Description

DEODORISING PREPARATION PRODUCED FROM NATURAL INGREDIENTS AND THE PROCESS BY WHICH IT IS PRODUCED

The present invention pertains to a deodorising preparation produced from natural ingredients and the process by which it is produced which consists overwhelmingly of coconut oil and its exclusively natural derivatives produced by the treatment thereof, along with minute amounts of sodium bicarbonate, edible emulsifier, and vitamin E, with the possible addition of a scented material of natural origin such as adds to the useful value of the product.

The invention is recommended for any user group, but, due to the natural components that render it basically edible, could be used by those who are sensitive to conventional industrially produced cosmetics, those who suffer from skin diseases, and even children.

Preparations containing coconut oil have been on the market for a long time. Given the high lauric acid content of the oil, these products are specially recommended and used for not only cosmetic, but also expressly dermatological purposes. In the discussion to follow, we introduce the two solutions representing prior art that fall closest to the topic of this invention. Patent specification US20060269507 discusses an ointment consisting of beeswax, cocoa butter, virgin coconut oil, shea oil, virgin olive oil, lavender oil, and tincture of benzoin. The specification provides a ratio of ingredients expressed in percent mass and volumetric quantities (7-17% beeswax, 21-29%) cocoa butter, 21-29% virgin coconut oil, 21-29% shea butter, 11.5-21.5% virgin olive oil, 0.1-20 ml lavender oil, 0.1-20 ml tincture of benzoin), and on this basis, offers several specific recipes. As regards the topic of use, the beneficial effect of the preparation as used for various skin ailments (e.g. eczema, chemical burns) is supported by means of examples.

The preparation itself differs significantly from the one presented herein in terms of both ingredients and sphere of use. For one thing, it can be seen on the basis of the percent composition that coconut oil is not the overwhelmingly primary ingredient as it is in our solution. Furthermore, the ointment contains neither liquid (fractionated) coconut oil, nor sodium bicarbonate. The objective of the invention is not to use and to improve upon the beneficial properties of coconut oil for cosmetic purposes, but to produce an ointment from several components suitable for the treatment of skin diseases.

Patent specification US 20080199544 describes a use of liquid (fractionated) coconut oil for dermatological purposes. The invention is actually the discovery of this use: that said oil is effective in preventing and treating skin disorders (including dry skin, eczema, non-atopic dermatitis). The specification does not mention other additives, nor does it note any cosmetic use or related functional requirements.

As regards our examination of the above and other solutions not mentioned in this description that are only slightly similar to this invention, it may be established that no cosmetic preparation featuring a mix overwhelmingly composed of fractionated and virgin coconut oil that contains only natural ingredients is currently known or patented, nor did any of the inventions we examined target the properties and attributes we have as objectives.

The inventions that represent current prior art, along with those that typify the cosmetics industry's current offerings for the problems of perspiration and unpleasant body odour are all generally characterised in that they operate with ingredients that carry serious health risks. Of these, the most significant are - but are not limited to - the following: Ingredient Use, demonstrated side effects / risks

aluminium anti-perspirant; carcinogenic

parabens Antifungal and antibacterial, used as preservatives;

carcinogenic, upsets female hormonal balance and may therefore lead to organ dysfunction and birth defects

propylene glycol solvent and humectant; may damage the central nervous system, liver, and heart

phthalates Can disturb hormonal balance, decrease testosterone levels, cause birth defects, European Union regulations restrict their use

triclosan Antibacterial and antifungal organic substance; long-term use can cause cancer and may negatively affect thyroid function

Butylated hydroxytoluene preservative; may cause developmental disorders, allergies, and/or biochemical and cellular changes; may disturb endocrine function

Other chemical substances can also cause users or those in the user's environment unpleasant dermatological or respiratory reactions, such as various forms of skin irritation, sneezing, allergic symptoms.

But it is not only the adverse effects described above that render the task of inhibiting perspiration and disinfecting the skin via the artificial chemical substances used by the cosmetics industry problematic. Where such a method is used, toxins that the body is attempting to get rid of are forced into the lymphatic glands, which itself can cause serious conditions, from simple inflammation to tumorous diseases. The risk is lower with men because most of them apply anti-perspirant deodorants to the hair under their arms, thus creating a smaller blockage against perspiration than that experienced by women who shave their armpits. The body needs to rid itself of toxic substances through mechanisms such as perspiration. When a body sweats, it releases not only moisture, but also various other secretions that, upon reaching the surface of the body, serve as food for the bacteria that live there. It is during the process by which these bacteria break down sweat that the compounds largely responsible for unpleasant body odours are created.

