Abstract
The present invention relates to a shear-thinning or pseudoplastic cosmetic composition. Zeta potentials may be balanced such that a first ratio of the first zeta potential to the second zeta potential may be approximately 1:2. A second ratio of the first zeta potential to the third zeta potential may be approximately 1:2. And, a third ratio of the second zeta potential to the third zeta potential may be approximately 1:1. Balancing zeta potentials may ensure the shear-thinning cosmetic composition can dispense in its original viscous form and as a fine mist through a single device.
Claims10
A shear-thinning cosmetic composition, comprising:
- a first active ingredient having a first zeta potential, wherein the first active ingredient is 90% aqueous mixture of carrageenan;
- a second active ingredient having a second zeta potential, wherein the second active ingredient is lithium magnesium sodium silicate;
- and
- a third active ingredient having a third zeta potential, wherein the third active ingredient is polyquaternium-6;
- wherein a first ratio of the first zeta potential to the second zeta potential is approximately 1:2,
- wherein a second ratio of the first zeta potential to the third zeta potential is approximately 1:2,
- wherein a third ratio of the second zeta potential to the third zeta potential is approximately 1:1,
- wherein the shear-thinning cosmetic composition provides a viscosity in the range of approximately 100,000 centistokes (cSt) to approximately 500,000 cSt at a low shear of approximately 1 to 10 N/m2 at room temperature of approximately 20 to 25 degrees Celsius;
- and
- wherein the shear-thinning cosmetic composition exhibits a mist form at a high shear of approximately 80 to 120 N/m2.
