Abstract

L'invention concerne une composition de lessive liquide pour linge qui comprend ５% en masse ou plus à ３０% en masse ou moins d'un tensio-actif (a), et une eau. η０,１／η１００ qui constitue le rapport entre la viscosité (η０,１) à une vitesse de cisaillement de ０,１Ｓ－１ à 30°C et la viscosité (η１００) à une vitesse de cisaillement de １００Ｓ－１ à 30°C, est supérieur ou égal à １,５ et inférieur ou égal à ３０. Ｇ'１００／Ｇ''１００ qui constitue le rapport entre le module d'élasticité de conservation (Ｇ'１００) et le module de perte (Ｇ''１００) à une pulsation de １００ｒａｄ／ｓ, est supérieur ou égal à 1. Ｇ'１,０／Ｇ''１,０ qui constitue le rapport entre le module d'élasticité de conservation (Ｇ'１,０) et le module de perte (Ｇ''１,０) à une pulsation de １,０ｒａｄ／ｓ, est inférieur à 1.
