SUBSTANCE: composition of soft toilet soap contains 20-60 mass % of one or more synthetic surfactants, 10-50 % of moistening agent and peeling particles, wherein at least 20 % of particles have major axis length from 100 to 600 mum. EFFECT: soap with improved peeling and moistening properties. 17 cl, 9 tbl
The present invention relates to soap, suitable for local use for cleansing the body, such as skin and hair. In particular, it relates to compositions of soap that is mild to the skin and exfoliates the skin. Exfoliating toilet Soaps are well known. However, most of them are very irritating to the skin due to the fact that they are based on soap, have a high content of hard or inefficient otshelushivanie, low levels of moisturizers or some combination of the aforementioned. Some of the soap prior with a high content of soft synthetic detergents surface-active substances ("Sindet") and high levels of moisturizers were described as not necessarily contain exfoliating particles or beads, such as beads of polyoxyethylene (polyethylene), walnut shells, apricot pits, and the like. See, for example, U.S. patent No. 6376441, U.S. patent No. 6342470, U.S. patent No. 6384000 and U.S. patent No. 6074998.

Not wishing to be bound by the following theories skin care, applicants believe that exfoliation improves skin cleansing, helping to mechanically remove skin dirt and grease. It is also believed that exfoliation helps the process of desquamation. Desquamation is a natural process in which the corneocytes removed from the stratum corneum, which is the top layer of skin cells. The corneocytes are just cells that contain the stratum corneum, and they continuously removed as the skin regenerates. Exfoliation helps to remove scaly of corneocytes, which are ready to be chipped off from the stratum corneum and thereby contribute to obtain a smoother, less flaky skin. Other possible health benefits from exfoliation, in addition to improved removal of particles (flakes) and fat removal, as mentioned above, consist in reducing the number of bacteria on the skin and improving skin blood flow thanks fur the systematic stimulation.

Soap according to the invention contains exfoliating particles, which help to remove dry skin. Without being bound by theory, believe that the degree of exfoliation depends on the size and morphology of the particles and their hardness. Large, rough and solid particles are usually very rude and annoying. Very the scarlet particles, which is very soft, can not serve as an effective otshelushivatsya. Hardness is usually measured on the Mohs scale. The scale of hardness according to the Mohs scale is a method used to measure the ability of one substance to scratch more. The scale comprises, in ascending order of relative hardness, from 1 (mild) to 10 (hardest).
Normal otslushival used in this area include natural minerals such as silica, talc, calcite, pumice, tricalcium phosphate; seeds, such as rice, grain, apricot pits, etc.; crushed shell, such as shell almonds and walnuts; oat flour; polymers, such as beads of polyethylene and polypropylene, flower petals and leaves; balls microcrystalline wax; balls of ester str and the like. These otslushival are used in a wide range of sizes and morphology of the particles covering from micron sizes up to several millimeters.
They also have a range of hardness. Some examples are given in table. 5, below.

The mixture is then left to cure in ambient conditions or accelerated cooling (such as freezing and the like).
For harakterizovali Soaps according to the invention and comparison with comparative free Soaps may be applied one or more of the following tests.
a)Test for exfoliation:
Suitable dye, coloring the stratum corneum (e.g., gentian violet), put spots with a diameter of 2-5 cm on the skin (hand/foot or any other part of your body at will) and leave for 5 minutes to obtain a uniformly colored surface skin cells (corneocytes). Then the excess ink wash, rinsing the stain running water at 35°C for 30 seconds, the skin do not RUB.
Then painted designated wash the tested product. For soap adopted with EBUSY way of washing. Spot on skin moisturize, slightly moisten the soap, RUB the soap directly on the stain for 30 seconds (movement forward and backward), rinse within 15-30 seconds under running water at 35°C, the skin is not rubbed and dried careful strokes. Dried for 10 minutes. Strip cleaning from dry flakes (Cuderm® production CuDerm Corporation, Dallas, Texas), is superimposed on the washed spot at uniform pressure for 30 seconds and then removed. The cleaning strip is photographed by the digital camera Kodak DCS 420 lens 105 mm
Snapshot analyzed using the software image analysis Optimas for covered square/full intensity of stained cells (Optimas® comes Media Cybernetics, Silver Springs, MD). Comparing these data with similar information for lepromatosa plot as follows to estimate the number of exfoliation caused by the tested product:
Exfoliation = (size of the stripes painted on naramata plot - area stripes painted on the washed area)/(area of the stripes painted on naramata plot)
Alternative exfoliation can also be evaluated in the test on the consumers as follows.
