Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

【Technical field】

The present invention relates to cleansing compositions. Particularly with regard to mild body cleansing compositions, they exhibit an improved rinsing feel combined with good skin feel properties and foaming properties suitable for simultaneous washing and conditioning of the skin and / or hair, and also for example foams It can be used for bath preparations, shower supplies, skin cleansers, hand, face and body cleansers, shampoos, etc.

[0002]

BACKGROUND OF THE INVENTION

Mild cosmetic compositions must meet several criteria, including detergency, foaming properties, and mild / hypoallergenic / good feel with respect to skin, hair and eye mucous membranes. The skin is made up of several layers of cells, and the keratin and collagen fibrous proteins that protect the underlying tissue form the skeleton of that structure. The outermost of these layers is called the stratum corneum. Hair also has a protective outer skin surrounding the hair fibers and is called a cuticle. Anionic surfactants can penetrate the keratinous membrane and cuticle and, due to their delipidating action, disrupt the integrity of the membrane, leading to a loss of barrier and water retention capabilities. This interference with skin and hair overcoats can cause skin roughness and eye irritation, and surfactants can sometimes trigger irritation from the immune response.

[0003] The ideal cosmetic cleansing agent gently cleanses the skin and hair, has no disruption of lipid structure and / or dryness of the hair skin, and does not irritate the mucous membranes of the eyes or leave the skin tight after frequent use. There is no one. Most lathering soaps, shower and bath preparations, shampoos and bar soaps are unsatisfactory in this regard. Certain synthetic surfactants are known to be mild. However, the difficulty with some mild surfactants when formulated for shampooing or body cleansing is that the rinse feel is "slippy" or "non-d
raggy) is not preferred by some consumers. On the other hand, the use of certain surfactants, such as potassium laurate, can provide adequate rinse feel performance, but is These two facts make the choice of a suitable surfactant in the formulation process for rinsing feel and gentleness a subtle task, thus lathering, detergency, and stability. In addition to excellent product properties such as consistency, consistency, rheology and feel on the skin, there is a need for a body cleansing composition that provides a "free flowing" rinse feel while having excellent skin soothing properties Exists.

[0004] Certain polyalphaolefin oils are known for use in body cleansing compositions for the skin and hair. References for the use of such oils in personal cleansing agent formulations are given in WO 97/09031, U.S. Pat.
441730, WO94 / 27574, EP-A-5441730, European Patent Application-0692244, WO96 / 32092 and WO96 / 06596. Hydrophobically modified silicone oils are also known for use in personal cleansing compositions and are disclosed, for example, in JP 05-310540.

[0005] Surprisingly, body cleansing compositions that now have excellent mild properties and at the same time have a "free flowing" rinsing feel have been combined with water-soluble surfactant systems to provide certain polyalphaolefin oils or It has been found that it can be obtained in combination with certain water-insoluble oils, such as hydrophobically modified silicone oils. While not intending to be bound by theory, it is believed that the "smooth" rinse feel is associated with wet skin friction. An important mechanism for the action of such oils is thought to be their ability to deposit and change the surface energy of the skin, ie, make the skin surface more hydrophobic. During rinsing, the water film is considered to be a lubricant for the skin, and as the surface becomes more hydrophobic, the water film destabilizes and dehumidifies the surface. As a result, the water film first becomes thinner and then displaces, with some direct contact between the surfaces. Both changes increase friction and create "draggy rinsing".

[0006]

Summary of the Invention

The present invention provides a body rinse cleansing composition comprising water, a surfactant and a water-insoluble oil, wherein the water-insoluble oil has an average rinse of less than or equal to 3.5 as measured by a rinse touch panel test on the composition. It gives a feel value. The compositions of the present invention provide an improved rinsing feel while at the same time being very mild to the skin. The concentrations and ratios herein are by weight of the cleansing composition unless otherwise specified. Surfactant molecular chain lengths are also based on weight average chain length unless otherwise specified.

