Description

SOLAR FILTERING AND SOLAR FILTERS FOR SKIN CARE COMPRISING ORGANIC MATERIAL IN PARTICLES FIELD OF THE INVENTION The present invention relates to topical compositions with a continuous aqueous phase, suitable for providing high levels of wetting to a product having very acceptable properties upon contact with the skin. More particularly, the invention relates to topical compositions which, in addition to wetting, also provide protection against the damaging effects of ultraviolet radiation, while maintaining optimal skin contact properties. The compositions of the present invention are especially useful for the treatment of the skin of the face and hands, and also of other areas of the body.

BACKGROUND A feature that has long been the subject of various topical compositions, including skin care compositions, is that they contain ingredients that provide benefits of wetting, skin regulation and skin protection.

UV radiation. These compositions are used both to improve the hydration levels of the skin and to protect the skin against the damaging and damaging effects of ultraviolet radiation. In today's environmental environments, when consumers are increasingly exposed to conditions that dry out the skin a lot, such as in buildings with air conditioning and in places where UV radiation is becoming increasingly harmful as a result of the decrease in the ozone layer, there is a growing demand for skin care products, especially facial products, which protect against these harmful daily attacks and repair the damage that this causes. On the other hand, these beneficial agents for the skin, especially organic sun blockers, water-soluble humectants and vitamins, can be very adherent to skin contact, with the result that compositions containing significant levels of these ingredients have undesirable properties in contact with the skin, among them, which are very greasy, sticky and when applied, it creates rub resistance. In addition, when these high levels of humectants are combined with thickeners, adhesion can be exacerbated. Thus, until now, for the formulation of topical compositions the effective levels of the ingredients that impart benefits have had to be sacrificed, having to minimize those levels, so that the final product has acceptable properties on contact with the skin of the patient. consumer. In summary, to date, to get topical compositions they have acceptable properties in contact with the skin, the tendency is that they contain effective ingredients and high adhesion at levels below the optimum, and as a result, to achieve the desired benefits on the skin, multiple applications are required over a prolonged period. Because the ingredients with the worst adhesion properties are often water soluble, this problem is exacerbated in topical compositions having a continuous aqueous phase. This is because the ingredients with high adhesion properties, when present or solubilized within the aqueous phase, reach high levels of contact with the skin, during application. Therefore, it would be good to have a topical composition with a continuous aqueous phase comprising effective levels of ingredients with beneficial properties for the skin, in particular, with benefits of wetting and protection against UV radiation, while at the same time offering to the consumer acceptable properties when in contact with the skin. To date, in the compositions for skin care the inclusion of particulate materials including both organic and inorganic particles has been reported, to affect the texture of both the skin and the composition itself. See, for example, Quantification of the Soft-Focus Effect. Cosmetics & Toilethes, Vol. 111, July 1996, p. 57-61, which states that skin lines can be physically filled with reflective substances, such as T¡O2. U.S. Patent No. 4,892,726, issued to Toshiba Silicone Co. Ltd, describes the use of powdered polimetilsilsesquioxane in cosmetic and makeup compositions, which are uniform after applying and impart a natural color. These particles are already available in a vapedad of particle size degrees, from Toshiba Silicone Co. Ltd under the name Tospearl®. WO 00/24372 discloses topical compositions comprising from 0.5% to 25% of a particulate material having a refractive index of 1.35 to 1.6 and a particle size of 2μm to 30μm, together with other active ingredients that improve the appearance , such as, for example, vitamin B3 compounds and retinoids, to impart a visual improvement to the skin. The particles shown herein include, similarly, Tospearl® 145A having a median particle size of about 4.5μm. Similarly, the co-pending application PCT / US99 / 04748 presents topical compositions comprising from 0.1% to 10% of organic particulate material, again with a refractive index of 1.3 to 1.7, which are suitable for imparting an essentially immediate improvement in the appearance and contact with the skin. EP-A-692,242 discloses the use of deformable hollow particles with a size of 1 to 250 μm, more preferably 18 μm, to reduce the sticky feel of essentially anhydrous compositions that are rich in fatty substances; EP-A-908,175 presents stable cosmetic compositions comprising at least one fatty phase, cross-linked elastomeric organopolysiloxanes and high levels of organopolysiloxane particles; and the EP-A-790,055 discloses the use of organosi loxane, elastomeric, cross-linked polymers in combination with a fatty phase and, preferably, contained within a fatty phase, to prepare compositions that provide a matte appearance to the skin. These applications present a variety of cosmetic compositions with improved contact properties with the skin and which additionally has better appearance properties in the skin. However, the applications do not present aqueous compositions with very effective levels of agents that provide benefits of wetting and protection against UV radiation. The compositions and exhibitions of the prior art provide useful advances in the technique of cosmetic treatment of the skin, such as in the use of organic particles together with agents that provide benefits to the skin, in the so-called so-called skin-beneficial agents. However, they do not adequately teach the manner of providing both effective levels of ingredients for skin moistening and for protection against UV radiation in a water-based topical composition, which also has acceptable properties on contact with the skin of the skin. consumer. It has been surprising that the negative aspect of high adherence of topical skin care compositions having an aqueous continuous phase and also containing very effective levels of ingredients for the skin has now been discovered.

