Estimating the term…
A conditioning composition is used in functional systems (personal care and household care compositions) that has a nonionic hydrophobically modified cellulose ether (HMCE) having a weight average molecular weight (Mw) with a lower limit of 400,000 and an upper limit of 2,000,000 and a hydrophobic substitution lower limit of 0.6 wt % and an upper limit amount which renders said cellulose ether insoluble in a 5 wt % solution of surfactant and less than 0.05% by weight soluble in water and wherein the cellulose ether provides conditioning benefit to the functional system substrate. This composition has at least one active functional system ingredient.
A conditioning composition comprising
A process of conditioning an aqueous based functional system selected from the group consisting of personal care and household care products comprising adding and mixing a sufficient amount of a hydrophobically modified cellulose ether that is compatible with the aqueous based functional system to thicken the functional system wherein the hydrophobically modified cellulose ether is a nonionic hydrophobically modified cellulose ether (HMCE) polymer having a weight average molecular weight (Mw) with a lower limit of 400,000 and an upper limit of 2,000,000 and a hydrophobic substitution lower limit of 0.6 wt % and an upper limit amount which renders said cellulose ether insoluble in a 5 wt % solution of surfactant and less than 0.05% by weight soluble in water and wherein the cellulose ether provides conditioning benefit to a functional system substrate, and the resulting functional system has comparable or better conditioning properties as compared to when using similar thickening agents outside the scope of the present composition.
