A process for making substantially anhydrous surfactant compositions which, at room temperature, are shear thinning non-Newtonian pastes with a yield point that allows them to be easily worked in commercial apparatus. The process employs hydrotropes, anionic surfactants and nonionic surfactants in a drying step to provide the pastes. The pastes are especially suitable for incorporation into anhydrous liquid detergent products.
L'invention concerne un procédé de production de compositions de tensioactifs sensiblement anhydres qui, à température ambiante, se présentent sous forme de crèmes présentant une fluidification non newtonienne avec une limite apparente d'élasticité qui leur permet d'être facilement utilisées dans un appareil commercial. Pour la production de ces crèmes, ledit procédé utilise des hydrotropes, des tensioactifs anioniques et non ioniques dans une étape de séchage. Ces crèmes sont particulièrement appropriées à une addition à des produits détergents liquides anhydres.
