Description

Body cleaning system comprising a diamond net bath sponge and a liquid detergent containing a halogenated biocide

It is well known to use a sponge or system tool to apply a soap liquid cleaning composition to the body. Hudson et al. US Pat. No. 5,295,280 discloses, for example, a cleaning tool for scrubbing the body. The cleaning element (ie the sponge) has a substantially uniform cross section and a substantially porous internal structure that allows water and soap to penetrate the surface and the interior thereof (2 columns, lines 28-31). US Pat. No. 5,144,744 to Campanoli also discloses sponges (particularly diamond-shaped polyethylene polyethylene sponges) which are clearly designed for bath use (see claim 1).

International Publication 95/00116 (assigned to Procter & Gamble) relates to a body cleansing system comprising a diamond-like net bath sponge used with a liquid cleanser comprising a moisturizer. Diamond-shaped net sponges are known to enhance the foaming properties of cleaning agents including humectants.

On page 12 of the international patent application it is mentioned that antimicrobial agents can be optionally added. There is no mention of any particular antimicrobial agent or the recognition that sponges may enhance the deposition of certain bacteriostatic agents, ie halogenated (preferably chlorinated) bacteriostatic agents.

Finally, Dial Company has marketed liquid cleaners with chlorinated bacteriostatic agents since approximately January 1995. Applicant conceived and completed the present invention prior to this date.

Summary of the Invention

Applicant has now unexpectedly discovered that certain bacteriostatic agents, ie halogenated bacteriostatic agents, can be easily applied and dispersed using, for example, a diamond-like net bath sponge as disclosed in US Pat. No. 5,144,744 to Campanoli.

The present invention finds that when applying any bacteriostatic agent, including a liquid detergent, to the body / skin using a hand held lightweight polymeric net sponge, the deposition / delivery of the bacteriostatic agent is better than when delivered to the normal sponge. It is about. That is, the sponge synergistically interacts with the liquid detergent and bacteriostatic agent to enhance delivery of the bacteriostatic agent. The liquid detergent containing the bacteriostatic agent and the net sponge are packaged together as a kit. The liquid detergent is usually contained in a large amount of individual containers sufficient for multiple uses as a sponge.

More specifically, the cleaning system for the body bath or shower comprises the following (A) and (B) components.

(A) a hand held lightweight polymeric net body cleaning sponge; This polymeric net sponge is in a form suitable for use as a hand held cleaning tool, the hand held sponge having a diameter of about 2 to about 8 inches (5.08 cm to about 20.32 cm); Preferably the hand held polymeric net body scrubbing polymeric net sponge is made of polyethylene diamond-shaped nets and has a diameter of 3 to 5 inches (7.62 cm to about 12.7 cm).

(B) (1) an effective amount of surfactant selected from the group of synthetic surfactants and mixtures thereof; And

(2) bactericides, preferably halogenated bactericides, more preferably bactericides selected from the group of halogenated bactericides described below

Liquid detergent comprising a.

The combination of polymeric net sponge and detergent and bacteriostatic agent enhances the deposition of bacteriostatic agent. In other words, the sponge interacts with bacteriostatic agents to enhance deposition / delivery in a better way than other forms of sponge.

Sponge

Cleaning polymeric net sponges can be made from readily available materials or specially designed net materials. Preferably, polymeric net sponges are prepared from tubular nets extruded from particularly strong and stretchable polymeric raw materials. Extruded tubular nets of this type, and especially those made from polyethylene, have been used as cover for meat of livestock and poultry and are readily available in industry.

Polymeric net sponges include extruded tubular nets made from strong stretchable polymers; It preferably comprises a plurality of plies of the group consisting of addition polymers of olefin monomers and polyamides of polycarboxylic acids and polyamines, which are folded several times to form a soft spherical polymeric net sponge.

Tubes or strings of reticulated net polymers should be securely bonded with nylon straps or appropriate closures. This form of polymeric net sponge was disclosed in US Pat. No. 4,462,135 to Sanford, July 31, 1984, which was incorporated herein by reference.

