All you need to know: ‘Prohibited use of Pentasodium Pentetate in M&P bases’

< Back

If you’re in the soap business, you may already be aware of the reclassification of chelate Pentasodium Pentetate, an ingredient found in over 400 personal care and cosmetic products.

As of December 1st 2023, the use of Pentasodium Pentetate in soap and cosmetic products manufactured in the EU will be prohibited.

We’ve been asked by a number of customers about these changes, so here’s a whistle-stop tour on what the reclassification means to you and your business.

What is Pentasoldium Pentetate?

Pentasodium Pentetate is a chelating agent used in soaps and cosmetic products to prevent various mineral components from binding together and negatively affecting the formulation. Chelates are used to prevent rancidity, brown-spotting, cracking and discolouration.

How will this affect my business?

In a nutshell, it won’t. We work hand-in-hand with leading personal care manufacturer, Stephenson which has already removed Pentasodium Pentetate from the full range of Melt & Pour products we distribute.

Why has it been removed already?

Whilst there was no immediate need to remove the material, being ahead of the curve is our priority here at O&3 to ensure we are at the forefront of important and necessary legislation within the industry.

What has replaced Pentasodium Pentetate?

A plant derived chelate, known as Tetrasodium Iminodisuccinate has replaced it. This ingredient has all the benefits of Pentasodium Pentetate, which means there is no change to the products stability or performance.

The move to Tetrasodium Iminodisuccinate was made in August 2022 and as of November 2022, Pentasodium Pentetate has been removed from all product ranges manufactured by Stephenson.

Our mission to provide the best soap solutions for our customers

Our vast range of sustainably sourced, raw oils perfectly compliment the Melt & Pour range manufactured by Stephenson, so collaborating with the leaders in personal care and cosmetics was a natural choice for O&3.

We love working with Stephenson and being part of our customers’ soap journeys, exploring together the different oils used to add extra indulgence or fragrance to many different soap products.
