Definitions

  • the present invention belongs to the cosmetic field and relates to a specific combination of an ester and a polymer, which allows, after application to the skin, to protect the skin from the deposition of particulate matter from the air. Hence, after application the deposition of particulate matter from the air to the skin is reduced.
  • a beautiful and attractive appearance is a desire for many people.
  • One typical sign of such an appearance is a healthy and smooth looking skin. Therefore, in order to take care on the skin, it is for many people a daily routine to apply cosmetic products such as body lotions and sunscreen compositions.
  • compositions containing UV-filters are commonly used to protect the skin from the ultraviolet radiation of the sunlight.
  • acute damage severe burn
  • long-term damage such as an increased risk of skin cancer occurs in case of excessive irradiation with light from the UVB range (wavelength: 280-320 nm).
  • the excessive exposure of UVB and UVA radiation (wavelength: 320-400 nm) also leads to a weakening of the elastic and collagen fibers of the connective tissue. This leads to numerous photo-toxic and photo- allergic reactions and results in premature skin ageing.
  • UVA and UVB filters are grouped in the most developed countries in the form of positive lists such as Annex VI of the Regulation (EC) No 1223/2009 of the European Parliament and of the Council.
  • particulate matter is understood as solid matter suspended in the earth’s atmosphere. Sources of particulate matter can be natural or anthropogenic.
  • a special kind of particulate matter are particles from smog, tabacco smoke and flying ash, which appearance may be caused by forest fires, smoking or the exhaust of engines.
  • Such particulate matter usually has a diameter in the range from 0.01 pm to 100 pm, wherein smog and tobacco smoke typically cover the range from 0.01 pm to 2.5pm.
  • particulate matter especially from smog and tobacco smoke, may adversely affect the human health. Inhalation of such particles may lead to an increased risk of lung cancer.
  • high concentration of such particulate matter in the air also leads to an increased particle deposition on the skin. The correlation between high concentration of particulate matter in the air and the effect on the skin has recently been evaluated in a number of scientific studies.
  • Cosmetic products are often used to protect the human skin from environmental effects.
