主权项

1. A method of making a shampoo composition having a high perfume efficiency comprising:
adding about 10 weight % (wt. %) to about 25 wt. %, based on the total weight of the shampoo composition, of anionic surfactants; and adding about 0.02 wt. % to about 0.3 wt. %, based on the total weight of the shampoo composition, of a perfume accord comprising at least 10 perfume raw materials, determining that the odor intensity score of the shampoo composition has an odor intensity score (OIS) of from about 0.2 to about 1.0, as determined by Formula I:1/n⁢∑i=1n⁢⁢Ci/Mi=OISFormula⁢⁢(I) wherein n is the number of perfume raw materials present in the perfume accord, Ci is the concentration of the ith perfume raw material in the shampoo composition, and Mi is the concentration of the ith perfume raw material sufficient to provide an odor intensity rating (OIR) in a shampoo composition chassis of about 2 on a scale from zero to five, wherein the shampoo composition chassis is the shampoo composition without the perfume accord.
