manufacture example 1

[0090] Add 1615.0 g (12.35 moles) of 1-octanol (KALCOL 0898, manufactured by Kao Corporation) and 6.9 g (0.12 moles) of potassium hydroxide to the autoclave, dehydrate at 110 °C and 13.3 kPa, then at 120 °C, 1434 g (24.69 mol) of propylene oxide was injected at 0.3 MPa to carry out the addition reaction.

[0091] After the reaction was completed, aging was carried out at the same reaction temperature for 6 hours, and then cooled to 80°C.

[0092] As a post-treatment, 55 g of a synthetic adsorbent (KYOWORD600S, Kyowa Chemical Industry Co., Ltd.) was added to the obtained reaction composition, and the catalyst was removed by filtration after treatment at 4.0 kPa for 1 hour. The 1-octanol content of the obtained filtrate was quantitatively determined by gas chromatography to be 9000 ppm.

[0093] Next, 1-octanol was removed by distillation with respect to 1,000 g of the obtained filtrate under conditions of 130° C. and 1.3 kPa. Then, 100 g of steam was blown in under the condit...

manufacture example 2

[0096] In the same manner as in Production Example 1, alkylene glycol ethers 2 to 12 shown in Table 1 (product of the present invention) and Table 2 (comparative product) were obtained. The alkylene glycol ethers 2 to 5 were purified in the same manner as in Production Example 1, and the alkylene glycol ethers 6 to 12 were only subjected to the removal of the catalyst by filtration as shown in Production Example 1, and no purification by distillation was performed. The amount of raw material alcohol in the obtained alkylene glycol ether was quantitatively measured by gas chromatography.

Embodiment 1

[0108] Using the alkylene glycol ethers 1 to 12 and surfactants shown in Tables 1 and 2, detergent compositions were prepared according to the usual method, and the viscosity, foaming property and odor were evaluated by the following methods.

[0109] The measurement conditions of the viscosity are as follows. The results are shown in Tables 3 and 4.

[0114] (2) Foaming test and odor test

[0115] 1 ml of each cleansing composition described in Tables 3 and 4 was dropped on the palm, and 10 specialists evaluated the foaming property and odor after cleaning hands and arms according to the following evaluation criteria.

Abstract

Disclosed is a low-odor thickening / foam boosting agent having foam boosting / thickening properties. Also disclosed is a cleaning composition containing such a thickening / foam boosting agent. Specifically disclosed is a thickening / foam boosting agent composed of the following component (A). (A) A compound represented by the following general formula (1). R<1>O-(PO)n / (EO)m-R<2> (1) (In the formula, R<1> represents a linear alkyl group having 8 to 10 carbon atoms or an alkenyl group; PO represents a propyleneoxy group; EO represents an ethyleneoxy group; the average added mole number n is a number of 1.5 to 3.0; the average added mole number m is a number of 0 to 1.0; and R<2> represents a hydrogen atom or a methyl group.) The alcohol content, which is represented by the above formula (1) with n being 0, m being 0 and R<2> being a hydrogen atom, is not more than 3000 ppm. Also specifically disclosed is a cleaning composition containing the above component (A) and a surface active agent (B).

Description

technical field [0001] The present invention relates to a low-odor thickening and foaming agent for a detergent base containing alcohol propylene oxide and / or ethylene oxide adduct (alkylene glycol ether) and having foaming and thickening properties, and Cleansing composition for the body, such as dishwashing agent, shampoo, body shampoo, etc. using the thickening and foaming agent, which requires rich foaming. Background technique [0002] Detergent compositions require various properties such as emulsifying power, solubilizing power and detergency of stain components such as oil. Among them, cleaning agents for hard surfaces such as tableware cleaners used by humans, and body cleaners such as shampoos and body shampoos are mainly used. Unlike industrial cleaning agents, rich foaming and handling are required. When the base agent is odorless, and the feeling of use such as moderate viscosity is improved. On the other hand, in a detergent for industrial use, less foaming i...
