Description

Field of Invention

The present invention relates to a skin cleansing kit comprising a hand bath sponge for personal use and a liquid bath or shower cleanser containing a halogenated biocide or bacteriostat. In addition, the invention includes a method of increasing the deposition of a biocide contained in a liquid detergent using a bath sponge having a mesh with diamond-shaped cells.

Background to the invention

The use of a sponge or device system for applying soapy liquid detergent compositions to the body is well known. US Pat. No. 5,295,280 Nibcop C1 A1. Describes, for example, a washing device for rubbing the body. The washing element (i.e., the sponge) has a substantially uniform cross section and a porous internal structure that allows water and soap to penetrate through the surface and inside of the sponge (column 2, lines 28-31). US Pat. No. 5,144,744 to Satradpoy also describes sponges (in particular a polyethylene sponge with diamond-shaped cells) intended for a bathtub (see paragraph 1 of the claims).

International Application \ ¥ 0 95/00116, owned by Proc & Gamble, Proc. & Gamble, relates to a hygiene kit containing a bath sponge with diamond-shaped cells, used in combination with a liquid detergent containing a moisturizer.

On page 1 2 of this application, it is mentioned that a bactericidal substance may optionally be added. The application does not mention the specific form of the bactericidal additive and does not indicate that the sponge can provide improved deposition of specific bacteriostats, i.e. halogenated (preferably chlorinated) bacteriostats. And finally, E1a1 Sotrapu (Dial Company), approximately from January 1995, launches a liquid detergent with a chlorinated bacteriostat on the market.

SUMMARY OF THE INVENTION

Applicants have unexpectedly discovered that certain bacteriostats, i.e. halogenated bacteriostats can be easily applied and dispersed using a bath sponge having a mesh with diamond-shaped openings, such as that described in US Pat. No. 5,144,744 Sotradpa.

More specifically, the present invention includes a kit or kit for cleaning the skin, containing:

(1) a lightweight polymeric hand-held mesh sponge for personal use to clean the skin, and (2) a liquid cleaner containing:

(a) an effective amount of a surfactant selected from the group consisting of soap, synthetic surfactants (anionic, nonionic, zwitterionic and / or amphoteric, cationic) and mixtures thereof: and (b) from 0.01 to 10 weight. %, preferably from 0.05 to 5% by weight of a halogenated bacteriostat.

According to a second embodiment, the invention includes a method for improving the deposition of a halogenated bacteriostat in a liquid composition containing an effective amount of a surfactant, comprising applying a cleaner containing a bacteriostat to a sponge and / or desired surface (i.e. body) and applying a sponge (with or without a bacteriostat, depending on where the cleaner is added: to the sponge or to the body) to the desired surface. Thus, the cleaner can be applied to the sponge and then applied to the body; or a cleaner can be applied to the body and then rubbed with a sponge.

DETAILED DESCRIPTION OF THE INVENTION

The present invention aims to detect the fact that when liquid detergents containing a specific bacteriostat are applied to the body / skin using a lightweight polymeric manual mesh sponge, these bacteriostats are precipitated / delivered to a greater extent than if they were delivered using a conventional sponge. Thus, the sponge synergistically interacts with a liquid detergent and a bacteriostat, enhancing the delivery of the bacteriostat. A liquid detergent containing a bacteriostat and a mesh sponge are packaged together as a kit. The liquid detergent is usually in a separate container in an amount sufficient for several applications.

More specifically, a personal use system for cleaning skin in a bath or shower includes:

(A) a lightweight polymeric manual mesh sponge for cleaning skin, wherein the polymer mesh sponge is in a form suitable for use as a manual skin cleaning device, wherein the manual sponge has a diameter of about two (2) inches to about eight ( 8) inches (from 5.08 cm to about 20.32 cm); preferably, a personal-use polymeric manual mesh sponge for cleaning skin is made of a polyethylene mesh with diamond-shaped cells and has a diameter of 3 to 5 inches (7.62 to about 12.7 cm); and (B) a liquid detergent containing (1) an effective amount of a surfactant selected from the group consisting of synthetic surfactants and mixtures thereof; and (2) a bacteriostat, preferably a halogenated bacteriostat, more preferably selected from the group of halogenated bacteriostats described below.

