Benefits of technology

[0004]In accordance with some of the preferred embodiments, there has now been provided a personal care product comprising a composition that is applied to the body or clothing, or an article applied against the body; and a plurality of particles associated with the composition or a component of the article, the plurality of particles, at least some of the plurality of particles comprising a cyclodextrin complexing material and a fragrance material, wherein the percent of the fragrance material that is complexed with the cyclodextrin is greater than about 90%, so that the perceptibility of the fragrance is minimized prior to its release, and wherein the composition does not contain an antiperspirant active.
[0008]The preferred embodiments described above explicitly exclude an antiperspirant active. However, other preferred embodiments can include such an active. In accordance with one of these preferred embodiments, there has now been provided a personal care product, comprising an aqueous carrier material; and a plurality of particles disposed in the aqueous carrier material, the plurality of particles comprising a cyclodextrin complexing material and a fragrance material, wherein the percent of the fragrance material that is complexed with the cyclodextrin is greater than about 90%, so that the perceptibility of the fragrance is minimized prior to its release, and wherein the plurality of particles are coated with a hydrophobic coating material to minimize premature release due to the presence of the aqueous carrier material.
[0009]In accordance with another of these preferred embodiments, there has now been provided a personal care product, comprising an aqueous carrier material; and a plurality of particles disposed in the aqueous carrier material, the plurality of particles comprising a cyclodextrin complexing material and a fragrance material, wherein the plurality of particles are formed using a process comprising a step of spray drying, and wherein the plurality of particles are coated with a hydrophobic coating material to minimize premature release due to the presence of the aqueous carrier material.

Problems solved by technology

Since the personal care products of the present invention include compositions that are applied to the body and articles that are worn / applied against the body, a grainy or gritty feel is likely undesirable for a significant number of users.

[0062]Example 1 can be made as follows: Petrolatum coated cyclodextrin fragrance complexes are prepared by combining spray dried complex particles with petrolatum (e.g., super white protopet manufactured by Witco) at a ratio of 1:1 in a Hamilton Beach custom grind coffee grinder (model 80365). Turn the grinder to the highest speed and mix until the petrolatum fully coats the spray dried cyclodextrin fragrance complex particles. The mixture may have a paste-like consistency. In a suitable vessel, combine all solvents (propylene glycol, dipropylene glycol, water), gellants (sodium stearate, Witconol APM) and tetrasodium EDTA and then heat to 80° C. while mixing. Then add the petrolatum coated complex paste and mix. Cool the mixture to 70° C.,...

Abstract

Personal care products are provided. An exemplary personal care product includes a composition that is applied to the body or clothing, or an article applied against the body; a plurality of particles associated with the composition or a component of the article, the plurality of particles, at least some of the plurality of particles comprising a cyclodextrin complexing material and a first fragrance material, wherein the percent of the first fragrance material that is complexed with the cyclodextrin is greater than about 90%, so that the perceptibility of the first fragrance is minimized prior to its release; and a second fragrance material that is not complexed with the cyclodextrin and that is different from the first fragrance material, wherein the composition or article does not contain an antiperspirant active.

Description
