Abstract:
A softening system which comprises:(a) a water soluble container which is formed from a 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; and (b) a liquid fabric softener composition disposed in said water soluble container, wherein said fabric softener composition comprises 25% to 65% of at least one softening compound which is an amido-amine softening agent â€ƒWherein R1 and R2 are each independently long chain alkyl or alkenyl groups having 8 to 22 carbon atoms, R3 is selected from the group consisting of (CH2CH2O)pH, CH3 and H and mixtures thereof, p is an integer from 1 to 10 and m and n are integers from 1 to 5; and (c) 0.5 wt % to 10 wt % of at least one dispersing aid selected from the group consisting of glycereth cocoate, oleate PEG200, dioleate PEG400, and a C12-C13EO3:1 ethoxylated fatty alcohol and mixtures thereof and wherein the compositions do not contain a detergent builder salt, a silicone glycol copolymer, a green colorant, a yellow colorant or a poly(oxyalkylene) substrated colorant.
