Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a detergent composition with excellent detergency and foaming power, and its features are as described below.
& e b a e 3 ingredients are contained in a specific blending ratio. As is well known, α-sulfo fatty acid ester salt has sufficient cleaning power as an active ingredient in laundry detergents, Moreover, it has the advantage of giving the cloth being washed a good texture, but on the other hand, it has the disadvantage of being inferior in foaming power compared to monolinear alkylbenzene sulfonates or α-olefin sulfonates. The invention combines α-sulfo fatty acid ester jJ[K olefin sulfonate and alkylbenzene sulfonate - these three components are used as the active ingredients of a detergent, thereby producing the above-mentioned properties of α-sulfo fatty acid ester salt. The cleaning composition of the present invention, which aims to provide a cleaning composition that eliminates the drawbacks, has as its active ingredient one component: formula is a C1-C9 alkyl group, and R is a C1-C9 alkyl group.
C3 alkyl group, y represents an alkali metal or alkaline earth metal. Three components of the alkylbenzene sulfonate salts are used: metal salts (where R'' represents C, ~C trout alkyl group, and M represents an alkali metal or alkaline earth metal). The blending ratio of the three components must be within the following specific range.
[This shows the triangular coordinates of (component a), olefin sulfonate (component b), and alkylbenzene sulfonate (component @). According to the present invention, the three components of &ebme, which are active ingredients, are shown in the attached drawings. Point A (a component 50 vt%, 1b component 80 vt%, 1C component 20 vt%) Point B (a component 10 wt%, b component 70 vt%, C component 20 vt%) Point C (a component 10 wt%, b component 35 vt%.

C component 55 vt%) Point D (a component 30 vt%, b component 1 !i wt%,
It must be contained in the cleaning composition at a rate within the range surrounded by the five points: point E (component A: 80 vt%, component B: 15 wt%, component C: 35 vt%). As long as this condition is observed, a detergent composition with excellent foaming power can be obtained. In the cleaning composition of the present invention, the total amount of the above three components is usually 10 to 10.
It is allowed to be in the range of 40 vt%.

The detergent composition of the present invention may contain conventional detergent additives that are conventionally mixed in common detergent compositions in usual amounts. Acid #11 aluminosilicate, tritetraphosphate,
Inorganic gilders such as xerophosphates, ornophosphates, carbonates, sulfates, maleates, salts of copolymers of maleic acid and olefins, citrates, oxydiacetates,
It includes organic building blocks such as oxydisuccinate and nitrilotriacetate, organic chelating agents such as EDTA, anti-caking agents, fluorescent brighteners, stone age, enzymes and writing materials.

Next, the structure and effects of the present invention will be explained in more detail by showing examples. In each example, various cleaning compositions in which the type and/or amount of surfactant used as an active ingredient are changed. The foaming power and cleaning power of each cleaning composition were examined. The foaming power and cleaning power were evaluated as follows.