With this invention, our objective was to create a cosmetic substance - specifically, a deodorant preparation - that has all of the following properties:

- absorbs perspiration,

- kills bacteria and fungi,

- hydrates the skin,

does not cause irritation,

- is pH-neutral to the skin,

- is composed only of natural substances,

- is produced without the application of chemical processes,

- because of its natural ingredients, is technically edible,

- preserves its quality for a relatively long period of time,

gives its user a natural scent,

remains a liquid both at room temperature, and within as wide a range of temperatures close to room temperature as possible.

Given the above problems and factual information, we came to realise that the solution according to our invention could not rely primarily on stopping perspiration as a method, but that we must meet our stated objectives by avoiding the above-described cosmetic industry solutions, selecting a natural method and ingredients, and combining them in an effective manner.

In our view, a cosmetic product can only represent high quality if it performs its designated function with only minimal health risks, the best guarantee for which is to build on traditionally applied, natural substances with well-known effects, chemically treated only to the extent that is absolutely necessary. At the same time, it must be noted that there have been exclusively organic products, created with this philosophy in mind, on the market for some time now. Most, however, including those described in the section above on prior art, include a large number of ingredients, which makes them difficult and expensive to manufacture, and in less fortunate cases, achieve the targeted effect only in reduced measure due to the "dilution" of their active ingredients.

We have furthermore recognised that we can meet our objectives best by using only one base substance, originating from a natural source, that has not been modified via industrial processes; thus, our invention builds overwhelmingly on this one substance and its various forms, and as regards active ingredients, aims to achieve the highest possible percent content of this one substance, once all circumstances have been taken into account.

Thus, for this invention, we have selected coconut oil as our base ingredient, as when used appropriately, it meets the largest number of the requirements listed above:

Coconut oil is produced from coconuts. A ripe coconut is a hard-shelled fruit covered in tough, fibrous threads that weighs 1-2 kg and has a diameter of about 25-30 cm. Every part of the coconut can be used for something, whether for industrial, dietary, or cosmetic purposes. When freshly pressed, coconut oil is white and has a characteristically pleasant scent. It is rich in the roughage, vitamins, and minerals required by the human body.

In practice coconut oil can take any one of four forms: a) Cold-pressed coconut oil

A clean, transparent liquid which, because of the lack of heat treatment, displays all the positive properties and contains all the beneficial components for which the oil is known. b) Virgin coconut oil

A mechanically produced oil that has not undergone the RDB process (has not been refined, bleached, and deodorised), nor been hydrogenated and that congeals at temperatures below 24°C. The percent content of long-chain lauric acid, the substance that is largely responsible for the oil's antibacterial, andtifungal, and immunoenhancing properties, is typically above 47% in extra virgin and cold-pressed coconut oil, but is reduced to around 1 1% in the fractionated variety. As the concentration of lauric acid in mother's milk, a natural source for humans, falls between just 6% and 10%, the subject of this patent will be able protect - and even enhance - the immune system to a very substantial degree. c) Refined coconut oil

Coconut oil that has undergone RBD processing (has been refined, bleached, and deodorised). Refined coconut oil is transparent or yellowish in colour, has a neutral taste and odour, congeals at temperatures below 24°C, and is excellent for cooking and frying. In the course of refinement, however, it loses its valuable vitamin and amino acid content and is therefore of less value to the human body. Because it is hydrogenated, it remains stable even at higher temperatures and food cooked in it keeps longer; however, when used by the human body, small amounts of damaging trans fats are generated. d) Fractionated coconut oil

Oil extracted through fractional vacuum distillation, consisting largely of triglycerides with a reduced proportion of long-chain molecules. Fractionated coconut oil is colourless liquid with a neutral taste and odour that congeals at 3°C.

In the section to follow, we discuss the beneficial properties of coconut oil for which it has been selected as the principal ingredient of our invention:

C) Anti-bacterial and anti-fungal properties, dermatologically pH-neutral

The dermatological benefits of cold-pressed coconut oil have been known in Southeast Asia and the islands of the Pacific Ocean for millennia:

- The oil has antifungal, antibacterial, and antiseptic properties and as a result, serves as a treatment against both inflammation and dry skin.

