Description

TOPICAL PRODUCT WITH VISUAL INDICATOR TECHNICAL FIELD

This invention relates to products, for example, antiperspirants and deodorants, that are topically applied to the skin. BACKGROUND

Antiperspirant and deodorant compositions are well known personal care products. The compositions come in a variety of forms and may be formulated, for example, into aerosols, pumps, sprays, liquids, roll-on, lotion, creams, and sticks (both hard and soft), etc. There are various types of stick antiperspirant compositions. In one type, an antiperspirant salt is suspended in an anhydrous vehicle often including a solid water-insoluble wax. In a second type, an antiperspirant salt is dissolved in a liquid vehicle such as propylene glycol and gelled with a gelling agent such as dibenzylidene sorbitol. A third type includes an emulsion of an aqueous phase containing the antiperspirant salt and an oil phase containing, for example, a volatile silicone, fragrances, gellants, and other additives.

Stick antiperspirant products include an antiperspirant composition within a container. During use of the product, the top of the container is removed and the application surface of the composition is contacted with the underarm. Some of the composition is transferred to the sldn, and the container generally also includes some mechanism for moving the composition upwards through the container to continue to provide an exposed application surface. Sometimes, when the composition has largely been consumed, the small portion of remaining stick in the composition can fall out of the container, for example, onto the floor. If the product does not fall onto the floor, the first indication that a consumer may get that the product largely has been consumed is the contact of the plastic platform used to move the composition upward through the container with the skin.

SUMMARY Generally, the invention relates to a product for application to the skin. The product includes a container having an upper end and a non-flowable composition within the container. The composition has an application surface at the open end of the container. The application surface continuously wears away during application of the composition to the skin. The composition includes a cosmetic ingredient such as an antiperspirant salt, deodorant active ingredient, sunscreen, vitamin E, aloe, alphahydroxy acid, fragrance and/or a therapeutic ingredient such as a pharmaceutically active compound (e.g., anti-inflammatory agent, hair growth promoter or inhibitor, vitamin E, a alphahydroxy acid, etc.). "Non-flowable", as used herein, means the composition does not flow out of the container when the container is inverted at room temperature.

In one aspect, the application surface has a first visual appearance prior to first use and a second visual appearance at some time after the first use caused by a change in the composition. The change can be, for example, a different color resulting from using a colorant (e.g., dye, pigment, colored bead or colored capsule) in the composition. The colorant may be used to provide a pattern (e.g., a stripe, swirl, marbling, or central core) on the application surface that either changes or becomes visible after first use of the product. The colorant may also be used to cause a change in the color of the entire application surface to provide the second visual appearance. The second visual appearance may also result from, for example, a structural change (e.g., a gap) in the composition. For purposes of the present invention, the visible appearance of a platform supporting the lower end of the composition is not considered a change in the composition and does not constitute a second visual appearance of the application surface hereunder.

In some preferred embodiments, the second visual appearance occurs when the end is near, i.e., when the composition has diminished in height by at least 70% and, preferably, at least 80%. As a result, the user will know when to have a replacement product available and can discard the product before, for example, the remaining composition in the container is dislodged from the container.

In some preferred embodiments, the composition includes a stripe extending across the application surface prior to first use. The stripe has a different color or opacity than the adjacent application surface. The stripe or the adjacent surface, for example, may be optically clear. The stripe may extend, for example, downwards from the application surface prior to first use of the product but end between 5% and 20% above the lower end of the composition.

In a second aspect, the product also includes a platform within the container. Typically, the platform is threadedly engaged with a threaded shaft such that when the shaft is rotated, for example by rotating a turnbuckle or like component positioned at the bottom of the product, the platform moves towards the open end of the container, thereby pushing out the composition. The composition has an upper portion and a lower portion and the lower portion has a different composition than the upper portion. When the lower portion becomes exposed at the open end of the container, it provides a different visual appearance on the application surface than the upper potion.

In a third aspect, the product includes a usage indicator that provides a visual indication that a predetermined portion of the composition has been consumed.

In a fourth aspect, the application surface includes a stripe extending downwardly prior to first use. The composition also includes a thin line parallel to the stripe extending upwards from the end of the composition. "Different color", as used herein, includes different shades of a color.