Wetting and protection against UV radiation can be reduced by including, within the composition, one or more types of organic materials into additional particles, with a defined particle size and a critical surface tension. It is important to note that the improvements in skin contact properties are so considerable that high levels of wetting can be achieved in a formulation together with the protection against UV radiation derived from organic materials. Previously, these combinations would not have been possible due to unacceptable adhesion. In addition, it has also been found that if the organic particulate is previously mixed in a low viscosity organosiloxane oil, the improvements achieved in the skin contacting properties are even greater. Without wanting to be limited by theory, it is believed that the inclusion of particulate materials helps to minimize friction when applying the product. With the application of the product, the particles are located in the waste interface of the product / air, protruding from the surface of the product residue. In this way, the contact of the skin with the residue of the product is minimized and the perception on the skin is improved. To ensure that the particulates are delivered in the most efficient manner to the surface of the skin during application it is preferred that the particulate be pre-mixed in a carrier oil. The particles are completely wetted by the carrier oil and the low viscosity and, therefore, the High mobility of the premix ensures that the particles spread efficiently on the surface of the skin when the product is applied. An object of the present invention is to provide topical compositions having a continuous aqueous phase suitable for imparting to the skin high levels of wetting and protection against UV radiation. Another object of the present invention is to provide topical compositions containing a particulate material, for example, polymethylsilyesquioxane, which neutralizes the adhesion of the formulations to provide the desirable skin contacting properties. Still another object of the present invention is to provide compositions that are useful for providing the desired levels of wetting and protection against UV radiation without the need for multiple applications. These and other objects of this invention will be apparent in the light of the following discussion.

The compositions are useful for imparting very effective levels of wetting and protection against UV radiation, while maintaining acceptable skin contacting properties. This invention also relates to manufacturing methods for increasing the benefits of skin contact and cosmetic methods to provide the benefits of wetting and protection against UV radiation by topical application of the present compositions.

DETAILED DESCRIPTION OF THE INVENTION All percentages and prtions used herein are expressed by weight of the total composition and all measurements made were made at 25 ° C, unless otherwise indicated. Unless otherwise indicated, all percentages, prtions and levels of the ingredients referred to herein are based on the actual amount of the ingredients and do not include the solvent, fillers or other materials that can be combined with the ingredient in products that are commercially available. All publications cited herein are considered fully incorporated into this description, as a reference, unless otherwise indicated.