The combination of a polymer mesh sponge and detergent with a bacteriostat enhances the deposition of the bacteriostat. Thus, the sponge interacts with the bacteriostat, enhancing delivery / deposition in a more efficient way compared to other types of sponges.

Sponge

A skin cleansing polymer mesh sponge can be prepared from readily available starting materials or using mesh materials specifically designed for this purpose. The polymeric mesh sponge is preferably obtained from an extruded cylindrical mesh, which is obtained from a special strong and flexible polymeric material. An extruded cylindrical mesh of this type, and in particular one that is obtained from polyethylene, is used for packaging meat and poultry, and it is readily available in industry.

The polymer mesh sponge contains many layers of an extruded cylindrical mesh made from a durable elastic polymer, preferably from the group consisting of polymers of olefin monomers obtained by stepwise polymerization, and polyamides of polycarboxylic acids and polyamines, while the layers of the cylindrical mesh fold repeatedly to form a polymer mesh sponge, like a soft ball.

The tubes or strips of cross-linked polymer can be reliably connected by means of nylon tape or by suitable overlap. This type of polymer mesh sponge is described in US Pat. No. 4,462,135, July 31, 1984, ZapGogb. referenced here.

An example of a handmade polymeric mesh sponge that looks like a ball is presented in US Pat. No. 5,144,744 to Satradpa, September 8, 1992, to which reference is made. It is a polyethylene sponge having a mesh with diamond-shaped holes, obtained from a series of mesh cylindrical packs of threads stretched over substrates, joined and connected together in the middle and then separated from the substrates.

Commercially available polymer mesh sponges are sold by TNe Wobu 8yor and Wupit SopserK 1ps. (Dze Body Shop and

Baynam Concepts, Inc.). Other suppliers are 8irtetaa Ike (Supremia Hughes) in New Jersey, 8products of Eas1otu Iotskapa (Sponge Factory Dominican Republic) in the Dominican Republic and 1p1ettta1eb Matkape Stair (Integrated Marketing Group) in Harrison, New York.

The following are some, although definitely not all, descriptions of suitable bath polyethylene polymer mesh sponges:

FIG. 1 is a perspective view of a ball-like polymer hand bath sponge with a diamond-shaped mesh having a rope handle 7 that can be used in the present invention. The ease of holding the polymer mesh sponge for cleaning the skin is shown in FIG. 2. The tightening tape 1 3 holds the integrity of the multilayer mesh, contributing to the formation of a polymer mesh sponge. A mesh that can be used to make a polymer mesh sponge is shown in FIG. 3, where position 21 represents the grid in the stretched position. The thin polymer yarns used to make the mesh are shown at 18, with 1 9 representing the bonding of the threads to form a mesh with open mesh 20.

For the manufacture of a 3-inch (7.62 cm) ball net, two cylindrical mesh packages can be used, each of which has a length of 60 cm. They can be manually tied using a rope or loop to form a polymer-like mesh sponge. Other designs can also be used in the kit of the present invention, and rectangular gloves and cleaning supplies made of mesh material can be used.

Surfactant Liquid Detergent System

The present invention relates to liquid skin cleansing compositions containing from 1 to 99 wt.%, Preferably from 2 to 85%, more preferably from 3 to 40% of a composition of soft surfactants containing one or more surfactants, the clinical trials of which individually or together, during which they carried out a test for the solubilization of zein, showed that they are softer than the soap itself (soap gives 80% solubilization of zein). The softness is preferably such that the solubilization of zein is in the range of 10-60%. At least,

10%, preferably at least 25%, relative to the total weight of the surfactant composition should be an anionic surfactant. According to theory, as long as the anionic surfactant is softer than the soap itself, 10% of the surfactant composition may be anionic.

