Laureth-23
CAS No. 68551-12-2

 

Laureth-23 is a high HLB emulsifier used in oil-in-water emulsions. Laureth-23 finds use in cosmetic and pharmaceutical products as a surfactant, emulsifier and solubilizer.  It is particularly useful in some formulations in light of its chemical inertness to hydrolytic decomposition

Laureth-23 is a nonionic surfactant prepared from lauryl alcohol and 23 moles of ethylene oxide. Laureth-23 contains an average of 23 repeating ethylene oxide units.  Small amounts of 1,4-dioxane, a by-product of ethoxylation, may be found in Laureth-23. The potential presence of this material is well known and can be controlled through purification steps to remove it.  Our product has been purified and contains no 1,4-dioxane (0 ppm).

The Cosmetic Ingredient Review has reviewed this ingredient and it is declared safe as used up to 6%.

Formulation Guidelines

While soluble in water, like most emulsifiers, it should be added to the oil phase of your formulation and heated past the melt point of the highest melt point material.  Oil and water phases should be combined at the same temperature.

We've had a ferry breakdown at the Orcas Island dock today (Monday) and this has affected the ability for UPS shipments to leave the island in time to make the connection with UPS departures on the mainland. Expect a ONE day delay on UPS shipments departing Lotioncrafter today. This is an unavoidable delay outside the UPS system. We will update later today.

Our Customers Say...
Hi, I just wanted to express how happy I am with Lotioncrafter. I have ordered from them three times and this last time I mistakenly put through the wrong shipping address in my order. I called and spoke to Jen and she corrected it immediately. I was very pleased with her efficiency that I had to come in write my own testimonial, something I don't usually do.

The last 2 orders arrived in a timely fashion but this one has taken a little longer because of the memorial day weekend. I knew it was going to be shipped late because on the site, they let the customers know that shipping would be delayed as a result of the holiday. I was very happy with this as well - at least I knew about the possible delay ahead of time.

Thanks Jen for always providing stellar customer service.
