Abstract

A liquid denture cleanser composition comprising an aqueous solution of sulfated fatty alcohol detergent, a chelating agent of the amino carboxylate or organo phosphonate type. The cleanser is preferably dispensed from a mechanical spraying device such that the force of the spray supplements the cleansing effect of the composition.

Description

DETAILED DESCRIPTION OF THE INVENTION A liquid detergent composition comprising: (b) an aminocarboxylate or organic phosphonate chelating agent; and (Q) from about 50% to about 98% water. The composition is intended to be delivered to the surface with a spray pump system or device. The detergents of the present invention are particularly useful as denture detergents.

Prior art regarding denture detergents has focused on the combined use of oxidizing agents and bleaching agents to remove visible dirt and dental plaque or plaque products.

Typically, these compositions employ various sulfates such as pisulfate and monosulfate for use as detergents and oxidizing agents, as well as alkali metal and alkaline earth metal nolides as bleaching agents. It's here. Perborate, carbonate, picarbonate and phosphate salts were conventionally included to provide frothing and activation. These references have focused on preparing powdered or tablet-like products that quickly dissolve and foam when placed in water. These products generally clean the denture in 12 to 30 minutes or more and require constant soaking during this period, followed by brushing and rinsing with water.

Prior art J-sulfate and perborate systems tend to discolor stains on dentures.

Nine tapes are prepared from these ingredients (tabxe
t) was limited to small amounts of detergents or surfactants because it dissolves quickly and can be cleaned when placed in water. Therefore, higher fatty alcohol type detergents could not be incorporated except in very small amounts, eg 1% or less, or the dissolution rate of the tablets was poor. The use of hypochlorite as a bleaching agent results in much more discoloration of denture stains than does the use of nosose sulfate and perborate. These chlorinating agents have the relatively significant disadvantage that they can lead to intolerable and unpleasant aftertastes and odors, and under certain conditions can adversely discolor the metal of the denture.

Furthermore, powders and tablets (tablets) in the prior art
Although the et) systems remove some denture stains, they tend to leave undissolved residues that can only be removed mechanically. Consumers usually subscribe to a regimen of soaking and brushing dentures to obtain perfectly clean dentures. Other types of undissolved residues may include, for example, chewing gum residues and denture adhesive residues. Once these residues are embedded in a denture or partial denture, they are particularly difficult to remove even with a regular brushing regimen. This obviously has a negative effect on the denture wearer. Even chewing gum that is non-stick and is specially formulated for denture wearers ends up becoming embedded in the crevices of the denture to some extent. Denture wearers generally prefer strong denture adhesives to ensure proper bonding of the denture within the oral cavity. These types of adhesives have the disadvantage that they are very difficult to remove and clean from dentures. Denture detergents cannot remove chewing gum and adhesive residues from denture surfaces because they tend to spread them rather than remove them when water is used with the detergent.

The composition of the present invention solves this problem by releasing the chewing gum and adhesive residue and then removing it by gentle rubbing with the fingers.

Most recently, a liquid denture detergent was the first South African patent application filed.
It was disclosed in the specification of No. 65146. This reference includes about 1% to about 10% by weight of a pharmaceutically acceptable surfactant, about 35% to about 70% by weight of ethanol or inpropatool or mixtures thereof, about 1% to about 10% by weight of fruit from about 25 to about 60% water and from about 0 to 5%
A foam-generating liquid composition is disclosed comprising % adjuvant. The composition should not contain more than 50% water when 42% alcohol is present, and vice versa. The surfactants disclosed are sodium lacryl sulfate, sodium dodecylbenzenesulfonate, polysorbate 80, poloxomer 407 and mixtures thereof.

The wetting agent is selected from the group consisting of glycerin, sorbitol, polyethylene glycol, propylene glycol, and mixtures thereof. The use of the trisodium salt of ethylenediaminetetraacetic acid (II) TA) in an amount of about 0.5% is also disclosed as a useful adjuvant.

Attached Figures 1 and ■ are photographs of soiled dentures. These photographs are part of the aforementioned South African Patent Application No. 165146.
The results show that the liquid spray composition for dentures of the present invention has a superior cleaning effect compared to the prior art tablet composition as well as the prior art liquid denture detergent described in the specification. is clear.

