Abstract
Abstract:
The invention is a body dusting powder for external use, containing a live yet dormant bacterial culture which may consist of various strains of bacteria knownto inhabit the intestinal tract of the human body, particularly strains of lactobacillus and bifidus, and including especially, lactobacillus acidophilus and bifidobacterium, and also including a suitable growth medium for same.
When the invention is applied to external areas of the human body such as feet, hands, underarms, scalp, rectal and genital areas, for example, bacterial cultures contained in the powder are revived in the presence of moisture due to perspiration, and the cultures grow and multiply, feeding on the growth medium provided, producing lactic acid and other antibiotic substances, thereby inhibiting other micro-organisms normally found growing in these areas, as well as those found in the air which may alight upon these areas.
When applied to the human or animal body, the invention prevents and controls the growth of undesirable organisms such as cornybacterium, propionibacterium acnes, diptheroid bacteria in general, staphylococci, streptocooci, coliforms, and fungae and yeast such as candida or tinea pedis.
The invention inhibits the spread of sexually transmitted and contagious diseases which may be due to organisms which enter the skin and the body from the air, which might otherwise be transmitted through body to body contact.

Description
Disclosure The invention relates to a body dusting powder, useful for the prevention and control of micro-organisms normally present or found growing on external surfaces of human and animal bodies.
The invention prevents and controls infectuous and sexually transmitted diseaseswhich might otherwise be transmitted through body to body contact.
Similarly to other dusting powders, the invention helps keep external areas of the body smooth and dry by absorbing moisture due to perspiration.
It is a common practise to apply dusting powders to external areas of the human body, in order to absorb perspiration from these areas and to thereby reduce undesirable odours produced by micro-organisms inhabiting these areas, which act on sebacious secretions. In some instances, dusting powders are applied to relieve itching and rashes due to the bite of insects such as fleas. For such purposes, most commonly used dusting powders consist of finely divided mineral powders such as talc, otherwise known as talcum powder, which is predominantly magnesium silicate containing lesser amounts of calcium, iron, and aluminium oxides. In some instances, such commonly used powders also contain added fragrances and may also contain oils or other substances which are known to possess anti-bacterial or anti~fungal properties.
The manner of action and the purpose of most commonly used dusting powders is primarily to absorb moisture from the skin, so that the growth of micro-organisms which would otherwise proliferate in the presence of such moisture is prevented.Such organisms include the following species: Cornyebacterium or propionibacterium acnes, diptheroid bacteria, staphylococci, streptococci, coliforms, candida, pitylosporon, and tinea, to name but a few examples. Dusting powders are also employed to absorb substances produced by micro-organisms inhabiting the skin, which substances maybe the cause of obectionable odours...such as propionic acid, to name but one example of an offensive substance.
6'7 Where commonly used dusting powders contain added fragrances, such fragrances serve to disguise an objectionable odour which might otherwise be produced by a micro-organism acting on a sebacious secretion. Where a commonly used dusting powder contains an added substance which exhibits anti-bacterial or anti-fungal activity, such substance helps prevent the growth of micro-organisms on external areas of the body or causes their elimination from these areas. No prior art dusting powder contains a bacterial culture which is added.
The inventive idea which the dusting powder of this invention embodies is that in addition to the use of talcum powder, fragrances, and anti-microbial agents which might be included in a commonly used powder, there is also added to the powder, a bacterial culture and a growth medium for same. Such added culture is selected from amongst various strains of bacteria known to inhabit the gastro-intestinal tractof the human body, and are preferrably of the species lactobacillus or bifidobacterium, but are most preferrably lactobacillus acidophilus and/or bacterium bifidus.
The growth medium added to said dusting powder is any suitable mixture of substances known to favour the growth of bacterial cultures which are added, such as for example, bactooxygall bile, but is most preferrably a conveniently employed form of dairyproduct, such as powdered milk, whey, or cheese solids, or some other product derived from a dairy source.
The intuitive aspects of the invention are as follows......
As lactobacilli and bifidobacterium are found naturally inhabiting internal regions of the human body, these may be considered as organisms beneficial and necessary for proper growth and maintenance of the human body. An optimum balance between lactobacilli, bifidobacterium, and other organisms of the intestinal tract is associated with good health and nutrition, and in vitro inhibitory activity of these organisms against intestinal pathogens is reported. L. acidophilus and Bifido-bacterium have been reported to inhibit the following species of pathogenic and especially gram-negative organisms....Salmonellae, Shigellae, Staphyloco~ci, Proteus, Klebsiella, Pseudomonads, E. Coli, Clostridium, Perfringens, and Vibrio, to name but severalexamples. Inhibition of these organisms is attributed to the production of organic acids acetic and ëspecially lactic, and to anti-biotic substances produced by acidophilus or bifidobacterium, and also to competition between lactobaccili andbifidobacteria and these pathogenic organisms, for nutrients and growth sites inthe intestine. Thus, presence of lactobacilli and bifidobacteria in the intestinal ..3 i 6 ~
tract prevents the resurgence of harmful organisms which might otherwise proliferate in these regions.
