Definitions
- the present invention relates to a tear strip used in a hair removal operation with depilatory wax, more particularly for removing a layer of wax deposited in the molten state on the skin.
- the methods known in the prior art for performing depilation with depilatory wax mainly consist in coating an area of skin with a depilatory wax applied in a liquid or pasty state on the latter in order to trap the hairs, wait a certain time for the wax to harden and then pluck the hairs together with the strip of wax.
- the depilatory wax compositions used are generally applied hot to the skin.
- strips of wax coated with preheating are used, or devices applying a layer of wax which are then removed with or without a supporting strip.
- a depilatory strip is described in document US 1 620 539, the strip being constituted by a flexible support, in particular a strip of gauze on which a layer of depilatory wax is deposited.
- the strip is heated before it is applied to the skin, it is then deposited on the skin and finally removed, after cooling, by pulling out with the hairs to which it had adhered.
- the heating temperature of such a strip must be strictly controlled in order to avoid burns when it is applied to the skin.
- the use of such bands is not very practical, because it is necessary to use different types of bands for the different areas of skin to be depilated.
- a waxing appliance is described in patent application FR 2 706 261 in the name of the applicant.
- This device comprises a housing intended to be held in the hand, containing a reservoir of product to be applied in thermal relation with heating means, as well as an applicator roller disposed in the vicinity of an outlet orifice for the reservoir and intended to apply the heated product, in particular the depilatory wax to the skin.
- Depilatory wax is a wax of the self-supporting rosin type which is heated, then applied in a strip of uniform thickness to the skin and torn off once the wax has hardened by pulling the strip of wax in the opposite direction to that of removal. .
- the tearing was quite long, because we had to wait until the strip deposited on the skin hardened, it was quite difficult to grasp the end of the strip in sight that it can even stick to the user's fingers.
- Another type of device and depilation technique is also known from the state of the art, consisting in the simultaneous heating of a quantity of wax stored in the tank of an device, followed by the application, in particular with a roller apply a layer of wax to the skin and remove the wax using a tear strip.
- the document FR 2 520 601 describes such a device and a hair removal technique using it.
- the strip applied by the roller is subsequently removed by applying a strip of fabric over it which is torn off with the trapped hairs once the wax has cooled.
- the quality of hair removal depends very much on the viscosity of the wax, which in turn is a function of the heating temperature and is very sensitive to ambient temperature, or even to the temperature of the user's skin surface.
- the quality and effectiveness of hair removal depends mainly on the quality of the layer of wax applied to the skin.
- the depilatory composition must be very fluid.
- the depilatory composition to adhere well to the hairs to be depilated, it is necessary for its viscosity to be greater than when depositing it in a thin layer.
- the object of the invention is to remedy at least in part the aforementioned drawbacks and to propose a tear strip which makes it possible to obtain a good compromise between the thickness and the uniformity of the layer of wax applied on the one hand and its adhesion to the hair to be plucked on the other hand.
- Another object of the invention is to allow an epilation operation which is effective, while reducing the pain felt during the pulling of the hairs.
- An additional object of the invention is a tear-off strip that is easy to industrialize for a lower manufacturing cost.
- a tear strip intended to be applied to an area of skin covered with a layer of depilatory wax
- the strip comprising a support made of a flexible material, since said support contains a material for changing phase having a transition temperature lower than that of application of the depilatory wax to the skin where said phase change material is loaded with calories by contact with the wax layer.
- tear strip support is understood a piece of fabric, of a nonwoven material, of paper, of cellophane, of plastic film or of any other material in sheet or thin plate, relatively flexible, on which a composition adheres depilatory wax type.
- the support may have a rectangular shape or any other shape adapting to that of the area to be epilated.
- the tear strip is intended to be applied to the area of skin coated with said composition and then removed, with the hairs included, by pulling sharply on one of the ends of the strip.
- phase change material is meant a material which has the capacity to change state, reversibly, within a certain range of temperatures: from solid to liquid state or vice versa from liquid to solid.
- the energy necessary to change state is absorbed from the surrounding environment and is used to cross the barrier which separates the two states.
- the measured temperature of the material during its phase change is constant until the phase change is complete, the heat flow through such material is delayed during heating and also cooling when the phase change takes place .
- transition temperature of the phase change material it is understood, in the context of the invention, the melting temperature of said material or the temperature corresponding to the solid - liquid transition.
- the upper limit of the temperature for applying depilatory wax to the skin is determined by the temperature of the threshold for pain caused by heat, which is approximately 45 ° C.
- the backing of the tear strip is applied to an area of skin covered with a heated depilatory wax composition and applied in a thin and uniform layer to the skin.
- the heat of the wax layer is transmitted by conduction to the strip support which is pressed against the skin in order to obtain good contact with the wax layer which is applied to it.
