Sodium Hydroxymethylglycinate is a broad spectrum antimicrobial that is active against Gram-negative and Gram-positive bacteria, yeast and mold. It is used at extremely low concentrations between .1% to 1% at the most. It is active at all alkaline pH levels as well as acidic conditions. It acts for both preservation and neutralization, which means it can be used in place of TEA (Triethanolamine) or Sodium hydroxide. It is synergistic with other Preservatives. There are no ingredients used in cosmetics that render sodium hydroxymethylglycinate non-effective. Sodium hydroxymethylgycinate is derived from glycine, which is a naturally occurring amino acid. Traditionally glycine was used a texturizer in cosmetics. It is an amino acid classified as nonessential. Glycine is made up of sweet-tasting crystals, it is used as a dietary supplement and as a gastric Antacid. Amino Acids are widely used in cosmetics because they help penetrate the skin. This preservative can react with certain Essential Oils, specifically citrus and mint oriented. The reaction can cause your product base to change colors, but does not effect the effacacy of the preservative. Sodium hydroxymethylglycinate in aqueous solution decomposes to sodium glycinate and Formaldehyde. Glycine is an essential amino acid, and does not appear to be harmful. So, the regulation of sodium hydroxymethylglycinate as total Formaldehyde should not give any additional safety problem to consumers, as long as the maximum authorized concentration of this compound is maintained.

***********************************************************clara ha scritto:Su off. naturae dicono:
Sodium Hydroxymethylglicinate conservante liberatore di Formaldeide. pessima
Anche lui da aggiungere al Bio-diz vedo che c'è in vari cosmetici.
Grazie per la segnalazione Clara ;-)
l'ho visto spesso..ma non riuscivo a trovarlo..
ora so che è pessimo.. :-/
aggiungo alla lista...

Re: Hydroxymethylglicinate
Qualcuno sa dirmi un po' di più di questo ingrediente?
L'ho trovato in un gel d'Aloe.
L'INCI è:
Aloe Barbadensis 98%
Sodium Carbomer (anche questo non so che sia)
Disodium EDTA
Potassium Sorbate
Methylparaben
Sodium Hydroxymethylglycinate
è da buttare???

Re: Hydroxymethylglicinate
Cara Eccia,
oltre al liberatore di formaldeide questo prodotto contiene anche:
Sodium Carbomer (anche questo non so che sia) è una resina sintetica che serve per gelificare il prodotto. Completamente sintetico.
Disodium EDTA: mobilizza i metalli pesanti dai depositi marini, pessimo.
Insomma il tuo prodotto è prprio una schifezza. C'è di meglio.

Re: Hydroxymethylglicinate
Missione compiuta, il Hydroxymethylglicinate è nel biodizionario (con un doppio rosso).
Re: Hydroxymethylglicinate
Grazie Fabrizio... ma che tristezza...
E' proprio da buttare o c'è qualcuno che mi possa suggerire qualche utilizzo? Mi dispiace buttarlo...