DETAILED DESCRIPTION OF THE INVENTION

The liquid cleansing composition herein comprises water, a surfactant, and a water-insoluble oil, wherein the water-insoluble oil has an average rinse of less than or equal to 3.5 as measured by the rinse touch panel test described below. It gives a feel value. Preferably, the average rinse feeling value given to the composition by the water-insoluble oil is 3.25 or less, more preferably 3.0 or less. In a preferred embodiment, the water-insoluble oils used herein have an average rinse feel to the composition in the range of 3.5 to 1.0. Of note is that the water-insoluble oil contributes directly to imparting a "smooth" rinse feel to the composition, especially giving the composition an average rinse feel of 3.5 or less. In other words, a composition corresponding to the composition of the present invention, but without the water-insoluble oil as defined herein, will have an average rinse feel value of greater than 3.5. As used herein, "rinse feel" means the skin sensation during the treatment of rinsing foam from the skin after cleansing with the cleansing composition. The type of rinse feel obtained according to the present invention can be described in terms such as "smooth" rinse feel, "soap-like" rinse feel and "smooth" or "non-sticky" rinse feel. Such "smooth", "soap-like", "smooth" or "non-sticky" rinse feeling can be detected by increased friction between hand and skin while rinsing foam from the skin.

[0008] As used herein, the term "water-insoluble" with respect to oils refers to water insoluble in room temperature distilled water without the addition of other auxiliaries and / or components described herein.

It has a tackiness index of 100% or less, especially 1% to 100%.

Tackiness Technical Test Method The tackiness test method described here was developed using the basic theory of tackiness.
The basic theory of sticking is summarized in the Stefan equation which describes the viscous resistance of separation for two disks joined by a thin "pressed film" of liquid. This equation is also used in other technical fields where adhesion evaluation is important, for example in the field of printing inks. Literature on basic adhesion theory can be found in Phillips, JC and Chaing, AC, “Low Speed Tack Measurements of
Fluids and Inks ”, J. Applied Polymer
Science, 1995, 58 , 881-895. In a simplified form of the Stefan equation, the maximum force F applied at time t to pull apart a disk of radius r bound by a liquid film of thickness h and viscosity η is given by:

F = 3. π. η. r ⁴ (1) 8. t. h ^{2 From} this equation, when the surface is pulled apart at velocity v, the separation force is: F = k. η. where k is constant if fixed in a series of comparative experiments. This is the basis for determining the relative tackiness of oils. The equipment used was an Instron 4301 tensile tester with a 10N load cell and a 10 mm diameter smooth steel disc mounted on a movable crosshead. The fixed lower panel is also made of smooth steel and attached to the equipment base with a compliant rubber spring (56 N / mm) and a level. The same disk and spring assembly is used for comparative measurements. The disks are set close to each other and set in parallel using a level. The contact force is calculated by the following equation so as to give a consistent film thickness for each oil.

F = 0.0726η (3) where η is Pa. The oil viscosity represented by s and F is the contact force represented by N (Newton). The meter is set to stop at compression force F. Approximately three drops of oil are placed on the bottom just below the upper disk. Both boards are brought together and held at the required pressure for one minute. 1
Pulling speeds up to mm / min and maximum force are recorded as adhesion measurements. The two panels are recombined and a total of three observations are collected. As a check for missed observations, the range / average for three observations should be less than 10%. If not, collect three more observations. Three reference oils were included in each set comparison,
These are Indopol H100, biscasil 5M (dimethicone) and SF1000. These three oils cover the range of tack and the data is used to determine the relative tack of the other oils and to evaluate the reproducibility of the measurement method. In each experiment, the maximum force ratio for a given oil is expressed as a percentage of the value for Biscasil 5M (Dimethicone), which is the Tackiness Index. If set correctly, a coefficient of variation of less than 15% is expected for these data. Significant differences from a set of oils are determined using one-way ANOVA of log-transformed force data. result

In statistical analysis, each oil differs significantly (95%) in tack.