The liquid composition of the present invention is intended to be applied from a pump spray bottle. The composition does not use oxidizing agents or chlorine-containing compounds and therefore does not suffer from the disadvantages associated with these agents as in the prior art. The liquid detergent is sprayed onto the denture trap, left for about 20 to about 120 seconds, and rinsed under tap water. The length of time the detergent can be retained on the denture is dictated by the type and intensity of the soil. However, most food, tobacco and plaque stains are easily removed after about two minutes of contact with the liquid detergent. The force of the pump spray supplements the cleaning action of the detergent. The pushing force of the pump spray is set to maximize the removal of food particles and dirt on the denture surface. That is, the minimum spray force (fo
rce) is required, it provides a mechanical cleaning action without a separate brushing step. The maximum force must be kept within a range that is manageable and convenient for the user. This is determined primarily by consumer tolerance and market considerations.

More specifically, the liquid denture detergent composition of the present invention comprises: A) a sulfated fatty alcohol detergent of the formula RO803M, where R is an alkyl group of OI Q-v16 and M is Z , B) an aminocarboxylate or organophosphate plastic chelating agent, and a) from about 50 to about 98 weight percent water.

Detergents and chelating agents are used in amounts sufficient to remove dirt and plaque in the denture and eliminate malodors. Generally they are present as a mixture in an amount of about 2 to about 50%, preferably about 5 to about 30%, and most preferably about 10 to about 15% by weight of the total composition.

The weight ratio of detergent to chelating agent is from about 1:1 to about 2:1.

The use of sulfated higher fatty alcohols as detergents is well known. Surprisingly, however, such anionic detergents provide very effective denture detergents when mixed with suitable chelating agents, and when applied with power in a pump spray application, are less effective than prior art methods. Thus, a convenient and effective denture detergent is provided. Users can clean their dentures without soaking them as is required with prior art tablet and powder compositions.

It is characteristic for the invention that the sulfated fatty alcohol detergent is used in aqueous solution together with the chelating agent. These detergents, when used on their own and applied from mechanical spray devices or from aerosol mixtures, create intolerable conditions that are harmful to the respiratory tract. Uncontrollable sneezing or coughing and respiratory irritation occur. Such conditions limit its use to well ventilated and controlled areas. Quite unexpectedly according to the present invention, these detergents can be sprayed or sprayed without these harmful side effects by forming an aqueous mixture of the detergent with an aminocarboxylate or organic phosphonate chelating agent. Something was discovered. This combination reduces the respiratory and inhalation disadvantages associated with the detergents and also increases the cleaning efficacy of the composition.

The weight ratio of detergent to chelating agent described above was carefully selected to achieve these effects.

Examples of useful sulfated fatty alcohol detergents are selected from the anionic water-soluble class. Potassium, sodium and ammonium salts of higher alkylbenzene sulfonates are preferred.

Among these, linear sodium alkylbenzene sulfonate is preferred. Other examples include magnesium lauryl sulfate, potassium lauryl sulfate, sodium dodecylbenzene sulfonate, sodium lauryl sulfoacetate, sodium myristyl sulfate, sodium lauryl sulfate, sodium cetyl sulfate, sodium tridecyl sulfate, sodium salt-7-ethyl-2 -Methyl-4-undecyl sulfate. Also useful are mixtures of any or all of these detergents.

Other anionic detergents may be incorporated into the composition along with the necessary detergents mentioned above. These auxiliary detergents can be present in amounts of about 1% to about 5%. Examples of these additional detergents include, for example, the oleate ester of sodium isethionate, sodium N-cyclohexyl-N-/'!
lumitoyl taurate, sodium N-cococoacic acid-
Mention may be made of N-methyltaurate, sodium N-methyl-N-oleyltaurate and mixtures thereof. Fluorochemical surfactants, commonly known as fluor-rads, are also useful additives. For example, British Patent No. 1,322,54
Mention may be made of the compounds disclosed in No. 8, which have the following formula: where n is an integer from 3 to 10, or a glycol residue having 3 to 10 carbon atoms derived from ethylene glycol or propylene glycol as an ethoxylated alcohol with propylene oxide).

In the prior art, chelating or sequestering agents are typically denture detergents containing peroxygen bleach (
used in conjunction with (tables). The tetrasodium salt of ethyleneliaminetetraacetic acid, among others, was commonly used to sequester heavy metal impurities present in the solution and to prevent decomposition of the bleach.