White and black are considered colors. A change in pearlescence is considered a different color.

"Within the container", as used herein, means that at least part of the composition is within the container; for example, when the upper end of the composition including the application surface extends above the container the composition still is considered "within the container".

Other aspects of the invention include applying the antiperspirant and/or deodorant product to the underarm in an amount effective to reduce perspiration and/or malodor and to methods of making the products. Other features and advantages of the invention will be apparent from the description of the embodiment thereof, and from the claims.

DETAILED DESCRIPTION Referring to Figs, la and 2a, prior to first use product 10, which may be an antiperspirant or deodorant product, includes a container 12 and a composition within the container having domed application surface 14 and lower end 16. The bottom of the container includes a platform 17 for advancing the composition upwards through the container. The composition includes portion 18 and striped portion 20 having a width, for example, of at least 0.1 inch and preferably between 0.2 inch and 0.5 inch. In product 10 striped portion 20 has a width of 0.25 inch. Striped portion 20 extends about 90% of the distance from application surface 14 towards lower end 16. Portions 18 and 20 have different compositions and portion 20 has a different color than portion 18. For example, portion 20 may be dark blue, light blue, dark green, or light green, and portion 18 may be white or vice versa. Application surface 14 alternatively can be flat. Referring to Figs, lb-le and 2b-2e, as product 10 is used the composition is consumed. Bottom end 22 of striped portion 20 moves closer to the newly established application surface. Eventually, bottom end 22 reaches a newly established application surface (see Figs. Id and 2d), and the application surface visually changes in appearance (see Fig. 2d) and provides the user with a visual indication that the product 10 has largely been consumed. Other multiple portion antiperspirant and/or deodorant compositions are described and illustrated in U.S.S.N. 09/784,488, filed February 15, 2001, which is owned by the same owner as the present application and is hereby incorporated by reference.

One or both of portions 18 and 20 of the composition discussed above may include an antiperspirant or a deodorant active. The antiperspirant or deodorant active may either be dissolved or suspended in a dermatologically acceptable vehicle. The vehicle may typically include a volatile silicone or a polyhydric alcohol. Typically the vehicle will also include a gelling or thickening agent, such as, for example, a high melting point wax or dibenzylidene sorbitol.

The preferred antiperspirant salts are aluminum salts and aluminum zirconium salts. Preferred aluminum salts are those having the general formula Al₂(OH)₆__aX_a wherein X is Cl, Br, I, or NO₃, and a is about 0.3 to about 5, preferably about 0.8 to about 2.5, more preferably about 1 to about 2 (such that the Al to X mole ratio is about 0.9:1 to about 2.1:1). These salts generally have some water of hydration associated with them, typically on the order of 1 to 6 moles per mole of salt. Most preferably, the aluminum salt is aluminum chlorohydrate (i.e. X is Cl in the above formula), especially 5/6 basic aluminum chlorohydrate where a is about 1, such that the aluminum to chlorine mole ratio is about 1.9:1 to 2.1:1. Aluminum chlorohydrate is referred to as "ACH" herein.

Preferred aluminum-zirconium salts are mixtures or complexes of the above-described aluminum salts with zirconium salts of the formula ZrO(OH)₄._pbY_b wherein Y is Cl, Br, I, NO₃, or SO₄, b is about 0.8 to 4, and p is the valence of Y. The zirconium salts also generally have some water of hydration associated with them, typically on the order of 1 to 7 moles per mole of salt. Preferably the zirconium salt is zirconium hydroxychloride of the formula ZrO(OH)₄._bCl_b wherein b is about 0.8 to 4, preferably about 1.0 to about 4. The aluminum-zirconium salts encompassed by the present invention have an Al:Zr mole ratio of about 2 to about 10, and a metal:X+Y ratio of about 0.73 to about 2.1, preferably about 0.9 to 1.5. A preferred salt is aluminum-zirconium chlorohydrate (i.e. X and Y are Cl), which has an Al:Zr ratio of about 2 to about 10 and a metakCl ratio of about 0.9 to about 2.1. Thus, the term aluminum-zirconium chlorohydrate is intended to include the tri-, terra-, penta- and octa-chlorohydrate forms. Aluminum-zirconium chlorohydrate is referred to as "AZCH" herein. Generally, the aluminum-zirconium antiperspirant salts also contain a neutral amino acid such as glycine, typically in an amount to provide a Zr:Gly ratio of about 1:1 to 4:1.