In view of the beneficial aspects of lactobacilli and bifidobacterium, as applies to their presence in the gastro-intestinal tract of the human body, it seems logical to assume that if these species were present in or upon external areas of the body, that they would exhibit inhibitory activity against other micro-organisms found in these areas as well, due to the preceding factors, and if permitted to grow in these areas by the presence of proper nutrients and growth factors.
However, such species of bacteria are not normally foun~ growing in these areas,presumably because of the absence of suitable growth factors. Furthermore, since these species are not found on external areas of the human body, it is also logical to assume that proper growth factors do not exist in these areas, and that therefore, if substances necessary for proper growth were to be added to these areas or to be made available, then the growth of lactobacilli and bifido~acter;um would be promotedin these external areas. Conversely, organisms which grow naturally on external surfaces of the human body such as those previously described, are not normally found growing in intestinal regions, presumably for similar reasons given above, and obviously prefer the skin and its' sebacious secretions as a natural habitat.
Now, since lactobacilli and bifidobacterium are infectuous to certain other micro-organisms, and since they are found to grow exceptionally well in dairy products tuch as liquid milk for example, presumably utilizing lactose as a preferred carbohydrate for their metabolism, it is logical to assume that if these species were applied to external areas of the human body together with and in the presence of substances derived from dairy products such as milk, which also contains lactose, and also given that in the presence of sufficient moisture, these species would proliferate and compete with other micro-organisms of the afore-mentioned types found growing naturally on the skin, and would survive to become dominant members of the population of all types.
The newly introduced species would grow on the dairy substances provided, and perhaps also on perspiration exuded by the body, thereby producing acetic and lactic acids, and also producing antibiotic substances, thereby lowering the pH of the skin, and thereby inhibiting or perhaps even eliminating other resident species known to be responsible for various skin disorders and for various infectuous or sexually transmitted diseases as well.
- 4 - 2~ 7 Furthermore, the newly added species are not toxic to the human body, and do not produce substances which are toxic, since these bacteria and the substances they produce are normally found in the intestinal tract. The bacteria do not give rise to obnoxious odours as by-products of their own metabolism, the chief of these by-products being lactic acid, which is normally present on the skin, as one of the breakdown products of other micro-organisms acting on sebacious secretions.
In addition, the newly added species can possibly utili~e natural sebacious secretions, as well as dairy substances provided as a medium for growth, thus helping to eliminate natural secretions of the body which might be toxic in themselves.
Thus, it is conjectured that the application of beneficial organisms of the intestinal tract, such as lactobacillus or bifidus, to external àreas of the human body such as feet, hands, scalp, genital and rectal areas, in the form of a dusting powder in which they are contained, would have a beneficial effect for the human organism. Harmful bacteria and fungae such as Tinea would be inhibited, substances toxic to the body would not be produced by these organisms, and perspiration would not be exceedingly odourific.
Therefore, it is an objective of this invention to provide a formula for a dusting powder, as well as a methQd of making said dusting powder, which formula and method differ from prior art processes in that the dusting powder of this invention contains a bacterial culture or an organism found growing naturally in the humangastro-intestinal tract, which organism is preferrably selected from the specieslactobacillus or bifidobacterium, and in that the formula also contains a dairy product as a suitable medium for growth of the added culture; and also in that the method of preparation of said dusting powder differs from that of prior art processes.
It is a further object of this invention, to provide a dusting powder which relieves the itch and sting of insect bites such as fleas for example, as well as the itch and sting produced by bacterial or fungal infections of the skin.

.
2 ~ 7 It is a further object of this invention to provide a dusting powder which inhibits the transmittance of contagious and sexual diseases, due to various micro-organisms found naturally on the skin.
Finally, it is an object of this in~ention, to provide a dusting powder which similarly to other commonly used dusting powders, helps keep the skin smooth, supple, and dry, and will absorb or disguise obnoxious odours by virtue of the fact that it contains an added fragrance.
The manner in which the product of this invention may be prepared is as follows:
.
In order to prepare a dusting powder having characteristics of the preced~ng description, there is added to a finely divided mineral powder such as talc for example, the following ingredients: A dairy product in powdered form, such as dried milk solids, whey solids, or cheese solids, a purified and dried bacterial culture such as lactobacillus acidophilus or bifidobacterium; and a fragrance which may be an oil.
!