The test Protocol consists of:
1) selection of approximately 10-20 women in the age group 25-65 of those who used soap DL is improving the condition of skin;
2) the application under test and the comparative products, each in a week; half of the test participants must first apply the test product and the other half must first apply comparative product;
3) at the end of the trial, the participants give their preferences (on a scale from 0 to 5 points) for the property "exfoliation".
The degree of exfoliation is determined by estimations of consumers, on a scale from 0 to 5 points
b)Test for softness:
i)Test the controlled deposition on the forearm (FCAT), clinical methodology test
This controlled test washing similar to the test described Ertel et al. ("A forearm controlled application technique for estimating the relative mildness of personal cleansing products", J. Soc. Cosmet. Chem., 46, 67 (1995)).
Participants report on testing tools applied in the study phase of conditioning, which consists of the application is assigned, commercially available personal wash cleanser for General home use, for a period of up to four days prior to the beginning of the phase of application of the product. In the first day phase deposition product is visual assessment to determine the quality of the subject. Subjects must have indicators of dryness >1.0 and indicators redness >0.5 and not have cuts and abrasions on the test site or nearby, to be included in F. the memory material. Those eligible to participate in the phase of application of the product, and then are instructed, in accordance with which they cease to use the air conditioning and any other means to care for the skin on the inner part of the forearm, with the exception of the tested preparations for cleaning the skin, which are applied during the washing session.
Eligible subjects thus have four (round) of the assessment area with a diameter of 3.0 cm marked on each forearm with safety for skin handles (8 plots). Visual assessment of redness and dryness is carried out directly before the first wash in each session and again in the afternoon on the last day (day 5).
The procedure of cleaning products in the form of soap
1. Both hands are washed at the same time. Test plots treated sequentially, starting from the place nearest to the area of the bend, and ending at the place nearest to the wrist.
2. The areas closest to the bend on the inner part of the forearm with both right and left hands moistened with warm water (90-100°F/32-38°C).
3. Moist soft jaws Masslinn study participants RUB in a circular motion on wet soap around 6 seconds, which will lead to the release of 0.2 g to 0.5 g of the product.
4. Plot wash assigned product within 10 seconds, followed by 90 seconds the second phase retention foam.
5. Then the above procedure (1-4) repeat for each of the test plot. Then the sections are washed (e.g., at a temperature of 35° (C) within fifteen seconds and dried Pat.
6. Upon completion of the entire procedure is repeated as a whole (two wash/session).
For liquid products: the analyst should prepare liquid products just before washing session, dealing from 0.1 g to 0.5 g of the product either directly on the skin or on a moistened sponge Masslinn, or an alternative material for the application. Then use the washing procedure described above.
Evaluation methods
Basic visual assessment made prior to the beginning of the phase of application and after application, immediately before each session of washing, to assess the dryness and redness. The final visual assessment is carried out after noon on the last day.

Reading from devices produced in the first (baseline) and the last day of the study.
The softness of the test is the product is calculated as 1/(average change of dryness towards the end of the study).
In addition to the visual assessment will be conducted instrumental assessment of the treated areas using evaporimetry and measuring the conductivity of the skin, as described in the above link.
ii) Testing spots
48-hour continuous or 14-day cumulative test on the affected spots: In the 48-hour test spots 5-15%solution/slurry of the product is applied to the shoulder/back of the subject using a standard cotton swab. The reaction to a stimulus is recorded for up to 24 hours after removal of stains. In 14-day cumulative test 5-15%solution/slurry of the product is applied repeatedly every 24 hours for 14 days. The irritation is written not later than 24 hours after the removal of a stain.
The softness of the product being tested is estimated as 1/(average redness 24 hours after the last spot removal).
c.Test for moisture:
Each of the external lower part of the legs involved in the test subject is divided into three sections 2.5 2.5 square inch (6,4 6,4 cm) - upper, middle and lower - a total of 6 test sites on the subject. One or two of the sites remain undeveloped and will be included in the randomization products. The technician should handle areas once or twice the intended amount of test substance in 10 seconds. Cleansing products should estates is on the test plots within a maximum of 90 seconds. The parts should be rinsed for 30 seconds each (for example, using a temperature of 35° (C) ensuring that the test substance from one area does not contaminate another area. After rinsing the test plots gently wipe with a paper towel. The application consists of applying up to 5 different test substances at a designated place, one substance at one test site and one or two of the unprocessed area. Staff research performs the following procedure wash:

Basic visual assessment made prior to the beginning phase of product application and after application, immediately before each of instrumental evaluations to assess the dryness and redness. One trained expert makes all the visual evaluation during the phase of application of the product. The expert examines both the lower part of the leg with the aid of a magnifying lamp with illumination lens 3 diopter and shadowless source fluorescent lighting with circular cooling.