In the system of surfactants of the invention, provided that the surfactant or mixture of surfactants is softer than the soap itself, a series of anionic, nonionic, cationic and zwitterionic and / or amphoteric surfactants can be used in the Zein solubilization test.

Suitable anionic co-active agents are alkyl ether sulfates, acyl isethionates, alkyl ether sulfonates, sarcosinates, sulfosuccinates, taurates and combinations thereof. Suitable amphoteric substances may include alkyl betaines, amidopropyl betaines, amidopropylsultaines, and combinations thereof.

The alkyl ether sulfates of the present invention have the general formula K- (OCH ₂ CH ₂ ) _n O ₈ O ₃ —M ^, where K is C ₈ -C ₂₀ alkyl, preferably C ₁₂ -C ₁₅ alkyl, η is an integer from 1 to 40, preferably from 2 to 9, optimally about 3, and M 'is a cation of sodium, potassium, ammonium or triethanolammonium.

Within a large category of liquid active substances, alkyl sulfates, alkyl ether sulfates, alkyl ether sulfonates, sulfosuccinates and amidopropyl betaines are most effective.

Another preferred surfactant is an acyl isethionate having the formula o

II

K - C - O - CH ₂ - CH _g - 30 -, And in which B represents a linear or branched alkyl group, and M represents an alkali metal or alkaline earth metal or amine.

Other surfactants that may be used are monoalkyl or dialkyl phosphate surfactants.

Another mild surfactant that can be used preferably as the main surfactant in combination with the other surfactants mentioned above is sodium cocoglyceryl ether sulfonate. Although it is desirable to use this substance because of its softness, AC8 alone does not provide the optimal density of soap suds. To obtain a thick soapy foam, it is preferable to distribute sodium coconut alkyl and tall oil alkyl at a ratio of 90/10 in sodium AC8. Salts other than sodium are also suitable for moderate concentrations, for example, TEM, ammonium and K-AC8 salts, and the chain length distributions of coconut oil alkyl and tall oil alkyl in these cases will be different than 90/10. Soap can also be added to increase the volume of soap suds and the rate of their formation. A thicker and more stable soap foam can also be provided by secondary surfactants used in combination with AC8. These secondary surfactants must also be inherently soft. One particularly desirable secondary surfactant is sodium lauroyl sarcosinate (trade name Natroguy L, manufactured by Nashrkut Siesh1sa1).

The amphoteric betaines and sultaines mentioned above can be used as the sole surfactant, but their use as a secondary surfactant is more preferred. If significant foaming is desired, nonionic surfactants in the form of a single surfactant should usually not be used in this product; however, they can be included as a secondary surfactant.

Non-ionic and cationogenic surfactants that can be used include one of those described in US Pat. No. 3,761,418 to Parran Jr., which is incorporated herein by reference. They also include aldobionamides, which are described in US patent No. 5389279 Au and others, and polyhydroxyamides of fatty acids, which are described in US patent No. 5312934 Letton and others, both of which are included in the application for reference.

Soaps can be used at levels of about 1 to 10%. When a surfactant mixture is softer than soap, soaps can be used at higher levels. For the conversion of free fatty acids, soaps can be added in pure form or obtained ίη δίΐιι by adding a base, for example, ΝαΟΗ.

Of course, as mentioned above, soaps should be used as secondary surfactants to such an extent that the composition of surfactants is softer than one soap.

A preferred surfactant composition is one that contains an acyl isethionate in an amount of from 1 to 1 5 wt.% Relative to the weight of the whole composition, other than an acyl isethionate, an anionic surfactant (e.g., ammonium lauryl sulfate) in an amount of from 1 to 1 5 wt.% relative to the weight of the whole composition and amphoteric surfactant in an amount of from 0.5 to 15 wt.% relative to the weight of the whole composition.

