Abstract
A composition contains certain nutrients, active and protective substances, as well as an oxygen carrier, along with a process for preparing this composition and its use. The composition provides skin care preparation with a high oxygen content which also contain further nutrients, active and/or protective substances. The new functional oxygenated composition contains (a) phospholipids and oxygen-loaded fluorocarbon or fluorocarbon mixtures. The proportion of fluorocarbon lies in the 0.2 to 100% by weight/volume range. The lipid fraction contains 30 to 99% by weight phosphatidylcholine in the form of asymmetric lamellar aggregates. The composition also contains (b) a product obtained by gentle disintegration of suspensions or dispersions of cells of plant substances, bacteria or yeasts by ultrasonic and/or high-pressure homogenization under up to 25 MPa; and (c) a cosmetic or dermatological carrier suitable for use on the skin. This composition is based for its oxygen content on the synergy between fluorocarbons and the disintegration products.