The preferred ACH and AZCH salts are of the enhanced efficacy type. By "enhanced efficacy salt" is meant an antiperspirant salt which, when reconstituted as a 10%> aqueous solution, produces an HPLC chromatogram (as described, for example, in U.S. 5,330,751, which is incorporated herein by reference) wherein at least 50%, preferably at least 70%, most preferably at least 80%), of the aluminum is contained in two successive peaks, conveniently labeled peaks 3 and 4, and wherein the ratio of the area under peak 4 to the area under peak 3 is at least 0.5, preferably at least 0.7, and more preferably at least 0.9 or higher. Particularly preferred, for example, are salts wherein at least 30%>, more preferably at least 40%, of the aluminum is contained in peak 4. The aluminum present in peaks 3 and 4 should be of the Al^c type, not Al^b, when analyzed by the ferron test. Enhanced efficacy aluminum chlorohydrate is referred to as "EACH" herein. Enhanced efficacy aluminum-zirconium chlorohydrate is referred to as "EAZCH" herein.

An alternative enhanced efficacy antiperspirant salt are those described in U.S.S.N. 09/696,271, filed on October 25, 2000, which has been assigned to the same assignee as the present application and is hereby incorporated by reference. Examples of these salts are aluminum-zirconium tetrachlorochlorohydrate or aluminum-zirconium octochlorohydrate with an HPLC peak 5 area content of at least 45%. These enhanced efficacy salts will be referred to as "E⁵AZCH" herein.

In this application, weight percent (USP) of antiperspirant salt is calculated as anhydrous weight percent in accordance with the U.S.P. method. This calculation excludes any bound water and glycine. For aluminum chlorohydrate and aluminum-zirconium chlorohydrate, the calculation is as follows:

%ACH = %Al[26.98x + 17.01(3x-l) + 35.45] / 26.98x where x=Al/Cl ratio; %AZCH = %Al{26.98y + 92.97 + 17.01 [3y+4-(y+l)/z] + 35.45(y+l)/z} / 26.98y where y=Al/Zr ratio and z=metal/Cl ratio.

For reference purposes, calculation of antiperspirant salt weight percent in accordance with the U.S.P. method compares to the previously used > »

¹ - 7 - standard industry method is as follows: 50% ACH (std.) approximately = 40.8% (USP); 50% AZCH (std) approximately = 38.5% USP.

A portion or both portions of the antiperspirant composition includes the antiperspirant salt in a perspiration reducing effective amount (typically at a concentration of about 3%ι to about 25%> USP active, more typically about 8% to about 22% USP active).

The above list of materials is by way of example only and is not intended to be a comprehensive list of all potential antiperspirant stick components. Other low melting waxes, non-volatile emollients and suitable components are readily identifiable to those skilled in the art. Of course, other ingredients such as colloidal silicas, particulate polyolefins, talcum materials, fragrances, colorants and preservatives may also be included as desired. For example, the composition may include up to about 10%o fragrance or about 2%> colorant by weight. Deodorant active ingredients may also be included as desired. A suitable deodorant active is any agent that inhibits, suppresses, masks or neutralizes malodor. These may include (1) antimicrobial or bactericidal agents which kill the bacteria responsible for malodor production, (2) agents which inhibit or suppress or interfere with the bacterial enzymatic pathway that produces malodor, and (3) agents which mask or absorb or neutralize malodor.

The aromatic rings in each benzylidene group may be unsubstituted or substituted, as described in U.S. Pat. No. 5,200,174, which is incorporated herein by reference. When substituted, it is preferred that the benzyl ring contain an electron withdrawing group at the meta position. Typical substituted compounds include di(metafluorobenzylidene) sorbitol and di(meta-chlorobenzylidene) sorbitol. The preferred gelling agent is dibenzylidene sorbitol (DBS).

The composition may also include one or more of other ingredients discussed previously.