- the phase-change material of the strip support then becomes charged with heat by direct contact with the wax layer, heat which is stored by the material until it reaches its melting temperature. At this time, the phase change material melts at constant temperature. A very large amount of heat is absorbed by the phase change material, an amount of heat which is equal to the change in enthalpy associated with this transformation.
- the fact that the calories are absorbed by the phase change material causes a local lowering of the temperature of the wax layer, which increases the viscosity of the applied layer and subsequently increases its adhesion to the hairs to be plucked. .
- the transition temperature of said phase change material is between 25 and 35 ° C.
- phase change material having the above-mentioned values of its transition temperature ensures a good lowering of the local temperature of the layer of wax applied, taking into account the ratio between the volume of the layer of wax and that of the support containing the phase change material.
- transition temperature of the phase change material is lower than that of human skin, it has been found in laboratory tests that a drop in the temperature of the wax layer provides a pain relieving effect when pulling hairs out with the band. This contributes to the comfort of hair removal and partially alleviates the vasodilating effect of heat.
- said support contains at least two different types of phase change materials.
- phase change material is characterized by its transition temperature, in this case of melting, and by its capacity to store heat, expressed in J / g.
- transition temperature in this case of melting
- capacity to store heat expressed in J / g.
- said phase change material is a paraffin.
- paraffin a paraffinic hydrocarbon which has melting temperatures in the above range and good heat storage capacities.
- paraffins can be, for example, heneicosane, peicosane, nonadecane, octadecane, heptadecane, etc.
- paraffin is very well supported by the skin, it can be brought into contact with the latter without causing allergies or undesirable skin reactions.
- phase change material is contained in a plurality of microcapsules distributed in said support.
- phase change material it would certainly have been possible to apply the phase change material by spraying on the tear strip support, or by coating one side of the strip with such a material, even by dipping the strip support in a bath. of such a material, support then wrapped in a protective film.
- the protective envelope prevents the flow of the phase change material in liquid phase and allows it to return to the initial state within the limits of the envelope.
- microcapsules also have the advantage of having good resistance to mechanical actions (pressure, traction, shearing) and good chemical stability (washing, contact with the components of the depilatory wax), while having constant dimensions which allows their application in a uniform layer on the tape support or allows them to be well mixed with the fibers of the support.
- said material is applied to the internal face of said strip in a layer with a thickness of less than 3mm, preferably between 0.01 mm and 0.5mm.
- the microcapsules in a uniform layer on the internal face of the support of the strip, in particular the face intended to be applied on the area. coated with wax, the thickness of the layer of micro capsules having to be in this case comparable to that of the layer of wax applied to the skin, preferably less than the latter.
- microcapsules are suspended in an aqueous solution in a proportion of 30 to 80% by weight of microcapsules.
- An aqueous solution of such a concentration makes it easy to transport the microcapsules to the support, while obtaining the necessary quantity after the water has evaporated.
- a binder in aqueous suspension is added to said solution of microcapsules in a proportion of between 0 and 50% by weight of binder.
- This binder can for example be an acrylic type emulsion which has good adhesion properties to the fibers of the strip support and allows better attachment of the particles to the support, resulting in better resistance to the mechanical actions carried out on the strip or to successive washings of the strip.
- phase change material is deposited by spraying on said support.
- This solution has the advantage of being easy to implement, since the micro capsules are quickly deposited on their support, the latter adhering to the fibers of the support after drying.
- said wax is a water-soluble depilatory wax comprising at least one sugar.
- Said sugar is chosen from the group comprising sucrose, fructose, glucose, honey, maple syrup, invert sugars, alone or as a mixture.
- depilatory wax is a viscous substance of the non-hardening adhesive type. She is initially heated to around 50 ° C so that it can be applied in a thin layer on the skin and is then removed with the hairs which it encompasses using a tear strip placed on the area of skin covered with wax .
- said wax is a depilatory wax of the rosin type.
- depilatory wax of the rosin type is understood a depilatory composition of the resin type, that is to say based on rosin (comprising resin acids) or modified rosin, beeswax or paraffin and optionally comprising an elastomer or other thermoplastics.
- rosin comprising resin acids
- modified rosin comprising resin acids
- beeswax or paraffin comprising an elastomer or other thermoplastics.
- Such a wax is in the solid state at room temperature and must be heated to about 70 ° -80 ° C to make it fluid for application to the skin. Once applied to the skin, the wax strip can be removed by pulling on one of its ends or by affixing a support strip and thus removing it with the latter.
- the depilatory wax may be a mixture of a rosin-type wax with an aqueous solution, or with a water-soluble depilatory wax based on sugar or any other water-dispersible mixture of waxes to be epilated, optionally comprising a surfactant or other additives.
- the tear strip of the invention comprises micro capsules containing cosmetic active ingredients.
- These cosmetic active agents are chosen from the group comprising perfumes, essential oils, opacifiers, antiseptics, analgesics, refreshing agents, for example menthol, dyes, plasticizers, salts, alone or as a mixture.
