Definitions

  • This invention relates to the use of disodium octaborate tetrahydrate (D.O.T.) as the sole ingredient, or as an active component of a bath salt primarily intended for use in a bath for one or a small number of individuals .
  • D.O.T. disodium octaborate tetrahydrate
  • Borates are oxides of the element Boron.
  • the borate to be used in the invention is refined from a naturally occurring ore found in the hot, dry climate of the Mojave Desert of Southern California.
  • the natural origin of the material combined with its comprehensively defined toxicological characteristics gives a material which is safe in the intended use and which exhibits properties required of a functional bath salt.
  • boric acid and borax are well documented prior art.
  • the bacteriostatic and fungicidal properties of borates general benefit in wound healing.
  • Boracic or boric lint has been in continuous use from 1875 to the present day.
  • Borax and boric acid are used in cosmetics such as creams and with other ingredients such as powders .
  • the present invention provides the use of disodium octaborate tetrahydrate as, either totally, or substantially, or in part, a bath salt, with such a bath salt exhibiting many advantages over existing bath salts and other forms of borate.
  • the invention thus provides a bath salt consisting of, or comprising disodium octaborate tetrahydrate as an active ingredient thereof.
  • the bath salt of the present invention may further comprise any of the group comprising surfactants, oils and herbal extracts. These are believed to extend the bacteriostatic qualities of borates. Such formulations are been designed to create a pleasant smell, to enhance other qualities such as cleansing or to suit particular skin types. For example dry skin in particular is known to benefit from the emollient properties of some oils.
  • Bathing generally consists of an individual being immersed in preferably hot water for a reasonable period of time. Although this water is at a temperature that makes it comfortable to bathe in, it has the disadvantage of providing a suitable environment for the multiplication of many forms of bacteria and other microorganisms and fungi of medical importance. The occurrence and propagation of such microorganisms in said bathing medium constitutes a health risk. In such instances, the present invention has particular advantages for the bather by means of reducing the propagation of such microorganisms in the bathing medium. This is due to the bacteriostatic properties of disodium octaborate tetrahydrate. In bath salt formulations where additional ingredients are added to the DOT, these may also exhibit bacteriostatic properties, though these ingredients would not necessarily be selected for such properties.
  • the present invention provides the use of DOT to prevent the build-up of bacteria and fungi in bathing environments.
  • the invention also provides the use of disodium octaborate tetrahydrate to provide water softening characteristics and or wound healing characteristics m a bath salt.
  • a bath salt comprising or consisting of disodium octaborate tetrahydrate.
  • this bath salt preparation would be dissolved into the bathing water prior to the commencement of bathing.
  • the bath salts are used m circumstances where the bathing will be done m water of a hot or warm temperature (typically between 5 and 40°C) .
  • disodium octaborate tetrahydrate preparation is formulated in combination with other adjuvants and surfactants.
  • the bath salt preparation has suitable characteristics. It will dissolve into a solution with the bathing medium. Essentially, the bath salt shall exert no harmful effect on either the bather or the bath.
  • the bath salt preparation containing disodium octaborate tetrahydrate is incorporated into the bather's medium for beneficial effects.
  • Figure 1 illustrates the IC 50 values of three tested compounds in standard aqueous buffer solution (lOmM phosphate, pH 7.2) at 25°C.
  • Figure 2 illustrates a comparison of toxicities of the three compounds calculated on a weight basis.
  • the Microtox assay utilises ViJbrio fischeri , a Gram-negative, luminescent marine bacterium, which belongs to the same family of organisms as Escherichia coli ( E. coli ) .
  • the principle of assay is that bioluminescent light output, from the bacterium requires cellular respiration and accordingly the expenditure of metabolic activity.
  • bioluminescent light output from the bacterium requires cellular respiration and accordingly the expenditure of metabolic activity.
  • metabolising cells give high levels of bioluminescent light output, while dead or otherwise metabolically inactive cells limit no light.
  • the light output from a culture in aqueous suspension, as measured using a luminometer is a direct measure of the health of that culture.
  • the toxicity of a compound can be measured by this assay thus determining the toxic characteristics of the component and whether it will effect the cellular respiration of the bacteria which in turn will lead to a decline in the overall bio-luminescence emitted from the culture.
  • the rate of decay of light output from a bacterial culture following the addition of a putative toxic compound ('toxicant') can be straightforwardly translated into an IC 50 valve the IC 50 concentration of a toxicant required to reduce the bioluminescent light output of a v. fischeri culture by fifty percent.
