摘要
PROBLEM TO BE SOLVED: To provide safe and slightly soluble amino acids microparticles readily formulated in a cosmetic while maintaining properties essential to the slightly soluble amino acids without modifying the slightly soluble amino acids, easily compatible with skin, and further having excellent absorbency, to provide a method for producing the microparticles, to further provide a cosmetic having excellent skin absorbency and a transparence feeling at use concentration of the saturated cencentration or above, and to provide a food additive.;SOLUTION: The method for producing the slightly soluble amino acids microparticles is characterized by physically finely dividing the slightly soluble amino acids having ≤0.5 g/100 g solubility in water at 20°C according to a wet pulverizing method, and regulating the average particle diameter which is a particle diameter where the cumulative value of frequency from the lower limit or the upper limit becomes 50% in a particle diameter distribution curve measured by using a laser diffraction/scattering type apparatus for measuring the particle size distribution to ≤1.0 μm.;COPYRIGHT: (C)2010,JPO&INPIT
