Definitions

  • This invention relates to a system for delivering cosmetic agents to various parts of the body. More particularly, the invention relates to methods and apparatus for delivering cosmetic agents to for example the skin or other target areas of the body using the principle of electrostatic spraying.
  • Conventional sprays also suffer from the inability to provide 100% coverage of a given target, e.g. all areas of the surface of hair fibres, all areas of the surface of the skin (which is not flat and presents a very rough terrain on a microscopic scale), or areas of the body surface which are ordinarily, or as a result of some disability, difficult to reach.
  • a given target e.g. all areas of the surface of hair fibres, all areas of the surface of the skin (which is not flat and presents a very rough terrain on a microscopic scale), or areas of the body surface which are ordinarily, or as a result of some disability, difficult to reach.
  • electrostatic spraying of liquid and solid materials In a very different technical field, the principle of electrostatic spraying of liquid and solid materials is also known. In this technique a formulation to be sprayed is raised to a high electric potential in a spray nozzle to cause the formulation to atomise as a spray of electrically charged droplets. Such electrically charged droplets seek the closest earthed object to discharge their electric charge, and this can be arranged to be the desired spray target. Hitherto, electrostatic spraying techniques have been proposed principally for only large-scale industrial and agricultural applications, especially for delivering reactive materials like paints, adhesives and other surface coatings, as well as large-scale delivery of pesticides and other agricultural or agrochemical formulations.
  • Examples of disclosures in this field include GB-A-1393333, GB-A-1569707, GB-A-2092025, EP-A-029301, EP-A-253539 and WO-A-85/00761, the contents of which disclosures are incorporated herein by reference.
  • EP-A-224352 suggests the use of an electrostatic sprayer for delivering a pharmaceutically active agent to the eye, to replace conventional ocular treatment using eye drops.
  • JP-A-56-97214 suggests the use of electrostatic spraying for applying a granular (i.e. solid particles of) colouring material to hair to effect surface coating thereof.
  • a granular (i.e. solid particles of) colouring material instead of colouring substances is mentioned, apparently speculatively, but the disclosed system is unsuitable as far as consumer applicability and appeal is concerned and still suffers from some of the disadvantages mentioned above, particularly atmospheric contamination and non-localised application.
  • US 4776515 proposes an electrodynamic fine particle negative ion generator adapted to spray various liquids, particularly water, but possibly also alcohol, perfume, ammonia, liquid medications and surfactants.
  • the object of the disclosed system is to provide an ozone-free mist of negatively ionised liquid particles, (which presupposes that the material to be sprayed is ionizable), and the mist that is produced instantly disperses into an open area in which the apparatus is operated, e.g. a room, so that a far-reaching, uniform aerosol is generated which has particular applicability for large public areas such as .hospitals, restaurants and offices.
  • this system is unsuitable for small-scale personal use and in many of its objects goes directly against the principles upon which a solution to the above mentioned prior art problems must be founded.
  • the present invention provides a method of delivering a cosmetic agent to the body, comprising electrostatically spraying said cosmetic agent thereon.
  • the method of this aspect of the invention preferably comprises:
  • the present invention provides an apparatus for delivering a cosmetic agent to the body, comprising:
  • the present invention provides, in combination, the apparatus as defined above and an electrostatically sprayable composition consisting of or containing a cosmetic agent to be delivered to the body.
  • the cosmetic agent to be delivered may be any cosmetic agent conventionally applied by known aerosol spray regimes, but is preferably an agent which is normally applied to the body to impart one or more desirable sensory benefits, preferably those benefits associated with smell, touch or feeling.
  • body is intended to exclude the hair and encompass only those areas of the body upon which cosmetic agents are used to provide one or more sensory benefits which are perceived by smell or touch or feeling.
  • novel delivery systems in accordance with this invention have also been found to give unusual and unexpected sensory results upon delivery of a variety of cosmetic actives to the body, especially the back, legs and arms.
  • the 360° wrap-around, high product capture, silent, invisible and non-wet spray characteristics are among those features which present themselves as particularly novel and beneficial in this context.
