Description

COMPOSITIONS HAVING A SUNSCREEN FOR USE IN PERSONAL CLEANSING PRODUCTS

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to compositions having a sunscreen. The composition is used to make personal cleansing products, such as, for example, cleansing bars, body and facial washes, shower gels and shampoos. More particularly, the present invention relates to personal cleansing products, such as a cleansing bar, a body and/or facial wash or a hair shampoo, that provide cleansing activity and sunscreen protection.

2. Description of the Prior Art

It has been recognized that exposure to ultraviolet radiation has deleterious effects on the skin. UV radiation has been linked to photoaging of the skin, resulting in undesired changes in the appearance of the skin, such as wrinkling and sagging. Exposure to UV radiation has even been linked to the more serious skin cancers, such as melanomas.

Accordingly, users have desired novel products that provide protection from UV radiation yet require a minimal amount of application time. Bathing provides an opportunity to efficiently apply effective sunscreen protection, especially in the United States where many users begin their day with a shower. Although, there have been attempts to incorporate sunscreens in cleaning compositions, heretofore such prior art sunscreen cleansing products have been liquid cleansing products, some of which require elaborate and, thus, expensive packaging. (See U.S. Patent No. 5,612,307 to Chambers et al.) Other prior art cleansing sunscreen compositions have failed to provide an effective cleansing/sunscreen bar that is commercially feasible to manufacture.

U.S. Patent No. 4,704,321 to Bernstein provides a liquid detergent with a sunscreen agent. However, the Bernstein formula fails to provide a personal cleansing composition that has been clinically shown to provide an SPF greater than 1.6, much less greater than 5. Furthermore, the Bernstein patent fails to provide a personal cleansing bar that includes a sunscreen or a method of producing such a cleansing bar.

U.S. Patent No. 4,954,332 to Bissett, et al. discloses photoprotective compositions comprising tocopherol sorbate and an anti- inflammatory. However, the Bissett et al. patent specifically distinguishes between pharmaceutical/cosmetic compositions, which may include sunscreens, and cleansing compositions, which are not disclosed as including sunscreens.

PCT publication WO 98/14559 discloses in Table III a bar composition having 5% octyl methoxycinnamate incorporated therein (Formula 205). However, the foregoing bar composition was evaluated only for the effect of the sunscreen component on the overall transparency of the bar composition. The efficacy, if any, of the bar composition in providing sunscreen protection was not evaluated. Although a clinical evaluation of the Formula 205 soap bar would likely fail to demonstrate an effective SPF since the Formula 205 soap bar fails to provide any agents that assist in preventing the sunscreen from being washed from the skin. BRIEF SUMMARY OF THE INVENTION

It is an object of the present invention to provide a composition having a sunscreen that is used in personal cleansing products, such as cleansing bars, body and facial washes, shower gels, and shampoos.

It is another object of the present invention to provide such a personal cleansing product for topical use that provides effective sunscreen protection.

It is yet another object of the present invention to provide such a personal cleansing bar that provides a sunscreen protection factor of greater than about 1.6.

It is a further object of the present invention to provide a process for making such a personal cleansing bar.

These and other objects of the present invention, in brief summary, are achieved by providing a personal cleansing composition that comprises a vehicle, a sunscreen and a film former, and by providing a process of preparing a personal cleansing bar from the foregoing composition by incorporating an absorbing agent.

DETAILED DESCRIPTION OF THE INVENTION

The personal cleansing composition or product of the present invention basically comprises a vehicle, a sunscreen, and a film former. The composition may include other ingredients, such as, for example, a fragrance and a color. All percentages set forth herein are weight percentages of the final composition unless otherwise specified.

The vehicle is any type of vehicle that is compatible with a surfactant or with surfactant systems, and can be topically applied. It is preferred that the vehicle is a cleansing base. The cleansing bases most commonly used to manufacture personal cleansing products are soap bases, detergent or "syndet" bases or "combo" bases. ("Combo" bases, as the term indicates, comprise a combination of both syndet and soap bases.) In general, most such cleansing bases have a pH from about 4.5 to about 10.5. As known in the art, soap bases, generally have a higher pH than syndet bases. Soap bases generally have an average pH from about 10 to about 10.5. A superfatted soap base generally has an average pH of about 9 to about 9.5. Syndet bases have lower pH ranges than soap bases and are, thus, the more preferred bases for providing personal cleansing compositions having a pH similar to the pH of skin, about 4.5 to about 7.4. As can be expected, "combo" bases generally have an average pH that is intermediate syndet bases and soap bases, generally from about 7.5 to about 10.0. When the cleansing base is a syndet base, it is preferred that the cleansing base contains sodium cocoyl isethionate.

