  • Patent number: 5916577
    Abstract: The invention concerns cosmetic agents with condensates of plant and animal decomposition products, which can be used in cosmetic body care and cleansing preparations and which, in addition to the emulsifying effect, have essential skin-care properties. The object of the invention is to prepare cosmetic products from plant and animal starting materials, said products having substantial portions of original biological structures but being modified to such an extent that they are cosmetically acceptable owing to their neutral smell and pale color. According to the invention, the cosmetic agent is a product of a direct and mild (20 to 55.degree. C.; pH 7.5 to 8.5) decomposition of a biological starting material in an aqueous medium, subsequent condensation with a sub-stoechiometric amount of a C.sub.10 to C.sub.20 fatty acid halide or mixture and optionally subsequent etherification or esterification of the condensation product.

  • Patent number: 5885558
    Abstract: The invention concerns a sun-protection preparation with an increased light-protection factor, consisting of (A) a fine-particle, crosslinked poly(methylsiloxane) with a particle size ranging from 1 to 10 .mu.m, the poly(methylsiloxane) having given further parameters, (B) octyldodecylneopentanoate, (C) formulation aids, and (D) additives. The ratio of (A) to (B) ranges from 1:2 to 10, and the portion of (A) and (B) ranges from 3 to 12 wt %, relative to the total composition.

  • Patent number: 5885564
    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.

  • Patent number: 5800835
    Abstract: The invention relates to a preparation for improving the blood supply. The problem with prior art preparations or processes resides in the fact that soft magnetic components had to be introduced into the body in capsule form or a magnetic field had to be applied after the application of demagnetized particles to the skin. The purpose of the invention is to provide a novel preparation for improving the blood supply in which special hard magnetic particles are used. According to the invention, the preparation for improving the blood supply consists of a pharmaceutically or cosmetically acceptable medium and possibly further additives containing finely distributed hard magnetic single-grade particles with a high coercitive field intensity and grain sizes in the range of 600 to 1200 nm. Dispersions of this preparation exhibit no aggregation of the hard magnetic particles. The preferred use is in the cosmetic and dermatological field.

  • Patent number: 5716599
    Abstract: The invention involves a cosmetic preparation containing kaolin which may be employed as a mask, lotion, gel or cream with a non-sticky, non-plasticized consistency and with a content of white kaolin with a high proportion of kaolinite and spherical inorganic particles of a particle size of less than 5 .mu.m, with a proportion of spherical particles in the kaolin mixture of 0.5 to 10% by weight as well as a cosmetic skin care composition, in which the proportion of the kaolin/spherical particle mixture falls within the range of over 2 to 65% by weight of the composition as a whole. The viscosity of the composition with the proportion of kaolin/spherical particles is around 2000 to over 15,000 cps higher than a similar composition with kaolin only and without spherical particles, with the difference in viscosity increasing with the proportion of kaolin/spherical particles.