The term "safe and effective amount", as used herein, refers to an amount of a compound, component or composition, sufficient to positively induce a positive benefit, preferably, the positive benefit of skin appearance or Skin contact properties, which independently includes the benefits stated herein; however, that amount is low enough to avoid serious side effects, that is, to provide a reasonable risk / benefit ratio within the reach of judicious medical judgment. The active ingredients, as well as other useful ingredients herein, can be categorized or described herein by their cosmetic or therapeutic benefits or by their described form of action. However, it will be understood that the active ingredients, as well as other Useful ingredients herein may, in some cases, provide more than one cosmetic or therapeutic benefit or operate by more than one form of action. Therefore, the classifications herein are made for reasons of convenience and are not intended to limit an ingredient to the particular application indicated or to the applications listed. The elements of these compositions are described below in greater detail.

Essential elements of composition Organic material in particles The composition comprises approximately between 0.01% and 25%, preferably approximately between 0.1% and 15%, more preferably between 0.2% and 5%, of the organic particulate material. What is most preferred is that the organic particulate material has a median particle size of between about 0.5 and 30 μm, preferably about 0.5 to 15 μm, more preferably about 0.7 to 10 μm and with a preference superlative of approximately between 1 and 7.5μm. The median particle size refers to the particulate material in its pure form, that is, in its essentially pure powder form. However, methods intended to measure particle size require that the particulate material be disperse in an inert carrier, for example, pure oil, to measure the particle size distribution. The median particle size can be determined by any method known in the art, such as the use of Coulter counter equipment or the ASTM standard Designation E20 85"Standard Practice for Partial Size Analysis of Particulate Substances in the Range of 0.2 to 75 Micrometers by Optical Microscopy "(Standard practice for the analysis of particulate substances in the range of 0.2 to 75 micrometers by optical spectroscopy), Volume ASTM 14.02, 1993. It is preferred that more than 50%, preferably, more than 60% and, with greater preference, more than 70% of the particles are within the ranges prescribed by the respective median values. Preferred particles are free flowing solid materials. By the term "solid" it is meant that the particles are preferably neither deformable nor elastomeric. The particles are selected from polymers of organosilicon, polyethylene, polyacrylonitrile, polyacrylic acid or derivatives thereof, polymethacrylic acid, polystyrene, polytetrafluoroethylene (PTFE), poly (vinylidene chloride), polyamide and mixtures thereof. More preferably, the organic particulate material is selected from organosilicon polymers and mixtures thereof and, with an even greater preference, from polymethyl silsesquioxane. Copolymers derived from monomers of the aforementioned materials can also be used. Suitable and commercially available examples of the organic particulate material of polymethylsilsquioxane are Tospearl® 145 which has a median particle size of approximately 4.5 μm and Tospearl® 1320 which has a median particle size of 12 μm. A further representative example and commercially available is Fluoropure 100C from Shamrock Inc, which is an organic particulate material of polytetrafluoroethylene. Another representative and commercially available example is the EA-209® from Kobo, which is a copolymer of ethylene and acrylic acid having a median particle size of about 10 μm. The organic particulate material preferably has a critical surface tension less than 50 mN / m, preferably less than 40 mN / m and, more preferably, less than 35 mN / m. Critical surface tension is defined by Drew and Myers in "Surfaces, Interfaces and Colloids, Principles and Applications" 1991 chap. 17, pgs. 364-369, (VCH Publishers Inc, New York) and it is measured, without a doubt, thanks to the measurements of the contact angle of a series of liquids related to different surface tensions, as also described in the aforementioned reference.

Humectants The compositions of the present invention comprise from about 8% to 30%, preferably, from about 8.5% to 20% and, more preferably, from about 9% to 15% in weight, of humectant. Preferred humectants include, but are not limited to, selected glycerin, polyoxyalkylene glycol compounds, urea, panthenol D or DL, hexane-1, 2,6-triol, guanidine or its derivatives, alkylene glycols, such as butylene glycol or propylene glycol. Preferred humectants are glycerin, urea and mixtures thereof. The compounds of the above list can be incorporated individually or in combination. The aforementioned compounds can cause high levels of adhesion, especially when they are used in the preferred levels, greater than 8%. However, it has been found that this adhesion sensation can be effectively neutralized by the use of the humectants in combination with the organic particulate materials, as described in the present invention.