The mineral powder is preferrably talcum powder, and may range in content from 75 - 95% by weight of the formula, but is preferrably 90-95% by weight of the formula.
The dairy product is preferrably a spray-dried milk powder such as full fat milksolids, de-fatted milk solids, buttermilk solids, whey solids, lactose, dehydrated full fat or de-fatted cheese solids, but may also be in the form of a liquid product such as whole milk, 2% milk, 1% milk, skim milk, buttermilk, lactose-free milk, milk to which an acidophilus or bifidobacterial culture has been added. The content of dairy product in the powder may range from 1 - 20% by weight but is most preferrably 4-5%
by weight.
The bacterial culture to be added may be chosen from a strain of lactobacillus or bifidus, but is preferrably a strain of of acidophilus or B. Bifidus, or a mixture of both, for example, in such ratio as might be found in the gastro-intestinal tract. In the case where the dusting powder is to be used to benefit an animal, strains of bacterial culture added to the powder are preferrably selected from a type of lactobacillus or bifidus found growing naturally in the intestinal tract of the particular.animal for whom use of the product is intended. The content of bacterial culture in the powder may range from ~ - 10% by weight of the powder, but is preferrably between 1 and 2~ by weight. Preferrably, the bacterial culture is added to the dusting powder in the form of a freeze-dried powder.
The type and quantity of fragrance to be added is predicated on the degree of masking of body odour required, or purely according to aestheticism.
The manner of preparation of the product of this invention is to simply mix all ingredients in appropriate proportions as precedingly described, but is most preferrably firstly, to disperse the fragrance, especially where an oil, throughout the talcum powder, by means of spraying the fragrance onto the powder using a suitable device, while simultaneously mixing the powder in order to provide dispersionj and, secondly, adding the freeze-dried bacterial culture to the ¢air~ solids while mixing gently until uniformly dispersed; and finally, by adding the dairy solids mixture containing the added bacterial culture, to the talcum powder containing the added fragrance, and mixing well in order to prepare the dusting powder which is the product of this invention.
In the case where the dairy product or the bacterial culture is added to the powder in the form of a liquid preparation, the liquid is preferrably sprayed onto the talcum powder, and the powder is dried under gentle conditions at low temperatures before adding remaining ingredients to the formula. For example, the talcum powder may be sprayed with liquid milk, and then dried, before the remaining ingredients are added...or, the talcum powder may be sprayed with liquid milk containing an L. acidophilus culture, or a B.Bifidus culture, and then dried gently before thefragrance is added.
The product of this invention may be prepared using any suitable mixing equipment known to the prior art, such as a typical household mixer, but the mixing actionshould be as gentle as possible in order to avoid damaging the added bacterial culture by fracture or bruising for example; therefore, mixing of the powder should be kept to a minimum whenever the bacterial culture has been added.
....7 According to the preceding, a preferredformula for the invention is the following:
Talcum Powder 95% by weight, or 95 grams/100 grams formula Whey Protein Concentrate (containing 35-37% protein by weight) 4% by weight, or 4 grams/100 grams formula Freeze-dried L. Acidophilus culture (containing 10 million cells per gram) ~2% by weight, or ~2 gram/lOOgrams formula Freeze-dried B. Bifidus culture, (containing 10 million cells per gram) ~2% by weight, or ~2 gram/100 grams formula Fragrance or Perfume 5 drops, or 0.25 ml/100 grams formula According to the disclosure, it can be seen that the dusting powder of this invention differs from those of prior art dusting powders in both formulation and in method of preparation.
The manner of application of the dusting powder of this invention is similar to that of prior art dusting powders; wherein the powder is simply applied to those areas of the body as desired, which areas may include feet, ankles, knees, underarms, scalp. or rectal and genital areas. The powder is then spread over the area by use of the hands, therefore? the hands need not be described as an area of application, as they are naturally coated according to the manner of application.
The effectiveness of the invention may be realized in the following manner:
Once applied, the powder immediatedly absorbs perspiration and moisture from the skin, and the bacterial cultures which are present can be revived and begin to multiply in the presence of such moisture, thereby inhibiting the growth of other micro-organisms inhabiting the area to which the powder is applied.
If the dusting powder has been removed from the skin for example by frictional contact with clothing or other objects, by gravity free fall from the skin, or by washing or bathing, then the added bacterial cultures having had a chance to establish themselves ....8 2 Q ~ 7 by attachment to sites within the skin layers can still be effective against other bacteria and fungae, by either feeding on residual dairy product which has not been removed from the skin in the preceding manner, or by feeding on perspiration secreted by the body. The established cultures then produce substances toxic to other micro-organisms, or inhibit other micro-organisms by becoming dominant members of the population of all species present.
