Abstract

A personal care composition comprising a cosmetically acceptable base and inorganic particulate material, for example, a shower gel or hair shampoo, and a method of making the personal care composition. A cleaning composition comprising a base and inorganic particulate material, for example, a hard surface cleansing composition, and a method of making the cleaning composition. A composition, for example, a personal care composition, use of an inorganic particulate material having a d50 of from about 0.1 μm to about 200 μm in such a composition, and a method for making such a composition.

First claim

The invention claimed is:

1. A personal care cleansing composition comprising:
a cosmetically acceptable base selected from the group consisting of a liquid, a gel, an emulsion, a lotion or a paste; and
an expanded inorganic particulate material having a density ranging from about 0.10 g/cc to about 2.0 g/cc, wherein the expanded inorganic particulate material comprises expanded spherical perlite, and at least 50 wt. % of the spherical perlite is in the form of microspheres that are substantially closed and hollow.

2. The personal care cleansing composition according to claim 1 , wherein the expanded inorganic particulate material has a density ranging from about 0.10 g/cc to about 1.0 g/cc.

3. The personal care cleansing composition according claim 1 , wherein the expanded inorganic particulate material has a density of from about 0.20 to about 0.50 g/cc.

4. The personal care cleansing composition according to claim 1 , wherein the inorganic particulate has a d90 of no greater than about 500 μm.

5. The personal care cleansing composition according to claim 1 , wherein the inorganic particulate material has a d10 of at least about 30 μm and a d90 of no greater than about 500 μm.

6. The personal care cleansing composition according to claim 1 , wherein the inorganic particulate comprises microspheres of expanded spherical perlite and having a d10 of at least about 50 μm and a d90 of no greater than about 450 μm, and having a density of from about 0.20 to about 0.50 g/cc.

7. The personal care cleansing composition according to claim 1 , wherein the inorganic particulate material has a d10 of at least about 10 μm and a d90 of no greater than about 450 μm.

8. The personal care cleansing composition according to claim 1 , wherein the inorganic particulate is present in an amount of from about 0.1 wt. % to about 20 wt. %, based on the total weight of the personal care cleansing composition.

9. The personal care cleansing composition according to claim 1 , wherein the inorganic particulate is present in an amount of from about 0.5 wt. % to about 5 wt. %.

10. The personal care cleansing composition according to claim 1 , further comprising one or more of: surfactant(s), thickening agent(s), suspending agent(s), skin conditioning/moisturising agent(s), hair conditioning/moisturising agent(s), perfume(s), fragrance(s), opacifier(s), pearlescing agent(s), colouring(s), preservative(s), chelating agent(s), humectants(s), herb and/or plant extract(s), essential oil(s), protein(s), pH adjusting agent(s), and anti-microbial(s).

11. The personal care cleansing composition according to claim 1 , wherein the personal care cleansing composition is a skin cleansing composition.

12. The personal care cleansing composition according to claim 11 , wherein the skin cleansing composition is a soap.

13. The personal care cleansing composition according to claim 12 , wherein the soap is a liquid soap.

14. The personal care cleansing composition according to claim 13 , wherein the soap is selected from a hand soap, a face soap, a bodywash, a shower gel, a bath gel, a shaving foam, and a shaving gel.

15. The personal care cleansing composition according claim 1 , wherein the personal care composition is a hair shampoo.

16. The personal care cleansing composition according claim 1 , wherein the inorganic particulate material aids or provides exfoliation of the skin.