An example of a spherical polymeric net sponge held in hand is disclosed in US Pat. No. 5,144,744 to Campanoli, Sep. 8, 1992, which was incorporated herein by reference. Diamond-shaped net polyethylene sponges that are obtained from many reticulated tubes that extend around a support, are connected and tied together at the center, and then dismantled from the support.

A commercially available "polymeric net sponge" is available from The Body Shop and Bynum Concepts, Inc. Other suppliers include Supremia Use in New Jersey, Sponge Factory Dominicana in the Dominican Republic, and Integrated Marketing Group in Harrison, New York.

Not all, but the specifications for a suitable bath polyethylene polymeric net sponge are as follows:

diameter tube Each length Total length Weight (gm) 7.62 cm 2 60 cm 120 cm 15 10.16 cm 4 50 cm 200 cm 23 12.7 cm 4 80 cm 320 cm 37

The ease with which the cleaning polymeric net sponge can be held at the time of cleaning is shown in FIG. 2. The safety belt 13 bundles the multilayer net together to form a polymeric net sponge. Nets that can be used to make polymeric net sponges are shown in FIG. 3. Here, 21 represents the net in the extended state. The thin polymeric filaments used to make the mesh are shown as 18 and the point bonds of the filaments are shown as 19 to form an open net 20.

Two reticulated tubes each 60 cm long can be used to make a 3 inch spherical sponge. It can be tied by hand using rings or ropes to form a spherical polymeric net sponge. Other designs, such as rectangular gloves made of net material and cleaning tools, also work very well in the system of the present invention.

Within the broad category of liquid active agents, alkyl sulfates, alkyl ether sulfates, alkyl ether sulfonates, sulfosuccinates, and amidopropyl betaines are most effective.

Acyl isethionate having the following formula is another preferred surfactant.

Wherein R represents a straight chain or ground alkyl group and M represents an alkali metal or alkaline earth metal or amine.

Other surfactants that can be used are monoalkyl or dialkylphosphate surfactants.

Another soft surfactant that can be used, preferably with the other surfactants listed above, can be used as the main surfactant is sodium coco glyceryl ether sulfonate. While preferred for use due to its ductile properties, this Coco AGS alone does not provide the optimum foam cream. Alkyl AGS distribution of sodium 90/10 coconut / resin is preferred for creaming. Salts other than sodium salts such as TEA-, ammonium, and K-AGS and chain length distributions other than 90/10 coconut / resin are available at appropriate levels. In addition, some soap may be added to improve foam volume and foaming speed. Any second co-surfactant used with AGS can also provide a more creamy and safe foam. This second surfactant should also be essentially soft. A second surfactant found to be particularly preferred is sodium lauroyl sarcosinate (Hamposyl L, manufactured by Hampshire Chemical).

The amphoteric betaines and sultaines specified above can be used as surfactants alone, but are more preferred as auxiliary surfactants. If high foam is desired, nonionic surfactants cannot usually be used as sole surfactants in this product; However, nonionic surfactants can be included as auxiliary surfactants.

Nonionic and cationic surfactants that may be used include those described in US Pat. No. 3,761,418 to Parran Jr., which is hereby incorporated by reference. Also aldobiamides described in US Pat. No. 5,389,279 to Au et al .; Polyhydroxy fatty acid amides described in US Pat. No. 5,312,934 to Letton, which are incorporated herein by reference.

Soap may be used at a level of about 1-10%. If the surfactant mixture is softer than soap, then soap can be used at higher levels. Free fatty acids can be converted by appropriate addition of soap or by addition of a base such as NaOH. Of course, as described above, soaps should only be used as auxiliary surfactants to the extent that the surfactant system is softer than the soap itself.

Preferred surfactant systems include 1-15% by weight acyl isethionate of the total composition, anionic surfactants other than 1-15% by weight acyl isethionate of the total composition (eg ammonium lauryl ether sulfate) and And from 0.5 to 15% of the amphoteric surfactant of the total composition.

