Description

I ——————— ¥ } alkyl acrylate/(Cy-g) alkyl acrylamide) copolymers or salts thereof, and (alkyl acrylate/diacetone acrylamide) copolymers or salts thereof.

Examples of (acrylates/(Ci-13) alkyl acrylate/(Ci-s) alkyl acrylamide) copolymers or salts thereof include (acrylates/ (Ci-13) alkyl acrylate/ (Cis) alkyl acrylamide) copolymer AMP (chemical name: 2-amino-2-methyl-l-propanol salt of alkyl esters of acrylic acid and methacrylic acid /alkyl acrylate/acrylamide copolymer; trade name:

Plascize L-9909B, from Goo Chemical Co., Ltd.; 40 wt %).

Examples of (alkyl acrylate/diacetone acrylamide) copolymers or salts thereof (alkyl acrylate/diacetone acrylamide) copolymer-AMPD (chemical name : 2-amino-2-methyl-1, 3-propanediol salt of alkyl acrylate/alkyl methacrylate/diacetone acrylamide/methacrylic acid copolymer; trade name:

Plascize L-1260, from Goo Chemical Co., Ltd.; 40 wt %), (alkyl acrylate/diacetone acrylamide) copolymer AMP (chemical name: 2-amino-2-methyl-l-propanol salt of alkyl acrylate/alkyl methacrylate/diacetone acrylamide/methacrylic acid copolymer; Plascize L-53P, from Goo Chemical Co., Ltd.; 50 wt %), and (alkyl acrylate/diacetone acrylamide) copolymer (chemical name: alkyl acrylate/alkyl methacrylate/diacetone acrylamide/methacrylic acid copolymer; trade name:

Plascize L-53, from Goo Chemical Co., Ltd.; 50 wt %).

These may be used singly or two or more may be used in combination. However, from the standpoint of the antiperspirant effect, ammonium (styrene/alkyl acrylate) copolymer, (acrylates/ (Ci-18) alkyl acrylate/ (Cig) alkyl acrylamide) copolymer AMP and octylamide acrylate/hydroxypropyl acrylate/butyl aminoethyl methacrylate copolymer are preferred. From the standpoint of the stability of the preparation, (acrylates/(Ci-1s)

EE EEE —————————————e 1 } alkyl acrylate/(Ci-s) alkyl acrylamide) copolymer AMP and octylamide acrylate/hydroxypropyl acrylate/butylaminoethyl methacrylate copolymer are especially preferred.

From the standpoint of the antiperspirant effect and the prevention of sweat stains on clothing, the content of component (B-1) is preferably from 0.1 to 2.5 wt %, and more preferably from 0.3 to 2 wt %, of the overall composition. At a component (B-1) content of less than 0.1 wt %, the antiperspirant effect, duration of the antiperspirant effect and absence of sweat stains on clothing may be inadequate. On the other hand, at a content greater than 2.5 wt %, stickiness may occur, making use less pleasant, in addition to which the stability (absence of separation and settling) of the preparation may decrease. (B-2) Vinyl Acetate-Based Anionic Polymer

Illustrative examples of vinyl acetate-based anionic polymers include (vinyl acetate/crotonic acid/vinyl neodecanoate) copolymer (trade name: RESYN 28-2930, from AkzoNobel Japan), (vinyl methyl ether/ethyl maleate) copolymer (trade name: Gantrez ES-225, from ISP Japan

KK), and (vinyl methyl ether/butyl maleate) copolymer (Gantrez ES-425, from ISP Japan KK). From the standpoint of the antiperspirant effect, the durability of this effect and the absence of sweat stains, a (vinyl acetate/crotonic acid/vinyl neodecanoate) copolymer is especially preferred. From the standpoint of the stability of the preparation, a (vinyl acetate/crotonic acid/vinyl neodecanoate) copolymer and a (vinyl methyl ether/butyl maleate) copolymer are especially preferred.

From the standpoint of the antiperspirant effect, the content of component {B-2) is preferably from 0.1 to 5 wt %, and more preferably from 1 to 4 wt %. At a component (B-2) content below 0.1 wt %, the antiperspirant effect, -g-

y x durability of the antiperspirant effect and absence of sweat stains on clothing may become inadequate. On the other hand, at more than 5 wt $%, stickiness may arise, making use less pleasant, in addition to which the stability (absence of clouding, absence of settling) of the preparation may decrease.

