We've recently saw a dog shampoo that had "natural preservative" listed under ingredients.
This same product claimed this preservative was "gentle and based on the natural amino acid glycine".
Following that clue we can presume the preservative is the bottle is sodium hydroxymethylglycinate.
Pet parents, having made the links between paraben preservatives and endocrine disease and formaldehyde based preservatives and cancer risk are beginning to demand safer preservatives in products that go on dogs.
In response, parabens and the traditional formaldehyde releasing compounds like diazolidinyl urea, imidazolidinyl urea, quaternium-15, and DMDM hydantoin (often written as DMDH hydantoin) are being replaced.
Enter a preservative you may not have heard of: Sodium Hydroxymethylglycinate (also called Sodium HMG).
As opposed to the above formaldehyde releasing compounds that slowly release formaldehyde over time, sodium hydroxymethylglycinate only releases small amounts of formaldehyde under certain conditions.
While sodium hydroxymethylglycinate is "safer" than many of the formaldehyde releasing ingredients that over time release formaldehyde and it is "safer" than paraben preservatives, the lack of available research combined with the potential for formaldehyde release (albeit low), and the potential for allergies and skin / eye irritation makes this a preservative we won't be using in 4-Legger products! I guess it is just as well it is not approved for use in USDA certified organic products!
