Abstract

The present invention provides personal care compositions having efficient perfume blooms or bursts. The personal care compositions include shampoo and body wash compositions, and comprise perfume materials having high perceived odor intensity at low concentrations of perfume materials.

First claim

The invention claimed is:

1. A method of making a body wash composition comprising:
adding about 3 wt. % to about 15 wt. %, based on the total weight of the body wash composition, of anionic surfactants; and
adding about 0.05 wt. % to about 0.4 wt. %, based on the total weight of the body wash composition, of a perfume accord comprising at least 10 perfume raw materials, and
determining that the body wash composition has an odor intensity score (OIS) of at least about 0.8, as determined by Formula I:

wherein n is the number of perfume raw materials present in the perfume accord, C i is the concentration of the i th perfume raw material in the body wash composition, and M i is the concentration of the i th perfume raw material sufficient to provide an odor intensity rating (OIR) in a body wash composition chassis of about 2 on a scale from zero to five,
wherein the body wash composition chassis is the body wash composition without the perfume accord.

2. The method of making a body wash composition of claim 1 , wherein the OIS is about 0.8 to about 2.

3. A method of making a body wash composition comprising:
adding about 3 weight % (wt. %) to about 15 wt. %, based on the total weight of the body wash composition, of anionic surfactants; and
adding about 0.4 wt. % to about 1.5 wt. %, based on the total weight of the body wash composition, of a perfume accord comprising at least 10 perfume raw materials,
determining that the body wash composition has an odor intensity score (OIS) of at least about 1, as determined by Formula I:

wherein n is the number of perfume raw materials present in the perfume accord, C i is the concentration of the i th perfume raw material in the body wash composition, and M i is the concentration of the i th perfume raw material sufficient to provide an odor intensity rating (OIR) in a body wash composition chassis of about 2 on a scale from zero to five,
wherein the body wash composition chassis is the body wash composition without the perfume accord.

4. The method of making a body wash composition of claim 3 , wherein the OIS is about 1 to about 11.

5. The method of claim 3 , wherein M i is about 1 ppm to about 1000 ppm for about 20% to about 100% of the perfume raw materials present in the perfume accord.

6. The method of claim 5 , wherein M i is about 1 ppm to about 800 ppm.

7. The method of claim 6 , wherein M i is about 1 ppm to about 600 ppm.

8. The method of claim 3 , wherein C i /M i is at least 0.05 for about 75% to about 100% of the perfume raw materials present in the perfume accord.

9. The method of claim 3 , wherein C i /M i is at least 0.1 for about 70% to about 100% of the perfume raw materials present in the perfume accord.

10. The method of claim 3 , wherein C i /M i is at least 0.2 for about 45% to about 100% of the perfume raw materials present in the perfume accord.

11. The method of claim 3 , wherein C i /M i is at least 0.3 for about 40% to about 100% of the perfume raw materials present in the perfume accord.

12. The method of claim 3 , wherein C i /M i is at least 0.4 for about 35% to about 100% of the perfume raw materials present in the perfume accord.

13. The method of claim 3 , wherein C i /M i is at least 0.5 for about 30% to about 100% of the perfume raw materials present in the perfume accord.

14. The method of claim 3 , wherein C i /M i is at least 0.6 for about 25% to about 100% of the perfume raw materials present in the perfume accord.

15. The method of claim 3 , wherein C i /M i is at least 0.7 for about 20% to about 100% of the perfume raw materials present in the perfume accord.

16. The method of claim 15 , wherein C i /M i is at least 0.8.

17. The method of claim 15 , wherein C i /M i is at least 0.9.

18. The method of claim 3 , wherein C i /M i is at least 1 for about 15% to about 100% of the perfume raw materials in the perfume accord.
