Definitions
- the present invention belongs to the cosmetic field and relates to a specific use of cosmetic ingredients allowing for an effective protection of the human skin from particulate matter by forming by protective layer or conditioning the skin in a way such that particulate matter does less adhere to the skin and can be washed away easily with tap water.
- 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 0.01pm to 100 pm, wherein smog and tobacco smoke typically cover the range from 0.01pm 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.
- the US2007/0003536 discloses a method for protecting human skin against oxidizing species and oxidative damages of the skin.
- the document is addressed to environmental effects, it does not address the easy and effective removal of particulate matter after deposition from the air.
- the US2002/0192178 discloses a method for protecting the skin against the effects of pollution, comprising the application of a composition which contains an aqueous extract of maize.
- the extract of the invention is used as a heavy metal-scavening agent.
- the document does not address the easy and effective removal of particulate matter after deposition from the air.
- compositions which can be applied to the skin before the exposure to the particulate matter and which allow an easy and effective removal of the deposited material with water after exposure The application of conventional skin care products such as body lotions and creams usually results in the fact that particulate matter deposited on the treated section cannot easily be removed with tap water. In most cases it is necessary to use cleansing formulations including surfactants for an effective removal of the particulate matter. As a result surfactants are unnecessarily released into the sewage system causing higher efforts in the purification process before releasing the water back to the environment.
- a first object of the invention is the use of a cosmetic oil in water emulsion comprising, based on the total weight of the emulsion, from 0.8 to 13% by weight of an oil phase and at least one emulsifier to condition human skin such that particulate matter, which is deposited onto the skin after application of the emulsion, can be rinsed off the skin with water.
- a second object of the invention is a method to protect the human skin from particulate matter and/or pollution involving the following steps i. application of a cosmetic oil in water comprising, based on the total weight of the emulsion, from 0.8 to 13% by weight of an oil phase and at least one emulsifier to the human skin, ii. exposure of the skin to particulate matter from the environment, and iii. washing off the particulate matter deposited from the skin using tap water.
- a further object of the invention is use of a cosmetic oil in water emulsion comprising, based on the total weight of the emulsion, from 0.8 to 13% by weight of an oil phase and at least one emulsifier to form a protective layer or protective barrier on the human skin, whereby the protective layer or barrier allows particulate matter, which is deposited onto the skin after application of the emulsion, to be rinsed off the skin with water.
- a further object of the invention is use of a cosmetic oil in water emulsion comprising, based on the total weight of the emulsion, from 0.8 to 13% by weight of an oil phase and at least one emulsifier to protect human skin from particulate matter upon application of the emulsion, whereby the protective layer allows particulate matter, which is deposited onto the skin after application of the emulsion, to be rinsed off the skin with water.
- a further aspect of the present invention is a cosmetic oil in water emulsion comprising, based on the total weight of the emulsion, from 0.8 to 13% by weight of an oil phase and at least one emulsifier.
- normal conditions refers to 20°C, 1013 hPa and a relative humidity of 50%.
- All disclosed values for the interfacial tension towards water relate to a temperature of 20°C. Furthermore, the disclosed values for the interfacial tension towards water relate to 1013 hPa and a relative humidity of 50%.
- the terms ..according to the invention”, “preferred according to the invention” and so on are always directed to the use according to the invention, to the method according to the invention and to the cosmetic emulsion according to the invention.
- the term "free from” means that the proportion of the respective substance is less than 0.05% by weight. This ensures that entrainments or impurities with these substances are not included as “free from” according to the invention.
- skin refers solely to the human skin.
- Emulsifiers are understood to be all substances which are listed in the International Cosmetic Ingredient Dictionary and Handbook, Thirteenth Edition 2010, (ISBN 1-882621-47-6) under the name "emulsifying agent”.
- Surfactants are understood to be all substances which are listed in the International Cosmetic Ingredient Dictionary and Handbook, Thirteenth Edition 2010, (ISBN 1-882621-47-6) under the name "surfactant”.
- emulsifier and surfactants are not considered as part of the oil phase.
- Emulsions here in particular W/O, O/W or W/O/W emulsions, are often used as cosmetic or medical preparations.
- Emulsions are generally understood as meaning heterogeneous systems which comprise two liquids which are immiscible or only miscible with one another to a limited extent, which liquids are normally referred to as phases.
- one of the two liquids is dispersed in the other liquid in the form of very fine droplets.
- O/W emulsion oil in water emulsion
- the basic character of an O/W emulsion is determined by the water.
