Definitions

  • Cosmetic powders have long been used to care for and mechanically protect the skin, or to dry and cool it. Cosmetic powders are also used as deodorants. Make-up powder has also been known for a long time in decorative cosmetics.
  • a wide variety of applicators are used depending on the intended use of the powder. Children's powders are mainly offered in sprinkles so that the powder can be sprinkled on the skin of a child who is preferably lying down. Make-up powder is often applied with a tassel or a brush so that the required, fine and targeted distribution of the powder can be achieved. It is customary today to process deodorant (or deodorant) powder in rod-shaped compacts so that they can be used as a "compact powder deodorant stick", the powder being transferred to the skin essentially by abrasion. Deodorant powders are also filled into a can with a propellant gas as an aerosol so that they can then be spread over the skin using a spray head.
  • the task is to develop a powder deodorant by means of which a free-flowing cosmetic powder can be applied to the skin using a suitable application system.
  • a free-flowing powder is filled into containers which can be equipped with a so-called roll-on system.
  • roll-on systems per se have long been known and are used, e.g. described in GB 1 583 323, preferably used for the application of liquid deodorant formulations.
  • a corresponding, commercially available roll-on applicator is shown in FIG. 1.
  • Such roll-on applicators are usually characterized in that they comprise an applicator ball which has an essentially smooth surface. The active substance is transferred from the inside of the container to the user's skin by rotating the ball. Roll-on applicators themselves have proven their worth.
  • Both GB 1 583 323 and GB-A-2 108 052 disclose roll-on applicators which, for the purpose of applying powders, comprise applicator balls which have a surface roughened especially for this purpose.
  • the roughening of this spherical surface is that it is equipped with many small depressions or elevations, which should enable powder to be transferred from the container to the skin when the ball is rotated.
  • These bumps, which are distributed over the entire applicator ball, are specified in both cited documents as an indispensable means for the correct functioning of a powder roll-on.
  • GB 1 583 323 also describes the use of a membrane which seals off the powder container against the roll-on applicator and is intended to prevent the powder from "trickling out” or "flowing out”.
  • An exemplary, commercially available roll-on applicator can be placed on a powder container or closed off.
  • the applicator ball 1, the ball guide 2 and the insertion groove 3 for a powder container (not shown), as well as the effective gap 4 between the applicator ball 1 and ball guide 2 are clearly shown in FIG. 1.
  • the applicator with ball guide and ball can also be molded directly onto the powder container or the powder roll-on system can additionally comprise a transition piece between the applicator and powder container.
  • a preferred embodiment comprises a powder container for the free-flowing deodorant powder and a roll-on applicator ball 1 located thereon, which is movably mounted in a ball guide 2 so that when the ball 1 is rotated or rolled, it is applied to the skin , Powder from the inside of the powder container on the ball surface through the effective gap 4 between the smooth applicator ball 1 and the ball guide 2 to the outside and is transferred to the skin.
  • the surface of the applicator ball 1 is judged to be smooth if indentations or elevations are neither planned nor carried out therein, that is, if the ball 1 is manufactured with a smooth surface within the scope of the manufacturing tolerances.
  • This effective gap width of a commercial roll-on is usually less than 0.5 mm.
  • An effective gap width which is approximately between 0.03 mm and 0.3 mm, has proven to be particularly suitable.
  • the granularity of the powder can be adapted to the gap width of a commercial roll-on. For example, it has been shown that the amount of powder that can be applied directly decreases if its average grain size exceeds half the width of the effective gap.
  • Powders with an average grain size of less than 200 ⁇ m are preferred. Powders with an average grain diameter of 5 to 50 ⁇ m have proven particularly suitable.
  • a second analysis of a corresponding sample shows its grain size distribution: Table 1 Grain size distribution talc Grain diameter proportion of up to 1 ⁇ m 3.0% 1 to 5 ⁇ m 12.0% 5 to 10 ⁇ m 15.0% 10 to 20 ⁇ m 28.0% 20 to 40 ⁇ m 30.0% 40 to 75 ⁇ m 11.5% over 75 ⁇ m 0.5%
  • the relative opening of the roll-on is defined as the ratio of the effective gap width between the applicator ball and ball guide to the grain diameter of the deodorant powder, then at least a relative opening of 2: 1 should advantageously be maintained.
  • a relative opening of less than 1: 1 would be pointless since - in addition to the smallest powder grains - practically no powder could escape.
  • too large a relative opening leads to uncontrolled pouring out or pouring out of the powder. So it will always be a matter of finding a favorable compromise for the relative opening.
  • a relative opening of 20: 1 as the maximum and 1: 1 as the minimum was assumed, and the area could possibly be increased further if the adhesion between the grains of the powder used permits.
  • a preferably relative opening of approximately 10: 1 to 2: 1 was assumed.
  • the optimal ratio of gap width to granularity of the deodorant powder is determined by the surface quality of the applicator ball. It could therefore, with slightly modified spherical surface, other ratios can also be defined as usable.
  • the ball size or the ball diameter has a further influence on the applicability of the deodorant powder. An applicator ball with a diameter of 25.4 mm is preferred.
  • Variation of the individual or variation of combinations of the listed parameters such as ball diameter, roughness of the ball surface, gap width between applicator ball and ball guide, granularity of the deodorant powder, and ratio of the gap width between applicator ball and ball guide to the granularity of the free-flowing deodorant powder are of course in the range present invention.