Another preferred active system is one containing 1-20% alkyl ether sulfate. Preferred surfactant systems may also include 1 to 10% alkali metal lauryl sulfate or C ₁₄ -C ₁₆ olefin sulfonate instead of acyl isethionate.

Other preferred cleaning and moisturizing cleaning compositions

(a) 8 to 35% polyols;

(b) 35 to 70%, preferably 45 to 65% water;

(c) 5 to 20%, preferably 7 to 19%, nearly poorly soluble saturated (low iodine value of 0 to 15) C ₈ -C ₂₂ fatty acid potassium soap;

(d) 0.1 to 7%, preferably 0.5 to 5% of free C ₈ -C ₂₂ fatty acids; And

(e) 0.5 to 5%, preferably 0.7 to about 4.5% of petroleum jelly

And mixtures thereof.

Polyols include glycerin, glycerol, propylene glycol, polypropylene glycol, polyethylene glycol, ethyl hexanediol, hexylene glycol, and other aliphatic alcohols; And mixtures thereof. When propylene glycol is used as a moisturizer, it should be used at a level of at least 5%. Polyols are preferably used at levels of about 10 to 30%.

Liquid detergents include petrolatum; Fatty acid esters; Glycerin mono-, di, and tri-esters; Epidermal and fatty hydrocarbons such as cholesterol, cholesterol esters, squalene; Silicone oils and gums; Mineral oil; Lanolin, derivatives, and the like and mixtures thereof, from about 0.5% to about 15%.

Mixing larger sized petrolatum particles into a selected fatty acid / soap matrix yields a preferably improved stable product with the benefit of moisturizing. Larger petrolatum particles will change for liquids or semisolids. The important thing is to choose a fatty acid and / or soap matrix and mix it in petrolatum using a minimum amount of shear stress to maintain larger petrolatum particles and obtain a homogeneous stable product, for example an improved benefit It is also obtained in a semisolid cleaning cream.

Preferably all (free and neutralized) fatty acid materials used in liquid detergents have an iodine value (I. V.) of about 0 to about 15, preferably 10 or less, more preferably 3 or less.

Bacteriostatic

The second most important component of the liquid detergent composition, bacteriostatic agent, is usually a halogenated bacteriostatic agent. The first bacteriostatic agent (a chemical that inhibits bacteria that breaks down sweat into nasty ingredients) was applied to soaps in about 1950.

The most widely used are hexachlorophene; Chlorohexidine; 3,4,4'-trichlorocarvanide; 3,4 ', 5-tribromosalylsilanilide; 4,4'-dichloro-3 '-(trifluoromethyl) carbanilide; And 2,4,4'-trichloro-2'-hydroxy diphenyl ether.

The bacteriostatic agent is used in the composition of the present invention in the range of 0.01 to 10% by weight, preferably 0.05 to 5% by weight.

The present invention is directed to an unexpected tube swell that, when the bacteriostatic agent is applied to the net sponge described above, is better dispersed / deposited than when the bacteriostatic agent is applied to other types of sponges.

Other components

The composition for the cleaning bath / shower may include any of a variety of non-essential components suitable for further making the composition. Any conventional component such as preservatives such as benzyl alcohol, methyl paraben, propyl paraben and imidazolidinyl urea; Other thickeners and viscosity modifiers, such as C ₈ -C ₁₈ ethanolamides (eg coconut ethanolamide); PH adjusters such as citric acid, succinic acid, phosphoric acid, sodium hydroxide, and the like; Suspending agents such as magnesium silicate / aluminum silicate; Spices; dyes; And metal ion sequestrants such as disodium ethylenediamine tetraacetate are well known to those skilled in the art.

If present, any component usually constitutes from about 0.001 to about 10 weight percent of the composition, respectively, but may be more or less.

Any thickener is classified as a cationic, nonionic, or anionic thickener and is selected to provide the desired viscosity.

