  • Is AEO-9 (C12-14 E9) good for body wash and hand soap?

    I bought some generic AEO-9 (fatty alcohol ethoxylate; C12-C14 alcohol with 9 EO) for dish soap experiments. Now that I have it, I find it’s reasonably easy to use as well as cheap when I buy in sample quantities.

    Is it good to use on skin compared to common personal care detergents like lauryl sulfates, SLES, CAPB, and the glucosides? Is there anything I should worry about, such as eye irritancy? Obviously I need to try it to see whether it’s too drying or has another obvious detrimental effect, but it would be helpful to know what you guys think about alcohol ethoxylates on skin.

    I would probably be using it in a foaming hand soap that’s 2% active SLS, 1.75% active nonionic surfactants, 0.75% active CAPB, and small amounts of salt, glycerin, and preservative. The body wash would be a standard sulfate-based body wash with CAPB, but with perhaps a third of the ALS, SLES, or both replaced with AEO-9. The exact amount would depend on foam, feel, salt thickening, etc.