Examples of useful aminocarboxylate chelating agents include, for example, tetrasodium oleate, trisodium ethylenediaminetetraacetate, diammonium ethylenediaminetetraacetate, disodium oleate, trisodium N-hydroxyethylethylenediamine triacetate hydrate, Trisodium nitrilotriacetate hydrate, hantanasodium diethylenetriamine may include trisodium nitrilotriacetate trihydrate and mixtures thereof. These chelating agents, as well as other well-known aminocarboxylates, are generally used in amounts sufficient to clean soil and Zolag when combined with detergents. A preferred amount is about 3 to about 12% by weight, more preferably about 5% by weight.
~10% by weight.

It is.

Useful organic phosphates may be selected from a wide variety of conventional materials. By way of example, mention may be made of 1-hydroxy-1,1-diphosphonic acid and its sodium, potassium and ammonium salts. These salts are also sold by Monsanto Company under the trademark Dequest. In addition to being a chelating agent, this organic phosphonate is useful as a detergent binder. These chelating agents are used in the same amounts as for the aminocarboxylates. Mixtures of any or all of these chelating agents may also be used.

The liquid denture detergent of the present invention is optionally conventionally used in the preparation of detergents to enhance cleaning and provide a brighter surface appearance of dentures. It may contain detergent virgoo which contributes to.

Examples of useful virgoos include, for example, water-soluble phosphates, pyrophosphates, orthophosphates, carbonates, and the like. Examples of useful inorganic phosphate compounds include, for example, the sodium or potassium salts of tripolyphosphate, pyrophosphate, and hexametaphosphate. Also, as mentioned above, organic phosphonate chelators are useful as virgoos. When incorporated into the composition, the binder is generally present in an amount of about 3% to about 12%, preferably about 5% to about 10%.

Other conventional additives such as flavoring agents, colorants, fragrances, antimicrobial agents, preservatives, etc. may optionally be incorporated into the compositions of the invention. For example, flavoring agents such as mint, clove oil, and artificial vanilla, to name a few, are useful. These substances can be blended in various combinations and the diet modified according to the desired taste.

As mentioned above, the liquid denture detergent composition of the present invention is intended to be applied to the denture surface from a mechanical spray device. A simple manual spray pump bottle capable of handling high viscosity fluids is sufficient. Aerosols, such as those of the piston-propelled type, are also useful, but are not preferred as they do not offer superior advantages over mechanical devices for the purposes of this invention and are more expensive. provides some mechanical cleaning force each time it strikes the denture surface.

The cleaning power can be adjusted by controlling atomization factors such as the atomization rate, the weight of the liquid applied and the rate of atomization.

To measure this force, a 1 fluid ounce propylene cylindrical pump bottle with a high viscosity spray dispensing head was loaded with the composition of the invention. The denture or other target was fixed in an Instron tensile tester. The spray bottle was mounted horizontally on the target with the spray nozzle at a distance of 1' (2,54011). An air operated piston/solenoid device was used to operate the spray pump. The air pressure to move the piston was approximately 5p81. The peak force of the spray on the target was recorded by a microprocessor connected to the output of an Instron o-cell. Measurements were in weight duram units.

These results indicated that at least 1 and preferably about 1 to 3 weight durams are required to provide sufficient mechanical action to supplement the cleaning action of the composition itself.

The weight of liquid delivered to the barrel during one actuation of the mechanical spray device was determined by subtracting the post-dosing liquid and spray bottle weight from the pre-dosing weight. The average weight given by one actuating force is about 150 to about 20,019.
Preferably it is about 160 to about 180 capes ± 25 capes. These amounts are suitable to adequately clean most dirt and plaque.

The spray pattern was measured by positioning the spray pump bottle and directing the spray nozzle onto the absorbent pad approximately 2' (53) away. The pump spray was activated once and the vertical and horizontal diameters of the spray pattern were measured as they appeared over 7 sets. The spray pattern is about 1 at a distance of about 2' from the target.
．． Preferably, the spray pattern is about 1.85'±α65 at a 2' distance from the target.
'×1.85'±cL65#teal.

The measurements were made to obtain the minimum parameters regarding the mechanical force required to achieve cleaning. Although the composition itself is a good cleaning agent, surprisingly improved cleaning of dentures occurs when the composition is sprayed with sufficient mechanical force to help remove dirt, plaque, and other debris. will be achieved.