Another preferred active composition is one which contains from 1 to 20% alkyl ether sulfate. Preferred surfactant compositions may also contain, in place of the acyl isethionate, from 1 to 10% lauryl sulfate or C ₁₄ C1 ₆ alkali metal olefin sulfonate.

Another preferred composition for cleansing and moisturizing the skin may contain ingredients selected from the group consisting of (a) from 8 to 35% polyol;

(b) from 35 to 70%, preferably from 40 to 65% by weight of water, (c) from 5 to 20%, preferably from 7 to 19%, of the usually insoluble saturated potassium fatty acid soap (with a low iodine number from 0 to 15 );

(b) from 0.1 to 7%, preferably from 0.5 to 5% of free fatty acids; and (e) from 0.5 to 5%, preferably from 0.7 to about 4.5% of petrolatum, and mixtures thereof.

The polyol is selected from the group consisting of glycerol (disepp), glycerol (§11seto1), propylene glycol, polypropylene glycol, polyethylene glycol, ethylhexanediol, hexylene glycol and other aliphatic alcohols and mixtures thereof. When propylene glycol is used as a humectant, it is used in an amount of at least 5%. Polyols are preferably used in amounts of about 10-30%.

The liquid detergent may contain from about 0.5 to about 15% of a lyophilic emollient moisturizer selected from the group consisting of petrolatum, fatty acid esters, glycerol mono-, di- and triesters; epidermal and sebaceous hydrocarbons, for example, cholesterol, cholesterol esters, squalene; silicone oils and resins; mineral oil; lanolin and derivatives, etc. and mixtures thereof.

A preferred improved stable moisturizing product is obtained by incorporating larger, sorted particle sizes of petrolatum into selected fatty acid / soap matrices. Larger particles sorted by size can be in the form of a liquid or in a semi-solid state. The solution to the problem is to select a matrix of fatty acid and / or soap and to intervene in the petrolatum using a minimum controlled shear force to preserve the larger particles of the petrolatum and obtain a homogeneous, stable product, for example, good results are also obtained when using a semi-solid skin cleansing cream .

The fatty acid substance (free and neutralized) used in the liquid detergent preferably has an iodine value (Ι.ν.) of from zero to about 15, preferably less than 10, more preferably less than 3.

Bacteriostat

Bacteriostats, which are the second important component of a liquid detergent composition, are typically halogenated bacteriostats. Since about 1950, bacteriostats (chemicals that control bacteria, which in turn cause sweat to decompose into components with an unpleasant odor) were introduced into the bars of soap. The most commonly used bacteriostats are hexachlorophene; chlorhexidine; 3,4,4'-trichlorocarbonylanilide; 3,4 ', 5-tribromosalicylanilide; 4,4'-dichloro-3 '(trifluoromethyl) carbanilide; and 2,4,4'-trichloro-2'oxydiphenyl ether.

The bacteriostat in the compositions of the invention is used in an amount of from 0.01 to 10 wt.%, Preferably from 0.05 to 5 wt.%, Relative to the weight of the composition.

The present invention is based on the unexpected observation that these bacteriostats, when applied using the mesh sponge described above, dispersed / precipitated much better than if they were applied using other types of sponges.

Other ingredients

Hygiene bath or shower compositions may contain a variety of minor optional ingredients suitable to make such compositions more desirable. Such conventional optional ingredients are well known to those skilled in the art, and they are, for example, preservatives such as benzyl alcohol, methyl paraben, propyl paraben and imidazolidinyl urea; other thickeners and viscosity modifiers, for example, C ₈ -C 1 ₈ ethanolamide (e.g. cocoethanolamide); pH adjusters, for example citric acid, succinic acid, phosphoric acid, sodium hydroxide, etc .; suspending agents, for example, magnesium / aluminum silicate; perfumes, dyes; compounds that bind a metal ion to a chelate complex, for example disodium ethylene diamine tetraacetate.

If present, each of the optional ingredients is usually contained in an amount of from about 0.001 to about 10% by weight relative to the weight of the composition, but their content may also be more or less.