A commercial product (un-neutralized product or neutralized product) may be used directly without modification as the anionic polymer in this invention.

Commercial products which are un-neutralized products may ! be rendered into salts using any alkali agent, and commercial products which are neutralized products may be desalinated using any acid. No particular limitations are imposed on the alkali agent or the acid, although in the case of an alkali agent, rendering into a salt using ammonium, 2-amino-2-methyl-1l-propanol (AMP) , 2-amino-2- methyl-1, 3-propanediol (AMPD) or the like as the alkali agent is preferred; in the case of an acid, desalination using hydrochloric acid, sulfuric acid or the like is preferred. The method of desalination may entail, for example, dissolving 1 g of (acrylates/ (Ci-1g) alkyl acrylate/ (Cig) alkyl acrylamide) copolymer AMP (Plascize

L9909B, 40 wt %) in 4 g of ethanol (95 wt %). By adding to this 65 pL of hydrochloric acid and desalinating, an (acrylates/ (Ci-13) alkyl acrylate/(Ci-g) alkyl acrylamide) copolymer (35 wt %) may be obtained. In this invention, salts obtained using 2-amino-2-methyl-1l-propanol are abbreviated AMP, and salts obtained using 2-amino-2-methyl- 1, 3-propanediol are abbreviated AMPD.

In this invention, the effect of imparting durability or water resistance to the skin with component (A) differs depending on the type of component (B). Hence, from the standpoint of improving the antiperspirant effect, the duration of the antiperspirant effect and the prevention

3 1 of sweat stains on clothing, and also from the standpoint of the absence of stickiness, the optimal compounding ratios of component (A) with component (B-1) or component (B-2) are as follows.

In cases where component (B-1) is used, the ratio of component (B-1) to component (A), expressed as (B-1)/(A), is from 0.02 to 5, and preferably from 0.04 to 0.75 by weight. When this ratio is less than 0.02, both the durability of the antiperspirant effect and also the sweat stain on clothing suppressing effect worsen. On the other hand, at more than 5, the antiperspirant effect and durability thereof and the sweat stain suppressing effect worsen. Also, the stability (absence of clouding, absence of settling) of the preparation over an extended period of time worsens depending on the compounding ratio of components (A) and (B-1). From the standpoint of stability, the compounding ratio is preferably from 0.02 to 1.0, and more preferably from 0.04 to 0.5.

In cases where component (B-2) is used, the ratio of component (B-2) to component (A), expressed as (B-2)/(A4), is from 0.05 to 10, and preferably from 0.1 to 1 by weight. At less than 0.05, the durability of the antiperspirant effect and the sweat stain preventing effect worsen, whereas at more than 10, the antiperspirant effect and its durability, as well as the sweat stain on clothing preventing effect, cease to be acceptable, in addition to which the absence of stickiness decreases.

Also, the stability (absence of clouding, absence of settling) of the preparation over an extended period of time worsens depending on the compounding ratio of components (A) and (B-2). From the standpoint of stability, the compounding ratio is preferably from 0.05 to 1.0, and more preferably from 0.1 to 0.5.

EEE ————————— eee errr 3 1 [ (C) Powder]

In this invention, by further including (C) a powder, the antiperspirant effect can be made to last longer and a long-lasting deodorizing effect against body odor due to perspiration can be obtained. Illustrative examples of the powder include magnesia-silica, silica, talc, nylon resin and silicone resin. A single powder may be used alone, or two or more powders may be used in combination.

No particular limitation is imposed on embodiments of the deodorant composition of the invention. Application as, for example, a cosmetic material, a drug or a quasi- drug is possible. Use as a personal deodorant composition such as for the underarm area is also possible. The form of the inventive deodorant composition is exemplified by various types, such as that of a solid, semi-solid, gel, liquid or cream, preparation being possible based on the customary methods for these forms. In addition, in the practice of this invention, preparation 1s possible by formulating the respective ingredients in a continuous solvent phase (single layer). Specifically, rendering the deodorant composition of the invention into, for example,

=e =e eee ee meee rrr

J ¥ a roll-on product, gel, lotion, mist, stick, cream, sheet or deodorant foundation is preferred. From the standpoint of the durability of the antiperspirant effect and the durability of the deodorizing effect, a roll-on product, gel, lotion or mist is more preferred.

