Description

technical field

[0001] The present invention relates to a method for producing a glyceryl ether-containing composition capable of sufficiently preventing oxidative deterioration during storage, time-dependent decomposition, and generation of bad odors and maintaining quality for a long period of time, and to a glyceryl ether-containing composition. Background technique

[0002] In cosmetics, detergents, etc., antimicrobial agents are generally used for the purpose of preservation and the like. As such antibacterial agents, parabens are most commonly used. However, paraben has the disadvantage that the use concentration range is limited due to high skin irritation and low safety. Therefore, in cosmetics, the use concentration of paraben is limited to less than 1%. In addition, in recent years, the number of people who have allergic reactions to parabens has increased, and the demand for cosmetics that do not contain parabens has increased.

[0003] Therefore, it is known th...