When one of the primary objectives in practicing the present invention is to provide a cleansing composition having a pH from about 4.5 to about 7.4, a syndet cleansing base is the preferred cleansing base. However, when one of the primary objectives in practicing the present invention is to provide cleansing bars in mass quantities for commercial use using conventional soap making machinery, the preferred cleansing base is the "combo" base.

When the personal cleansing product is a cleansing bar, one example of a preferred cleansing base has from about 40 wt% to about 50 wt% of sodium cocoyl isethionate, preferably in powder form; from about 10 wt% to about 20 wt% free fatty acid; from about 10 wt% to about 20 wt% of a combination of sodium stearate and sodium cocoate; from about 4 wt% to about 7 wt% water; from about 2 wt% to about 10 wt% sodium isethionate; and up to about 5 wt% sodium vinyl sulfonate. A preferred cleansing base for the cleansing bar and body wash embodiments of the present invention is JORDAPON SB-II, a syndet base manufactured by BASF Corporation. Other suitable cleansing bases for use in the present invention are high active sodium cocyl isethionate solids (a non-limiting example is available from Finetex Corporation under the tradename "TAURANOL 1-78") and high active sodium methyl cocyl taurate solids (a non-limiting example is manufactured by Finetex Corporation under the tradename "TAURANOL WS H.P.").

A second, more preferred, example of a cleansing base for formulating cleansing bars of the present invention has from about 30 wt% to about 70 wt%, preferably from about 50 wt% to about 55 wt%, of sodium cocoyl isethionate in powder form; from about 5 wt% to about 15 wt%, preferably from about 8 wt% to 12 wt% stearic acid, which is preferably triple pressed; and from about 1 wt% to about 10 wt%, more preferably from about 2 wt% to about 4 wt%, sodium isethionate. The remainder of this preferred cleansing base may include from about to 1 wt% about 3 wt% PEG-1000; from about 4 wt% to about 6 wt% water; from about 0.1 wt% to about 2 wt% sodium chloride; and from about 3 wt% to about 10 wt% maltodextrin (a non-limiting example being MALTRIN M-100, available from Grain Processing Company).

A third example of a preferred cleansing base includes from about 25 wt% to about 55 wt%, more preferably from about 35 wt% to about 45 wt% of a conventional soap base that comprises about 85% tallow and about 15% coconut oil; from about 25 wt% to about 55 wt%, more preferably from about 35 wt% to about 45 wt% sodium cocoyl isethionate, preferably in powder form. This preferred cleansing base may also include from about 0.1 wt% to about 2.0 wt% titanium dioxide. In addition, while most conventional soap making processes remove some or all of the glycerin formed, the cleansing base of the present invention can include up to 10 wt% of glycerin. This feature greatly reduces commercial costs associated with glycerin removal. When the personal cleansing product is a shampoo, it is preferred that the cleaning base also has either a salt of an alkyl ether sulfate, a salt of an alkyl sulfate, a polyglucoside, or any mixture thereof. It is more preferred that the salt of the alkyl ether sulfate is a salt of lauryl ether sulfate. It is more preferred that the salt of the alkyl sulfate is a salt of lauryl sulfate. It is more preferred that the polyglucoside is lauryl polyglucose (a non-limiting example is available under the tradename "PLANTAREN" from Henkel Corporation). The preferred salts are sodium salts, ammonium salts or triethanolamine ("TEA") salts. When the personal cleansing product is a face and/or body wash (i.e. a liquid personal cleansing product, and not a cleansing bar), it is preferred that the cleansing base has sulfosuccinates, amphoterics, imidazolines, polyglucosides, or mixtures thereof. The preferred polyglucoside is lauryl polyglucose.

The cleansing composition of the present invention includes a sunscreen that is compatible with the chosen vehicle or a cleansing base. The composition includes a sunscreen.

When a salt of the sunscreen is suitable for use in the present invention, as indicated above, the salt may be an organic salt or an inorganic salt. Organic and inorganic salt equivalents to the sunscreens indicated above are known in the art.

