Embodiment approach

[0105] A preferred embodiment of feature F is as follows:

[0106] Based on 100 parts by mass of the total amount of component (a) contained in the detergent composition of the present invention,

[0107] (F-1) Proportion of one or more lauric acid salts: preferably 20 to 75 parts by mass, and more preferably 30 to 75 parts by mass;

[0108] (F-2) Proportion of one or more myristates: preferably 10 to 45 parts by mass, and more preferably 10 to 35 parts by mass;

[0109] (F-3) The ratio of the total amount of one or more palmitates and one or more oleates: preferably 5 parts by mass to 50 parts by mass, and more preferably 5 parts by mass to 40 parts by mass; And (F-4) The ratio of the total amount of fatty acid salts other than the above: preferably 0 to 8 parts by mass, and more preferably 0 to 5 parts by mass.

[0110] (b) Sophorolipid (SL)

[0111] SL of component (b) used in the detergent composition of the present invention is a glycolipid composed of hydroxy fatty ...

preparation example 1

[0162] Reference Preparation Example 1: Preparation of Sophorolipids

[0163] A product containing 10 g of aqueous glucose (manufactured by Nihon Shokuhin Kako Co., Ltd., product name: Nisshoku Gansui Kessho Budoto), 10 g of peptone (manufactured by Oriental Yeast Co., Ltd., product name: Peptone CB90M) and 5 g of yeast was used per liter A liquid medium of an extract (manufactured by Asahi Food & Healthcare Co., Ltd., product name: Meast Powder N) was used as a medium. Candida bombicola ATCC 22214 was cultured in the medium for two days while shaking at 30°C. Use it as a pre-culture solution.

[0164] Based on the total amount of the medium, the preculture solution was inoculated into the main medium (3 L) in a 5 liter fermenter in an amount of 4%, and then cultured at 30° C. for 6 days at an aeration rate of 0.6 vvm for fermentation. The main medium contains 100 g of aqueous glucose, 50 g of palm olein (produced by NOF Corporation, product name: Palmary 2000), 50 g of ol...

preparation example 2

[0166] Reference Preparation Example 2: Preparation of Acid Type SL

[0167] The SL obtained in the above Reference Production Example 1 (with a water content of about 50% by mass) was adjusted to pH 14 by adding an aqueous sodium hydroxide solution, and the resulting mixture was treated at 80° C. for 2 hours to undergo hydrolysis (alkaline hydrolysis). Subsequently, the hydrolyzate was returned to room temperature, and then adjusted to pH 11 by using sulfuric acid (9.8M aqueous solution). The resulting insoluble matter was removed by filtration to obtain a filtrate as an SL-containing aqueous solution. The SL-containing aqueous solution contained acid-type SL in an amount of 30% by mass.

Abstract

The present invention provides a detergent composition that exhibits excellent storage stability, and especially storage stability at low temperatures, and a detergent composition which can be discharged favorably from a dispenser. This detergent composition contains (a) a fatty acid salt and (b) a sophorose lipid, and is characterized in that: the proportion of component (a) contained in 100 mass% of the detergent composition is 4-18 mass%; relative to a total of 100 parts by mass of component (a), the proportion of fatty acid salts having 12 or fewer carbon atoms is 15 parts by mass or moreand the proportion of fatty acid salts having 16 or more carbon atoms is 60 parts by mass or less; the proportion of acid type sophorose lipid is 80 mass% or more relative to a total of 100 mass% of component (b); and the proportion of component (b) is 5-80 parts by mass relative to a total of 100 parts by mass of component (a).

Description

technical field [0001] This application claims priority from the specification of Japanese Patent Application No. 2017-043340 filed on March 7, 2017 and International Application No. PCT / JP2017 / 041133 filed on November 15, 2017, the entire disclosure of which is adopted This specification is incorporated by reference. [0002] The present invention relates to cleaning agent compositions having good storage stability, especially at low temperatures. The present invention also relates to a cleaning composition that can be dispensed smoothly from a dispenser. The present invention also relates to cleanser compositions exhibiting good foaming properties and foam stability. The present invention also relates to cleanser compositions which not only exhibit good foaming and foam firmness, but also ensure good foam quality and pleasant touch, and impart a sense of comfort during washing. Background technique [0003] Detergents are used for washing the body (eg, hair and body, in...
