Abstract
(EN)
The present invention provides a dispersible powder comprising a powder that has been treated using a surface treatment agent. The dispersible powder is characterized by: the surface treatment agent being selected from organopolysilixane surfactants having a weight average molecular weight of 300–20,000; the organopolysilixane surfactants having, as a hydrophilic group, at least one organic group selected from a glycerine group, an amino group, a carboxyl group, and sugar residues; the weight ratio between the hydrophilic group and the total organopolysilixane surfactant being no more than 4.0, when the hydrophilic group is 1; and not having a polyoxyalkylene group. As a result, a dispersible powder can be provided that has excellent dispersibility in aqueous media and oil and high dispersion stability.

La présente invention concerne une poudre dispersible comprenant une poudre qui a été traitée à l'aide d'un agent de traitement de surface. La poudre dispersible est caractérisée en ce que : l'agent de traitement de surface est choisi parmi des tensioactifs d'organopolysilixane ayant un poids moléculaire moyen en poids de 300 à 20 000; les tensioactifs d'organopolysilixane ayant, en tant que groupe hydrophile, au moins un groupe organique choisi parmi un groupe de glycérine, un groupe amino, un groupe carboxyle et des résidus de sucre; le rapport en poids entre le groupe hydrophile et le tensioactif d'organopolysilixane total n'étant pas supérieur à 4,0, lorsque le groupe hydrophile est 1; et n'ayant pas de groupe polyoxyalkylène. Par conséquent, une poudre dispersible peut être fournie qui présente une excellente dispersibilité dans des milieux aqueux et de l'huile et une stabilité de dispersion élevée.
