<p><P>PROBLEM TO BE SOLVED: To provide transparent bar soap, which is highly transparent, is easy to lather, especially with hard water, has proper hardness as bar soap, has no problems of deterioration of smell by aging or swelling, is highly productive, and can be easily molded into a desired form. <P>SOLUTION: The transparent bar soap contains linear saturated fatty acid of carbon numbers of 12-18, and/or its salt (A), and substantially does not contain branched chain fatty acid salt or unsaturated fatty acid salt. It also contains one kind or two or more kinds (B) selected among nonionic surface active agent, ampholytic surface active agent, polyalcohol that is liquid at normal temperature, and saccharides, inorganic salts (C), and water (D). To the total quantity of the bar soap, content of the fatty acid of component (A) is 20-40 mass%, the mass ratio between the fatty acid of component (A) and component (B) is 30:70-45:55, content of component (C) is 0.5-5 mass%, and content of component (D) is the rest. The mass ratio between the fatty acid of the carbon number of 12 of the component (A) and the total quantity of the fatty acid of the carbon number of 16 and the carbon number of 18 is 30:70-60:40. The mass ratio between the fatty acid of the carbon number of 12 and the fatty acid of the carbon number of 14 is 20:80-80:20. Total quantity of the fatty acid of the carbon number of 12 and the fatty acid of the carbon number of 14 to the total quantity of the bar soap is 14-22 mass%. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
