Provided are microemulsions comprising: (a) at least one alkyl (oligo)glycoside, (b)at least one cosurfactant different from (a), (c)at least one non-water-soluble organic oil component, (d) at least one moisturizing agent, (e) and water. These microemulsions may be used for producing cleaning compositions and also cosmetic cleaning compositions,comprising: (A) any microemulsion provided herein, (B) one or more anionic surfactants, (C) one or more cationic polymers; (D) optionally further surfactants; (E)optionally cosmetic additives, and (F) water.

Use of microemulsions in cosmetic cleaning compositions

The present invention is concerned with a method of preparing a MALDI sample, the method comprising the steps of: (a) mixing a solid sample precursor comprising sample and matrix to form a solid sample mixture; (b) applying the solid sample mixture to a sample cavity of a MALDI target; and (c) compressing the solid sample mixture in the sample cavity so as to form a MALDI sample surface for laser desorption. The present invention also provides a MALDI target comprising a sample cavity for receiving a MALDI sample, the sample cavity having (a) a desorption end portion comprising an aperture, such that a portion of the MALDI sample exposed at the aperture is in use subjected to laser desorption; and wherein the sample cavity also has (b) a compression end portion adapted to permit compression of a solid sample mixture towards the desorption end portion in the sample cavity by applying a compression force to the solid sample mixture via the compression end portion.
