Description

CLEANING COMPOSITIONS TECHNICAL FIELD The present invention relates to cleaning compositions. In particular the invention relates to mild personal cleansing compositions that exhibit improved rinsing sensation in combination with good skin feel attributes, and foaming properties that are suitable for simultaneously cleaning and conditioning the skin and / or hair and that can be used, for example in the form of foam bath preparations, shower bath products, skin cleansers, hand, face and body cleansers, shampoos, etc.

BACKGROUND OF THE INVENTION 15 Soft cosmetic compositions must meet a number of criteria including cleaning energy, foaming properties and softness / low irritability / good feeling with respect to the skin, hair and ocular mucosa. The skin is made of several layers of cells 20 that coat and protect the underlying tissue. The fibrous proteins of keratin and collagen form the skeleton of its structure. The outermost layer is referred to as the stratum corneum. Similarly, the hair has an outer protective coating that covers the fiber of the hair that is called ^ í = riíii Htftti .... ~ * fa¡tfr III iíÉif- j | jjjj ^ g | jj ^ "to cuticle. Anionic surfactants can penetrate the stratum corneum membrane and the cuticle and, by delipidization destroy membrane integrity and barrier functions and lose water retention. Such interference with the protective membranes of the skin and hair can lead to a rough sensation of the skin and irritation of the eyes and can eventually allow the surfactant to trigger the irritation that creates an immune response. The ideal cosmetic cleansers should gently cleanse the skin or hair without interrupting the structural lipids and / or drying the hair and skin and without irritating the ocular mucosa or making the skin dense after frequent use. The more foaming soaps, shower bath products, shampoos and bars fail in this regard. Certain synthetic surfactants are known to be mild. However, a major drawback of some mild synthetic surfactant systems when formulating for shampooing or personal cleansing is that they have what could be described as a "slippery" or "slippery" rinse sensation that is not pleasant to some consumers. The use of certain surfactants such as potassium laurate, on the other hand, can yield an acceptable rinsing operation but at the expense of the clinical smoothness of the skin. These two facts make the selection of suitable surfactants in the formulation process of rinsing sensation and benefit of softness an act of delicate balance.

In this way, there is a need for personal cleansing compositions that provide a "non-slip" rinsing sensation, while at the same time having excellent skin softness, in addition to excellent features. of the product, such as foam, cleaning, stability, thickening, rheology and sensory attributes of the skin in use. Certain polyalphaolefin oils are known for their use in personal cleansing compositions for the skin and hair. References for the use of such oils in personal cleansing formulations are found in WO 97/09031, E.U.A.-A-5441730, WO 94/27574, EP-A-0692244, WO 96/32092 and WO96 / 06596. Hydrophobically modified silicone oils are also known for their use in personal cleansing compositions and are described for example in JP 05-310540. Surprisingly, it has been found that personal cleansing compositions have a "non-slip" rinsing sensation that at the same time excellent softness characteristics are provided by a combination of certain water-soluble oils, such as certain polyalphaolefin oils or hydrophobically modified silicone oils, in combination with a water-soluble surfactant system. While not wishing to be bound by theory, the feeling of "non-slip" rinse is considered associated with an increase in wet skin friction. An important mechanism for the action of these oils is considered as the capacity of these to deposit and change the - ~. South ", & - *** .... > * ^. "^^. . . * m * mmm ~~, ^ ¿ai ^. ^^,, ^, ^ .. surface energies of the skin, that is, making the surface of the skin more hydrophobic. During the rinsing, the water film is considered to be the lubricant for the skin, since the hydrophobic character of the surface is increased so that the water film is destabilized and the surface is dehumidified. As a result, the water film first becomes thin and then moves, allowing some direct contact between the surfaces. Both changes increase friction and produce "non-slip rinsing".

