Abstract: The problem of the present disclosure is to impart manageability and flexibility to hair after being dyed or bleached using an oxidative hair dye or a hair bleaching agent. The features for solving the problem are a first agent of an oxidative hair dye or a hair bleaching agent comprising: (A) a polyvalent carboxylic acid having no hydroxyl group or a salt thereof; (B) a surfactant including (B1) a cationic surfactant and (B2) a nonionic surfactant; (C) an oily component; and (D) an alkaline agent.

Abstract: The present invention provides a two-part hair cosmetic material having a reduced irritating smell due to ammonia. Specifically, the present invention relates to a two-part hair cosmetic material comprising a first agent containing an alkali agent and a second agent containing an oxidizing agent, wherein the first agent contains the following ingredients: (A) a polyoxyethylene alkyl ether having a polyoxyethylene chain length of 50 or more, (B) a higher alcohol, and (C) a polyoxyethylene alkyl ether having a polyoxyethylene chain length shorter than the polyoxyethylene chain length of the polyoxyethylene alkyl ether (A), and the content of a higher alcohol having 20 or more carbon atoms in the higher alcohol (B) is 1.0% by weight or less based on the weight of the first agent.

Abstract: In a system for exchanging packages on a textile machine such as a rewinder, a creel loader receives empty packages from a creel for transportation to the position of a package supporter, the package supporter is rotated about a vertical axis over 180 degrees to place full packages in a position facing the creel loader, and, after receipt of the full packages, the creel loader travels to a section of the creel in need of package exchange for transfer of the full packages to the creel. Concurrently with this process, full packages from a package stocker is mounted to the package supporter by operation of an assistant device such as a robot for next exchange of packages with the creel loader. Loss in production efficiency otherwise caused by empty travel of the loader is well avoided.
