Abstract:
1. A post-foaming cleansing composition comprising at least one anionic surfactant together with at least one amphoteric surfactant, said amphoteric surfactant constituting from 0.5% to 3.0% by weight of the total composition, at least one non-ionic gelling agent and at least one post-foaming agent, characterised in that the ratio of anionic surfactant:non-ionic gelling agent is 4:1 or greater such that during manufacture the rigidity of the composition always remains substantially unchanged for at least 4 minutes after addition of the said post-foaming agent to the remainder of the composition, wherein the non-ionic gelling agent is selected from alkoxylated alcohols laureth-2, laureth-4, C12/13 pareth-3, ceteareth-4, or oleth-3 alone or in combination, and wherein the at least one non-ionic gelling agent constitutes from 0.5% to 2.5% by weight of the total composition, wherein the composition is filled into a package from which the subsequently formed gel is dispensed, wherein the composition is filled into the package prior to the gel structure being formed, wherein the foregoing steps are performed absent any applied elevated pressure; and wherein the package is selected from the group comprising a bag on valve container, a bag in can container and an elasticated bladder container, wherein the rigidity of the composition remains substantially unchanged for the at least 4 minutes and in accordance with a gel rigidity rating scale of: R=1 Rigid gel with no visible mobility, Gel retains its shape until the post-foaming agent starts to be released and the gel starts to turn into a foam; R=2 Firm gel with some visible mobility Gel starts to form into an amorphous mound before the post-foaming agent starts to be released and the gel starts to turn into a foam; R=3 Firm gel with some visible mobility which collapses slowly Gel forms an amorphous mound on dispensing which slowly spreads; R=4 Thin gel/mobile liquid Gel has viscous appearance but spreads rapidly after dispensing; R=5 Thin liquid Gel has a non-viscous appearance and is runny after dispensing; and wherein the rigidity of the composition remains substantially unchanged for the at least four minutes at a gel rigidity rating of at least R4 after the addition of said post-forming agent to the mixture, and then after said at least four minutes transitions to a rigidity rating of R1 or R2.
