Cosmetic composition containing microcrystalline cellulose
View Patent ↗A sprayable cosmetic composition is disclosed. In one aspect, the composition comprises a sunscreen agent or mixture of sunscreen agents; an emulsifier or mixture of emulsifiers; optionally an emollient or mixture of emollients; a rheology control agent; and water. The rheology control agent is microcrystalline cellulose. When sprayed on the skin or hair, the cosmetic compositions of the invention produce a fine mist that deposits evenly with no dripping and no aggregate or blobs.
1. A sprayable composition, the sprayable composition comprising:
a cosmetic agent or mixture of cosmetic agents selected from the group consisting of sunscreen agents, self-tanning agents, depilatories, exfoliating agents, and mixtures thereof;
an emulsifier or mixture of emulsifiers;
a rheology control agent; and
55-80 wt % water based on the total weight of the sprayable composition;
in which:
the cosmetic agent or mixture of cosmetic agents comprises about 0.1 wt % to 40 wt % of the composition;
the emulsifier or mixture of emulsifiers comprises about 0.2 wt % to about 20 wt % of the composition;
the rheology control agent comprises about 0.2 wt % to about 3 wt % of the composition;
the rheology control agent comprises coprocessed microcrystalline cellulose and carboxymethylcellulose, wherein said coprocessed microcrystalline cellulose has an average particle size of 50 microns or less;
the composition has a viscosity at high shear of 120 Pa-s or less; and
wherein said composition is sprayable in a non-aerosol spray device.
2. The composition of claim 1 in which the composition has a viscosity at high shear of 100 Pa-s or less.
3. The composition of claim 1 or claim 2 in which the cosmetic agent or mixture of cosmetic agents comprises about 2 wt % to about 20 wt % of cosmetic agents selected from the group consisting of emollients, occlusive agents, moisturizers, and humectants.
4. The composition as in any one of claims 1 - 2 in which the coprocessed microcrystalline cellulose has an average particle size of below 10 microns.
5. The composition as in any one of claims 1 - 2 in which the microcrystalline cellulose is a water-dispersible microcrystalline cellulose.
6. The composition of claim 1 in which the coprocessed microcrystalline cellulose comprises the microcrystalline cellulose and sodium salt of carboxymethylcellulose in a ratio of about 85/15, by weight.
7. The composition as in any one of claim 1 - 2 or 6 in which the coprocessed microcrystalline cellulose has an average particle size of below 1 micron.
8. The composition as in any one of claim 1 - 2 or 6 in which the cosmetic agent comprises a sunscreen agent or a mixture of sunscreen agents.
9. The composition of claim 8 in which the sunscreen agent or mixture of sunscreen agents comprises an inorganic sunscreen agent or a mixture of inorganic sunscreen agents.
10. The composition as in any one of claim 1 - 2 or 6 in which the sunscreen agent or mixture of sunscreen agents comprises an organic sunscreen agent or a mixture of organic sunscreen agents.
11. The composition of claim 8 in which the composition has a sun protection factor of at least 12.
12. The composition of any one of claim 1 to 2 or 6 in which the composition comprises a self-tanning agent.
13. The composition as in any one of claim 1 - 2 or 6 in which the composition has a viscosity at a high shear of 80 Pa-s or less.
14. The composition as in any one of claim 1 - 2 or 6 in which the composition has a rundown time of 100 seconds or greater.
15. A method for applying a cosmetic composition, the method comprising the step of spraying the cosmetic composition in any one of claim 1 - 2 or 6 onto the skin, onto the hair, or onto the skin and the hair.
