Abstract
The present invention relates to lipstick compositions which comprise wax, emollient and a gelling agent wherein the inclusion of the gelling agent facilitates the retention of emollient oils particularly under high humidity and temperatures. Lipsticks of the present invention contain moisturizers which may be delivered to the lips in a non-polar/lipophilic medium in a thermodynamically stable way by using associated structures. A method of making the lipstick is also disclosed.
Claims21
A lipstick composition comprising:
- (a) a wax component comprising
- i) from about 3% to about 6% of the composition of candelilla wax;
- ii) from about 2% to about 5% of the composition of ozokerite wax;
- iii) from about 2% to about 5% of the composition of paraffin wax;
- and
- iv) from about 1% to about 4% of the composition of microcrystalline wax;
- (b) from about 1% to about 90% emollient component comprising one or more oils;
- and
- (c) a sufficient amount of an oil gelling agent to avoid sweating selected from the group consisting of hydrophobic silica, hydrophobic clays having an effective amount of an activator, propylene carbonate, ethyl cellulose, n-acyl amino acid amides and n-acyl amino acid esters and mixtures thereof,
- wherein said lipstick composition has a rheology defined by a yield value from about 1.5 to about 3.0 grams-force, and a slope m value from about 0.06 to about 0.25 grams-force per second.
A lipstick composition comprising:
- (a) a wax component comprising
- i) from about 3% to about 6% of the composition of candelilla wax;
- ii) from about 2% to about 5% of the composition of ozokerite wax;
- iii) from about 2% to about 5% of the composition of paraffin wax;
- and
- iv) from about 1% to about 4% of the composition of microcrystalline wax;
- (b) from about 1% to about 90% emollient component comprising one or more oils;
- (c) from about 0.1% to about 80% association structure consisting essentially of:
- (1) from about 3% to about 96% polar solvent;
- and
- (2) from about 4% to about 96% surfactant having a Krafft point at or below about ambient temperature;
- and
- (d) a sufficient amount of a gelling agent to avoid lipstick sweating selected from the group consisting of hydrophobic silica, hydrophobic clays having an effective amount of an activator, propylene carbonate, ethyl cellulose, n-acyl amino acid amides and mixtures thereof,
- wherein said lipstick composition has a rheology defined by a yield value from about 1.5 to about 3.0 grams-force, and a slope m value from about 0.06 to about 0.25 grams-force per second.
A lipstick composition comprising:
- (a) from about 10% to about 30% wax selected from the group consisting of candelilla, beeswax, carnauba, spermaceti, montan, ozokerite, ceresin, paraffin, bayberry, castor waxes and mixtures thereof;
- (b) from about 10% to about 80% of an emollient component comprising from about 5% to about 90%, by weight, oil;
- (c) from about 3% to about 75% of an association structure selected from the group consisting of reverse micelles, lyotropic liquid crystals and mixtures thereof and consisting essentially of:
- (1) from about 5% to about 95% of polar solvent selected from the group consisting of water, glycerine, propylene glycol, panthenol, sorbitol, butylene glycol, and mixtures thereof;
- and
- (2) from about 5% to about 95% of surfactant having a Krafft point at or below about ambient temperature and selected from the group consisting of amphoteric surfactants, anionic surfactants, cationic surfactants, nonionic surfactants and mixtures thereof;
- (d) from about 1% to about 10% ethyl cellulose;
- and
- (e) from about 1% to about 20% of a color on an anhydrous pigment weight basis.
