Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
An article of manufacture adapted for use in an automatic dryer, comprising: (a) a fabric treating composition consisting essentially of (i) a static-controlling amount of a hygroscopic surfactant of the formula R--O--(C.sub.2 H.sub.4 O).sub.x --C.sub.2 H.sub.4 OH wherein R is selected from the group consisting of primary, secondary and branched chain alkyl hydrocarbyl moieties; primary, secondary and branched chain alkenyl hydrocarbyl moieties; and primary, secondary and branched chain alkyl- and alkenyl-substituted phenolic hydrocarbyl moieties; said hydrocarbyl moieties having a hydrocarbyl chain length of from about 10 to about 18, and wherein x is an integer of from about 35 to about 50, and (ii) a softening amount of a fabric softener consisting essentially of a transesterified mixture of fatty glycerides containing from about 20% to less than about 30% by weight of soap and having a melting point above about 40° C. and a fatty alcohol having about 10 to about 20 carbon atoms at a weight ratio of glycerides:alcohol of from about 7:3 to about 9:1; and (b) a flexible substrate in releasable combination with said fabric treating composition.
Claim 2
Dependent Claim

An article of manufacture adapted for use in an automatic dryer, comprising: (a) a fabric treating composition consisting essentially of (i) a static-controlling amount of a hygroscopic surfactant of the formula R--O--(C.sub.2 H.sub.4 O).sub.x --C.sub.2 H.sub.4 OH wherein R is selected from the group consisting of primary, secondary and branched chain alkyl hydrocarbyl moieties; primary, secondary and branched chain alkenyl hydrocarbyl moieties; and primary, secondary and branched chain alkyl- and alkenyl-substituted phenolic hydrocarbyl moieties; said hydrocarbyl moieties having a hydrocarbyl chain length of from about 10 to about 18, and wherein x is an integer of from about 35 to about 50, and (ii) a softening amount of a fabric softener consisting essentially of a transesterified mixture of fatty glycerides containing from about 20% to less than about 30% by weight of soap and having a melting point above about 40° C. and a fatty alcohol having about 10 to about 20 carbon atoms at a weight ratio of glycerides:alcohol of from about 7:3 to about 9:1; and (b) a flexible substrate in releasable combination with said fabric treating composition.
Claim 3
Dependent Claim
25 words
An article according to claim 1 wherein the anti-static agent is selected from the group consisting of coconutalkyl EO(45), tallowalkyl EO(45), and lauryl alcohol EO(45).
Claim 4
Dependent Claim
23 words
An article according to claim 2 wherein the fabric softener comprises the trans-esterified reaction product of hardened tallow fat, glycerine and sodium hydroxide.
Claim 5
Dependent Claim
23 words
An article according to claim 2 wherein the fabric softener comprises the trans-esterified reaction product of hardened soybean oil, glycerine and sodium hydroxide.
Claim 6
Dependent Claim
158 words
An article according to claim 1, consisting essentially of: (a) a fabric treating composition consisting essentially of: (i) from about 1 gram to about 3 grams of a glyceride mixture consisting essentially of the trans-esterified glyceride reaction product of a 3:2.6:1 molar mixture of glycerine, sodium hydroxide, and a member selected from the group consisting of hardened soybean oil and hardened tallow fat, (ii) from about 0.5 grams to about 1 gram of mixed C 12 to C 18 higher tallow fatty alcohols; and (iii) from about 0.1 gram to about 2 grams of a hygroscopic surfactant selected from the group consisting of the EO 35 to EO 50 ethoxylates of mixed tallow and mixed coconut alcohols; and (b) said fabric treating composition being releasably affixed to a flexible substrate selected from the group consisting of woven, non-woven and paper sheets, at a weight ratio of fabric treating composition to substrate of from about 50:1 to about 1:50.