  • An LC 50 valve is determined in a 1 hour test; while for an IC 50 valve, the concentration required to reduce the numbers of bacteria by 50%, is determined in a 30 minute test.
  • HBP 2- hydroxybiphenyl
  • bath salts can be formulated which deliver borates to a final concentration in the range 100 - 1000 mg/1 (0.1 - lg/1) .
  • concentration given in the results at which toxicity against the bacteria is shown is perfectly workable. A lower concentration may have no, or a reduced effect.
  • Table 1 Solubility of DOT and borax at varying temperatures .
  • the alkalinity is an important characteristic of a bath salt .
  • a remarkable attribute of borates in general and disodium octaborate tetrahydrate in particular is the fairly constant pH for a wide range of concentrations at a given temperature.
  • Aqueous solutions of disodium octaborate tetrahydrate range from mildly alkaline at low concentrations to practically neutral as the concentration increases at ordinary temperatures. This property is particularly relevant to the intended application as a bath salt.
  • Table 2 exemplifies the above points by comparing the percentage of disodium octaborate tetrahydrate by weight of solution to its respective pH at 23°C.
  • Table 2 Comparison of the percentage of disodium octaborate tetrahydrate (DOT) by weight of solution to its respective pH at 23°C.
  • DOT disodium octaborate tetrahydrate
  • DOT may be formulated with many adjuvants, surfactants etc. It is envisaged that it would be preferable for all formulations to be placed in the bath, in the vicinity of the hot tap where they would be dissolved into the bathing water by means of the turbulent flow created by the hot water entering the bathing vessel, until a saturated solution is achieved.
  • this bath salt preparation would be dissolved into the bathing water prior to the commencement of bathing.
  • the invention is inclusive of all forms of disodium octaborate tetrahydrate which can be presented as a fine powder or as large granules or alternatively in liquid form in solution.
  • the invention would be placed under the hot water tap in sufficient quantity to approach saturation for any chosen temperature. Some individuals may prefer to use a lower quantity of said DOT than others.
  • disodium octaborate tetrahydrate in granular form, incorporating all herbal extracts and surfactants could be supplied in a one-use, one-bath sized "Tea Bag” style bag device .
  • the bag could be suspended by means of string in the hot water stream entering the bath from the tap or placed directly in the bath.
  • the bag may be made of linen or similar fabric or of man made fibres of slightly course texture, which could be used to rub and gently cleanse the skin. This would have the effect of removing dead skin cells, thus helping to remove bacteria and generally exfoliating and invigorating the skin.
  • the cloth could also be used to clean the surface of the bath after use, before being disposed of.
  • Borates have proven bacteriostatic properties and can help to control those bacteria responsible for skin conditions including Staphylococci and Streptococci.
  • herbal extracts and surfactants are selected to enhance bacteriostatic properties.
  • Protozoa In areas where inadequate treatment of the water supply is common, it has been reported that Protozoal diarrhoea can be contracted from showering and bathing. Examples are known in St Louis in the former Soviet Union. Residents in or visitors to such areas of risk could gain protection by the use of the invention.
  • - Fungicidal For some forms of fungi borates are the most effective form of control available. Disodium octaborate tetrahydrate has been shown to be effective where boric acid has no effect, due to its greatly increased solubility in aqueous solution.
  • Fungi that the invention will help to control include Candida albi cans , a normal comensural of the human gut, which can colonise pre-existing dermatitis, all dermatophyte infections (forms of tinea such as dandruff and athletes foot) and the yeast causative organisms of Pityriasis versicor.
  • An application to which the present invention may be of particular relevance is to women who have just given birth. Following childbirth, there is a need for the mother to have a sterile bath. This is especially required when surgery or damage has occurred as part of the childbirth process. In such instances, the present invention would be of particular benefit due to the provision of sterile conditions and the promotion of wound healing and regeneration of skin cells which is facilitated by the borate esters.
  • bathing in bath salts of disodium octaborate tetrahydrate is not universally acceptable.
  • human infants can readily absorb many chemicals.
  • infants should not bathe in bath salts.
  • elderly This also applies to people with serious or extensive skin conditions.
  • individuals if concerned should seek the advice of a dermatologist, or similar medical advice.
  • This invention is not intended for use in public facilities where there is a risk of transmission of serious disease from one person to another. Where these risks have been overcome by use of an effective non-chemical treatment system (possibly ultra violet) then it may be safe to use the invention.
  • an effective non-chemical treatment system possibly ultra violet
