Visually patterned and oriented compositions
Structured personal care compositions comprising a particle having an aspect ratio of greater than 1.5 are contemplated, as well as methods for using such compositions. The compositions provide a visually distinguishable, oriented pattern that is aesthetically pleasant to provide consumer appeal and product identification.

b) at least a second visually distinguishable zone in physical contact with the at least first visually distinguishable zone,
wherein the at least first visually distinguishable zone and the at least second visually distinguishable zone form a visibly distinguishable pattern, wherein the composition includes a crosslinked polycarboxylate thickener as a structural material, present in the at least first visually distinguishable zone, that retains the orientation of the visible particles in the composition, wherein the composition is packaged in a container using laminar flow; substantially means that the visible particles plane and the plane of flow do not intersect within the container,
and wherein the visually patterned oriented composition is a liquid, a gel or a foam.
2. The composition of claim 1 , wherein at least 50% of the visible particles have their x-y planes substantially parallel, parallel, or coincident to x-y planes of the other visible particles, and substantially means that the x-y planes of the visible particles do not intersect within the container.
3. The composition of claim 1 , wherein the visible particle comprises at least one particle chosen from films, metallic particles, naturally reflective particles, interference pigments, multi-layered pigments, solid and liquid crystals, visible beads, deformable visible beads, mica, metallic films, silicates, borosilicates, glass, and mixtures or combinations thereof.
4. The composition of claim 3 , wherein the visible particle is selected from visible beads, deformable visible beads, mica, and/or metallic films.
5. The composition of claim 4 , wherein the visible particle is mica.
6. The composition of claim 5 , further comprising a visible bead.
7. The composition of claim 1 , wherein the visible particle has an aspect ratio of 2:1 or greater.
8. The composition of claim 1 , wherein the visible particle has an aspect ratio greater than 15:1.
9. The composition of claim 1 , wherein at least the first visually distinguishable zone has a yield point of 3 to 100 Pa at room temperature.
10. The composition of claim 1 , wherein at least the first visually distinguishable zone has a viscosity of at least 10,000 mPas at room temperature.
11. A method of making the visually patterned oriented composition of claim 1 comprising:
a) preparing at least a first composition comprised of a first vehicle and visible particles having an aspect ratio greater than 1.5:1 and a particle size of 50 μm to 5000 μm in a longest dimension;
b) preparing at least a second composition comprised of at least a second vehicle; and
c) dispensing the at least first composition and the at least second composition into a container using laminar flow in a manner that provides the at least first visually distinguishable zone comprised of the at least first composition in which the visible particles are oriented in a plane substantially parallel to the plane of flow of the first composition, and the at least second visually distinguishable zone comprised of the at least second composition, the at least second visually distinguishable zone in contact with the at least first visually distinguishable zone, wherein the at least first visually distinguishable zone and the at least second visually distinguishable zone form a visibly distinguishable pattern, and wherein the composition includes a crosslinked polycarboxylate thickener as a structural material, present in the at least first visually distinguishable zone, that retains the orientation of the visible particles in the composition, and substantially means that the visible particles plane and the plane of flow do not intersect within the container, and wherein the visually patterned oriented composition is a liquid, a gel or a foam.
12. The method of claim 11 , wherein the visible particle comprises at least one particle chosen from films, metallic particles, naturally reflective particles, interference pigments, multi-layered pigments, solid and liquid crystals, visible beads, deformable visible beads, mica, metallic films, silicates, borosilicates, glass, and mixtures or combinations thereof.
