying and diffusing action for textile, cosmetic and industrial systems.

Frequently asked questions

What makes Emulsifier EL-40 different from a typical PEG emulsifier?

EL-40 is PEG-40 castor oil, castor oil ethoxylated with 40 moles of ethylene oxide, so it carries the ricinoleic backbone of castor oil rather than a straight-chain fatty alcohol. That gives it strong solvency in organic solvents while staying dispersible in water, which is why it shows up in both cosmetic emulsions and pharmaceutical solubiliser roles. The published form is a light-yellow oily or creamy substance.

What HLB and cloud point should I design around with EL-40?

It is specified at HLB 13-14 with a 1% cloud point of 70-84°C and 1% pH 5.0-7.0, moisture ≤1.0%. That HLB range is a classic oil-in-water emulsifier window, and the cloud point tells you it stays in solution through most hot-process steps. We recommend a sample to confirm the exact emulsion type in your oil phase.

Is EL-40 suitable as a pharmaceutical solubiliser, and what documentation do you provide?

Pharmaceutical solubiliser and carrier use is listed among its applications, but no pharma-grade certificate is in the published specification. For drug-product or topical work, request the applicable grade certificate and a lot COA so your QA can sign off before use.

What backs up the EL-40 specification values?

CAS 61791-12-6 and the spec block (HLB, cloud point, moisture) are cross-checked across two consistent client records: the original product page and the client manual's ethoxylated castor oil EL-10-EL-90 series. We recommend a lot-specific COA for incoming QC.

How do I handle EL-40 on the line?

It is a light-yellow oily or creamy substance at 25°C, soluble in most organic solvents and dispersible in water. Heating or pumping characteristics at elevated temperature are not in the published data, so confirm compatibility with your process equipment and request the TDS for any temperature-dependent handling points.
