Description

SINERGISTIC PROCESS OF PERSONAL HYGIENE DESCRIPTION OF THE INVENTION The present invention relates to a synergistic process of personal hygiene which provides a process comprising combining a novel liquid composition, preferably a cosmetic cleansing composition, with an application vehicle to produce a personal care product. The cosmetic cleaning composition is thickened under dilution, whereby the performance of the personal hygiene product is increased. The invention further relates to such cosmetic cleansing compositions. The viscosity of the novel liquid composition is increased in an aqueous environment and is especially beneficial when used in combination with an application vehicle. It is believed that this increase in viscosity, during use, is responsible for the improved performance of the product. During the last years, the personal hygiene cleaning product market has changed from soap bars to more modern and sophisticated products, mainly liquid soap products. This trend, originally observed in the European, American and Japanese markets, is being followed in other countries and in other continents. The liquid soap products herein have associated disadvantages, such as cost, performance for the consumer after use, or even a recognition by the consumer compared to soap bars. What is meant by yield to T ^^ consumer after use, is the amount of product functionally available and not that which is removed before that the consumer has made use of the product. One of the disadvantages of conventional liquid soaps is the high wear factor caused by the sliding of the liquid soap product between the fingers, or, which is partially washed or rinsed when used. with sponges before the consumer has time to use it. It is believed that this is due to the low viscosity of the product. In this way, a significant part of the product is thrown away before it can perform its function. This "loss" means that larger quantities of the product with a consequent impact on the cost / benefit perceived by the consumer. It also results in a huge harmful influence under the environment, caused by unnecessary effluence and an exaggerated consumption of starting materials.

EP 254 653 (Cotelle S.A. and Henkel) refers to thickener concentrates after dilution and describes compositions which are thickened with an excess of NaCl. WO 93/03129 (Unilever) describes a concentrated liquid for light duty washing, which contains a mixture of anionic and nonionic surfactants; a solvent and an alkanediol with 3 to 6 carbon atoms as a hydrotrope. WO 93/08247 (Clorox) describes systems based on thickened AES by adding a suitable amount of electrolyte. EP 574 086 (Colgate) describes how the proportion of salt in a composition affects the viscosity. WO 95/02664 (Jeyes Group) describes a liquid concentrate, which when diluted in water, produces a thickened product. The concentrate contains (a) an alkyl sulfate ether, (b) optional components such as anionic, nonionic or amphoteric surfactants, (c) an optional cationic surfactant either alone or in combination with a nonionic surfactant; and (d) an electrolyte or hydrotrope. Patent Application PI 9503351-3 (Unilever NV) discloses a method for handwashing dishes, exclusively for use as a household sanitizing agent, including the step of treating an absorption vehicle with a surfactant which is thickened when water is added. Patent Application PI 9501520-6 (Unilever N.V.) discloses a detergent compound, based on sodium ether lauryl sulfate, lauryl sulfate, amphoteric surfactant, electrolytes and hydrotropes. WO 95/00116 (The Procter &; Gamble Co.) describes a personal safety system, which uses a specific polymer sponge together with a liquid personal hygiene composition composed of skin conditioners, moisturizing creams and surfactants. This invention relates exclusively to the function known as "2 in 1" (combined cleaning and hydration) together with a special sponge in the personal bath. A possible solution to the situation described in the above may be to produce compositions with higher viscosity, but this could make the product harder to remove from the soap dispensers since the viscosity tends to keep the product within the suppliers. The production of high viscosity compositions may also typically require the installation of suitable industrial facilities, since conventional liquid product lines do not have stirring systems and / or bottlers, which are suitable for high viscosity products.

