Description

COMPOSITIONS CONTAINING SELECTIVE POLYOLIC FLUID ACID LIQUID POLYESTERS TECHNICAL FIELD The present invention relates to compositions suitable for topical application to hair or human skin, which comprise a select combination of polyol fatty acid polyesters having a melting point between -30 ° C and 30 ° C and solid oils which They have a melting point above 30 ° C.

BACKGROUND OF THE INVENTION For many years, topical compositions containing emollients have been used for the treatment of human hair or skin. For example, occlusive hydrocarbons, such as petrolatum, have been used as topical emollients to provide a protective film on human skin to prevent the loss of water into the environment. Petrolatum has also been used in hair care products such as conditioners and grooming aids. However, the most effective and most widely used compositions contain occlusive emollients that exhibit negative aesthetic qualities such as tackiness and greasiness.

In addition, some occlusive emollients that are used to provide a protective film on the skin result in the clogging of the pores of the skin and prevent the flow of oxygen. This obstruction of the surface of the skin or blocking of the passageway or of the circulation of air and moisture limits the use of such heavy occlusive emollient materials. Additionally, European Patent No. 458, 600 B1, published on March 2, 1994, discloses skin care occlusive compositions containing a polyol fatty acid polyester having at least 4 free hydroxyl groups, of which at least 60% are esterified with one or more fatty acids having 8 to 22 carbon atoms which can form an occlusive film on the skin after topical application thereon. U.S. Patent No. 5,160, 738, to Macaulay et al., Issued November 3, 1992, further discloses occlusive compositions containing a combination of two or more polyol fatty acid polyesters which have the appearance and physical properties of petrolatum. However, these compositions also have the disadvantage of being heavy and can clog the pores of the skin by preventing the flow of oxygen. It has now been discovered that compositions containing occlusive emollients can be formulated without being heavy, sticky or greasy. These compositions contain a select combination of polyol fatty acid polyesters having a melting point of -30 ° C to about 30 ° C, and solid oils having a melting point above 30 ° C, and such compositions are They can be applied in a variety of products to provide both efficacy and aesthetic benefits. It is therefore an object of the present invention to provide a composition having effective emotion and acceptable aesthetic qualities, and which contains an occlusive emollient used in combination with a solid oil. It is also an object of the present invention to provide topical compositions containing polyol fatty acid polyesters which are not heavy, sticky or greasy, and which are effective in the treatment of human skin or hair.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a composition suitable for topical application to the human skin or hair, which comprises a polyol polyester fatty acid polyester having a melting point of -30 ° C to about 30 ° C, and a solid oil other than the solid polyol fatty acid polyester having a melting point above 30 ° C to about 250 ° C, wherein said liquid polyol fatty acid polyester has a polyol portion and at least a portion of fatty acid, the polyol portion having at least four free hydroxyl groups wherein at least 60% of these free hydroxyl groups are esterified with one or more fatty acid portions having from 8 to 22 carbon atoms.

The preferred composition further comprises a topical vehicle for the polyol polyester fatty acid polyester and the solid oil combination. All percentages and ratios used herein are by weight and all measurements made at 25 ° C, unless otherwise stated. The invention may comprise, consist of or consist essentially of, the essential as well as optional ingredients and components described herein.

DETAILED DESCRIPTION OF THE INVENTION The term "topical composition" as used herein means a composition suitable for topical application to human skin or hair. The term is used to encompass a wide variety of compositions for personal care, beauty care and cosmetic. Non-limiting examples of topical compositions include lotions, creams, hand and body lotions, skin conditioning lotions and creams, skin protecting compositions, sun blocking compositions, fading creams, anti-acne compositions, products for the renewal of the skin, non-foaming cleansing lotions, moisturizers, facial moisturizers, makeup, foundation, lipstick, lip protectors, skin cleansers, hand cleaners, face and body, shower products, shampoos and the like.

The term "topical vehicle", as used herein, is well known to those skilled in the art and means one or more diluents or liquid or solid filler vehicles that are suitable for administration to a human. The term "compatible", as used herein, means that the components of the topical vehicle can be mixed with the components of the present invention and with each other, in such a way that there is no interaction that can substantially reduce the effectiveness or aesthetics of the cosmetic composition under ordinary situations of use. The topical vehicle must be a pharmaceutically acceptable vehicle. The term "pharmaceutically acceptable" as used herein, means that the topical carrier must be of a sufficiently high purity and must be suitable for use when placed in contact with human skin or hair without undue toxicity, incompatibility, instability, allergic response and the like. The melting point of the polyol fatty acid polyesters and solid oils can be determined using conventional techniques. Such techniques are well defined in the art, and include thermometric as well as calorimetric methodology. A particularly preferred technique for determining the melting point is described in the patent E.U.A. No.5, 306,514 for Letton et al., Issued April 26, 1994, which is hereby incorporated by reference in its entirety. This technique typically involves the measurement of melting points using differential scanning calorimetry (DSC) where a sweep temperature of 5 ° C / minute is used to measure the melting point. The melting point is the temperature at the intersection of the baseline, that is, the specific heat line, with the line tangent to the trailing edge of the endothermic peak.