Instrumental assessment
All instrumental evaluations are conducted after a 30-min acclimatization period. Data on humidity and temperature are recorded and will include the ENES in the final report. Instrumental measurements can be made in some or all of the following points in time: 0, 1, 2, 4, 6, 8 and 24 hours after applying product. Tools that should be used with this Protocol include evaporimeter ServoMed with sensors EP1 or EP2, corneometer CM820, hygrometer Skicon Skin with sensor MT-8C and hygrometer. The room temperature is kept between 68°F to 77°F (20°C to 25°C)and relative humidity from 30% to 40%.
Hydration is defined as the average change from baseline (visible dryness or skin hydration).
d)Test subsidence humidifier:
Pre-condition the skin of the subject (hands/feet) not containing humidifier product up to 2 days prior to testing. To assess the level of the humidifier (e.g., fatty acids)present on the skin before applying the product, is the basic extraction. Carry out controlled single application of the product on the skin (hands or feet). For washing RUB soap on the skin for 30 seconds, the foam is left for 90 seconds, rinse for 30 seconds (for example, using a temperature of 35°C), then gently Pat dried. After this section is extracted using a suitable solvent (isopropyl alcohol/methanol 1:1). Extraction is as follows: on the skin put the glass bowl (diameter 3 cm). In whom it is placed 3 ml of solvent and gently stirred with a glass rod for 2 minutes. The solvent is removed by pipette. This stage is repeated with 3 ml of fresh solvent to collect a total of 6 ml of the extract. The extracts will be analyzed by the content of stearic acid/palmitic acid, using either LC/MS or GC/MS, or the like.
e)Check for abrasion of the skin:
Abrasion of the skin is determined by the estimated consumer reactions to abrasion on a scale from 0 to 9 points (0 means no erase, 9 means the abrasion caused by the roller (i.e. a washcloth for the soul, consisting of thin plastic fibers, see also, for example, U.S. patent No. 5650384, in the name of Gordon et al.).
This test is carried out with 50 untrained consumers. They are asked to evaluate the abrasion test product on a scale from 0 to 9 points. Data normalized to response on the soap without otshelushivatsya, which is assigned zero points, and to the roller, which is assigned 9 points. The test products are applied in place of the bend of the forearm by wetting the soap and friction movements forward and back 10-15 times.
f)Test the cleaning efficiency
Model pollution (sebum/makeup - for example, lipstick or mascara) is applied to a specific location on the forearm/person. Plot wash product. For washing RUB soap on the skin for 1 minute, rinse for 30 seconds (for example, at a temperature of 35°C) and dried with a light Pat on the Number of remote dirt/makeup is estimated from the difference in the readings of the device for measuring the intensity of the color, using, for example, Minolta Chromameter®, model CM 2002, taken before and after washing. Alternatively, collect digital images with high magnification and analyzed using the software Optimas® to determine the amount of dirt/makeup removed when washing.
Applying cosmetics
Cosmetics applied to the marked section 3.5 2.5 cm on the inner side of the forearm manner consistent with its normal use. Cosmetic products should be applied in a standardized way to ensure that the loss is approximately equal to the weight of the cosmetics and the floor of the test section is homogeneous. Standards for the application of cosmetics are as follows:

Application of pollution
Pollution is put on the marked areas of size 3.5 x 2.5 cm on the inner side of the forearm in the manner described below, which are specific to each individual research if the use of pollution. Application technique pollution tacos is:
1) fat - causing 0.25 g 1.5 g;
2) food - put 0.25 g 1.5 g;
3) protein - causing 0.25 g 1.5 g;
Product testing
A baseline measurement is done using a device for measuring the color intensity of Minoltra Chromameter CM-2002. Then apply makeup or contamination on the identified test sites, as described above.
