摘要:
The strain of the microorganism Penicillium oxalicum var. Armeniaca CCM 8242 produces an anthraquinonyl carboxylic acid derivative of structural formula (I), which may be used as a colorant, especially as a food colorant or cosmetic colorant.
摘要:
The invention relates to colouring and toning agents for keratinous fibres, in particular human hair, comprising at least one hydroxyanthraquinone derivative of formula (I), as a direct dye, in a cosmetically acceptable vehicle, where R = a group of formula (II), where R to R = independently, H; OH; C1 to C4 alkoxy; C1 to C4 alkyl; C1 to C4 fluoroalkyl; carboxy; NO2; halogen; a group of formula SR , where R = H or C1 to C4 alkyl; a group of formula PhCH2COOR , where R = H, C1 to C4 alkyl or a physiologically acceptable cation or, any two neighbouring groups of R to R form a methylenedioxy ring and X = halogen. The inventive agents permit hair colouring with outstanding fastness.
摘要:
A nanolubricant composition is described where the lubricant composition includes a flowable oil or grease with nanoparticles dispersed in the flowable oil or grease. The nanoparticles are configured to polish a surface of a structure slowly over a period of time. The nanoparticles a hardness of at least about 7 Mohs and a diameter that is less than one half the arithmetic average roughness of the surface or a length that is less than one half of the arithmetic average roughness of the surface.
