Kosmetisches und dermatologisches Mittel auf Basis von hartmagnetischen Teilchen

摘要

The invention relates to a cosmetic and dermatological agent for treating sensitive tissue, wounds and hair. The inventive agent contains: (a1) hard magnetic particles such as barium- or strontium hexaferrite monocrystals, samarium cobalt (SmCo) particles and neodymium-iron-boron particles (Nd2Fe14B), each with a particle size of between 80 and 550 nm, and a particle coercitive field strength of 1000 to 20000 Oersteds; or (a2) particles as per (a1), encapsulated in aqueous liposomes or asymmetric lamellar aggregates, said aggregates consisting of natural phospholipids containing 30 to 99 weight per cent phosphatidylcholin, and fluorocarbons; and in addition to (a1) or (a2), or a mixture of the two, asymmetric lamellar aggregates without encapsulated particles, which are only loaded with oxygen to the extent of their saturation limit. The inventive agent also contains carrier substances and optionally other cosmetic or pharmacological active substances.