* The state of the art does not describe the existence of any personal hygiene system, associated with the application of vehicles such as sponges, which join the above properties to maximize the performance of the products usable through the use of the process synergistic of the present invention. The present invention is therefore directed to overcome the problems outlined in the foregoing. According to a first aspect the present The invention provides a synergistic personal hygiene process comprising the steps of combining a cosmetic cleansing composition with an application vehicle, the cosmetic cleansing composition comprising: (i) from 7% to 35% by weight based on the total weight of the cosmetic cleaning composition; 15 the composition of one or more anionic, amphoteric or nonionic surface active agents sensitive to thickening through electrolyte, or mixtures thereof, (ii) from 2% to 25% by weight of electrolyte, (iii) up to 25% by weight of active additives, 20 (iv) water. According to a second aspect, the present invention provides a cosmetic cleansing composition as described in the first aspect. According to a third aspect, the present invention provides a personal care product comprising a cosmetic cleansing composition as described in the first aspect together with an application vehicle as described in the second aspect. The novel liquid compositions have the characteristics of increasing the viscosity during use, when they are applied synergistically with a special application vehicle and in the presence of water. This increases the tendency of the composition to remain in the vehicle, thereby increasing the performance available to the consumer to use, and providing an improved cost / benefit ratio. It also avoids the unnecessary impact on the environment and additional capital investment in the production line. In addition, it has been found that certain ranges of electrolyte concentration, excellent viscosity results can be obtained and consequently give a greater yield of the product during use for the consumer. The benefits of this technology can be explored to a greater degree when used with compositions which, as well as necessary components for hygiene and cleanliness, contain active additives responsible for hydration, nutrition, softening, protection and revitalization. Since the compositions of the present invention increase the viscosity during use, the active ingredients are retained for a longer time in the application vehicle and are gradually released so that they can fully perform their function without a significant amount of waste. Typically, the personal care composition of the present invention contains surfactants, electrolytes, active ingredients and water.

The results of technical and comparative tests are duly graphed in the graph and tables given in the figures of the present application. The present invention will now be described with reference to the following examples. The examples are not intended to limit the scope of the invention and modifications within the scope of the present invention will be obvious to those skilled in the art.

The emplos Tests and comparisons were carried out to exemplify the product of the present invention using a number of variations for the composition of the present invention with a range of application vehicles employed. An example of an application vehicle is the "SP500 body sponge mesh" made by Sponge Factory SA. This sponge is made of low density polyethylene, ethylene vinyl acetate and dye.

'* -' Example 1 Several technical tests are carried out using the following composition: H in The effect of the electrolytic concentration (NaCl) on the viscocity of the composition was investigated and the results are plotted in the graph shown in Figures 1 and 2.

* At the end of the description, there are the graphs and tables that are mentioned below. The viscosity of the compositions of Example 1 was measured through two different viscometers; Brookfield (see graph 1) and Haake (see graph 2). With the gradual increase in the concentration of sodium chloride, the viscosity of the compositions reaches a peak with some ? - ^. electrolyte concentration (5.5% by weight of sodium chloride with the Brookfield viscometer and 7% by weight with the Haake), after which the viscosity began to fall. This is a known phenomenon. However, it can be seen that the reverse part is also true, and a liquid composition containing an excess of electrolyte (ie, which is found at a point after the peak on graphs 1 and '"Tß 2), which is diluted with a known amount of water, exhibits inverted behavior and the viscosity increases to a certain point of dilution before falling.This is illustrated through the results shown in graph 3, where a composition with 9.5% in Sodium chloride weight was diluted to the following composition proportions: water: 100: 1, 90:10, 80:20, 70:30, 60:40 and 50:50 The viscosity of each dilution was measured in a viscometer Brookfield.

* The composition in graph 3 reaches its peak of thickening with the dilution ratio of 70:30. When this novel composition is used with a vehicle, such as a sponge, the product will be thickened in the cavities of the sponge and will thus be retained therein over a long period. In this way, the composition will be supplied in higher quantities for the user than conventional products which are much more easily # Rinsings before being properly used by the consumer. The low, electrolytic state concentration of the liquid soap products of the technique causes their viscosity values to appear before the peak on the viscosity curve (see graphs 1 and 2), that is, on the positive inclination that appears in the rinse section of the graph. They do not show the beneficial effects of the compositions of the present, which are in the concentration range just after the peak on the graph, that is to say in the negative inclination that appears in the falling section of the graph. Using the above data, two tests were designed to evaluate the performance of the compositions herein compared with those of the state of the products of the art. These tests are given in the Examples 2 and 3. The performance of the compositions of the present invention and those of the prior art for retaining liquid in the sponge and also for rinsing ability, was tested.

