The present invention relates to particles comprising a core comprising a water soluble flame retardant, such as ammonium polyphosphate and a shell comprising polyphenols, such as lignosulfonates. These particles may be used as flame retardants, in particular in polymer foams. La présente invention concerne des particules comprenant un noyau comprenant un produit ignifuge soluble dans l'eau, tel que le polyphosphate d'ammonium et une enveloppe comprenant des polyphénols, tels que des lignosulfonates. Ces particules peuvent être utilisées comme produits ignifuges, en particulier dans des mousses polymères.