Measurement using the device are removed again after the cosmetics will dry out for 10 minutes, then makeup/dirt is removed. The standard washing procedure used to remove makeup/dirt, is a 30-second wash with 0.5 ml of liquid product with a 15-second rinsing under running water at a suitable constant temperature (for example, 35°C). When the product is used in the form of impregnated wipes, cloth rubbed in a circular motion for 15 seconds. The last measurement device is removed after makeup/dirt will be removed. This procedure can be carried out twice a day for up to three days. In studies with repeated application, conduct a visual assessment of dryness and redness using standard visual measurement scale, as described above.
g)The smoothness of the skin
The smoothness of the skin is evaluated (clinically) by means of the device Primes® (in vivo optical device that measures the topography of the skin supplied GFM Esstezhnik GmbH, Berlin, Germany is). Measured base roughness (leg/hands - initial dryness degree approximately 1-2). For washing RUB soap on the skin for 30 seconds and the foam leave for 90 seconds, rinse for 30 seconds at 35°C. Again measure the roughness after 30 minutes after the procedure, wash. This procedure can be carried out twice a day up to 5 days.
Smoothness is defined as the average decrease in roughness at the end of the study period. Alternative smoothness of the skin can also be evaluated in the test for the consumers as follows:
The test Protocol for the consumers consists of:
1) selection of approximately 10-20 women in the age group 25-65 from those who use the means to care for a person in the form of soap;
2) the application under test and the comparative products in the course of a week each; half of the participants should apply to first test the product, and the other half must first apply comparative product;
3) at the end of the test, the participants give their preferences (on a scale from 0 to 5 points) on the property, the Skin feels smoother".
Smoothness is defined as consumers ' rating on a scale from 0 to 5 points.
h) Magosti skin
The softness of the skin can be estimated using linear rheometer for skin (Goodyear Scientific Instruments, UK). Exfoliated skin contains less dry scales, therefore, it is softer/less is hard. The test includes basic readings rheometer for skin (foot/hand) to measure the dynamic stiffness constants of the springs (mg/mm) for skin that is associated with the hardness/softness of the skin. For washing RUB soap on the skin for 30 seconds, then lather leave on for 90 seconds, rinse 30 seconds (at a suitable temperature, for example, 35°C) and the skin dry with a light Pat. Following the measurement of the hardness/softness of the skin and hold for 30 minutes after washing. This procedure can be carried out twice a day for up to 5 days. Softness is defined as the average decrease in dynamic stiffness constants of the springs over the study period observed during the study.
Alternative softness of the skin can also be evaluated in the test for the consumers as follows.
The test Protocol consists of:
1) selection of approximately 10-20 women in the age group 25-65 from those who use the means to care for a person in the form of soap;
2) the application under test and the comparative products in the course of a week each; half of the participants should apply to first test the product, and the other half must first apply comparative product;
3) at the end of the test, the participants give their preferences (on a scale from 0 to 5 points) on the property Leather is more delicate.
Softness is determined by assessing consumers HQ the Les from 0 to 5 points
i)Test method pH
To form an aqueous suspension by mixing 10 grams of the formula soap with 90 g of water for the formation of a 10 %suspension. Then measured the pH of the suspension at 25°C.
j)Test method for Zein
Cleansing base toilet soap according to the invention has a solubility of Zein below about 50, 40, 30, and most preferably up to about 25, according to the method of determining the solubility of Zein set forth below. The lower the level of Zein, the product is considered to be softer. This method enables measurement of the solubility of Zein (corn protein grains) in solutions cleansing bases, as follows.
0.3 g of cleansing basics and 29.7 g of water are thoroughly mixed. To this add 1.5 g of Zein and stirred for 1 hour. The mixture is then centrifuged for 30 minutes at a speed of 3000 rpm After centrifugation the pellet is extracted, washed with water and dried in a vacuum oven for 24 hours until almost all the water evaporate. Measure the weight of the dried granules and calculate the percentage solubilizing Zein by the following equation:
% solubilizing Zein = 100 (1-weight of dried granules/1,5).
In addition, % Zein described in the following reference: E. Gotte, "Skin compatibility of tensides measured by their capacity for dissolving zein protein", Proc. IV International Congress of Surface Active Substances, Brussels, 1964, pp 83-90.
k)Organoleptic index exfoliate soap
The body is elepticheskih index exfoliate soap is determined by the following procedure. The consumer takes the soap in one hand and rotates it under running water at 35°C. records the number of rotations required to otshelushivaet to be perceived (i.e. tactile sensations) to the consumer. Index exfoliate soap is defined as the average number of spins required to feel the exfoliating particles in the soap.
