Patent

CA 2707090

A shelf-stable, liquid whitening composition having a whitening agent and a stabilizing system are disclosed. The stabilizing system includes a gum component, preferably of a mixture of two different gum, present in an amount sufficient to suspend the whitening agent in the liquid whitening composition and in an aqueous media to which the liquid whitening composition is added, an emulsifier in an amount sufficient to maintain emulsion stability in the liquid whitening composition and in the aqueous media, and a cellulose component, preferably of a blend of a microcrystalline cellulose and carboxymethylcellulose blend, in an amount sufficient to help maintain suspension and emulsion stability of the liquid whitening composition alone and in the aqueous media. The stabilizing system maintains the liquid whitener in a homogeneous state for at least about 9 months at ambient temperatures, and further maintains the whitening composition in suspension when added to the aqueous media.

L'invention concerne une composition blanchissante liquide à longue durée de conservation comprenant un agent blanchissant et un système stabilisateur. Le système stabilisateur comprend: un constituant gomme, de préférence issu d'un mélange de deux gommes différentes dont la quantité est suffisante pour transformer en suspension l'agent blanchissant dans la composition blanchissante liquide et dans un milieu aqueux auquel la composition blanchissante liquide est ajoutée; un émulsifiant dont la quantité est suffisante pour maintenir une stabilité d'émulsion dans la composition blanchissante liquide et dans le milieu aqueux; et un constituant cellulose, de préférence issu d'un mélange de cellulose microcristalline et de carboxyméthylcellulose, dont la quantité est suffisante pour maintenir la stabilité en suspension et en émulsion dans la composition blanchissante liquide seule et dans le milieu aqueux. Le système stabilisateur maintient l'agent blanchissant liquide dans un état homogène pendant au moins 9 mois à des températures ambiantes; il maintient en outre la composition blanchissante liquide en suspension lorsqu'il est ajouté au milieu aqueux.
