Definitions

  • This invention relates to a system for delivering benefit agents or treatment agents directly to the hair and/or scalp. More particularly, the invention relates to methods and apparatus for applying such agents onto the hair and/or scalp using the principle of electrostatic spraying.
  • wash-and-rinse-off products are frequently used to condition the hair and also to assist styling, i.e. to impart body to the hair and enable it to more easily hold a style.
  • Many of these regimes are location dependent, for example are restricted to use in the bathroom, they are messy, inconvenient and time consuming, and have poor deposition efficiency and so lead to inefficient and unnecessarily costly use of raw materials.
  • 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 benefit or treatment agent to the hair and/or scalp, comprising electrostatically spraying the benefit or treatment agent onto the hair and/or scalp under regulation of delivery localisation means which cause the said agent to be delivered preferentially to the hair and/or scalp and away from (or at least preferentially away from) a user's eyes or other body parts.
  • the method of this aspect of the invention preferably comprises:
  • the present invention provides an apparatus for delivering a benefit or treatment agent to the hair and/or scalp, comprising:
  • the present invention provides, in combination, the apparatus as defined above and an electrostatically sprayable composition consisting of or containing a benefit or treatment agent to be deposited onto the hair and/or scalp.
  • the delivery localisation means may take any of several different forms, which may be utilised either singly or in combination.
  • the delivery localisation means comprise a hair brush or comb assembly in combination with the other elements of the system, so that the benefit or treatment agent can be delivered locally and with accuracy during a normal brushing or combing regime.
  • brushing devices which deliver liquid to the hair are per se known (e.g. a squeeze-handle brush)
  • such known devices have certain defects when in use, such as limited control of liquid flow and poor sensory performance due to easy excessive delivery of product, and, as a result, difficulty in achieving the exact desired hair condition which may even require subsequent washing or other post-treatment to achieve the desired result.
  • the delivery means of the apparatus are contained at least partially within the hair brush or comb assembly and preferably a plurality of such delivery means are provided, especially for example evenly distributed in the assembly.
  • the provision of this combined system conveniently allows the reservoir, high voltage generator and control means of the apparatus, together with any other components which may be present, e.g. electrical circuitry, to be contained within the hair brush or comb assembly, so as to provide an essentially self-contained, light, compact apparatus which is convenient and easy to use and has considerable consumer appeal.
  • the electricity source e.g. a battery
  • the whole assembly is designed so as to be a hand-held appliance, i.e. suitable for personal use.
  • the delivery localisation means may be constituted by other expedients.
  • the apparatus as defined above may include proximity sensing means which allow or cause the unit to operate only when the delivery means are suitably close to the intended target, namely the hair and/or scalp, as appropriate to the particular use.
  • the use of one or more delivery means having a particular directionality may assist the desired operation of this expedient.
  • the delivery localisation means may be constituted by an optimisation of structure and/or arrangement of components of the apparatus, as well as an optimisation of variable operation conditions such as voltage, electric field intensity and other physical or electical characteristics of the apparatus, and even physical and/or chemical properties of the material or materials to be delivered.
  • the delivery localisation means may be provided not as part of the spraying apparatus, but constituted by particular selection or adjustment of one or more physical and/or chemical properties of the substrate, i.e. the hair and/or the scalp, onto which the benefit or treatment agent is to be delivered.
  • Surface modification or activation for example, the importance of which is already known for certain electrodeposition systems in other technical fields, may be used in this context.
  • Figure 1 is a schematic axial sectional view of one preferred embodiment of the apparatus according to the invention.
  • the benefit or treatment agents which may be delivered using the system of the present invention can be any of a very wide range of materials.
  • Conventional delivery systems such as wash-and-rinse-off compositions and hair sprays by necessity include one or more, usually several, ingredients which form at least part of a deposition/delivery system -which is not directly associated with the particular cosmetic or therapeutic benefit which it is desired to achieve.
  • a particular advantage of the present invention is that it allows at least some of, or even substantially all of, such auxiliary components to be omitted from a conventional composition comprising the "active" material to be delivered. Any such auxiliary components may however still be used within the scope of this invention if desired or as necessary.
  • compositions useful in the present invention that they be electrostatically sprayable.
  • resistivity A principal characteristic of such electrostatically sprayable materials or 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 to be delivered using the present invention are preferably liquids. If the benefit or treatment agent is itself liquid at room temperature, then it may be suitable for delivery on its own. Alternatively it may be combined with one or more adjunct materials which 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.
  • the treatment or benefit agent is preferably incorporated into a liquid-based system, for example by being combined with a diluent or solvent with or without additional components which are already known for use in cosmetic compositions.
  • compositions consisting of or containing the one or more benefit or treatment agents to be delivered to the hair and/or scalp in accordance with the invention may include any of the following:
  • compositions for delivery using the present invention are non-aqueous or may contain only a small amount of water, e.g. less than 10% by weight, preferably less than 5% wt, even more preferably, less than 1% wt. This is because, due to its low resistivity, a predominantly aqueous composition is generally difficult to spray effictively using electrostatic means.
  • compositions for treating the hair and/or scalp in accordance with the invention are leave-on compositions, so it is generally preferred not to include any components which are disadvantageous in that respect and may impart deleterious effects to the hair and/or scalp when applied thereto and left on.
  • 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 agents are charged species such as salts, e.g. sodium chloride, or a salt conventionally used in buffers in personal products or pharmacological formulations.
  • Products 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).
  • one or more 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.
