Title
(EN) HIGH-DENSITY DETERGENT COMPOSITION
(FR) COMPOSITION DE DETERGENT HAUTE DENSITE
Abstract
(EN)
A high-density detergent composition which has excellent detergency even when used in a washing machine operated at a low power, and which is excellent not only in particle solubility and dispersibility but in solubility in laundering by hand. The composition contains 10 to 60 wt.% surfactant composition comprising an anionic surfactant and a nonionic surfactant in a ratio of 4/10 to 10/0 by weight and has a bulk density of 600 to 1,200 g/L. It satisfies the relationship S(Wi.Vi)=95 (%), wherein Wi is the weight frequency of each of the groups of particles obtained by classifying the detergent particles with a classifier comprising sieves respectively having opening sizes of 2,000, 1,410, 1,000, 710, 500, 355, 250, 180, and 125 $g(m)m and receiver pans and Vi is the solubility of each group of particles as determined under the following measurement conditions. The weight frequency of the group of particles smaller than 125 $g(m)m is 0.1 or lower. [Measurement conditions: 1.000±0.010 g of a sample is added to 1.00±0.03 L of water having a temperature of 5±0.5°C and a hardness of 4° DH. The mixture is stirred in a 1-L beaker for 120 seconds at a rotational speed of 800 rpm. The residual particles are taken out by filtration with a standard sieve provided for in JIS Z 8801.]
(FR)
L'invention concerne une composition de détergent haute densité qui présente une excellente détergence, même lorsqu'on l'utilise dans une machine à laver fonctionnant à faible puissance, et qui possède non seulement d'excellentes propriétés de solubilité et de dispersibilité des particules, mais aussi une excellente solubilité lors de lavage à la main. La composition contient de 10 à 60 % en poids d'une composition de tensioactif renfermant un tensioactif anionique et un tensioactif non ionique selon un rapport se situant entre 4/10 et 10/0 en poids, et présente une masse volumique en vrac se situant entre 600 et 1200 g/l. La composition est conforme à la relation S(Wi x Vi)=95 (%), Wi étant la fréquence de poids de chacun des groupes de particules obtenus par la classification des particules de détergent à l'aide d'un classificateur comprenant des tamis présentant respectivement des dimensions d'ouvertures de 2000, 1410, 1000, 710, 500, 355, 250, 180, et 125 $g(m)m ainsi que des bacs collecteurs ; et Vi étant la solubilité de chaque groupe de particules déterminée selon les conditions de mesure suivantes : la fréquence de poids du groupe de particules inférieures à 125 $g(m)m est égale ou inférieure à 0,1. [Conditions de mesure: on ajoute 1,000±0,010 g d'un échantillon à 1,00±0 ,03 l d'eau présentant une température de 5±0,5 °C et une dureté de 4° DH. Le mélange est agité dans un bécher d'un litre pendant 120 secondes à une vitesse de rotation de 800 rpm. Les particules résiduelles sont extraites par filtration à l'aide d'un tamis standard prévu dans JIS Z 8801].
