Abstract:
A softening system which comprises:(a) a water soluble container which is formed from water soluble polymer which is selected from the group consisting of polyvinyl alcohols, polyvinyl alcohol copolymers such as polyvinyl alcohol/polyvinyl pyrrolidone, partially hydrolyzed polyvinyl acetate, polyvinyl pyrrolidone, alkyl celluloses such as methyl cellulose, ethyl cellulose and propyl cellulose, ethers and esters of alkyl celluloses of alkyl celluloses, hydroxy ethyl cellulose, hydroxy propyl cellulose, carboxy methyl cellulose sodium, dextrin, maltodextrin, such as methyl cellulose, ethyl cellulose and propyl cellulose, water soluble polyacrylates, water soluble polyacrylamides and acrylic acid/maleic anhydride copolymers; (b) a fabric softener composition disposed in said water soluble container, wherein said fabric softener composition comprises approximately by weight: (i) 87% to 98% of a clay based mineral softener which is a montmorillonite containing clay having a smectite structure and having 5 wt. % to 18 wt. % of moisture in combination with an organic softener selected from the group consisting of polyol polymers, fatty alcohols, monopentaerythriol esters, dipentaerythritol esters, pentaerythritol 10 ethylene oxide ester, and pentaerythritol 4 propylene oxide esters and mixtures thereof; and (ii) 1% to 10% of a perfume, wherein the composition contains less than 3.0 wt. % of water.
