Solid cleansing composition presenting controlled disintegration
A solid cleansing composition comprising a (I) first and a (II) second phase; wherein the (I) first phase comprises a mixture of ingredients including (a) a solid surfactant, (b) a disintegration agent and (c) a lubricant; the (2) second phase comprising (d) a superabsorbent polymer and (e) a binder.
1 . A multilayered, single use, solid cleanser personal care product consisting essentially of a solid cleansing composition comprising a (I) first phase and a (II) second phase; wherein the (I) first phase comprises a mixture of ingredients including (a) a solid surfactant, (b) a disintegration agent comprising pregelatinized starch, and (c) a lubricant comprising magnesium stearate; the (2) second phase comprising (d) a superabsorbent polymer selected from the group consisting of starch-grafted superabsorbent polymers and/or mixtures thereof, and (e) a binder comprising water, and wherein the (I) first and (II) second phases are arranged in layers adjacently to each other and wherein the multilayered, single use, solid cleanser personal care product disintegrates during use.
2 . The personal care product of claim 1 wherein the (a) solid surfactant is selected from Disodium Lauryl Sulfosuccinate, sodium lauryl sulfate, sodium cocoyl isethionate or their mixtures.
3 . The personal care product of claim 1 wherein the (I) first phase is divided in, at least, two layers; wherein the second phase is sandwiched between two layers of the first phase.
4 . The personal care product of claim 1 wherein the second phase is divided in, at least, two layers; wherein the first phase is sandwiched between two layers of the second phase.
5 . The personal care product of claim 1 wherein the (I) first phase includes from about 50 wt-% to about 90 wt-% of disintegrant, from about 7 wt-% to about 47 wt-% of surfactant, and the lubricant is present in an amount of less than about 5 wt-%.
6 . The personal care product of claim 1 wherein the (I) first phase includes from about 60 wt-% to about 80 wt-% of disintegrant, from about 17 wt-% to about 37 wt-% of surfactant, and about 2 wt-% to about 5 wt-% of lubricant.
7 . The personal care product of claim 1 wherein the (I) first phase includes about 70 wt-% of disintegrant, 27 wt-% of surfactant, and 3 wt-% of lubricant.
8 . The personal care product of claim 1 wherein the mass ratio between the (I) first and (II) second phases is about 1:1.