The second The potential for retaining the liquid compositions within the sponge was measured both for a composition according to the present invention and a composition that represents the state of the product of the technique. The tests were carried out with a composition of Example 1 comprising 9.5% by weight of Sodium Chloride (ie, it is within the concentration range located after the peak in graphs 1 and 2). The other composition was a composition of the state of the art, which had an electrolytic concentration of 3% by weight of sodium chloride (ie, it is within the concentration range located before the peak of graphs 1 and 2). 20 The retention potential is shown by the number of glasses or beakers required to complete the rinsing of the product from the sponge application vehicle. A complete rinse was obtained when no foam was formed. From the tests, the performance of the product supplied to the consumer during the time. The following test method was used to analyze the potential for the liquid to be retained in the sponge.

Method 1. 200 ml of water were drained at 40 ° C (or 25 ° C) in a series of six 1000 ml glass precipitates. The sponge vehicle was submerged in the water, stirred and was stirred to release the maximum amount of water in order to leave the sponge merely moist. 2. Weighed and placed 3 g of the product that will be tested on the sponge on the opposite side of a strip. The sponge was then held by the strip, placed in the first 1000 ml glass beaker and filled with water ten times. The sponge was then squeezed by hand with the water and the thus released foams trapped in the first beaker. 3. This procedure was repeated using a new 1000 ml glass beaker until the sponge was completely rinsed and left without foam. 4. The volumetric amount of foam in each beaker was measured and the number of beakers taken was recorded until no foam formed.

. In order to verify the accuracy of the previous test method, the entire procedure was repeated five more times until the measurements showed variations less than 50 ml of foam. 5 Results The results of the above test methods are shown in tables 4 and 5, and graphs 4A, 5A, 6 and 7.

Tables 4 and 5 show the results of the composition of the present invention (comprising 9.5% sodium chloride) compared to the prior art composition (comprising 3% sodium chloride). The results are given at 40 ° C (graph 5) and 25 ° C (graph 6).

Graphs 6 and 7 compare the behavior of the two compositions at both 25 ° C and 40 ° C, respectively. For compositions of the state of the art, which comprise 3% sodium chloride, a lower volumetric reading was observed for the average total foam compared to the average total foam recorded for the compositions of the present invention (comprising 9.5% sodium chloride). The prior art composition produced 945 ml of foam compared to 1085 ml of foam produced by the composition of the present invention when measured at 40 ° C; this represents an increase of 12.9%. The prior art compositions produced a total volumetric foam average of 745 ml compared to 995 ml of foam produced by the compositions of the present invention when measured at 25 ° C; this represents an increase of 25.1%. On average, the compositions of the present invention produce 19% more foam, taken together with the temperature range of 25 ° C to 40 ° C. The results illustrate that the compositions according to the present invention, when used with a sponge application vehicle, provide a better performance of the product to the consumer. The product of the present invention is retained for a longer period in a sponge than that of the prior art compositions, it is believed that this is because the product of the present invention thickens in the cavities of the sponge when gets in contact with water.

Example 3 The rinsing capacity of the composition of the present invention and of the prior art was tested as in Example 2, using the following method. Commercial products of the prior art for body or skin hygiene were also tested as follows: Formula A (Brazil), Formula B (Brazil), Formula C (United States of America), Formula D (Brazil), Formula E (Germany), Formula F (Thailand), Formula G (China).

Method 1. 200 ml of water at 40 ° C were drained in a 1000 ml beaker. A sponge as used in the Example 2, it was soaked in water, stirred and stirred to release the maximum amount of water in order to leave the sponge merely moist. 2. Weighed and placed 3 g of the product that will be tested on the sponge on the opposite side of the strip. The sponge was then held across the strip, placed in the beaker and moved back and forth. * 3. The sponge was held in both hands, it was squeezed five times, while opposite circular movements were made to drain the water from the sponge. 4. An additional 20 ml of water was added at 40 ° C and 5 the sponge was squeezed five times more in the same way. This was repeated until the sponge was completely rinsed. The number of aliquots of 20 ml of water required to rinse the product from the sponge was recorded. ? In order to verify the accuracy of the method Above, the method was repeated three times, or until the results varied by less than 20 ml of water. The results of the rinsing capacity tests are shown in tables 8, 9, 10 and 11 and graphs 8A, 9A, 10A and HA. The composition of the present invention (with a higher electrolytic concentration) took more time to rinse than the others, with the need to form an average of 14.33 aliquots of 20 ml of water to provide a complete rinse. On average, prior art compositions required 10.33 aliquots of 20 ml to provide sufficient rinsing. As shown in table 8 and graph 8A, when compared with the products of the state of the art, the # product of the present invention produced 27.9% more in terms of rinsing capacity. All products of the prior art share the same behavior as that used in the composition of Example 2 comprising 3.5% NaCl. The compositions of the present invention are shown to provide a higher performance to the consumer than the compositions of the state of the art, since the former takes a longer time to rinse off the sponge. It can be appreciated that the product of the present invention has an increased viscosity and is retained for a longer period in the cavities of the sponge, is more difficult to rinse, and gives a higher yield and better production than the prior art compositions. . 15 Example 4 The preparation of the method for the compositions of the present invention may vary in relation to the temperature, pressure, stirring methods, number of premixes, filtration, order and site of addition of either premixes or components, etc. An example of preparation of a composition of the present invention is given in the following.

