Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on the granular detergent set IJ!, which has both excellent cleaning power for stains on clothes and a softening effect. relating to things.

A fabric softening detergent that cleans clothes at home and at the same time imparts flexibility [7] A detergent composition in which a powdery cationic surfactant is added to a granular detergent containing an anionic surfactant as a main component is available.[41] H41~ has been proposed (JP-A-5'5-106299, JP-A-5 Fi-1154)
99, JP-A-57-1373961゜However, such cleaning agents have low cleaning power because the anionic surfactant and cationic surfactant in the detergent react in the washing liquid to form a complex. There was a problem that it caused a tinge.

In order to eliminate such drawbacks, the inventors of the tree added 4τ;
It was discovered that the first objective could be achieved by blending charcoal f'fy with sodium, and based on this knowledge, the present invention was completed.

That is, the granular detergent of the present invention, 1115Q product, is (a)
An alkylbenzenesulfonic acid salt having an alkyl group having a carbon number of In to 18 3 = 40 '+@L (represented by (b) F general formula rl), a cationic surfactant and (c) sodium percarbonate. It is characterized by containing.

The detergent phase composition of the present invention may further contain surfactants, detergent buildup and other additives. As a surfactant, an anionic surfactant such as α-olefin sulfonate of Teke CIO~2o, alkyl ethoxysilium Ga, T-alkyl sulfate, etc. Examples include nonionic surfactants such as alcohol conitocylates, and amphoteric surface active agents such as alkyl betaines.

By combining F's cationic surfactant 1 and argylbenzene sulfonate, and further adding sodium percarbonate, it is possible to impart flexibility at the same time as cleaning without causing a decrease in cleaning power. .

EXAMPLE In addition to the ingredients (by weight) shown in Table 1, a detergent composition containing the following ingredients was prepared and tested for cleaning power and flexibility imparting effect.

(1) Testing of detergency (1) Preparation of artificial soiled cloth Clay containing crystalline minerals such as kaolinite and noz-mikinilite as its main ingredients was dried at 200°C for 301 hours.
After that, the average particle size of 1 μm was crushed using Uta, and it was used as No + 1 Purification Dirt and 2.

After dissolving 3.52 g of gelatin in 950 cc of water at about 40°C, it was heated to 0.257 g using a Polytron (Switzerland KTN FA4AT I OA barb 1), which is a powerful emulsifying and dispersing machine.

After soaking the cleaning cloth (cotton cloth 60 ti'f specified by Japan Oil Chemists' Association), use Rubber iJ! The water was squeezed out using two rolls to even out the dirt on the needles. This soiled cloth was dried at 1.05° C. for 30 minutes, and then both sides of the soiled cloth were rubbed 25 times from side to side. This was cut into 5 cm x 5 tyn K pieces, and one piece of JFl Kawada paper with an anti-ilt ratio of 42±2% was placed on a dirty cloth. The soil composition of the artificially soiled cloth thus determined is as shown in Table 2. Added organic dirt 5 Q III? shown in 2 rocks.

The cleaning power was evaluated based on the average value of 1 ゜ sample of artificially soiled cloth. 80 ri x 2 pieces cotton bleached cloth 5'Of' x 4
A 1-piece knitted cloth 85mm × 4 pieces of test cloth were washed with the above granular detergent and tap water at 60°C for 15 minutes.
After washing for 1 minute, the test fabric was pretreated with IM for 3 minutes each time using tap water at 6 ()°C. 21 The test fabric was then placed in a jet-type household washing machine and washed with the granular detergent described above. and each additive, using item 1i component 1 and tap water at 25°C,

The procedure of soaking in water for 3 minutes and then dehydrating for 1 minute was repeated twice. After that, the test fabric was air-dried for 24 hours, and then the air-dried test fabric was subjected to condition F at 25℃ and 65℃. Conditioned.

A cotton towel was removed from the test cloth obtained in this way, and five judges judged the feel of it.
The softening effect of the additive composition was evaluated from the average of five people. In addition, this texture was created using the same procedure as described in 2 except that no additive composition was used, and the feel of the cotton towel was set to zero. There are three lines.
