Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 215 words
A stable, aqueous, pourable and water dispersible fabric conditioning composition which is biodegradable and capable of providing fabric softening concomitant with significant reduction and solubilization of unwanted mineral encrustations on fabrics to be conditioned, such encrustations having been generally deposited on the fabrics during the course of prior laundering in water having a high mineral content, which conditioning composition comprises, by weight, of (a) 1% to 25% of an acid complex of: (i) as the sole softening component a fabric softening effective amount of a softening compound of formula (I): ##STR7## wherein R1 is C12 to C30 alkyl or alkenyl, R2=R1CONH(CH2)m, R3=(CH2CHO)pH, CH3 or H, n=1 to 5, m=1 to 5, p=1 to 10; and (ii) unreacted inorganic acid, wherein said acid complex is formed by the reaction of said fabric softening compound with said inorganic acid in a mole ratio of inorganic acid to fabric softening compound of from about 0.5:1 to about 5:1, the amount of acid being sufficient to prevent the fabric conditioning composition from forming a gelled structure, but less than an amount which adversely affects the physical stability of said fabric conditioning composition; (b) 1% to 25% of a C2-C6 carboxylic acid in an amount effective for removing encrustation from the fabrics to be conditioned; and (c) an aqueous solvent.
Claim 2
Dependent Claim 215 words
A stable, aqueous, pourable and water dispersible fabric conditioning composition which is biodegradable and capable of providing fabric softening concomitant with significant reduction and solubilization of unwanted mineral encrustations on fabrics to be conditioned, such encrustations having been generally deposited on the fabrics during the course of prior laundering in water having a high mineral content, which conditioning composition comprises, by weight, of (a) 1% to 25% of an acid complex of: (i) as the sole softening component a fabric softening effective amount of a softening compound of formula (I): ##STR7## wherein R1 is C12 to C30 alkyl or alkenyl, R2=R1CONH(CH2)m, R3=(CH2CHO)pH, CH3 or H, n=1 to 5, m=1 to 5, p=1 to 10; and (ii) unreacted inorganic acid, wherein said acid complex is formed by the reaction of said fabric softening compound with said inorganic acid in a mole ratio of inorganic acid to fabric softening compound of from about 0.5:1 to about 5:1, the amount of acid being sufficient to prevent the fabric conditioning composition from forming a gelled structure, but less than an amount which adversely affects the physical stability of said fabric conditioning composition; (b) 1% to 25% of a C2-C6 carboxylic acid in an amount effective for removing encrustation from the fabrics to be conditioned; and (c) an aqueous solvent.
Claim 3
Dependent Claim 51 words