Sunscreens have varying optimal pH ranges. Accordingly, the choice of the sunscreen or sunscreen component will depend upon the pH of the vehicle used. However, it is preferred that the sunscreen is selected from the following group: octocrylene, octyl methoxycinnamate, octyl salicylate, oxybenzone, homomenthyl salicylate, butylmethoxy dibenzoylmethane, and mixtures thereof. It is more preferred that the sunscreen is oxybenzone, octyl methoxycinnamate, octocrylene, or any mixture thereof.

It is preferred that the sunscreen is a mixture of two or more sunscreens. It is further preferred that the sunscreen provides both UVA and UVB protection and, thus, it is preferred that the sunscreen includes both an UVA sunscreen and an UVB sunscreen. In addition, when the personal cleansing composition includes a colorant, it is preferred that the sunscreen includes sulsiobenzone as a photostabilizer.

The third component of the composition is a film former. The film former is a waterproofing film former that provides adhesion properties for the sunscreen so that the sunscreen will adhere to the skin during, and remain adhered after, the rinsing process. Any known waterproofing film former that is known in the art to be compatible with a sunscreen and the cleansing base, and that can be topically applied, would be suitable for use in the present invention. Table 2 sets forth preferred waterproofing film formers for use in the present invention, and the corresponding preferred and more preferred ranges for each.

It is also contemplated that the personal cleansing composition of the present invention may be used to topically deliver other active ingredients in addition to the sunscreen agent. For example, during the summer months, a personal cleansing product that provides both insect repellent protection and sunscreen protection would be desired. Examples of insect repellents that may be incorporated into the present invention include: N,N-diethyltolumide (DEET), citronella, ethyl butylacetylaminopropionate (a non-limiting example is available from Merck Industries under the trade name "IR3535"). In areas where mosquito-borne and tick-borne diseases are concerns, a personal cleansing product with a sunscreen and DEET and/or ethyl butylacetylaminopropionate. However, such a personal cleansing product would not be suitable for the washing certain areas of the face, particularly around the eyes. The personal cleansing product can include from about 0.3 wt% to about 30 wt% insect repellent. To accommodate the inclusion of the insect repellent, the content of ingredients, such as the cleansing base and/or the sunscreen could be decreased accordingly.

When the personal cleansing composition is formed using conventional and commercial machinery into a cleansing bar, an absorbing agent must be added. Previously, attempts to make cleansing bars using conventional soap making machinery failed because the addition of the sunscreen created a composite that was too "sticky" to process. Such previous attempts failed to provide a process of making, and particularly stamping, such cleansing bars that was commercially viable.

It has been found that the addition of an absorbing agent, such as talc, sodium cocoyl isethionate powder or other ingredients that have a physical appearance similar to talc, such as starch or oat flour, to absorb the sunscreen so that the composite may be processed through conventional cleansing bar machinery. Sodium cocoyl isethionate powder is particularly preferred because it performs the triple functions of (1 ) absorbing the sunscreen to decrease the "stickiness/tackiness" of the composite, (2) decreasing the pH of the composite to increase the stability of the sunscreen, which is often unstable at higher pH values, and (3) foaming/surfactant action. Thus when the absorbing agent is sodium cocoyl isethionate (powder), the ranges are as previously set forth above. However, when the absorbing agent is a material that provides only an absorbing function, such as with talc, then the cleansing base comprises from about 2 wt% to about 20 wt%, and more preferably from about 5 wt% to about 10 wt%. EXAMPLE 1 Sample milled cleansing bars ("sample A cleansing bars") were manufactured by conventional milled soap making methods on conventional soap making equipment.

The cleansing base used to make the sample A cleansing bar is a syndet cleansing base available from BASF Industries, Inc. under the tradename JORDAPON SB-II Syndet Base, ("the sample A cleansing base") The sample A cleansing base has from about 40 wt% to about 50 wt% of sodium cocoyl isethionate, from about 10 wt% to about 20 wt% free fatty acid, from about 10 wt% to about 20 wt% sodium stearate/sodium cocoate, from about 4 wt% to about 7 wt% water, from about 2 wt% to about 10 wt% sodium isethionate, and up to about 5 wt% sodium vinyl sulfonate. The sample A cleansing base has a pH about 7.4.

The sample A cleansing base was added to a mixer along with 7 wt% of the sunscreen, ethylhexylmethoxycinnamate, and 3 wt% of the waterproofing film former, a PVP/Eicosene copolymer ("GANEX® V-220"). Then, color and fragrance additives were added. Thereafter, the composite was mixed and then milled, to form a homogeneous mass. The homogenous mass was then extruded, cut into billets and stamped into rectangular bars.