- These products can also be micro-encapsulated and are applied to the tape support in the same way, or even at the same time by being mixed in the same aqueous solution before application, their use having the aim of making the hair removal operation more pleasant. .
- said support is treated by spraying with an aqueous solution comprising a proportion of 95% to 40% by weight of a first solution, comprising 38.6% by weight of micro capsules of a paraffin having a melting temperature of 25 ° C in aqueous suspension, mixed with 5% to 60% of a second solution, comprising 50% by weight of an acrylic binder in aqueous suspension.

- a tear strip according to the invention comprises a support consisting of a piece of fabric, for example raw or bleached cotton, or of a non-woven material, for example polyester, or knitted, or of cellophane, paper, plastic film or any other material in sheet or thin plate, being relatively flexible in order to easily adapt to the shape and the relief of the area of skin to be depilated.
- This support must have good properties of resistance to mechanical stresses carried out by the user on one of the ends of the strip, in particular to tearing, to shearing, as well as to traction.
- a tear strip support for depilating the legs is rectangular in length between 10 cm and 30 cm and a width between 4 cm and 8 cm.
- the phase change material is chosen from the group of paraffinic hydrocarbons having a melting temperature below 45 ° C.
- paraffinic hydrocarbons can be, for example, heneicosan, the melting point of which is 40.5 ° C.
- phase change material is contained in protective gelatin envelopes of microcapsules having dimensions of, for example, between 1 and 40 ⁇ m. These microcapsules can be integrated into the fibers of the support, in foams then bonded to the support, or in coating layers.
- said support is treated by spraying with an aqueous solution comprising a proportion of 95% to 40% by weight of a first solution, comprising 38.6% by weight of microcapsules of a paraffin having a melting temperature of 25 ° C in aqueous suspension, mixed with 5% to 60% of a second solution, comprising 50% by weight of an acrylic binder in aqueous suspension.
- Cosmetic additives or active ingredients in the form of micro capsules in a proportion of 0 to 15% can also be incorporated into the solution.
- a non-woven polyester strip is taken as support, several possible mixtures have been tested to obtain, in the dry state, a predetermined weight of microcapsules and of binder relative to the weight of the support strip which is, for example, 1 g.
- a predetermined weight of microcapsules and of binder relative to the weight of the support strip which is, for example, 1 g.
- to obtain 80% by weight of microcapsules and 5% of binder relative to the weight of said support strip 2.14 g of a 95% mixture of solution containing 38.6% of micro capsules in aqueous suspension and 5% solution comprising 50% of acrylic binder in aqueous suspension.
- a third embodiment of the invention to obtain 50% by weight of microcapsules and 20% of binder relative to the weight of said support strip, 1.7 g of a 75% mixture of solution containing 38.6% of micro capsules in aqueous suspension and 25% solution comprising 50% of acrylic binder in aqueous suspension.
- a fourth embodiment of the invention to obtain 10% by weight of microcapsules and 5% of binder relative to the weight of said support strip, 0.36 g of a 72% solution mixture containing 38.6% of micro capsules in aqueous suspension and 28% solution comprising 50% of acrylic binder in aqueous suspension.
- a fifth embodiment of the invention to obtain 10% by weight of microcapsules and 20% of binder relative to the weight of said support strip, 0.66 g of a mixture 40% of solution containing 38.6% of micro capsules in aqueous suspension and 60% solution comprising 50% of acrylic binder in aqueous suspension.
- the strip support is coated on one of its faces, in particular that which will be applied to the area of skin to be depilated, with the previously described solution which is sprayed onto said support.
- the tape is then dried in a ventilated oven at 60 ° C to remove the water.
- the strip thus obtained is ready to be used, several uses and successive washes being possible with such a strip.
- a thin layer is applied to the skin, for example with a thickness of between 0.5 mm and 1 mm, of a depilatory composition warmed to a temperature between 50 ° C. and 70 ° C. depending on the type of depilatory composition used.
- the temperature of application of the layer of wax to the skin can be equal to or less than 45 ° C.
- a tear strip treated as previously described is then applied to the area of skin coated with depilatory wax.
- the micro capsules of the band support absorb the calories stored by the wax, which causes a decrease in the local temperature of the layer of wax and, at the same time, an increase in the viscosity of the wax resulting in a better efficiency at hair removal.
- the comfort of hair removal is improved and it is partially offset by the vasodilating effect due to the temperature of application of the wax to the skin.
- phase change material whether or not contained in microcapsules
- the phase change material is caught in the wax strip and can be removed with the latter when it is torn off.
- the wax can only be removed with a tear strip
- thermochromic material in another variant, provision may also be made to coat the external face of said support with a thermochromic material and, by the change in color, to follow the drop in temperature which has occurred following the application of the phase change material to the skin.