To the homogeneous product, to adjust the viscosity, 1900 kg of saline water (25% sodium chloride solution) were added. The saline solution was added quickly in order to prevent the high viscosity from being represented by the peaks in Figures 1 and 2.

Example 5 Another composition was prepared according to the present invention following the method given in the following. 15 1-. 2922 kg of LESS (20.7% active) were added to a main tank, which was heated to 60 ° C with moderate agitation. 2. 250 kg of water were emptied into an auxiliary tank of 350 kg and heated to 60 ° C with 9.6 kg of carbopol Aggregates were added under constant stirring followed by 50 kg of LESS (27% active) and the mixture was stirred until all the carbopol groupings were dissolved. This solution was then added to the main tank. 3. 150 kg of water was emptied into an auxiliary tank of 350 kg and heated to 65 ° C. 144 kg of a mixture of ethylene glycol mono and distearate and 50 kg of LESS were added to the water. Stirring was continued until the ethylene glycol mono and distearate was dissolved. This mixture was then emptied into the main tank and the product in the main tank was stirred until homogeneous. 4. 154.9 kg of water were added to an auxiliary tank of 250 kg, with 4.8 kg of Jaguar C13S under constant agitation, again a small solution of sodium hydroxide (49%), was added to help dissolve the Jaguar and adjust the pH to more than 10. The premix of Jaguar C13S was added to the main tank followed by 240 kg of silicon emulsion (50% active). 5. A premix of 48 kg of perfume, 6.3 kg of formaldehyde and 2.4 kg of BHT was prepared in an auxiliary tank of 100 kg with the mixture stirred until the components were completely dissolved. When the temperature of the composition in the main tank fell below 40 ° C, the perfume premix / BHT / formaldehyde was added followed by 480 kg of cocoamidopropylbetaine. 20 6. 288kg of saline was added to the main tank to increase the total weight of the composition to 4800kg. 6 7 10% NaCi Brookfield Viscometer LVff Graph 1 VISCOSITY CHART effect of electrolytic concentration on viscosity 7 10 1 1% NoCI viscos ímetro _-] GRAPH 2 velßci-22.6 cm "dad. 100% 90/10 80/20 70/30 60/40 50/50 dilution of the invention composition / water BrookfieldLVT visiosimers * graph "3 - Potential for challenging the liquid in the sponge formula of the prior art by formula of the invention * Temperature: 25 ° C twenty 3 5 TABLE 4 INVENTION (9.5% NaCl) re i ipiepte 1 container ^ container ^ container 4 container 5 container 6 CHART < IA - - potential for retaining the liquid in the sponge Formula of the prior art x Formula of the invention ° G temperature PREVIOUS TECHNICAL TABLE (3.0% NaCl) * 60 01 O c -1 ¡200 > or recipien? container container 3 container 4 recipeinte 5 container 6 invention (9.5% NaCl) container 1 container "2 container." 3 container * container '5 container GRAPH 5A < * POTENTIAL FOR RETAINING THE LIQUID IN THE FORMULA SPONGE OF THE PREVIOUS TECHNIQUE by INVENTION at 25 ° C container. -J container 2 container 3 container container container pterior technique (3.0% NaC!) - ^ - invention (9, 5% NaCl) CHART 6 - < * • POTENTIAL FOR THE DELAY OF LIQUID IN THE ESPOJA FORMULATION OF THE PREVIOUS TECHNIQUE BY INVENTION AT 10 ° C container! container '2 container 3 container 4 container container previous technique (3.0% NaCl) -o- invention '(9.5% NaC!)
