Description

CLEANING COMPOSITIONS TECHNICAL FIELD The present invention relates to cleaning compositions.

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

BACKGROUND OF THE INVENTION The mild cosmetic compositions must satisfy 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 up of several layers of cells that line 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 called the cuticle. Anionic surfactants can penetrate the stratum corneum membrane and the cuticle and, through delipidization, destroy the integrity of the membrane and lose barrier and water retention functions. 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 most sparkling 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.

Thus, there is a need for personal cleansing compositions that provide an improved rinsing sensation, while at the same time having excellent skin softness, in addition to excellent product characteristics, 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 having a "non-slip" rinsing sensation while having excellent softness characteristics are provided by a combination of certain water-insoluble oils, such as certain polyalphaolefin oils or oils. silicone hydrophobically modified, in combination with a water-soluble surfactant system. Although not wishing to be bound by theory, the "non-slip" rinsing sensation is considered to be associated with an increase in wet skin friction. An important mechanism for the action of said oils is considered as the ability of these to deposit and change the surface energies of the skin, that is, to make the surface of the skin more hydrophobic. During rinsing, the water film is considered to be the lubricant for the skin, and as the hydrophobicity of the surface increases the water film is also destabilized and the surface dehumidifies. 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".

BRIEF DESCRIPTION OF THE INVENTION According to the present invention, a rinsable liquid personal cleansing composition comprising water, surfactant and 0.5% or more of an oil not soluble in water is provided wherein the oil not soluble in water provides an Average Friction Change Value for the composition of 2 or larger as measured by the Friction Measurement Technical Test Method. The compositions of the present invention provide an improvement in the rinsing sensation while at the same time being exceptionally gentle for the skin. All concentrations and ratios herein are by weight of the cleaning composition, unless otherwise specified. The surfactant chain lengths are also based on the average weight chain length, unless otherwise specified.

It is preferred for the compositions herein to provide not only a "non-slip" rinsing sensation but also a "non-sticky" or "non-sticky" feeling on the skin at the time of rinsing. Therefore, it is preferred to use water insoluble oils that can be described as "non-sticky". The degree of tackiness for water insoluble oils can be measured by the technical tack method detailed below. In preferred embodiments, the water-insoluble oil used herein has a tack index of 120% for Viscasil 5M (Dimethicone) or less as measured by the tackiness test method described hereinafter. Most preferred are those with a tack index of 110% for Viscasil 5M (Dimethicone) or less. Especially preferred are those with a 100% tack index for Viscasil 5M (Dimethicone) or less, especially 1% a 100% Technical sticking test method The sticky technical test method described herein was developed using the basic tack theory. The basic theory of tackiness was summarized in the Stefan equation that describes the viscous separation resistance for two disks connected by a thin liquid "pressure film". This is also used in other areas of technology where the evaluation of tackiness is critical, for example, printing ink. The reference to the basic tack theory can be found in the article by Phillips, J.C. and Chaing, A. C, "Low Speed Tack Measurements of Fluids and Inks," J. Applied Polymer Science, 1995, 58, 881-895. A simplified form of the Stefan equation is shown below for the maximum force, F, applied for time, t, to separate the disks that have a radius r connected by a liquid film that has a thickness h and viscosity?: F ^ 3.p.?r4 (1) d.t.h2 From this equation, and when the surfaces are separated to a speed v, the force of separation becomes: F = k.? v (2) where k is a constant if h and r are fixed in a series of comparative experiments. The above is the basis for determining the relative tackiness of oils. The instrument used is an Instron 4301 voltage tester, coupled with a 10N load cell and 10 mm diameter of a soft steel plate in the movement crosshead. The fixed lower plate is also made of mild steel and has a flexible rubber spring (56 N / mm) and leveling device coupled with the base of the instrument. The same plates and spring assembly are used to establish the comparison measurements. The plates are approximated and placed in parallel using the leveling device. The contact force is calculated for each oil to give a consistent film thickness of the equation: F = 0.0726. ? (3), where? is the viscosity of the oil in Pa.s, F is the contact force in N. The machine is prepared to stop a compression force of F. Approximately three drops of oil are placed on the bottom plate, directly below the plate higher. The plates come together, maintaining the required force for one minute. The tension speed is set at 1 mm / min and the maximum force is recorded as the stickiness observation. The plates were joined again and a total of three observations were collected. As a verification for the most remote observations, the scale / average for the three observations must be less than 10%. If the above does not happen, three other observations are collected. Three reference oils are included in each series of comparisons, and these are Indopol H100, Viscasil 5M (Dimethicone) and SF1000. The three oils cover a stickiness scale and their data are used to determine the relative tackiness of the other oils and to evaluate the method of reproducibility. In each experiment, the maximum force ratio for an oil is expressed as a percentage of the value for Viscasil 5M (Dimethicone), and this is the stickiness index. When the above is correctly established, a coefficient of variation of less than 15% is expected in said data. The significant differences of a series of oils are determined using an ANOVA form of logarithm of transformed force data.

Optional Ingredients The compositions herein may additionally comprise a wide variety of optional ingredients. Non-limiting examples of such ingredients are described below. Another water-insoluble ingredient for skin / hair care suitable for use in the present foaming compositions 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. Said polyol esters are derived from a radical or portion of polyol and one or more radicals or portions of carboxylic acid. 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. Said 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. 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 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, are also 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 such fatty acids include caprylic, capric, lauric, myristic, myristoleic, palmitic, palmitoleic, stearic, oleic, ricinoleic, linoleic, linolenic, eleostearic, archidic, 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 preferred 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 preferred. 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 preferable that the polyester contains no more than two unesterified hydroxyl groups. More preferably, 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 present to provide liquidity. 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 tetra fatty acid ester may be suitable, but is not preferred because it has more than two unesterified hydroxyl groups. A sucrose fatty acid ester of sucrose may be preferred because it has no more than two unesterified hydroxyl groups. Highly preferred 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 present invention: glucose tetraoleate, glucose tetraesters of fatty acids of soybean oil ( unsaturated), the mixed sugar soya 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 acids fatty acids of unsaturated soybean oil, xylitol pentaoleate, sucrose tetraoleate, sucrose pentaolate, sucrose hexaoleate, sucrose heptaoleate, sucrose ochalate, and mixtures thereof. As noted above, highly preferred polyol fatty acid esters are those wherein the fatty acids contain from about 14 to about 18 carbon atoms. Preferred liquid polyol polyesters for use herein have full melting points below about 30 ° C, preferably below about 27.5 ° C, more preferably 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 prepared 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.
