  • Effervescent granules may usually be prepared from a combination of citric and tartaric acid rather than from a single acid because the use of either acid alone may cause difficulties. When tartaric acid is the sole acid, the resulting granules readily crumble and lack mechanical strength.
  • Citric acid alone may result in a sticky mixture which is difficult to granulate during the manufacturing process.
  • Effervescent salts may include the following ingredients, which may actually produce the effervescence: sodium bicarbonate, citric acid and tartaric acid. When added to water the acids and base may react to liberate carbon dioxide, resulting in effervescence. It should be noted that any acid-base combination which results in the liberation of carbon dioxide could be used in place of this combination as long as the ingredients are suitable for pharmaceutical use.

Natural particles may include sand, pumice, ground nut shells, ground apricot or peach pits etc. Synthetic materials used for abrasive surfaces may include plastic or polyethylene microbeads and the like.
  • a perfect lubricant for effervescent products must be nontoxic and water-soluble. Very few traditional lubricants fulfill these requirements. Intrinsic lubricants are added to the powder mixture and consequently included in the formulation. When added in solid form, the lubricant will have to be finely divided. Metal stearates, such as magnesium or calcium stearate that serve as lubricants in conventional tablets, are seldom used as intrinsic lubricants in connection with effervescent tablets due to their insolubility in water. Use of stearates results in an undissolved, foamy, soapy- tasting layer on the surface of the cloudy solution. In addition, normal lubricant concentrations of metal stearates make the tablets hydrophobic, which entail a slow dissolution of the effervescent tablet in the water.
  • Disintegrants which are used in conventional tablets, are not normally used in effervescent tablets because one of the marketing demands is that a clear solution should be obtained within a few minutes after adding the tablet to a glass of cold water.

  • Abrasive surface 200 may contain holes or may be permeable or porous. Materials soaked into spacer 198 may be released from sponge like spacer 198 during usage of head 904 as head 904 is pressed against the treated skin.
  • Materials contained inside compartment 190 or soaked into spacer 198 may include, inter alia, anti-hair regrowth materials, or any other material having a desired effect on the treated skin as described hereinabove.
  • Figs. 11A and 11B depict a side and isometric views, respectively, of head 906 including disk 900 fitted with abrasive module 202.
  • Abrasive module 202 may include dome shaped body 206 having an abrasive surface 208, wherein body 206 is made from compounds to be rubbed and released during the usage of head 102. These compounds may include, inter alia, anti-hair regrowth materials, or any other material having a desired effect on the treated skin as described hereinabove. If effervescent effect is needed an appropriate material may be applied to the treated skin prior to applying the abrasive module 202. For example, if body 206 includes CO 2 loaded zeolite, water or other aqueous solution or gel may be applied to the treated skin prior to treatment. If body 206 includes the first material of the chemical reaction, the second material may be applied to the skin before treatment.
  • Figs. 12A and 12B depict a side and isometric views, respectively, of head 908 including disk 900 fitted with abrasive module 210.
  • Abrasive module 210 may include head 102 and abrasive surface 214.
  • Fig. 13 is a schematic illustration of an exemplary multi head hair removal system 222 according to some embodiments of the present invention.
  • Hair removal system 222 may include at least two heads 113, wherein each head is assembled on a dedicated gear system 115.
  • Heads 113 may be similar to any of heads 102, 123, 109, 161 , 902, 904, 906 and 908 (shown in Figs. 1, 2, 5, 6A, 6B, 7A, 7B, 8A, 8B, 9A, 9B, 10A, 10B, 11A, 11B, 12A and 12B).
  • Gear systems 115 may be similar to gear systems 111, 112 depicted in Figs.
  • Each pair of a head 113 and a gear system 115 composes an abrasive sub-system 222 and 224.
  • Abrasive sub-systems 222 and 224 may operate separately or together, synchronized or un-synchronized, wherein each head 113 may tilt as needed, for example in order to follow changes in the curvatures of the treated skin.
  • the two sub-systems 222 and 224 are operated together and are synchronized with each other, as shown by arrows 226.
  • hair removal system 222 may include more than two heads 113, wherein each head is assembled on a dedicated gear system 115, as needed.
  • Apparatus 1100 may comprise compartment 1102 which is formed to contain a first active material in the form of fluid or gel and to be used also as a handle. Compartment 1102 may be squeezable to allow squeezing compartment 1102 by a user. Compartment 1102 may be connected to mediator element 1104 at a first end of compartment 1102. Mediator 1104 may comprise a passage allowing the first active material to flow from compartment 1102 towards tablet 1106 connectable to the other end mediator 1104.
  • Tablet 1106 may be formed to fit onto the other end of mediator element 1104 and may be connected to it by one of various possible means, such as snap-to, adhesive, and others.
  • Tablet 1106 may include a second active material and may be formed with an abrasive surface 1109 at a facet of tablet 1106 facing away from compartment 1102 and towards the treated skin.
  • Tablet 1106 may be formed with hole 1108 in it. Hole 1108 may fit the passage (not shown) leading the first active material from compartment 1102 so as to allow the first active material to pass through it and wet abrasive surface 1109 of tablet 1106, and react with the second active material thus creating the effervescent effect.
  • the outer circumference 1105 of mediator 1104 may be formed with rounded and soft edge on the side facing the treated skin to provide soft and smooth touch with the skin when approaching the end of the tablet during treatment. Outer circumference 1105 may be formed to protrude outwardly from the diameter of compartment 1102, to prevent undesired touch of long nails with the treated skin.
  • the user may press abrasive surface 1109 of apparatus 1100 against the treated skin in circular movements, while squeezing compartment 1102.
  • apparatus 1100 may pull and rotate the hair and hair follicle, while filing the hair, and the effervescence effect of the chemical reaction of the first and second materials may push and force the anti-hair regrowth materials that may be provided either in compartment 1102 or in tablet 1106, or in both, into the treated skin, and specifically, into the hair follicle.
  • apparatus 1100 exfoliates the skin, and the effervescence effect of the chemical reaction of the first and second materials may push and force the desired materials that may be provided either in compartment 1102 or in tablet 1106, or in both, into the treated skin.

Abstract

L'invention concerne un procédé et un appareil assurant un traitement cosmétique de la peau, comprenant un matériau chimiquement actif sous forme solide et de préférence sous forme de pastilles, et un second matériau qui réagit chimiquement avec le premier matériau de manière à produire une effervescence pendant la réaction. Les matériaux chimiquement actifs peuvent être activés par l'utilisateur afin d'assurer un traitement cosmétique de la peau. L'activation engendre une effervescence qui pousse les granules de matériaux réactifs sur la peau. La taille des granules diminue au cours de la réaction, assurant ainsi un pelage de plus en plus fin de la peau.
