ABSTRACT:
Clear or translucent fabric softening compositions having a biodegradable fabric softening active and an added chelating agent are disclosed. The biodegradable fabric softening active preferably has the formula:in-line-formulae description="In-line Formulae" end="lead"?[(R)4-m—N(+)—[(CH2)n—Y—R1]m]X(−) (1)in-line-formulae description="In-line Formulae" end="tail"?wherein each R substituent is hydrogen or a short chain C1-C6, preferably C1-C3alkyl or hydroxyalkyl group, e.g., methyl (most preferred), ethyl, propyl, hydroxyethyl, and the like, benzyl, or mixtures thereof; each m is 2 or 3; each n is from 1 to about 4, preferably 2; each Y is —O—(O)C—, —(R)N—(O)C—, —C(O)—N(R)—, or —C(O)—O—, preferably —O—(O)C—; the sum of carbons in each R1, plus one when Y is —O—(O)C— or —(R)N—O)C—, is C6-C22, preferably C12-22, more preferably C14-C20, but no more than one R1or YR1sum being less than about 12 and then the other R1or YR1sum is at least about 16, with each R1being a long chain C5-C21(or C6-C22), preferably C9-C19(or C9-C20), most preferably C11-C17(or C12-C18), straight, branched, unsaturated or polyunsatruated alkyl, the average Iodine Value of the parent fatty acid of the R1being from about 20 to about 140. The chelating agent is preferably diaminetriaminepentaacetic acid. The compositions display excellant clarity with a percentage haze in the transmission mode of a Hunter Color analysis of less than 90%, preferably less than 50%.