  • Viscosity may in fact be used as a parameter to control the rate of delivery of the benefit or treatment agent to the intended site, if, as has been found with many embodiments of the system of the invention, it has a substantially inverse proportionality relationship with the flow rate of the material from the delivery means. For example, a particular delivery regime or a habit or need of a user may dictate an optimum delivery rate of the particular benefit or treatment agent being applied, in which case careful selection of the viscosity of the material to be sprayed can provide a self-regulating deposition mechanism.
  • 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 2 to about 18 kilovolts, more preferably from about 2 to about 10 kilovolts, possibly even more preferably from about 6 to about 8 kilovolts.
  • 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 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 will often depend upon the composition of the product itself, e.g. upon the concentration of the "active" 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. By way of example, preferred flow rates of compositions for delivery in accordance with embodiments of the invention are in the range of from about 0.00001 to about 0.01 ml/sec, more preferably from about 0.0001 to about 0.001 ml/sec. These flow rates will generally be for a single given product delivery means, e.g. per nozzle.
  • the apparatus of the invention which employ a plurality of such delivery means, it may be more appropriate to base the selected flow rate on the overall total flow rate of all the delivery means, in which case the optimum flow rate per delivery means may be correspondingly lower than the above preferred values.
  • 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.
  • 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 material 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.
  • product 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 feed means may comprise a hollow conduit through which the composition passes under the effect of capillary action.
  • special feed means may be provided, for example a pump.
  • This may be of any suitable type, e.g. electrically operated, but more conveniently it may be a simple mechanical device which exerts pressure on the reservoir containing the composition to be sprayed, such that the composition therein is forced out of the reservoir to the delivery means.
  • 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 benefit or treatment agent onto the hair and/or scalp.
  • 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 benefit or treatment agent onto the hair and/or scalp.
  • 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.
  • one problem which has been encountered is that of static build-up on the hair fibres. This is caused by the charged particles or droplets of the spray being deposited upon impact with the hair target, thereby transferring their charge onto the hair fibres so as to build up a corresponding electrostatic charge thereon. This effect is unwanted under normal operations, because it results in limited or low product capture, since the charge build up on the hair repels the like-charged droplets or particles of subsequent spray, thereby limiting or reducing (or even preventing) further spray reaching the hair target.
  • the anti-static build up means may take any of several forms.
  • One particularly useful expedient is to arrange for the high voltage circuitry of the apparatus to provide an output which alternates between opposite polarities, the frequency of the alternating output being such that each cloud of atomised droplets or particles charged with one polarity issues from the delivery means or nozzle substantially without discharging the droplets or particles of a preceding cloud carrying the opposite charge at least while the successive clouds are airborne.
  • This technique as applied to prior art electrostatic spraying systems, is disclosed and described for example in EP-A-468735, the disclosure of which is incorporated herein by reference.
  • a further expedient for achieving this anti-static build up effect is to wet the hair, e.g. with water, prior to spraying. This increases the conductivity of the hair surface, facilitating electrostatic charge redistribution and conduction to the user's body which constitutes earth.
  • a further expedient for this same purpose is to surface-treat the hair with one or more known antistatic agents, such as those which are already known for use in hair conditioning compositions.
  • the treatment may be a pre-treatment prior to spraying or alternatively a suitable anti-static agent may be incorporated into the electrostatically sprayable composition to be delivered.
  • the above described phenomenon of static build up on the hair fibres may in fact be of practical benefit, in that it tends to cause the sprayed droplets or particles to be targetted preferentially at the scalp surface itself rather than at the intermediate regions of hair fibres growing therefrom.
  • the present invention provides a particularly effective system for treating the scalp, possibly even preferentially to treatment of the hair.
  • Liquid reservoir 2, high voltage generator 4 and battery 6 are all contained within a generally cylindrical, preferably insulating, housing 1.
  • the generator 4 and battery 6 are conveniently situated in a handle portion 12 of the housing 1 and the reservoir 2 in a brush (or alternatively comb) portion 14 thereof, the latter being provided with conventional outwardly extending bristles or teeth, or other brush/comb elements 18.
  • the battery 6 may be a conventional low voltage (e.g. 6 volt) cell as used in a variety of small scale domestic or personal appliances, and may be of a rechargeable type.
  • the high voltage generator 4 generates at its output the high voltage for charging the material to be electrostatically sprayed, which voltage may be selected and/or adjusted as already discussed.
  • Additional circuitry 10 may optionally be included depending upon the characteristics of the system, but for example may frequently be required for converting the alternating current output from the generator 4 into a direct current for supply to the delivery elements 8. If necessary additional circuitry may also be provided between the power source 6 and high voltage generator 4.
  • a general on/off power switch 19 and liquid feed control 20 are also provided at convenient points on the housing 1.
  • the liquid feed control 20 may for example be an on/off type switch or a variable control, depending upon the electrical hardware used and the use to which the apparatus is to be put.
  • the power switch 19 and liquid feed control 20 may if desired be combined into a single component performing both functions.
  • liquid delivery elements 8 Leading from the reservoir 2 and in fluid communication therewith are a plurality of liquid delivery elements 8, each of which extends through the housing wall into the region occupied by the brush/comb elements 18.

  • various forms of product feed means may be provided between the liquid reservoir 2 and delivery elements 8.
  • the liquid feed control 20 is operated to deliver liquid benefit or treatment agent from the reservoir 2 to the free ends of the delivery elements 8, from which the liquid is electrostatically sprayed into the region occupied by the brush elements 18 and delivered to the hair and/or to the scalp, as appropriate.
  • the apparatus which is preferably designed to be a hand-held appliance, is able to deliver benefit or treatment agents onto the hair and/or scalp in a controlled manner during a brushing or combing regime using electrostatic forces to spray the liquid at a flow rate appropriate for the material being delivered and/or the needs or wishes of the user.
