What is Sodium Hydroxymethylglycinate?

Sodium Hydroxymethylglycinate - it doesn't exactly trip off the tongue!

It is a chemical preservative commonly used in "natural" beauty products to help preserve them from bacterial or fungal growth.

We are meeting more and more people who have extremely strong reactions to products containing this chemical.

One customer used an organic facial moisturiser from a well know 'natural' skincare brand and immediately had an intense burning sensation followed by extreme irritation lasting for several days.

Sodium Hydroxymethylglycinate is a skin irritant in high concentrations, and should only used in low levels in products - 0.1%. Although there are products out there using higher concentrations.

It is far more of an irritant than Parabens and it affects more people. Parabens have been used for years and there are few reported cases of Paraben allergies.

But many manufacturers are shifting away from Parabens because of the bad press and instead including less well known chemicals to preserve their products.

Sodium Hydroxmethylglycinate is often described as "organic" or naturally derived from the glycine, an amino acid.

However, there is little that is organic about it - it goes through a rigorous manufacturing process using lots of chemicals. Indeed, one of the particular problems highlighted is that Sodium Hydroxymethylglycinate is sometimes contaminated with Formaldehyde, which is used during manufacture.

It is also thought to break down into Formaldehyde in the body - which is a problem if the product you are using is a moisturiser, designed to permeate the skin. It is less of a concern if it is present in a shampoo or cleanser, which is washed off.

Many people come to organic skin care after developing reactions to chemicals in their usual products. Unfortunately, if you purchase a product containing Sodium Hydroxmethylglycinate, there is a chance it will irritate your skin or that you will have an allergy to it.

At Pai Skincare, we only use natural preservatives - no Parabens and certainly no Sodium Hydroxymethylglycinate.