Furthermore, consideration must be given to the choice of detergent/chelant formulation so that its viscosity is not so high that it is difficult to administer from a spray bottle. For example, when ethylenediaminetetraacetic acid tetrasodium salt is used with sodium diuryl sulfoacetate (Lanthanol LAII) or another linear alkyl sulfonate, the detergent tends to salt out, becoming a thick concentrate and difficult to spray. It makes you look different. That is, it is important that the chelating agent is water soluble and that the combination of chelating agent and detergent provides a viscosity that is easily dispensed from mechanical spray equipment. Viscosity problems and salting out effects generally occur at temperatures below room temperature and at concentrations of chelating agent greater than 5%.

To minimize these problems, agents that lower the freezing point can be added.

Examples of such agents include, for example, various glycol mixtures such as Carbowax 400 (a polyethylene glycol having a molecular weight of about 380 to 420), which contain about α5 to about 2% by weight, preferably about 0.8 Present in an amount of ~1%.

As used herein, the term "denture" refers to artificial teeth,
Includes removable orthodontic bridges, dentures, denture bases, etc.

A high degree of cleaning is generally achieved in less than 1 minute, preferably 30 seconds or less. With the aid of mechanical forces operated by the spray, the detergent strips away plaque, removes mucous substances resulting from deposits of proteins and glycoproteins,
Removes food particles and debris, removes bacteria and/or
or kill, remove residual denture adhesive and chewing gum, remove food stains, tobacco stains, and even coffee and tea stains.

Since these compositions have been shown to effectively remove chewing gum and denture adhesives, these residues can be easily removed by gentle finger rubbing or light brushing. These cleaning actions are accomplished without damaging the metal, plastic or other materials of the denture component.

The present invention allows the denture wearer to quickly clean the denture, conveniently in a portable package, without the need for a container for soaking the denture.

EXAMPLES The present invention will be explained below by way of examples, by which the invention will be better understood.

Unless otherwise specified, all amounts expressed as percentages refer to percentages by weight of the total composition.

Denture tiles were prepared with a mixture of food stains consisting of blueberries, tea and coffee, plaque.

Samples of these tiles were then selected for cleaning with one of the three compositions described above. Treatment with Composition A (invention) was done by spraying the tiles and holding the spray on each tile mold for 30 seconds, 60 seconds and 120 seconds followed by rinsing with water for 20 seconds at 45°C.

Treatment with tablets of compositions B and C (prior art) was done by dropping the tablets into a beaker of 45°C water containing tiles. Tiles treated with Composition B were soaked for 5 minutes. Tiles treated with Composition C were soaked for 12 minutes.

These results showed that the material cleaned with the composition of the present invention was significantly cleaner for 120 seconds. Tiles cleaned with Composition A were visibly cleaner than those cleaned with B and C.

Denture tiles cleaned with Inventive Composition A in the 60 second and 60 second cases required an additional spray and immediate rinse to achieve the same results as in the 120 second treatment.

Composition A was sprayed onto tiles that had accumulated plaque for 24 hours and allowed to stand for 2 minutes. Additional plaque tiles were soaked in compositions B and a for 5 and 12 minutes, respectively. All tiles were then rinsed under running water for 20 seconds at 45°C and soaked in basic 0.01% 1% Tsuksin.

Tsuksin solution is used as an indicator for plaque. The tiles were then rinsed again and compared qualitatively for red color. Tiles cleaned with Composition A (invention) had the least amount of red color resulting from horsetail and therefore had the least amount of plaque.

Example 2 This example demonstrates the cleaning efficacy of the composition of the present invention compared to a well-known commercially available tablet of the prior art and South African Patent Application No. 165146.
This figure shows a comparison between the liquid foaming detergent for dentures disclosed in the No. 1 specification and Composition O described on page 11 of the present specification.

One set of tiles (Set I) was prepared with coffee, tea, blueberry and glaze stains. Another set of tiles (Set ■) was prepared with tobacco, coffee, tea, blueberry and glaze on the plaque matrix. FIG. 1 shows the results of food-stained tiles after cleaning with each denture detergent. "Prior Art I" shown in the figure is a commercially available tablet denture detergent that was dissolved in a beaker of 45° C. water containing tiles and then allowed to stand for 12 minutes.

The "composition of the present invention" shown in the figure is Formulation A shown in Example 1. 1 in this case! The J mist was left on the tile for 120 seconds and rinsed with water for 20 seconds at 45°C.
