Abstract

Abstract A toilet bar is provided containing either soap or a synthetic detergent as a cleansing agent and wherein an alkali metal salt of an acyl lactylate or glycolate is incorporated in the bar as a skin conditioning member which imparts a non-oily, talc-like, silky, very smooth, non-powdery feel to the user's skin. The preferred skin conditioning member is from about 1% to about 5% by weight of sodium isostearoyl lactylate incorporated in the bar.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 160 words
A toilet bar having enhanced skin conditioning properties by imparting to the user's skin a non-oily, talc-like, silky, very smooth, non-powdery feel and comprising a solid compressed form containing, on a percent by weight basis: (a) from about 40% to about 90% of a cleansing agent which is physiologically acceptable to the skin and selected from the group consisting of (1) solid anionic and aliphatic nonionic synthetic detergents which are moldable into a solid bar and exhibit surface active characteristics and have required lathering properties, (2) soaps selected from the group consisting of alkali metal, ammonium and alkanolamine salts of fatty acids containing from 8 to 24 carbon atoms, and (3) combinations thereof; (b) from about 1% to about 5% of at least one skin conditioning member compatible with said cleansing agent and selected from the group consisting of alkali metal isostearyl lactylate or glycolate and their physiologically acceptable amine salts; and (c) from about 4% to about 25% water.
Claim 2
Dependent Claim 160 words
A toilet bar having enhanced skin conditioning properties by imparting to the user's skin a non-oily, talc-like, silky, very smooth, non-powdery feel and comprising a solid compressed form containing, on a percent by weight basis: (a) from about 40% to about 90% of a cleansing agent which is physiologically acceptable to the skin and selected from the group consisting of (1) solid anionic and aliphatic nonionic synthetic detergents which are moldable into a solid bar and exhibit surface active characteristics and have required lathering properties, (2) soaps selected from the group consisting of alkali metal, ammonium and alkanolamine salts of fatty acids containing from 8 to 24 carbon atoms, and (3) combinations thereof; (b) from about 1% to about 5% of at least one skin conditioning member compatible with said cleansing agent and selected from the group consisting of alkali metal isostearyl lactylate or glycolate and their physiologically acceptable amine salts; and (c) from about 4% to about 25% water.
Claim 3
Dependent Claim 22 words
A toilet bar as set forth in claim 1 wherein said synthetic detergent is a coconut oil acid ester of sodium isethionate.
Claim 4
Dependent Claim 34 words
A toilet bar as set forth in claim 1 wherein said soap is the salt of a fatty acid component of from about 80% to 85% tallow and about 20% to 15% coconut oil.
Claim 5
Dependent Claim 18 words
A toilet bar as set forth in claim 1 wherein said member is sodium isostearoyl lactylate or glycolate.
Claim 6
Dependent Claim 20 words
A toilet bar as set forth in claim 1 wherein said member is present in an amount of about 3%.
Claim 7
Independent Claim 180 words
A method of imparting a non-oily, talc-like, silky, very smooth, non-powdery feel to a user's skin following cleansing with a toilet bar, said method comprising: (I) applying to the skin an effective amount of a cleansing composition from a solid compressed toilet bar, said bar containing on a percent by weight basis: (a) from about 40% to about 90% of a cleansing agent which is physiologically acceptable to the skin and selected from the group consisting of (1) solid anionic and aliphatic nonionic synthetic detergents which are moldable into a solid bar and exhibit surface active characteristics and have required lathering properties, (2) soaps selected from the group consisting of alkali metal, ammonium and alkanolamine salts of fatty acids containing from 8 to 24 carbon atoms, and (3) combinations thereof; (b) from about 1% to about 5% of at least one skin conditioning agent and selected from the group consisting of alkali metal isostearyl lactylate or glycolate and their physiologically acceptable amine salts; and (c) from about 4% to about 25% water; and (II) subsequently rinsing the skin with water.
Claim 8
Independent Claim 180 words
A method of imparting a non-oily, talc-like, silky, very smooth, non-powdery feel to a user's skin following cleansing with a toilet bar, said method comprising: (I) applying to the skin an effective amount of a cleansing composition from a solid compressed toilet bar, said bar containing on a percent by weight basis: (a) from about 40% to about 90% of a cleansing agent which is physiologically acceptable to the skin and selected from the group consisting of (1) solid anionic and aliphatic nonionic synthetic detergents which are moldable into a solid bar and exhibit surface active characteristics and have required lathering properties, (2) soaps selected from the group consisting of alkali metal, ammonium and alkanolamine salts of fatty acids containing from 8 to 24 carbon atoms, and (3) combinations thereof; (b) from about 1% to about 5% of at least one skin conditioning agent and selected from the group consisting of alkali metal isostearyl lactylate or glycolate and their physiologically acceptable amine salts; and (c) from about 4% to about 25% water; and (II) subsequently rinsing the skin with water.