Optional thickeners can be divided into cationic, nonionic or anionic and are selected to provide the desired viscosity.

Suitable thickeners are listed in the dictionary of the book and in chapters 3, 4, 12, and 13 of the book Napbiook οί ^ a! Er-8o1i1e Sitk apb Vekshk, Voei b., Όανί68οη, Ms Sga \\ - NP1 Vook Co., Youte Wogk, Ν. Υ., 1980, which is incorporated by reference.

Personal hygiene liquid products can be thickened through the use of polymer additives that hydrate, swell or bind to form a body (for example, hydroxypropyl guar gum is used as a thickening agent in shampoo formulations).

A suitable thickener is hydroxyethyl cellulose, for example No.-Ngo8o1 B 250 KV, sold by Thieu Ac. | Alaop Sotrapu (Dze Aqualon Company).

Another thickener is an acrylic-containing copolymer of stearyl-20 methacrylate sold by Voigt apb Naak Sotrapu (Rum and Haas Company) under the name Asguko1 18C-1.

The amount of polymer thickener useful in the present compositions is from about 0.1 to about 2%, preferably from about 0.2 to about 1%.

The liquid cleaner may contain from about 0.1 to about 5%, preferably from about 0.3 to about 3%, of a skin moisturizing cationic polymer selected from the group consisting of cationic polysaccharides and their derivatives, cationic copolymers of saccharides and synthetic monomers, synthetic copolymers and cationic derivatives of the protein.

According to a second embodiment, the invention relates to a method for enhancing the delivery / deposition of a bacteriostat, comprising applying said liquid detergent containing a bacteriostat to the skin or mesh sponge and rubbing or massaging said sponge over the entire surface of the area where enhanced delivery / deposition is desired.

More specifically, the method includes applying to a substrate selected from the group consisting of skin, a polymer mesh sponge and combinations thereof, a liquid detergent containing (1) an effective amount of a surfactant selected from synthetic surfactants and mixtures thereof; and (2) a halogenated bacteriostat; and rubbing with a polymer mesh skin sponge to dispense a liquid cleaner.

The liquid cleanser / compositions and bacteriostat are as defined above.

Unexpectedly, it was found that the mesh sponge delivers larger amounts of bacteriostat than those delivered using other types of sponges.

The following examples are intended to further illustrate the invention, and not to limit it.

Applicants prepared a 25% solution of a shower gel of the aforementioned composition containing about 2.5 iC1 / ml labeled with a ΌΡ 300 radioactive isotope (MS-ΌΡ 300, specific activity = 157 iC1 / mg).

ml of shower gel solution was applied to 1.2 g of fluffy washcloths (initial weight of 40 g) or 4 g of sponge (initial weight of 12 g), and the fluffy washcloth and sponge were squeezed 20 times to create a soapy foam. The pigment’s back skin area of 12 cm ² was washed with a fluffy washcloth or sponge for 30 s, then rinsed with running water for 30 s and wiped on the back with a paper towel.

The amount of ΌΡ 300 deposited on the skin was determined using automatic radiography, the results are presented below.

Fluffy washcloth = 0.07 g / cm ² (standard deviation = 0.02);

sponge = 0.03 ig / cm ² (standard deviation = 0.003);

Shower gel A, applied to a fluffy washcloth and applied against Z. aigeiz, provided complete inhibition of microorganisms. The product applied with a sponge (sponge from Jergenz (Igrzepz)) showed less than weak inhibition. As expected, Shower Gel B, which does not kill bacteria, did not show inhibitory activity.

Shower gel A, applied with a fluffy washcloth and applied against K. rpeisoshae, provided complete inhibition. Shower gel A applied with a sponge and shower gel B applied with a sponge did not inhibit bacteria (the inhibition value is 0).

From these data (see examples 5 and 6) it is clear that the bacteriostat settles on a fluffy washcloth much better than on a sponge.