The sample A cleansing bar was then subjected to the following test procedure.

The sample A cleansing bar was lathered with warm water in the hands of the user. After the aforementioned lathering period, the user applied the lather to the test area and rubbed the lather onto the test area for fifteen seconds. The test area was the lower back of human subjects. After the completion of the application, the test area was rinsed with warm water for five seconds and then patted dry with a cloth towel. The application was then allowed to "air dry" for an additional two minutes, after which the test area was subjected to UV radiation exposure from a 150 watt xenon arc light source. The Sunscreen Protection Factor (hereinafter "SPF") was measured according to the Sunscreen Product Testing Procedures for Determination of the Sun Protection Factor (SPF) Value and Related Labeling Claims as set forth by the Food and Drug Administration in Sunscreen Drug Products for Over the Counter Human Drugs - Proposed, Safety, Effective and Labeling Conditions, (Federal Register Department of Health, Education and Welfare, Food and Drug Administration, August 25, 1978, Part II.) The sample bar provided a clinical SPF value of about 1.6.

EXAMPLE 2 Cleansing bars having following formula were made and tested as set forth below. A Mazzoni continuous extrusion line having one amalgamator, two Simplex plodders having 2.0 mm screens and a Duplex vacuum plodder having a 3.0 mm screen was used. In addition, a SAS Mariani Tommaso cutter and a Weber Seelander Press were used to cut and press the soap bars. However, other screen sizes and/or equipment known in the art may be used to prepare cleansing bars of the present invention. SAMPLE B

The Sample B cleansing base was prepared as follows. The soap base (comprising about 85% tallow and about 15% coconut oil), sodium cocoyl isethionate (powder) and titanium dioxide were added into the amalgamator (mixer) at room temperature. The sunscreen/film former, having been uniformly mixed at 38°C in a separate container, was added to the Sample B cleansing base in the amalgamator. The amalgamator was turned on and the entire composite was mixed for five minutes.

After the five-minute period, the amalgamator was stopped, and the composition was discharged onto a conveyor belt that led to a first Mazzoni Simplex plodder. Although the composite was "sticky" in comparison to conventional composite mixtures not including such a sunscreen/film former mixture, no added difficulty was experienced in transferring the composite, via the conveyor belt, to the first Simplex plodder. Cleansing bars (hereinafter "sample B cleansing bars") were then formed according to conventional methods.

The sodium cocoyl isethionate and stearic acid were added to the Patterson mixer, and the mixer motor was turned on. After the sodium cocoyl isethionate and stearic acid formed a fluid composite, the PEG-1000 was added to the composite. Separately, the sodium chloride was added to the water, mixed and then the sodium chloride/water mixture was added to the composite. Then, the sodium isethionate was added to the composite to be immediately followed by the addition of the Maltodextrin. This composite was mixed 10 minutes at about 82°C. After the 10 minute mixing period, the sunscreen/film former additive was added, and the composite was mixed for an additional 40 minutes at about 78°C to about 82°C before being discharged from the mixer. The hot composite was then processed over a "chill roll", and prepared into bar form on conventional laboratory extrusion equipment.

CLINICAL TESTING

Both sample B cleansing bars and sample C cleansing bars were evaluated on a three-person panel according to the procedure set forth in Example 1. The results are set forth in Table 3 below.

In addition, sample B cleansing bars were subjected to temperatures of about 40°F and about 110°F for one month to determine the stability of the sunscreen component. No significant decrease in concentration occurred for any of the three sunscreens (benzophenone-3, octocrylene and octylmethoxycinnamate) It is contemplated that other active ingredients may be added to the cleansing compositions of the present invention. For example, one or more of fragrances, moisturizers, emollients, superfatting agents, vitamins, keratolytics, skin whitening ingredients, anti-acne agents, anti- bacterial agents may be incorporated into the cleansing compositions of the present invention. Exemplary anti-bacterial agents include TRICLOSAN, available from Ciba-Geigy, and trichlorocarbanilide, available from Monsanto Corporation. An exemplary superfatting agent comprises from about 5 wt% to about 10 wt% coconut fatty acids. To accommodate such active ingredients, the sunscreen or, more preferably the cleansing base, can be decreased accordingly.

The present invention is not limited to the examples illustrated above, as it is understood that one of ordinary skill in the art would be able to utilize substitutes and equivalents without departing from the scope of the present invention.