Organic sun blockers The compositions of the present invention comprise an organic sunblock. Suitable sunscreens may have UVA-absorbing properties, UVB-absorbing properties or a mixture thereof. The exact amount of active sunscreen will vary, depending on the desired sun protection factor, that is, the "SPF" of the composition, as well as the desired level of protection against UVA radiation. The compositions of the present invention preferably comprise an SPF of at least 10, preferably at least 15 (the SPF is a commonly used measure of the photoprotection of a sunscreen against erythema). The SPF is defined as the proportion of the ultraviolet energy required to produce minimal erythema in a protected skin, with respect to the energy required to produce the same minimum erythema in the unprotected skin of the same person. Refer to Federal Register, 43, no. 166, pgs. 38206-38269, August 25, 1978). The compositions of the present invention comprise between about 2% and 20%, more often between about 4% and 14% by weight, of the organic sunblock. Sunscreens include, but are not limited to, those found in the CTFA International Cosmetic Ingredient Dictionary and Handbook, 7th ed., Volume 2, p. 1672, edited by Wenninger and McEwen (The Cosmetic, Toiletry, and Fragrance Association, Inc., Washington, DC, 1997). The compositions of the present invention preferably comprise an active agent for the UVA-absorbing solar block, which absorbs UV radiation having a wavelength of approximately between 320 nm and 400 nm. Suitable actives of a UVA-absorbing sunscreen are selected from dibenzoylmethane derivatives, anthranilate derivatives, such as, for example, methylanthranite and homomethyl, 1-N-acetylanthranilate and mixtures thereof. In U.S. Patent No. 4,387,089, awarded to Depolo and in Sunscreens: Development. Evaluation. and Regulatory Aspects edited by N. J. Lowe and N. A. Shaath, Marcel Dekker, Inc. (1990) describes examples of dibenzoylmethane sunblock actives. The active agent for Sun block that absorbs UVA radiation is preferably present in an amount such as to provide protection against broad spectrum UVA radiation, either independently or in combination with other UV protective assets that may be present in the composition. The preferred UVA radiation sunscreen assets are the dibenzoylmethane sunblock actives and their derivatives. These include, but are not limited to, those selected from: 2-methyldibenzoylmethane, 4-methyldibenzoylmethane, 4-isopropyldibenzoylmethane, 4-tert-butyldibenzoylmethane, 2,4-dimethyldibenzoylmethane, 2,5-dimethyldibenzoylmethane, 4,4 ' -diisopropylbenzoylmethane, 4- (1,1-dimethylethyl) -4'-methoxydibenzoylmethane, 2-methyl-5-isopropyl-4'-methoxydibenzoylmethane, 2-methyl-5-tert-butyl-4'-methoxy-dibenzoylmethane, 2, 4-dimethyl-4'-methoxydibenzoylmethane, 2,6-dimethyl-4'-tert-butyl-4'-methoxydibenzoylmethane and mixtures thereof. Preferred dibenzoyl active blocking agents include those selected from: 4- (1,1-dimethylethyl) -4'-methoxydibenzoylmethane, 4-isopropyldibenzoylmethane, and mixtures thereof. An active agent for the most preferred sunblock is 4- (1,1-dimethylethyl) -4'-methoxydibenzoylmethane. The active agent for sun block 4- (1,1-dimethylethyl) -4'-methoxydibenzoylmethane, which is also known as butyl methoxydibenzoylmethane or avobenzone, can be obtained commercially under the names Parsol® 1789 from Givaudan Roure (International) SA (Basel, Switzerland) and Eusolex® 9020 from Merck & Co., Inc. (Whitehouse ion, NJ). Sunblock of 4-isopropyldibenzoylmethane, also known as isopropifibenzoylmethane, is commercially available from Merck, under the name of Eusolex® 8020. The compositions of the present invention preferably further comprise an active agent for solar blocking against UVB radiation, which absorbs UV radiation having a wavelength. approximately between 290 nm and 320 nm. The compositions comprise an amount of the active agent for sunblock against UVB radiation that is safe and effective to provide protection against UVB radiation, either independently or in combination with other active UV protective agents that may be present in the compositions The compositions preferably comprise about 0.1% to 16%, more preferably about 0.1% to 12%, and most preferably about 0.5% to 8% by weight, of the organic sunscreen that absorbs UVB radiation. A wide variety of active agents for sun block against UVB radiation is suitable for use in the present. Exemplary examples of these active agents for sun block, organic, are described in U.S. Pat. 5,087,372 issued on February 11, 1992 to Haffey and others; and U.S. Pat.