Optional Ingredients The compositions herein may additionally comprise a wide range of optional ingredients. Non-limiting examples of such components are described below. Another water-insoluble skin / hair care ingredient suitable for use in the foaming compositions herein is a liquid polyol carboxylic acid ester. Preferred polyol esters for use herein are non-storing liquid or liquefiable polyol carboxylic esters. These polyol esters are derived from a polyol group or component and one or more carboxylic acid groups or components. In other words, these esters have components derived from one or more components derived from polyols and carboxylic acids. These carboxylic esters can also be derived from carboxylic acids. These carboxylic esters can also be described as liquid polyol fatty acid esters. This is because carboxylic acids and fatty acids are used interchangeably as terms by those skilled in the art. Preferred liquid polyol polyesters employed in the present invention include certain polyols esterified with at least four fatty acid groups, especially saccharides or sugar alcohols. Therefore, the polyol starting material must have at least four esterifiable hydroxyl groups. Examples of preferred polyols are sugars, including monosaccharides and disaccharides, and sugar alcohols. Examples of monosaccharides having four hydroxyl groups are xylose and arabinose and sugar alcohols derived from xylose having five hydroxyl groups, ie xylitol. The monosaccharide erythrose is unsuitable for the practice of the invention because it contains only three hydroxyl groups, but the sugar alcohol derived from erythrose, erythritol, has four hydroxyl groups and can therefore be used.
Suitable pentahydroxy-containing monosaccharides are galactose, fructose, and sorbose. Also suitable are sucrose and sugar alcohols containing 6-OH groups derived from the hydrolysis products of glucose and sorbose, namely sorbitol. Disaccharide polyols that can be used include maltose, lactose, and sucrose, all containing octahydroxy groups. Preferred polyols for the preparation of the polyesters used in the present invention are selected from erythritol, xylitol, sorbitol, and sucrose. Sucrose is particularly preferred.

[0055] The polyol starting material having at least four hydroxyl groups has at least four of the -OH groups esterified by a fatty acid having from about 8 to about 22 carbon atoms. Examples of such fatty acids are caprylic, capric, lauric, myristic, myristoleic, palmitic, palmitoleic, stearic, oleic, ritinoleic, linoleic, linolenic, oleostearic, arachidic, Including arachidonic acid, behenic acid, and erucic acid. Fatty acids are derived from natural or synthetic fatty acids; they may be saturated or unsaturated, including positional and geometric isomers. However,
To provide a preferred liquid polyester for use herein, at least about 50% by weight of the fatty acids combined into polyester molecules should be unsaturated. Oleic and linolenic acids, and mixtures thereof, are particularly preferred. The polyol fatty acid polyester useful in the present 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 a fatty acid, but it is preferred that the polyester does not have more than one unesterified hydroxyl group. More preferably, substantially all of the hydroxyl groups of the polyol are esterified with fatty acids, ie, the polyol component is substantially completely esterified. The fatty acids esterified to the polyol molecules may be the same or mixed, but, as noted above, a substantial amount of unsaturated acid ester groups must be present to provide a liquid.

To illustrate the above, sucrose triesters would not be suitable for use here because they do not have the required four fatty acid ester groups. Sucrose tetrafatty acid esters may be suitable, but are not preferred because they have two or more unesterified hydroxyl groups. Sucrose hexafatty acid esters may be preferred because they do not have more than one unesterified hydroxyl group. Highly preferred compounds in which the hydroxyl groups are all esterified with fatty acids include liquid sucrose octa-substituted fatty acid esters. The following are non-limiting examples of specific polyol fatty acid polyesters having at least four fatty acid ester groups and suitable for use in the present invention: glucose tetraoleate, glucose soybean fatty acid (unsaturated) tetraester, mannose mixed soybean oil Fatty acid tetraester, galactose oleate tetraester, arabinose linoleate tetraester, xylose tetralinolenate, galactose pentaoleate, sorbitol unsaturated soybean oil fatty acid hexaester, xylitol pentaoleate, sucrose tetraoleate, sucrose Pentaoleate, sucrose hexaoleate, sucrose heptaoleate, sucrose octaoleate, and mixtures thereof.

Production Method The composition can be produced by first preparing a premix (premix) of a surfactant and a suspending agent. This premix should not contain more than 15% surfactant by composition weight. To do this, the surfactant (excluding the sarcosine salt), a portion of the water, the preservative powder and the pH adjuster are combined with slow stirring. The mixture is then heated to about 90 ° C., during which the fatty alcohol / fatty acid, suspending agent and sodium chloride are added with stirring. The mixture is held at the elevated temperature for about 5 minutes to 1 hour and then cooled at a controlled rate from 30 ° C to 40 ° C through a heat exchanger to crystallize the suspending agent. The remaining water is then added to the premix, followed by the water-insoluble oil, the remaining surfactant, the liquid disinfectant and the fragrance. This part of the process is performed at room temperature, with gentle stirring to obtain the preferred droplets of 5 to 20 microns in diameter. The product gives excellent rinsing feel and mild attributes, together with excellent rheological properties during storage, removal and use, good including skin conditioning, skin wetness, good product stability, washing and lathering Are combined.
