  • organic thickeners are fatty acid alkanolamides, polyethylene glycol difatty acid esters and a number of water-soluble polymers.
  • organic thickeners In most cases it is at most possible to use large amounts to adjust the desired viscosity of the surfactant solution by using only inorganic electrolyte salts. It is therefore generally the way to use organic thickeners in addition to the inorganic salts, but some of them have a number of disadvantages.
  • the surfactant solutions thickened with polyethylene glycol fatty acid diesters often have inadequate viscosity stability during storage, while water-soluble polymers have an undesirable slimy flow behavior with a tendency to become stringy in the thickened surfactant solutions.

Abstract

L'invention concerne des sulfates d'ester d'oligoalkylènglycol d'acide gras de la formule (I) R?1COO(R2O)¿nSO3M où M représente un cation, notamment un ion d'ammonium, et R1CO représente un reste acyle avec 6 à 22 atomes de carbone, linéaire ou ramifié, aliphatique, saturé ou non saturé et R2, dans (R2O)n, représente un reste alkylène, notamment CH2CH2, CH(CH3)CH2 ou CH2CH(CH3), n valant alors un nombre de 0,5 à 5, de préférence, de 0,7 à 3, notamment de 0,9 à 2 ou (R2O)n représente une unité du type (EO)u(PO)v(EO)w, E représentant CH2CH2 et P représentant CH(CH3)CH2 ou CH2CH(CH3) et 0≤u≤5, 0,1≤v≤5 et 0≤w≤ 5 ainsi que u + w > 0 et la somme u + v + w représente une valeur de 0,5 à 5, de préférence de 0,7 à 3, notamment de 0,9 à 2. L'utilisation de ces sulfates d'ester d'oligoalkylènglycol d'acide gras, notamment associés à des sulfates d'éther d'alkyle, permet de régler de façon ciblée la viscosité de solutions tensio-actives aqueuses - même sans les épaississants usuels -. Des solutions tensio-actives aqueuses contenant des sulfates d'ester d'oligoalkylènglycol d'acide gras de la formule (I) ont, à température ambiante, des viscosités supérieures à 1000 à 105 mPa.s, de préférence au moins de 5000 mPa.s, notamment au moins de 10000 mPa.s, à savoir au moins de 20000 mPa.s, ou encore des viscosités comprises entre 0,01 et 1000 mPa.s, de préférence entre 0,1 et 600 mPa.s, notamment entre 0,5 et 300 mPa.s, de préférence entre 1 et 100 mPa.s.