Also present in the present are useful salts and neutralized acid forms of acidic sun blockers. When organic sunscreen salts are used in the compositions of the present invention, such as PBSA, they can disturb the action of the thickener, with the result that the final product may have a rheology below optimal. This can be counteracted by the addition of higher levels of thickener, fatty alcohols or nonionic surfactants, in such a way that the rheology of the final product returns to the desired level. To any of the useful compositions of the present invention, an agent can also be added to stabilize the sunscreen against UVA radiation and prevent its photodegradation when exposed to UV radiation and, thus, maintain its protective efficacy against UVA radiation. A wide range of compounds that provide these stabilizing properties have been cited and they must be chosen to comply as a whole with both the solar block against radiation UVA as with composition. Suitable stabilizing agents include, but are not limited to, those described in U.S. Pat. 5,972,316; 5,968,485; 5,935,556; 5,827,508 and in patent WO 00/06110. Preferred examples of stabilizing agents for use in the present invention include: 2-ethylhexyl-2-cyano-3,3-diphenylacrylate (referred to as octocrylene), ethyl-2-cyano-3,3-diphenylacrylate, 2-ethylhexyl-3 , 3-diphenylacrylate, ethyl-3,3-bis (4-methoxyphenyl) acrylate and mixtures thereof.

For example, preferred lotions have an apparent viscosity of between about 10,000 and 40,000 mPa.s; Preferred creams have an apparent viscosity of between about 30,000 and 160,000 mPa.s. The apparent viscosity can be determined using a Brookfield DVU RV viscometer with TD spindle at 5rpm or its equivalents. The viscosity in the composition is determined after it has been allowed to stabilize after preparing it, in general, at least 24 hours, under conditions of ambient pressure and 25 ° C after the preparation of the composition. The apparent viscosity is measured when the composition has a temperature of 25 ° C, after 30 seconds of spindle rotation.

The compositions of the present invention comprise a continuous aqueous phase and, preferably, comprise an oil in water emulsion in which a hydrophobic phase, for example, a lipid, an oil or an oily material, is dispersed within the aqueous phase . In the technology of emulsions, the term "dispersed phase" is a term well known to any person skilled in the art, which means that the phase exists as small particles or droplets that are suspended in a continuous phase and surrounded by it. The dispersed phase is also known as the internal or discontinuous phase. Oil-in-water emulsions often comprise about 1% to 50% (preferably about 1% to 30%) of the hydrophobic dispersed phase and about 1% to 99% (preferably about 40% to 90%) ) of the continuous hydrophilic phase. The emulsion may also comprise a gel network, such as that described in G. M. Eccleston, Application of Emulsion Stabilitv Theories to Mobile and Semisolid O / W Emulsions. Cosmetics & Toiletries.

The known or conventional surfactants can be used in the composition, as long as the selected agent is chemically and physically compatible with the essential components of the composition and provides the desired characteristics. Suitable surfactants include materials that are not derived from silicones and mixtures thereof. All surfactants presented in the application WO 00/24372 can be considered as suitable for the present invention. The compositions of the present invention preferably comprise approximately between 0.05% and 15% of a surfactant or mixtures of surfactants.