Suitable thickeners are described in 3, 4, 12 and in Glossary and Handbook of Water-Soluble Gums and Resins , Robert L. Davidson, Mcgraw-Hill Book Co., New York, NY, 1980, It is described in Chapter 13.

Using a polymeric additive that hydrates, swells or bonds molecularly, the liquid body cleansing product is thickened to provide to the body (for example, hydroxypropyl guar gum is used as a thickening aid in shampoo compositions).

Suitable thickeners are, for example, hydroxy ethyl cellulose, such as Natrosol R 250 KR sold by The Aqualon Company.

Another thickener is an acrylated styreless-20 methylacrylate copolymer sold as Acrysol ICS-1 by Rohm and Haas Company.

The amount of polymeric thickener found useful in the composition is from about 0.1 to about 2 weight percent, preferably from about 0.2 to 1.0 weight percent.

Liquid detergent 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 derivatives, cationic copolymers of saccharides and synthetic monomers, synthetic copolymers and cationic protein derivatives Can be prepared.

In a second embodiment of the present invention, the present invention provides for the delivery of bacteriostatic agent comprising applying and rubbing a liquid detergent comprising a bacteriostatic agent to the skin or a net sponge, or massaging a site requiring enhanced delivery / deposition with the sponge. It is about how to strengthen the deposition.

Example 5

In order to show that the deposition of bacteriostatic agents (ie, Triclosan® or DP300) is greater when using pouf than when using a sponge, the following experiment was performed.

First, the applicant obtained a composition consisting of the following components.

Component weight % Cocoamidopropyl betaine About 27% Sodium laureth sulfate About 7% Sodium cocoyl isethionate About 6% silicon About 5% water About 53% Aroma, Colorant, Trace Component About 2%

Applicant prepared a 25% solution of the shower gel composition comprising about 2.5 uCi / ml of DP300 (14C-DP300, inactive = 157 uCi / mg) radiolabeled. 1 ml of the shower gel solution was applied to a 1.2 g pouf (round size 40 g) or 0.4 g sponge (round size 12 g) and the pouf and sponge were pressed 20 times to form a bubble. The 12 cm ² piglet skin was washed with pouf or sponge for 30 seconds, rinsed with running water for 30 seconds, and lightly patted with paper towels. The amount of DP300 deposited on the skin was measured by radiomagnetism. The results are as follows.

Pouf = 0.07 ug / cm ² (SD = 0.02); Sponge = 0.03 ug / cm ² (SD = 0.003)

S.D. = Standard deviation (n = 4)

The results clearly show that the deposition when using poufs is higher than that when using sponges.

Example 6

To further demonstrate the enhanced deposition of pouf vs. sponge, Applicants conducted a direct skin disc experiment as follows:

Applicants prepared pig skin (shaved) and applied the product for 30 seconds. Shower gel A is the same as Example 5 and comprises -0.25% triclonic acid; Shower Gel B is a non-sterile product. The treated portions were placed on agar plates seeded with ATCC # 4352 in S. aureus ATCC # 6538 or K. pneumoniae for 30 minutes and then incubated at 34 ° C. for 24 hours. After applying the product, the part was placed on the agar plate for about 15 minutes.

The results are shown in Table 1 below.

Skin disc direct experiment specimen apply Inhibition score (average of three skin parts) S. aureus ATCC # 6538 K. Pneumonie ATCC # 4352 Shower Gel A Pouf 3.83 4.00 Shower Gel A Sponge 0.83 0.00 Shower gel B Sponge 0.00 0.00

For S. aureus, shower gel A applied to pouf is strong in inhibiting organisms. Products applied to sponges (Jergens sponges) prove to be of less value than slight inhibition. As expected, non-sterile shower gel B shows no inhibitory activity.

For K. pneumoniae, shower gel B applied to pouf shows complete inhibition. Shower gel A and shower gel B / sponge applied to the sponge do not inhibit bacteria. (Score = 0)

From the data (see Examples 5 and 6), it is clear that Pouf deposits bacteriostatic agents in a better way than sponges.