  • Cosmetic agents which may be delivered using the system of the present invention may be any of a wide range of materials used to impart one or more sensory benefits to a region of the body, such as the skin, to which they are applied.
  • Preferred cosmetic actives which may be used either singly or in combination, are those which impart a deodorant, antibacterial, freshening, moisturising or conditioning benefit, examples of which agents are well known in the art. Examples of suitable cosmetic actives of the above types include the following:
  • Particularly useful materials to which the invention can be applied are deodorant materials, such as those found in conventional body sprays which contain as a principal active agent one or more perfumes.
  • a particular advantage of the present invention is that it allows at least some of, or even substantially all of, the adjunct components as conventionally used in body sprays and other cosmetic spray products to be omitted, thereby giving rise to a simpler and cheaper delivery system, with less waste. (This, however, will generally not apply to solvents, diluents or carriers, which are preferably still present, as discussed further below.) Any such adjunct components may however still be used within the scope of this invention if desired or as necessary.
  • the cosmetic agent to be delivered in accordance with the invention is in the form of a composition containing one or more solvents, diluents or carriers for the cosmetic agent, with or without minor amounts of one or more adjunct materials as are known in the art or as will be described further hereinbelow.
  • Suitable solvents, diluents or carriers are those which are soluble in or solubilise or are miscible with the cosmetic active(s) to be delivered.
  • suitable solvents or diluents include for example alcohols or polyols such as ethanol, isopropyl alcohol, propylene glycol, dipropylene glycol, phenylethyl alcohol, glycerol, 1,3-butane diol, 1,2-propane diol, isoprene glycol.
  • alcohols or polyols such as ethanol, isopropyl alcohol, propylene glycol, dipropylene glycol, phenylethyl alcohol, glycerol, 1,3-butane diol, 1,2-propane diol, isoprene glycol.
  • the concentration of cosmetic active(s) may vary widely and may be selected for example in accordance with the type of material being delivered, other spraying parameters of the system and/or the needs or wishes of a user. Suitable concentrations of active may be in the range of from about 0.01% by weight to about 99% by weight of the composition, more preferably from about 0.1% to about 80% by weight.
  • cosmetic actives of the types exemplified above may be used effectively in concentrations represented by the following exemplary amounts:
  • compositions to be delivered using the present invention are preferably liquids.
  • any adjunct materials which are also included are preferably also liquid at room temperature, though may optionally be solids if used in minor amounts and do not deprive the composition of being electrostatically sprayable.
  • combinations of one or more active cosmetic agents may be delivered simultaneously, either from the same composition sprayed from a single delivery means of the apparatus, or by delivering different cosmetic agents simultaneously from different delivery means.
  • compositions useful in the present invention that they be electrostatically sprayable.
  • resistivity A principal characteristic of such electrostatically sprayable compositions which it will usually be necessary to carefully select or adjust as necessary (as discussed further below), is their resistivity.
  • Preferred resistivities fall within the range from about 104 to about 1012 ohm cm, more preferably from about 106 to about 1010 ohm cm. Resistivities of lower than 104 may possibly be used. Resistivities of more than about 1012, e.g. up to about 1014 or more, may also be used, though such values are difficult to measure using cheap, conventional resistance measuring apparatus. Resistivity is measured using standard, conventional apparatus and methods, generally at 25°C.
  • compositions for delivery using the present invention are substantially non-aqueous or may contain only a small amount of water, e.g. less than 10% by weight, preferably less than 5% by weight, even more preferably less than 1% by weight. This is because, due to its low resistivity, a predominantly aqueous composition is generally difficult to spray effectively using electrostatic means.
  • resistivity adjusting materials examples and suitable amounts of which will be either known to persons skilled in the art or readily derivable by simple experiment.
  • polar substances such as alcohols, e.g. ethanol
  • non-polar substances e.g. oils and other hydrophobic materials
  • suitable resistivity adjusting agents include charged species such as salts, e.g. sodium chloride, or a salt conventionally used in buffers in personal products or pharmacological formulations.
  • any resistivity adjusting agent that is used preferably solubilises or is soluble in, or is miscible with, the cosmetic agent or composition containing same.
