An aqueous composition for sandblast resist ink comprising an aqueous dispersible polymer having a minimum film-forming temperature of 10°C or lower and a water-soluble polymer as a film-forming auxiliary agent, and a method of sandblasting using the aqueous composition are disclosed. The aqueous composition produces a sandblast resist ink which can produce a dry film having a degree of swelling in the range of 0.1-1.5 in water at 20°C. The resist mask can be produced by using this aqueous composition as the sandblast resist ink without using any organic solvents in all steps (e.g. the resist mask formation step and the resist mask removed step) of sandblast processing for producing relief of photographic images, patterns, letters, or characters on the surface of glass, stones, ceramics, metals, plastics, woods, and the like.
The present invention provides a thickening composition simultaneously exhibiting suitable thickening performance and superior usability, which contains N-long-chain acyl acidic amino acid and/or a salt thereof, an amphipathic substance, an inorganic salt, and water as essential components, and has a viscosity of not less than 200 mPa·s. By the addition of the thickening composition, moreover, cleansing compositions and cosmetic compositions for skin, hair and the like, which maintain thickening performance and usability, while containing N-long-chain acyl acidic amino acid and/or a salt thereof are provided.

(EN) There is provided a method of treating skin with a therapeutic, water-soluble organic acid. There is also provided an anhydrous composition composition containing the water-soluble organic acid encapsulated into hydrophobic microspheres through which the oranic acid can elute in the presence of water is applied to the skin. The composition is wet with water immediately prior to, or after the composition is applied to the skin.(FR) L'invention porte sur un procédé de traitement de la peau par un acide organique thérapeutique, soluble dans l'eau, ainsi que sur une composition anhydre renfermant l'acide organique soluble dans l'eau qui est encapsulée dans des microsphères hydrophobes par lesquelles l'acide organique peut s'échapper en présence d'eau, cette composition étant appliquée sur la peau. La composition est mouillée avec de l'eau immédiatement avant ou après son application sur la peau.
The application of amino acid ionic liquids as additives in the ultrasound-assisted extraction of plant material
study was to determine the antioxidant activity of the aqueous extracts from Lycopodium clavatum, Cetrariaislandica and Dipsacus fullonum obtained using aqueous solutions of ionic liquids by the ultrasound-assisted extraction (IL-UAE) method. Triethanolammonium salts [TEAH]+[AA]− of four amino acids of different hydrophobicity – isoleucine – Ile, methionine – Met, threonine – Thr and arginine – Arg