Another water insoluble skin / hair care ingredient 20 suitable for use in the foaming compositions herein is a liquid polyol carboxylic acid ester. The preferred polyol ester for use herein is a non-occlusive liquid or liquefiable polyol carboxylic acid ester. Sayings .i;. "^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The polyol esters are derived from a disulfide or polyol portion and one or more radicals or carboxylic acid moieties In other words, said esters contain a portion derived from a polyol and one or more portions derived from a carboxylic acid. Said carboxylic acid esters can also be derived from a carboxylic acid, these carboxylic acid esters can also be described as liquid polyol fatty acid esters, because the terms carboxylic acid and fatty acid are often used interchangeably by those skilled in the art. The preferred liquid polyol polyesters employed in this invention comprise certain polyols, especially sugars or sugar alcohols, esterified with at least four fatty acid groups.As a consequence, the polyol starting material must have at least 4 hydroxyl groups. Examples of preferred polyols are sugars, including monosaccharides and disaccharides, and sugar alcohols. Examples of monosaccharides containing four hydroxyl groups are silose and arabinose and sugar alcohol derived from silose, which has five hydroxyl groups, for example, xylitol. The monosaccharide, erythrose, is not suitable in the practice of this invention since it only contains three hydroxyl groups, but the sugar alcohol derived from erythrose, for example, erythritol, contains four hydroxyl groups and can be used accordingly. The five suitable hydroxyl groups containing monosaccharides are galactose, fructose and sorbose. Sugar alcohols containing six -OH groups derived from the products of hydrolysis of sucrose, as well as glucose and sorbose, for example, sorbitol, also; ÍQtr suitable. Examples of disaccharide polyols that can be used include maltose, lactose and sucrose, which contain eight hydroxyl groups. The preferred polyols for preparing the polyesters for use in the present invention are selected from the group consisting of erythritol, xylitol, sorbitol, glucose and sucrose. Sucrose is especially preferred. The polyol starting material having at least four hydroxyl groups is esterified in at least four of the -OH groups with a fatty acid containing from about 8 to about 22 carbon atoms. Examples of said fatty acids include caprylic acid, capric, lauric, myristic, myristoleic, palmitic, palmitoleic, stearic, oleic, ricinoleic, linoleic, linolenic, eleostearic, arquid, arachidonic, behenic, and erucic. Fatty acids can be derived from fatty acids that occur naturally or synthetically. These can be saturated or unsaturated, including positional and geometric isomers. However, in order to provide erred liquid polyesters for use herein, at least about 50% by weight of the fatty acid incorporated in the polyester molecule must be unsaturated. Oleic and linoleic acids and mixtures thereof are especially erred. The polyol fatty acid polyesters useful in this invention should contain at least four fatty acid ester groups. It is not necessary that all of the hydroxyl groups of the polyol be esterified with fatty acid, but it is erable that the polyester contains no more than two unesterified hydroxyl groups. More erably, substantially all of the hydroxyl groups of the polyol are esterified with fatty acid, ie, the polyol portion is substantially completely esterified. The fatty acids esterified for the polyol molecule can be the same or mixed, but as noted above, a substantial amount of ester and unsaturated acid groups must be ent to provide fluidity. To illustrate the above points, a sucrose acid triester may not be suitable for use herein because it does not contain the four fatty acid ester groups required. A sucrose fatty acid tetra ester of sucrose may be suitable, but is not erred because it has more than two unesterified hydroxyl groups. A sucrose fatty acid ester of sucrose may be erred because it has no more than two unesterified hydroxyl groups. Highly erred compounds in which the hydroxyl groups are esterified with fatty acids include the liquid sucrose octa-substituted fatty acid esters. The following are non-limiting examples of specific polyol fatty acid polyesters containing at least four fatty acid ester groups suitable for use in the ent invention: glucose tetraoleate, glucose tetraesters of soybean oil fatty acids (unsaturated ), the mixed sugar soybean oil fatty acid tetraesters, the galactose tetraesters of oleic acid, the arabinose tetraesters of linoleic acid, the xylose tetralinoleate, the galactose pentaolate, the sorbitol tetraoleate, the sorbitol hexaesters of fatty acids of unsaturated soybean oil, xylitol pentaoleate, sucrose tetraoleate, sucrose pentaolate, sucrose hexaoleate, sucrose heptaoleate, sucrose ochalate, and mixtures thereof. As noted above, the highly erred polyol fatty acid esters are those wherein the fatty acids contain from about 14 to about 18 carbon atoms. erred liquid polyol polyesters for use herein have full melting points below about 30 ° C, erably below about 27.5 ° C, more erably below about 25 ° C. The full melting points reported herein are measured by differential scanning calorimetry (DSC). Polyol fatty acid polyesters suitable for use herein can be ared by a variety of methods well known to those skilled in the art. Such methods include: transesterification of the polyol with fatty acid esters of methyl, ethyl or glycerol using a variety of catalysts; acylation of the polyol with a fatty acid chloride; acylation of the polyol with a fatty acid anhydride; and acylation of the polyol with a fatty acid; per se.