- It is rich in polyphenols and therefore prevents the generation of free radicals and slows aging of the skin

- It hydrates the skin and increases its resilience

- It softens and sooths the skin, while providing nutrients to the epidermis

- It helps the skin maintain its natural pH

- It helps reduce the damaging effects of sunlight on the skin The properties of virgin coconut oil are fundamentally identical to those of cold-pressed oil, while all other forms exhibit the above properties to reduced degrees, depending on exact chemical composition. The percent content of long-chain lauric acid, the substance that is largely responsible for the oil's antibacterial, antifungal, and immunoenhancing properties, is typically above 47% in extra virgin and cold-pressed coconut oil, but is reduced to around 11% in the fractionated variety. As the concentration of lauric acid in mother's milk, a natural source for humans, falls between just 6% and 10%, the subject of this patent will be able protect - and even enhance - the immune system to a very substantial degree.

We have also recognised that as the high lauric acid content raises the point where extra virgin and cold-pressed coconut oils congeal to around 24 degrees C, it is unsuited to cosmetic purposes unless an organic solvent or - where this is not available - a water- containing liquid and an emulsifier are added. As we did not wish to compromise with respect to our above-stated objectives, we sought a solution where the product remains in a liquid state for the largest possible domain of temperatures, as correspond with its field of use, by mixing coconut oil derivatives in the appropriate proportions.

In stating our claims below, the percent ranges for various components of coconut oil were determined by experiment with the following circumstances taken into account: a) After purchase, cosmetic products are generally kept in the bathroom, which, depending on the personal habits of the consumer, is heated either continuously, or only when in use. Since bathrooms are connected in some way to the other rooms of the house, it can be reasonably assumed that the temperature will not fall below a certain level. Our first point of reference was taken to be 8 degrees, as the temperature in the vast majority of households will never fall below this level. In order to ensure that our invention should congeal at 8 degrees, the coconut oil mixture must be 59 m/m % virgin and 39 m/m % fractionated oil. b) As we consider it conceivable that a product corresponding to our invention might also be distributed to places further south of Hungary and closer to the equator, where the levels of cold typical of the European continent do not arise even in winter, our second reference point was set at 18 degrees. In this case, the mixture should be made from 80 m/m % virgin and 17 m m % fractionated coconut oil. In defining the composition of the coconut oils used in producing this invention, we departed from international test results and calculations conducted in the course of our own experiments. For fractionated and virgin coconut oils mixed in the appropriate proportions, individual saturated fatty acid concentrations vary according to the following table:

According to folk wisdom, household baking soda (sodium bicarbonate) can be rubbed under the arms as an easy, inexpensive way to prevent perspiration. The belief does, in fact, have scientific merit, as baking soda is highly absorbent and in solution is alkaline, so that it exerts a destructive effect on fungi and bacteria that live on the skin and are adapted to its acidic pH. Most anti-perspirant cosmetics already contain a significant amount of baking soda (typically 20-30%) for both the reasons state above, and because it represents an expedient and - not unimportantly - inexpensive solution to the problem of dermatologically neutralising the organic acids they contain. It is also important to remember, however, that the excessive use of this material can dry the skin and cause irritation. In order to avoid undesirable side- effects, our invention is prepared using only the most necessary amount of sodium bicarbonate, and this was certainly possible, given that the pH of coconut oil does not justify the addition of an excessive amount of alkaline material.

As regards the rest of the components of the preparation, scientific research has shown no probability of skin irritation as a side effect.

Another indicator of the naturalness of this invention is that, while we intend it primarily for cosmetic use, we have formulated it to be edible, as well. In fact, what the digestive system, which is especially sensitive to damaging chemical substances, can process, cannot possibly be damaging to the skin and epidermis, which are defined as the body's first line of defence and are resistant to much harsher chemical and biological hazards. Since coconut oil is - based on millennia of experience - perfectly edible, while baking soda is used primarily in household food preparation and as a home remedy for heartburn, all that was left was to select an appropriate emulsifier to be used in combining the two. A further objective was to thicken and gelatinise the product (to aid in absorption) without changing the point at which it congeals. Thus, we selected Dermofeel Viscolid, as it was found to be the only substance on the market that has been irrefutably demonstrated to be both edible and free of side effects.

