Abstract

Abstract Disclosed are leave-on facial emulsion compositions that are substantially free from fats and oils and anionic surfactants, which provide improved control of sebum distribution over the surface of the skin. These compositions provide improved cosmetic benefits in terms of the control of the undesirable appearance and tactile sensation of oily skin.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 113 words
A leave-on facial emulsion composition, substantially free from fats and oils and anionic surfactants, comprising: (a) from about 0.01 to about 5% of a cationic surfactant; (b) from about 0.1 to about 10% of a non-volatile organopolysiloxane having an average molecular weight of at least 200,000; (c) from about 0.01 to about 5% of one or more of a carboxylic acid copolymer; (d) from about 1% to about 10% of a humectant; and (e) a cosmetically acceptable carrier; wherein said composition provides a contact angle between sebum and skin from 0° to about 10°, and a spreading index for sebum migration greater than about 8300 pixels over the time period from 0-5 minutes.
Claim 2
Dependent Claim 113 words
A leave-on facial emulsion composition, substantially free from fats and oils and anionic surfactants, comprising: (a) from about 0.01 to about 5% of a cationic surfactant; (b) from about 0.1 to about 10% of a non-volatile organopolysiloxane having an average molecular weight of at least 200,000; (c) from about 0.01 to about 5% of one or more of a carboxylic acid copolymer; (d) from about 1% to about 10% of a humectant; and (e) a cosmetically acceptable carrier; wherein said composition provides a contact angle between sebum and skin from 0° to about 10°, and a spreading index for sebum migration greater than about 8300 pixels over the time period from 0-5 minutes.
Claim 3
Dependent Claim 32 words
An emulsion as in claim 1 wherein the cationic surfactant is an N,N,N-trialkylaminoalkylene gluconamide of the formula ##STR6## wherein R=alkyl, X=Cl-- or Br--, and n is an integer from 2 to 4.
Claim 4
Dependent Claim 16 words
An emulsion as in claim 2 wherein the cationic surfactant is y-gluconamidopropyl dimethyl 2-hydroxyethyl ammonium chloride.
Claim 5
Dependent Claim 38 words
An emulsion as in claim 3 wherein the non-volatile organopolysiloxane is selected from the group consisting of dimethicone copolyol, dimethylpolysiloxane, diethylpolysiloxane, high molecular weight dimethicone, mixed C 1 -C 3 alkyl polysiloxane, phenyl dimethicone, dimethiconol, and mixtures thereof.
Claim 6
Dependent Claim 12 words
An emulsion as in claim 4 wherein the non-volatile organopolysiloxane is dimethiconol.
Claim 7
Dependent Claim 18 words
An emulsion as in claim 5 wherein the humectant is a C 3 -C 6 diol or triol.
Claim 8
Dependent Claim 11 words
An emulsion as in claim 6 wherein the humectant is glycerin.
Claim 9
Dependent Claim 23 words
An emulsion as in claim 7 wherein the weight ratio of carboxylic acid copolymer to gluconamide is from about 1:10 to about 10:1.
Claim 10
Dependent Claim 29 words
An emulsion as in claim 8 wherein the carboxylic acid copolymer is selected from the group consisting of Carbomer 941, Carbomer 951, Carbomer 981, Carbomer 1342, and mixtures thereof.
Claim 11
Dependent Claim 21 words
An emulsion as in claim 1 wherein said emulsion further comprises from about 0.1% to about 20% of a pharmaceutical active.
Claim 12
Dependent Claim 21 words
An emulsion as in claim 1 wherein said emulsion further comprises from about 0.5% to about 20% of a sunscreening agent.
Claim 13
Dependent Claim 22 words
An emulsion as in claim 11 wherein said sunscreening agent is selected from the group consisting of ethylhexyl-p-methoxycinnamate, octocrylene, and 2-ethylhexyl N,N-dimethylaminobenzoate.
Claim 14
Dependent Claim 12 words
An emulsion as in claim 12 wherein said sunscreening agent is ethylhexyl-p-methoxycinnamate.
Claim 15
Dependent Claim 19 words
An emulsion as in claim 13 wherein said emulsion further comprises from about 0.5% to about 30% titanium dioxide.
Claim 16
Dependent Claim 29 words
A method for controlling sebum distribution on facial skin, said method comprising topically applying to the facial skin an effective amount of an emulsion composition according to claim 1.
Claim 17
Dependent Claim 29 words
A method for controlling sebum distribution on facial skin, said method comprising topically applying to the facial skin an effective amount of an emulsion composition according to claim 2.
Claim 18
Dependent Claim 29 words
A method for controlling sebum distribution on facial skin, said method comprising topically applying to the facial skin an effective amount of an emulsion composition according to claim 3.
