摘要:
Deodorizing or antibacterial compositions, in particular for use in cosmetic or topical formulations, characterized in that they comprisea) at least one 3,7,11-trimethyl-2,6,10-dodecatrien-1-ol,b) at least one phenyl hydroxyalkyl ether having one, two or three carbon atoms in the alkyl radical,c) at least one glycerol monoester of a short-chain or medium-chain fatty acid andd) optionally glycerol monolaurate.
摘要:
The invention provides a cosmetic or dermatological method for detecting and/or selectively quantifying individual microorganisms, and/or whole groups of microorganisms, which are present on human or animal skin, comprising the steps of removing a sample of the microflora of the human or animal skin, treating the sample with a deinhibiting medium, adding the treated sample to a culture medium which exhibits favorable growth conditions for a defined group of microorganisms but unfavorable growth conditions for other microorganisms, to produce a selective culture, and incubating the selective culture over a sufficiently long period of time, to allow only the group of microorganisms for which the culture medium exhibits favorable growth conditions the opportunity to multiply, in association with metabolic products, in particular CO.sub.2, produced which collect either in the culture medium itself or in a test vessel which is provided for the purpose and which contains an indicator medium, and the concentration of the metabolic products is elucidated by means of the change in the alternating current (AC) resistance of the culture medium and/or the indicator medium in the test vessel and, after appropriate calibration, is correlated by means of arithmetical methods with the number of microorganisms in the selective medium.
摘要:
A method for treating skin afflicted with blemishes or acne with a composition comprising distilled wool wax acids and at least one monoglycerol monocarboxylic acid monoester is presented.
摘要:
Microemulsion gels based on microemulsions of the oil-in-water type in which the droplets of the discontinuous oily phase are joined to one another by one or more crosslinking substances, the molecules of which are distinguished by at least one hydrophilic region, which has an extension which is capable of bridging the customary distance between the microemulsion droplets, and by at least one hydrophobic region, which is capable of entering into a hydrophobic interaction with the microemulsion droplets.
摘要:
Lipsticks, antiacne sticks, sunscreen sticks and eyeshadow sticks, with a high water content, characterized in that they comprise (a) a lipid phase, which comprises (a1) at least one oil component (a2) at least one wax component (a3) optionally other substances soluble or dispersible in the lipid phase, (b) an aqueous phase, which comprises (b1) from 30 to 85% by weight of water, based on the total weight of the stick composition and (b2) if desired, substances soluble or dispersible in water, (c) at least one active ingredient or several chosen from the active ingredients known for lipsticks, antiacne sticks, sunscreen sticks and eyeshadow sticks, (d) a W/O emulsifier or a mixture of two or more W/O emulsifiers, (e) one or more stabilizers, chosen from the group of substances of the general structure A—B—A′, where A and A′ are identical or different hydrophobic organic radicals, and B is a hydrophilic group, (f) if desired, further surface-active substances as coemulsifiers, and also, if desired, stabilizers and further customary cosmetic and/or pharmaceutical auxiliaries, active ingredients and/or additives.
摘要:
A system automatically mixes a first audio signal and a second audio signal. The system includes a correlator that determines whether the first signal and the second signal are correlated according to a predetermined correlation criterion. If the predetermined correlation criterion is fulfilled, the correlator determines whether the first and the second signal are delayed. A delay circuit compensates for the delay between the first signal and the second signal. A mixer mixes the first signal and the second signal that includes a compensation.