  • compositions of a wide range of viscosities may be suitable for use in the present invention, but suitably the viscosity is in the range of from about 0.1 to about 50000 mPas, more preferably from about 0.1 to about 10000 mPas, even more preferably from about 0.5 to about 5000 mPas (at 25°C).
  • viscosity adjusting agents may be included. Examples of such agents include salts, e.g. alkali metal or ammonium halides, polymers and conventional thickening materials and oils and polar oil thickeners such as cosmetic oils, waxes, glycerides and suitable amphiphiles with melting points of for example >20°C.
  • the hardware and electrical componentry and circuitry may be of any suitable construction and design.
  • the art of electrostatic spraying contains many examples of suitable apparatus which may be used in the present invention and such disclosures of such apparatus or particular features thereof may be applied either singly or in combination to the spray systems of the present invention.
  • suitable electrostatic spraying hardware include, in addition to those of the prior art references mentioned above, those of the following published references: GB-A-2061769, GB-A-2073052, EP-A-031649, EP-A-132062, EP-A-163390, EP-A-171184, EP-A-234842, EP-A-243031, EP-A-368494, EP-A-441501, EP-A-468735 and EP-A-468736; the disclosures of all of which are incorporated herein by reference.
  • inventions of the apparatus of the present invention include for example: voltage generated by the high voltage generator and power source, electric field strength in or in the region of the product delivery means, flow rate of the product to be sprayed from the reservoir to and out of the delivery means, size and configuration of the delivery means itself and construction and properties of any product feed mechanism utilised between the reservoir and the output of the delivery means.
  • preferred voltages generated by the high voltage generator from the power source are in the range of from about 5 to about 20 kilovolts, more preferably from about 12 to about 18 kilovolts. Voltages of more than 20 kilovolts, e.g. up to about 24 kilovolts or more, may be used if desired, for instance for products to be sprayed having particularly low resistivities, e.g. less than about 106 ohm cm and/or particularly high flow rates, e.g. >5 mls/min. The most suitable voltage for a given system may depend upon the product to be sprayed, as well as other parameters, all of which will generally be selected to give an overall optimised system.
  • Electric field strengths which are responsible for the spraying action of the electrostatic apparatus will be largely dependent upon the voltage applied. However, field strengths may be controlled or adjusted if necessary, for example by changes in nozzle configuration or geometry and/or the use of field intensifying electrodes, which are well known in the art cited above.
  • Optimum flow rates of material to be sprayed may often depend upon the composition of the product to be delivered, e.g. upon the concentration of the "active" cosmetic ingredient being applied. Also, as already mentioned with respect to viscosity of the sprayable material, a suitable flow rate may be selected depending upon the particular delivery regime and/or habit or needs of a user.
  • preferred flow rates of compositions for delivery in accordance with embodiments of the invention are in the range of from about 0.001 to about 10 ml/min, more preferably from about 0.1 to about 5 ml/min, even more preferably from about 1 to about 3 ml/min, per delivery means.
  • the size and configuration of the one or more delivery means in the apparatus of the invention may be of any suitable form and again may be selected in association with other parameters to give an optimised functioning electrostatic spray delivery system.
  • the or each delivery means will be in the form of a nozzle, preferably of insulating or semi-insulating material such as plastics or various polymers, as is well known in the art.
  • a conduit for carrying the product to be sprayed terminates in an orifice at the tip of the nozzle, from which orifice the product is ejected for example initially as a ligament but in any event eventually dispersing as a spray of charged droplets.
  • the orifice preferably has a diameter of not greater than about 400 microns, more preferably not greater than about 350 microns. Even more preferably the orifice has a diameter of between about 125 and about 250 microns.
  • the delivery means may advantageously include metering means to provide a dosing mechanism for delivering a predetermined fixed amount of material from the or each nozzle.
  • metering means to provide a dosing mechanism for delivering a predetermined fixed amount of material from the or each nozzle.
  • Such an expedient may for example be useful in conjunction with a system having a controlled flow rate.
  • the or each delivery means is in communication, i.e. preferably fluid communication, with the reservoir or reservoirs (if for example more than one cosmetic agent or composition is to be desired to be sprayed from the same apparatus or even the same delivery means) by virtue of product feed means.
