Problems solved by technology

However, parabens have the disadvantage that the use concentration range is limited due to high skin irritation and low safety. Therefore, in cosmetics, the use concentration of parabens is limited to less than 1%.
In addition, the number of people allergic to parabens has increased in recent years, and the demand for paraben-free cosmetics has increased

Synthetic example 1

[0065] By reacting 3.0 g of hexanol and 2.1 g of epichlorohydrin at 80° C. for 4 hours to obtain hexyl glycidyl ether as an intermediate, hydrolyzing the obtained hexyl glycidyl ether to obtain monohexyl glycidyl ether containing The product 2.7g.

Synthetic example 2

[0067] After obtaining cyclohexyl glycidyl ether as an intermediate by reacting 3.2 g of cyclohexanol and 2.1 g of epichlorohydrin at 80° C. for 4 hours, hydrolyzing the obtained cyclohexyl glycidyl ether to obtain The product of cyclohexyl glyceryl ether 2.7g.

[0068]

[0069] 2.7 g of the monohexylglyceryl ether-containing product and the monocyclohexylglyceryl ether-containing product produced in Synthesis Example 1 and Synthesis Example 2 were respectively taken into a flask, and the pressure was reduced by a vacuum pump to the glyceryl ether-containing product. 100 parts by mass of water vapor at a flow rate of 3 parts by mass / h was added, and the deodorization treatment was carried out by contacting water vapor at 110°C and 4kPa for the time indicated in Table 1 or Table 2, respectively. Deodorizing treatment. It should be noted that the treatment time of 0 minutes means that deodorization treatment is not performed.

Abstract

The present invention provides: a production method that is for a glyceryl ether-containing composition and that comprises a deodorization step for bringing a glyceryl ether-containing product selected from monohexyl glyceryl ether-containing products, monocyclohexyl glyceryl ether-containing products, and mixtures thereof into contact with water vapor in an environment having a reduced pressure of 0.10-10 kPa for 60-600 minutes, and an addition step for adding 0.05-0.30 parts by mass of an antioxidant containing d-alpha-tocopherol to 100 parts by mass of the glyceryl ether-containing product; and a glyceryl ether-containing composition having specific amounts of a specific glyceryl ether and an antioxidant containing d-alpha-tocopherol.

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...