Both oils and fats - with particular reference to triglycerides with their unsaturated fatty acids - grow rancid when exposed to oxygen in the air. In the process, fatty acids, hydrocarbons, keytones, aldehydes, epoxides, and alcohols are produced, which give the initial substances/mixtures a sharp taste and unpleasant odour. To avoid this problem and to increase shelf life, antioxidants are added to oils and fats. Since for our invention, we require that the product be edible, of various antioxidant groups in general use, we chose that of E vitamins, which are most natural for the human body. Sixteen years of experience and research with Tocobiol, manufactured by BTSA, reveal it to be one of the best available agents in preventing rancidity. The product is 100% natural in origin, its general use in the grocery industry serving as a guarantee of it edibility.

Our invention would fulfil all its target functions even if it contained only the ingredients listed above. However, for reasons of both the market and the product's use as a cosmetic, it was decided that scents might also be added in order to make it more attractive. In selecting these substances, again, care was taken that they should be both natural and edible. Thus, lavender and tea tree oils were chosen as solutions that would meet every requirement.

Thus, the subject matter of this invention is a deodorising preparation produced from natural ingredients that consists of 100% natural substances, has anti -bacterial and anti-fungal properties, is dermatologically pH-neutral, and contains coconut oil.

The preparation is characterised in that it is liquid above a minimum temperature of 8 degrees C, but preferably above 12 degrees C, is edible, and consists of at least 97 m/m% coconut oil, of which 17-59 mm/m% is fractionated and 39-80 m/m% is virgin coconut oil; 1-5 m/m% edible emulsifier; 0.5-1.5 m/m% edible vitamin E; 0.05-0.15 m/m% refined, edible sodium bicarbonate; and 0.05-0.15 m/m% optionally added, natural, edible scent.

In one preferred mode of carrying out the deodorising preparation according to this invention, the lauric acid content is preferably 25-40 m/m%.

In another preferred mode of carrying out the deodorising preparation according to this invention, the edible vitamin E is preferably Tocobiol.

In a third preferred mode of carrying out the deodorising preparation according to this invention, the edible emulsifier is preferably Dermofeel Viscolid.

In a fourth preferred mode of carrying out the deodorising preparation according to this invention, the edible, natural scent is lavender and/or tea tree oil.

The composition of the preparation according to this invention is described below via two examples, to which the scope of patent protection shall not be limited: 1. Composition of product for sale on the continent:

Fractionated coconut oil: 58.196 m/m %

Virgin coconut oil: 38.797 m/m %

Refined sodium bicarbonate: 0.970 m/m %

Dermofeel Viscolid: 1.940 m/m %

Tocobiol: 0.097 m/m%

2. Composition of product for sale in tropical areas:

Fractionated coconut oil: 16.993 m/m %

Virgin coconut oil: 80.000 m/m %

Refined sodium bicarbonate: 0.970 m/m %

Dermofeel Viscolid: 1.940 m/m %

Tocobiol: 0.097 m/m%

The subject matter of this invention additionally extends to the process by which the deodorising preparation of natural ingredients is produced, which is conducted by separately heating quantities of virgin and fractionated coconut oil appropriate to pre-defined proportions to 65-70 degrees C.

This is preferably conducted in two different vessels so that the vessels are each placed in another vessel containing water, which is heated directly.

When the above-mentioned temperature is reached, the virgin and fractionated coconut oils are mixed together and stirred for 4 minutes until it is determined that the mixture is homogenous enough. Then the natural emulsifier is added, preferably Dermofeel Viscolid, then, when this is completely dissolved, when the mixture is in the range of 25-30 degrees C, the natural vitamin E is added, then the refined, edible sodium bicarbonate, while using indirect cooling, the temperature is reduced to 18 degrees C. This is preferably done by holding the vessel is continuously held in water of 15-18 degrees C. When a range of 18-20 degrees C is reached, if desired, the scent is mixed in, then the mixture cooled to 11 degrees C, at which temperature it is held for one hour. Finally, the mixture is returned to room temperature (20-25 degrees C) and left there until it regains its liquid form.

In the course of this process, the blending of ingredients may be facilitated by gentle shaking. On the basis of the above, it may be established that our invention has met the objectives set for it in every respect and that its advantages may be summarised as follows:

By contrast to other preparations based on natural materials, it offers significant antibacterial and antifungal properties

- It binds free radicals and thus slows the aging of the skin

- It does not inhibit, but rather merely absorbs perspiration, and thus does not obstruct the natural excretion of toxins by the skin

It has a natural scent that is not overpowering and thus can be used by those who are susceptible to allergies

- It does not irritate the skin

- Although it is made from coconut oil, the user need not fear that it will solidify and thus become unusable for even a short period of time