One or both of the portions of the composition may be in the form of a water-in-oil emulsion comprised of an aqueous phase including the antiperspirant salt and an oil phase including a volatile silicone. This is an alternative approach for providing a product in which one or both portions are clear. Clarity is achieved by matching the refractive index of the water phase with the refractive index of the oil phase. Compositions of this type are described in U.S. Pat. 5,587,153, which is incorporated by reference herein. The water phase may include water and other polar species such as the mono- and polyhydric alcohols including discussed previously. The water phase may comprise, for example, between about 70%> and about 90%> of the composition by weight.

The oil phase may include one or more of the volatile silicones and one or more of the non- volatile silicones discussed previously. The oil phase may comprise, for example, between about 10% and about 30%) of the composition by weight.

Referring to Figs. 3a-3e, an antiperspirant product including the above composition can be prepared by inserting a hollow template 24 into inverted container 12. Hollow section 26 of template is filled with the stripe composition in molten form. After the blue composition has solidified template 24 is removed and the remaining space in the container filled with the outer composition in molten form.

Antiperspirant product 10 can also be prepared by modifying the procedures described in U.S.S.N. 09/784,488, U.S.S.N. 09/784,487, and/or U.S.S.N 09/784,493, all of which were filed on February 15, 2001, have the same owner as the present application, and are hereby incorporated by reference. "Optically clear" as used herein, is defined in these applications. Other examples of antiperspirant compositions and striped portions that can be used in product 10 (with appropriate modification) are described in U.S.S.N. 09/784,488.

Referring to Figs. 4a and 5a, alternative product 28 includes striped portions 30 and 32. Striped portion 30 is positioned like stripe portion 20 (previously described) and extends about 90% of the distance from the application surface to the lower end of the composition. Striped portion 32, which has a different color than striped portion 30, extends from the bottom end of striped portion 30 to the lower end of the composition.

Referring to Figs. 4b-4d and 5b-5d, as product 28 is used the bottom end of striped portion 30 moves closer to the application surface. Eventually, the bottom end reaches the application surface and striped portion 32 begins to become exposed. As a result, the application surface changes in appearance and provides the user with a visual indication that product 28 has largely been consumed.

Other embodiments are within the claims. For example, the visual indication can be provided by a portion that appears for the first time towards the lower end of the composition. For example, the composition may include two thin lines parallel to, and on either side of, a central stripe. The central stripe can extend from the application end to the lower end of the composition, but the parallel lines may extend only a short distance upward from the lower end. Alternatively, the composition may include the thin parallel lines, but no central stripe.

The change in appearance of the composition can be provided by a variety of patterns in addition to a stripe or thin line. The change in appearance can be provided, for example, by a swirl or marbled pattern, or by the inclusion of geometric shapes such as beads, stars, diamonds, etc. The pattern may result, for example, from one portion being optically clear and the other portion being opaque. Referring to Figs. 6 and 7, an alternative product 34 includes a composition including upper portion 36 and lower portion 38, which has a different color than upper portion 36. As product 34 is used, bottom portion 36 moves closer to the application surface and eventually becomes exposed. As a result, the application surface changes in appearance and provides the user with a visual indication the product has largely been consumed. The upper portion of product 34 also can be provided with a central stripe having the same color as the lower portion.

Referring to Figs. 8-11, alternative products 40 and 46 include upper portions 42 and 48, respectively, and lower portions 44 and 50 respectively. The upper and lower portions each have a colored stripe section, but the lateral length of the colored stripe section is different in the lower portion than in the upper portion. The application surface of composition 40 and 46 initially each include a central stripe that extends across the entire lateral length, but then after about 70% of the composition has been consumed the stripe gradually and continuously diminishes in lateral length and eventually disappears. In product 40, the stripe regressively disappears from one side to the other side (much like a fuel gauge), while in product 46 the stripe regressively disappears from both edges toward the middle. In the foregoing description, where the product is referred to as an antiperspirant product, it should be understood that the product may be another type of cosmetic or therapeutic product, such as for example a deodorant product. The composition may be a deodorant composition including two portions or a combined antiperspirant/deodorant composition in which one portion includes an effective amount of a deodorant active ingredient and the other portion includes an antiperspirant salt. Moreover, the composition may include three, four, or even five portions.
