Abstract

The present disclosure relates to anhydrous cosmetic compositions which contain a combination of a strongly swelling and a low-swelling water-absorbing component, an odor-absorbing component and a deodorant active ingredient. These compositions have an outstanding deodorizing effect and improved sensory features and additionally result in a minimization of sweat spots on textiles. Furthermore, the present disclosure relates to a cosmetic product containing these anhydrous compositions and the use of this composition or product for reduction of the body odor released by perspiration. Finally, the present disclosure relates to the use a strongly swelling water-absorbing component in combination with an odor-absorbing component to improve the sensory characteristics of anhydrous deodorant compositions.

First claim

The invention claimed is:

1. An anhydrous cosmetic composition consisting of:
a) a strongly swelling water-absorbing component (A) consisting of sodium carboxymethyl cellulose alone or in combination with crosslinked copolymers of acrylamide and acrylic acid, and optionally including one or more additional compounds from the group of xanthan gum, gellan gum, cellulose gum, linear or crosslinked sodium polyacrylates, alginic acid and its salts, carrageenan and its salts, agar agar, pectins, guar gum, starch ethers, starch esters, locust bean flour, gelatins, succinoglycan, polyvinylpyrrolidone, crosslinked copolymers of acrylamide and acrylic acid, tara gum and mixtures thereof;
b) a low-swelling water-absorbing component (B) consisting of hydrophilic silica or cellulose or a combination thereof;
c) an odor-absorbing component (C) comprising cyclodextrin;
d) a deodorant active ingredient (D) consisting of phenoxyethanol, caprylyl glycol, 1,2-hexanediol, α-(2-ethylhexyl) glycerol, benzyl heptanol and/or butyloctanoic acid, or a mixture thereof;
e) an anhydrous cosmetic carrier (E); and
optionally one or more additional ingredients selected from the group of: (i) fragrances; (ii) waxes; (iii) emulsifiers and/or surfactants; (iv), chelating agents; (v) polyethylene glycols; (vi) skin-cooling active ingredients; (vii) pH control agents; (viii) skin-care active ingredients, selected from the group consisting of: moisturizers, skin-calming substances, skin-lightening substances, and skin-smoothing substances; (ix) preservatives; and (x) mixtures thereof,
wherein the sodium carboxymethyl cellulose of component (A) consists of a particle form, wherein at least 30 wt. % of the particle form has an average particle size D 50 of more than 10 micrometers (μm) and wherein 100 wt. % of the particle form has an average particle size D 50 of less than 200 μm, and
wherein the anhydrous cosmetic composition consists of a mixture of components (A), (B), (C), ingredient (D), cosmetic carrier (E), and optionally the one or more additional ingredients.

2. The anhydrous cosmetic composition according to claim 1 wherein the strongly swelling water-absorbing component (A) is included in a total quantity of from about 1.0 to about 40 wt. %, relative to a total weight of the anhydrous cosmetic composition.

3. The anhydrous cosmetic composition according to claim 1 , wherein the low-swelling water-absorbing component (B) is included in a total quantity of from about 1.0 to about 40 wt. %, relative to a total weight of the anhydrous cosmetic composition.

4. The anhydrous cosmetic composition according to claim 1 , wherein the anhydrous cosmetic composition has a weight ratio of the strongly swelling water-absorbing component (A) to the low-swelling water-absorbing component (B) of from about 8:2 to about 2:8.

5. A cosmetic product, consisting of:
a) an anhydrous cosmetic composition consisting of:
a strongly swelling water-absorbing component (A) consisting of sodium carboxymethyl cellulose alone or in combination with crosslinked copolymers of acrylamide and acrylic acid, and optionally including one or more additional compounds from the group of xanthan gum, gellan gum, cellulose gum, linear or crosslinked sodium polyacrylates, alginic acid and its salts, carrageenan and its salts, agar agar, pectins, guar gum, starch ethers, starch esters, locust bean flour, gelatins, succinoglycan, polyvinylpyrrolidone, crosslinked copolymers of acrylamide and acrylic acid, tara gum and mixtures thereof;
a low-swelling water-absorbing component (B) consisting of hydrophilic silica or cellulose or a combination thereof;
an odor-absorbing component (C) comprising cyclodextrin;
a deodorant active ingredient (D) consisting of phenoxyethanol, caprylyl glycol, 1,2-hexanediol, α-(2-ethylhexyl) glycerol, benzyl heptanol and/or butyloctanoic acid, or a mixture thereof;
an anhydrous cosmetic carrier (E); and
optionally one or more additional ingredients selected from the group of: (i) fragrances; (ii) waxes; (iii) emulsifiers and/or surfactants; (iv), chelating agents; (v) polyethylene glycols; (vi) skin-cooling active ingredients; (vii) pH control agents; (viii) skin-care active ingredients, selected from the group consisting of: moisturizers, skin-calming substances, skin-lightening substances, and skin-smoothing substances; (ix) preservatives; and (x) mixtures thereof,

wherein the sodium carboxymethyl cellulose of component (A) consists of a particle form, wherein at least 30 wt. % of the particle form has an average particle size D 50 of more than 10 micrometers (μm) and wherein 100 wt. % of the particle form has an average particle size D 50 of less than 200 μm, and
wherein the anhydrous cosmetic composition consists of a mixture of components (A), (B), (C), ingredient (D), cosmetic carrier (E), and optionally the one or more additional ingredients; and
b) a propellant (F).

6. The anhydrous cosmetic composition of claim 1 wherein:
the strongly swelling water-absorbing component (A) is included in a total quantity of from about 1.5 to about 30 wt. %, relative to a total weight of the anhydrous cosmetic composition.

7. The anhydrous cosmetic composition of claim 1 wherein:
the strongly swelling water-absorbing component (A) is included in a total quantity of from about 2.0 to about 20 wt. %, relative to a total weight of the anhydrous cosmetic composition.

8. The anhydrous cosmetic composition of claim 1 wherein:
the strongly swelling water-absorbing component (A) is included in a total quantity of from about 3.0 to about 15 wt. %, relative to a total weight of the anhydrous cosmetic composition.

9. The anhydrous cosmetic composition of claim 1 wherein:
the low-swelling water-absorbing component (B) is included in a total quantity of from about 1.5 to about 30 wt. %, relative to a total weight of the anhydrous cosmetic composition.