Polyethylene liquid polyol fatty acid The composition of the present invention consists of a polyol polyester fatty acid polyester in concentrations ranging from 0.1% to 99.9%, preferably from 0.5% to 75%, most preferred from 1% to 50%, even more preferred from 2% to 25% by weight of the composition. These liquid polyol fatty acid polyesters have melting points below 30 ° C, and are obtained from any aliphatic or aromatic polyol having at least 4 free hydroxyl groups, of which at least 60% of these Free hydroxyl groups are then esterified with one or more fatty acids having from 8 to 22 carbon atoms. Fatty acids can also be described as carboxylic acids, because the terms fatty acid and carboxylic acid are frequently used interchangeably by those skilled in the art. The liquid polyol polyesters used in this invention consist of certain polyols, especially sugar alcohols or sugars, esterified with one or more fatty acid groups. Accordingly, the polyol starting material must have at least 4 esterifiable hydroxyl groups. Examples of preferred polyols are sugars, including monosaccharides and disaccharides and sugar alcohols. Examples of monosaccharides containing four hydroxyl groups are xylose and arabinose and the sugar alcohol obtained from xylose, which has five hydroxyl groups, ie xylitol. The monosaccharide, erythrose, is not suitable in the practice of this invention, since it only contains three hydroxyl groups, but the sugar alcohol obtained from erythrose, ie erythritol, contains four hydroxyl groups and can therefore be used. Monosaccharides containing five appropriate hydroxyl groups are galactose, fructose and sorbose. Sugar alcohols containing 6 hydroxyl groups obtained from the hydrolysis products of sucrose, as well as glucose and sorbose, for example sorbitol, are also suitable. Examples of polyols and saccharides that can be used include maltose, lactose and sucrose, of which all contain eight hydroxyl groups. The polyols used in the polyol liquid esters of the present invention have from 4 to about 12, preferably from 4 to 11, and more preferred from about 4 to 8 hydroxyl groups. The preferred polyols for preparing the polyesters that are used in the present invention are selected from the group consisting of erythritol, xylitol, sorbitol, glucose and sucrose. Sucrose is especially preferred. The preferred polyol starting material having at least four hydroxyl groups must be esterified in at least 60% of the hydroxyl groups with a fatty acid containing from 8 to 22 carbon atoms, preferably from 8 to 18 carbon atoms. . Examples of such fatty acids include caprylic, capric, lauric, myristic, myristoleic, palmitic, palmitoleic, stearic, oleic, ricinoleic, linoleic, linolenic, eleostearic, arachidic, arachidonic, behenic and erucic acids. Fatty acids can be obtained from fatty acids that occur in nature or from synthetic fatty acids; these can be saturated or unsaturated, including positional and geometric isomers. However, to properly provide liquid polyesters of the type used herein, at least about half the fatty acid incorporated in the polyester molecule must be unsaturated. Oleic and linoleic acids and mixtures thereof are especially preferred. The liquid polyol fatty acid polyesters useful in this invention must contain one or more fatty acid ester groups. It is not necessary that all of the hydroxyl groups of the polyol be esterified with fatty acids, but it is preferable that at least 60% of the hydroxyl groups are esterified with fatty acid ester groups. Preferably, substantially all of the hydroxyl groups of the polyol are esterified with fatty acids, ie the polyol portion is completely esterified. The fatty acids esterified to the polyol molecule can be the same or mixed, but as indicated above, a substantial amount of the unsaturated acid ester groups must be present to provide liquid character. To illustrate the above points, a fatty acid di-ester of sucrose would be suitable for use herein, but is not preferred because it has more than two non-esterified hydroxyl groups. Similarly, a sucrose fatty acid tetra ester would be appropriate, but it is not preferred because it also has more than two non-esterified hydroxyl groups. Highly preferred compounds in which all hydroxyl groups are esterified with fatty acids include liquid sucrose-substituted octa-ester fatty acids. The following are non-limiting examples of polyol fatty acid polyesters containing one or more fatty acid ester groups suitable for use in the present invention: glucose oleate, glucose ester of the fatty acids (unsaturated) of soybean oil, fatty acid ester of mixed soybean oil, galactose ester of oleic acid, arabinose ester of linoleic acid, xylose linoleate, sorbitol oleate, sucrose oleate, glucose dioleate, glucose diesters of fatty acids (unsaturated) of soybean oil, digesters of the fatty acids of the mixed soybean oil, galactose diesters of oleic acid, arabinose diesters of linoleic acid, xylose dilinoleate, sorbitol dioleate, sucrose dioleate, glucose trioleate , glucose triesters of the fatty acids (unsaturated) of the soybean oil, triesters of the fatty acids of the soybean oil mixed, galactose triesters of oleic acid, arabinose triesters of linoleic acid, xylose trilinoleate, sorbitol trioleate, sucrose trioleate, glucose tetraesters of the fatty acids (unsaturated) of soybean oil, sugar cane tetraesters Fatty acids of mixed soybean oil, galactose tetraesters of oleic acid, tetraesters of arabinose of linoleic acid, tetralinoleate of xylose, tetraoleate of sorbitol, pentaoleate of galactose, hexaesters of sorbitol of unsaturated fatty acids of soybean oil, xylitol pentaoleate, sucrose tetraoleate, sucrose pentaoleate, sucrose hexaoleate, sucrose heptaoleate, sucrose octaoleate and mixtures thereof. Preferred are polyol liquid esters which are selected from the group consisting of sucrose pentaoleate, sucrose hexaoleate, sucrose heptaoleate, sucrose octaoleate and mixtures thereof. Most preferred are sucrose hexaoleate, sucrose heptaoleate, sucrose octaoleate and mixtures thereof. Preferred polyol fatty acid polyester polyols of the present invention have melting points between -30 ° C and 30 ° C, preferably from -30 ° C to about 27.5 ° C and more preferred from -30 ° C to 25 ° C . The melting points are measured using conventional techniques. The polyol fatty acid polyesters suitable for use herein can be prepared by a variety of methods well known to those skilled in the art. These methods include: transesterification of the polyol with methyl esters, ethyl or glycerol fatty acids used a variety of catalysts; acylation of the polyol with a fatty acid chloride; acylation of the polyol with a fatty acid anhydride; and acylating the polyol with a fatty acid per se.