  • feed means preferably comprises a hollow conduit through which the material or composition passes for example under the effect of capillary action.
  • alternative or additional feed means may be provided, for example a pump. This may be of any suitable type, e.g.
  • the feed means may comprise a wick, e.g. a porous wick, through and/or over which the product to be sprayed flows before reaching the point of high electric field strength where it is dispersed as a charged spray of droplets or particles.
  • the apparatus preferably include a trigger (i.e. a manual control means) or alternatively an automatic control means to selectively apply the high voltage from the generator to the or each delivery means to electrostatically spray the cosmetic agent or composition onto the body at an intended site.
  • a trigger i.e. a manual control means
  • an automatic control means to selectively apply the high voltage from the generator to the or each delivery means to electrostatically spray the cosmetic agent or composition onto the body at an intended site.
  • Any other suitable control means however, e.g. which automatically control actuation of the system, may be used, as will be appreciated by persons skilled in the art.
  • the spraying apparatus is constructed with a similar size, shape and weight to a conventional aerosol spray, so as to form a hand-held unit which is easy to manipulate and use and suitable for personal use.
  • the apparatus comprises an elongate housing 1, which is preferably electrically insulating, e.g. of a plastics material, within which the electrical and other hardware components of the apparatus are mounted.
  • a battery 8 such as a conventional low voltage, e.g. 1.5 to 12, particularly 9, volts, cell, which location allows ready access to the battery for the purpose of replacement when necessary.
  • the high voltage generator which converts the low voltage from the battery 8 into the high voltage of for example between about 12 and 18 kilovolts, which is required for raising the product to be sprayed to the high electric potential necessary to effect electrostatic spraying thereof.
  • Suitable components of the high voltage generator 6 are well known in the art and comprise principally a coil or transformer to perform the voltage step-up function.
  • various packing elements of electrically insulating material such as that shown as 7 in Figure 1, may be provided in order to increase the safety aspect of the high voltage apparatus and to reduce unwanted leakage paths to earth when the apparatus is in use.
  • circuit boards 12 Connected between the battery 8 and high voltage generator 6, as well as between the high voltage generator 6 and the remaining electrical components of the apparatus, are one or more circuit boards 12 containing any necessary auxiliary electrical componentry for ensuring effective and satisfactory functioning of the apparatus.
  • additional circuit board(s) 12 may comprise for example DC/AC (or vice versa) converters, as well as voltage adjustment means to control the high voltage applied to the product delivery means from which the product to be sprayed is to be delivered.
  • reservoir 2 which in this preferred embodiment is a bagin-can type reservoir, as known per se in the art of personal products and spraying apparatus.

  • a nozzle 14 In fluid communication, via a conduit 16, with the reservoir 2 is a nozzle 14, which is connected electrically to the high voltage electrics of the apparatus so that the product within the nozzle is raised to the high electric potential necessary to effect its egress from the nozzle under electrostatic forces and thus the electrostatic spraying thereof.
  • the nozzle 14 comprises an internal chamber 17 which terminates at the tip of the nozzle in an orifice 18 from which the product within the chamber 17 emerges under the influence of the electrostatic forces.
  • the orifice 18 most suitably has a diameter of between about 125 and about 250 microns and the flow rate of product emerging therefrom is most preferably in the range of about 1 to 3 ml/min.

  • the apparatus is preferably provided with some kind of cap 30 for protecting the nozzle 14 and other delicate components in the upper region of the apparatus from physical damage or contamination when the apparatus is not in use.
  • a manual trigger which constitutes control means for selectively energising the unit to apply the high voltage to the nozzle to electrostatically spray the product therefrom.
  • the trigger like the other elements of the apparatus subject to unwanted voltage leakage or shock risk, is preferably constructed and situated to minimise such problems, expedients for which are known in the art.
  • FIG. 2 shows schematically a magnified embodiment of the apparatus of the invention
  • the main form and construction of the apparatus is much the same as described above, except that here the position and configuration of certain components has been modified.
  • the reservoir 2′ containing the product to be sprayed is now constructed as a positive pressure product feed device incorporating a diaphragm pump, the latter being well known in the art of pumps.