In particular, applying the composition of the invention to the skin in a water-dissolved state is effective for exhibiting the effects thereof. As liquid- type forms such as roll-on products, gels, lotions and mists, preferred use can be made of roll-on type, gel type and lotion type preparations because they can be closely applied and are able to exhibit highly advantageous effects. The deodorant composition of the invention is preferably rendered into a deodorant composition for filling into a roll-on container, a deodorant product obtained by filling the deodorant composition into a roll- on container, or a liquid antiperspirant deodorant product composed of a deodorant composition and a roll-on container having an applicator ball filled with this composition. A roll-on type preparation is housed in a commonly known roll-on container; the deodorant composition can be applied by transferring the composition to the ball which is rotatably held in a partially exposed state on the container by a holder, and bringing the ball into contact with the skin at the time of use. It is also preferable to render the deodorant composition into the form of a gel which is filled into a bottle-type container and applied directly using the container, or into the form of a gel or lotion which is applied using the fingertips or hand.

The method of preparing the deodorant composition of the invention is not particularly limited and may be suitably selected according to the intended purpose. The deodorant composition can be obtained by mixing components

3 J (A) and (B), and also, where necessary, component (C) and optional ingredients, together with ethanol and water (which are included as the balance of the composition so that the overall amount of deodorant composition becomes 100 wt %).

DESCRIPTION OF EMBODIMENTS

[{(A) Antiperspirant Component]

The antiperspirant component is not subject to any particular limitation, provided it is a component that imparts an antiperspirant effect. Illustrative examples include aluminum chloride, aluminum sulfate, aluminum potassium sulfate, aluminum acetate, chlorohydroxyaluminum, allantoin chlorohydroxyaluminum, chlorohydroxyaluminum-propylene glycol complexes and chlorohydroxyaluminum/zirconium-glycine complexes. These may be used singly or two or more may be used in combination. Of these, from the standpoint of the antiperspirant effects, chlorohydroxyaluminum, a chlorohydroxyaluminum-propylene glycol complex or a chlorohydroxyaluminum/zirconium-glycine complex is preferred. Chlorohydroxyaluminum is especially preferred.

EE ———————— eee ere. 1 3

The content of component (A), from the standpoint of the antiperspirant effect, is preferably from 0.1 to 15 wt %, and more preferably from 1.5 to 10 wt %, of the overall composition. At less than 0.1 wt %, the antiperspirant effect and its durability, and also the sweat stain suppressing effect, may be inadequate. On the other hand, a content of more than 15 wt % may lead to a decline in the absence of stickiness, a worsening of skin irritation or inferior stability (absence of clouding, absence of settling) of the preparation. [(B) Anionic Polymer]

An anionic polymer is formulated in order to, through interaction with the antiperspirant component (7), increase the antiperspirant effect and prevent sweat stains on clothing. As this anionic polymer, preferred use can be made of (B-1) an acrylic acid-based polymer or (B-2) a vinyl acetate-based polymer. (B-1) Acrylic Acid-Based Anionic Polymer

The acrylic acid-based anionic polymer is exemplified by an ammonium (styrene/alkyl acrylate) copolymer (trade name: Yodosol GH41lF, available from AkzoNobel Japan, 45 wt %), an ammonium alkyl acrylate copolymer (trade name:

Yodosol GH800F, available from AkzoNobel Japan, 45 wt %), an (octylamide acrylate/hydroxypropyl acrylate/butylaminoethyl methacrylate) copolymer (trade name: AMPHOMER 28-4910, available from AkzoNobel Japan), an (alkyl acrylate/diacetone acrylamide) copolymer- amodimethicone (chemical name: mixture of alkyl acrylate- alkyl methacrylate-diacetone acrylamide-methacrylic acid copolymer and aminoethylaminopropylmethylsiloxane- dimethylsiloxane copolymer; trade name: SETSIL314, from