Thickeners based on carboxylic acid copolymer Another useful component in the compositions of the present invention is a thickener based on carboxylic acid copolymer. These cross-linked polymers contain one or more monomers that are obtained from acrylic acid, substituted acrylic acids and salts and esters of these acrylic acids and substituted acrylic acids, wherein the cross-linking agent contains 2 or more carbon-carbon double bonds and is obtained from a polyhydric alcohol. The preferred polymers to be used herein are of two general types. The first type of polymer is a crosslinked homopolymer of an acrylic acid monomer or derivative thereof (for example, wherein the acrylic acid has substituents at the carbon 2 and 3 positions which are independently selected from the group consisting of C1 alkyl. -4, -CN -COOH, and mixtures thereof). The second type of the polymer is a crosslinked copolymer having a first monomer that is selected from the group consisting of acrylic acid monomer or derivative thereof (as just described in the previous sentence), an acrylate ester monomer of short chain alcohol (i.e. a C-) alcohol OR derivative thereof (e.g., wherein the acrylic acid portion of the ester has substituents at the carbon 2 and 3 positions independently selected from the group consisting of C-alkyl -4, -CN, -COOH, and mixtures thereof), and mixtures thereof; and a second monomer which is a long-chain alcohol acrylate ester monomer (ie Cs-4o) or derivative thereof (eg, wherein the acrylic acid portion of the ester has substituents at the carbon 2 and 3 independently selected from the group consisting of C? -4 alkyl, -CN, -COOH, and mixtures thereof). The combinations of these two types of polymers are also useful in the present invention. In the first type of crosslinked homopolymers the monomers are preferably selected from the group consisting of acrylic acid, methacrylic acid, ethacrylic acid and mixtures thereof, with acrylic acid being most preferred. In the second type of crosslinked copolymers the acrylic acid monomer or derivative thereof is preferably selected from the group consisting of acrylic acid, methacrylic acid, ethacrylic acid and mixtures thereof, with acrylic acid, methacrylic acid being most preferred. and mixtures thereof. The short chain alcohol acrylate ester monomer or derivative thereof is preferably selected from the group consisting of C? -4 alcohol acrylate esters, C? -4 alcohol alcohol methacrylate esters, ethacrylate esters of C? -4 alcohol alcohol, C.sub.4 alcohol and mixtures thereof, the most preferred being alcohol C-4 alcohol acrylate esters, C- alcohol methacrylate esters and mixtures thereof. The long chain alcohol acrylate ester monomer is selected from the group consisting of Cß-40 alkyl acrylate esters, with C este-3o alkyl acrylate esters being the most preferred * The crosslinking agent in both types of these polymers is a polyalkenyl polyester of a polyhydric alcohol containing more than one alkenyl ether group per molecule, wherein the parent polyhydric alcohol contains at least 3 carbon atoms and at least 3 hydroxyl groups. Preferred crosslinkers are those that are selected from the group consisting of allylethers of sucrose and allyletters of pentaerythritol, and mixtures thereof.
