摘要:
Biological material is suspended in a liquid and, in the presence of reverberative bodies suspended in the suspension of biological material, subjected to ultrasound thereby to disintegrate the biological material. The disintegration is conducted in a spherical chamber at approximately the center of which is the radiating surface of a sonotrode. The diameter of the chamber is at least three times the diameter of the radiating surface and the radiating surface faces the bottom of the chamber. The suspension of the biological material is pumped upwards through the chamber.

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.

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. The new, pleasantly soft preparation with an inhibitive effect with regard to inflammation permits high kaolin contents to be used to especially good effect in masks and gels.
摘要:
A multi-phase sunscreen agent, characterized by at least two phases that are liquid to pasty or gelatinous and separate from each other spontaneously within seconds to less than ten minutes after a brief and gentle mixing process lasting less than one minute without any essential application of force, where at least one phase contains a UV filter.

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.

The invention relates to a stable multiple phase emulsion of the O.sub.1 /W/O.sub.2 type with high proportions of the primary O.sub.1 /W emulsion. The new emulsions have an emulsifier-free primary oil-in-water phase consisting of a viscoplastic aqueous gel containing the finely distributed inner oil droplets together with a gelling agent, wherein the thixotropic primary oil-in-water phase has a yield point in the range from 20 to 100 Pa and a plastic viscosity of 0.01 to 0.1 Pa.multidot.s and contains at least one lipophilic agent in the primary oil; and a secondary oil phase in which the primary oil-in-water phase is present together with a lipophilic emulsifier; and wherein the proportion of the inner oily phase is from 10 to 35 % by weight relative to the total weight of the emulsion. The higher proportions of the inner oily phase render possible higher proportions of organic sun protection agents with simultaneous avoidance of skin irritations.
摘要:
A preparation for stimulating the blood circulation of the skin comprising a dispersion containing a proportion of finely divided magnetically hard single-domain particles in the dispersion being in the range from 0.01% to 70% by weight, based on the total weight of the dispersion; these particles having a strong coercive field and being in the range 600 to 1200 nm; and the magnetically hard single-domain particles are selected from the group consisting of barium hexaferrite, strontium hexaferrite, undoped barium hexaferrite, undoped strontium hexaferrite, and the mixtures thereof; and the balance up to 100% by weight of a cosmetic or pharmaceutical excipient carrier substance or a pharmaceutical additive, based on the total weight of the dispersion.
摘要:
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. The starting materials can be yeasts, yeast fractions, pulses, pulse fractions, pectins, pectin-containing masses, algae, algae fractions, animal milk, animal milk fractions and their mixtures, and contain helical natural substance components, enzyme structures and vitamin structures.
摘要:
A process capable of being continuously carried out, for disintegrating cell material in the form of dispersions or suspensions in water for the purpose of obtaining cell constituent. Selected parameters permit avoidance of use of solid ultrasonication activators and the establishment of a particular geometry form for the acoustic irradiation container. The parameters include sonotrode immersion angle, length of immersion, ratio of extent of immersion of the sonotrode relative to the acoustic irradiation volume and the ratio of extent of immersion to the solid matter content of the medium to be sonicated.
