Definitions

  • a known form of cosmetic preparations are low-viscosity cosmetic preparations which are applied to the facial skin after it has been cleansed. A conventional skin moisturizing agent is then applied.
  • the use of the thin-bodied cosmetic preparation between the washing process and the application of the day care is used in particular to supply the skin with moisture and thus prepare it for the subsequent care step.
  • the low-viscosity preparations of the present invention are surprisingly able to better stabilize air bubbles that are suspended in it by shaking the preparation, so that they remain within the preparation for longer and do not immediately bubble out of it. It was particularly surprising that such stabilization is possible, since mostly preparations must be significantly more viscous in order to stabilize air bubbles within the preparation.
  • the present invention relates to a cosmetic acrylate-free preparation comprising xanthan gum and having a viscosity at 25 ° C. in the range from 30 to 150 mPa ⁇ s.
  • the invention also relates to the use of xanthan gum for stabilizing suspended air bubbles in a cosmetic, acrylate-free preparation having a viscosity at 25 ° C. in the range from 30 to 150 mPa.s.
  • acrylate-free means that the preparation of the invention does not contain any polymers which have been obtained from homo- or copolymerization with acrylic and / or methacrylic acid.
  • normal conditions means 20 ° C, 1013 hPa and a relative humidity of 50%.
  • skin it preferably refers to human skin.
  • viscosity values relate to a measurement at 25 ° C in a 150 ml wide neck bottle (VWR no .: 807-001) using Rheomat R 123 from proRheo.
  • the Rheomat R 123 from proRheo GmbH is a rotational viscometer, ie a measuring body rotates in the substance to be measured. The force is measured that is required to make the measuring body rotate in the sample at a specified speed. The viscosity is calculated from this torque, the speed of the measuring body and the geometric dimensions of the measuring system used.
  • the measuring body no.3 (article no. 200 0193), suitable for a viscosity range up to 1000 mPa-s, speed range 62.5 mim 1 , is used. Unless otherwise specified, the viscosity measurement is always carried out 24 hours after the preparation has been made.
  • stabilization of air bubbles is understood according to the invention to mean that the air bubbles remain suspended in the preparation over a longer period and do not simply bubble out of it.
  • the cosmetic preparation according to the invention is characterized in that it contains xanthan gum.
  • the proportion of xanthan gum is advantageously from 0.05 to 0.45 % By weight, preferably from 0.075 to 0.3% by weight and particularly preferably from 0.09 to 0.23% by weight, based in each case on the total weight of the preparation.

  • Ex. X represent examples according to the invention, while the examples which are designated with Cf. X are not according to the invention.
  • the letter X stands for an integer number.
  • Example 1 For this purpose, the preparations were first filled into a glass vessel and waited until no more air bubbles were visible to the eye in the preparations. Each preparation was then shaken for 10 seconds so that as many air bubbles as possible were suspended in the preparation. After shaking, the glasses were set down and the behavior of the air bubbles was observed. It was surprisingly found that Example 1 according to the invention stabilizes the air bubbles suspended by the shaking significantly better after 1 minute than the comparative examples Comp.1, Comp.2 and Comp.3. The comparative examples showed no more air bubbles around the lower area of the preparation after one minute, while Example 1 contained significantly more suspended air bubbles in the lower area. Furthermore, it was surprisingly found that the preparation of Example Ex.1 was comparatively transparent and thus made it possible to look like water.
