Powder detergent for washing fabrics

 

(57) Abstract:

The invention relates to the production of synthetic detergents). Can be used for washing textiles from cotton, linen, silk, wool and synthetic fabrics both in the home and communal laundries. The aim of the invention is to increase detergency SMS. The aim is achieved in that the detergent containing Las sodium, nonionic surfactant, sodium tripolyphosphate, perfume perfume and sulfonate sodium, additionally contains nitrobenzenesulfonate sodium, metasilicate sodium, soda ash, carboxymethyl cellulose in the following ratio, wt.%: Las sodium 10-18; neinogennye surfactant is 0.9 to 3.0; sodium tripolyphosphate - 15-35; metasilicate sodium - 1,6-5,0; soda ash - 12-166; carboxymethylcellulose - 0,6-1,2; perfumes and perfume - 0,1-0,2; nitrobenzenesulfonate sodium - 0.5 to 1.5; sodium sulfate to 100. The application of the composition will increase the ability of powdered detergent. table 1.

The invention relates to the production of synthetic detergents (With whom such tissues as in everyday life, and in communal laundries.

Known detergent composition containing ethoxylated nonionic surface-active agent (surfactant), anionic (SAS) sodium salt of alkylsulfonic or alkylarylsulfonates or alkyl sulphates or mixtures thereof, sodium tripolyphosphate, sodium silicate, water, additives carboxymethylcellulose, Nagorniy sodium, perfume, optical Brightener, sodium sulphate [1]

The disadvantage of this composition is low washing capacity.

The closest to the technical nature of the claimed composition is a detergent for washing fabrics, which has the following ratio of components, wt.

Alkylbenzenesulfonic 4-30

Alkylsulfate or neinogennye surfactant 1-6

Sodium tripolyphosphate 15-35

Glass liquid sodium 1-4

Phosphoric acid is 0.5-5

Perfume perfume 0,1-0,2

Optical Brightener of 0.2-0.3

The sodium sulfate To 100

However, the composition does not have a sufficiently high cleaning ability.

The aim of the invention is to increase the detergency of the detergent.

The aim is achieved in that the detergent for washing fabrics, containing Latushko and sodium sulfate, additionally contains nitrobenzenesulfonate sodium, metasilicate sodium, soda ash, carboxymethyl cellulose in the following ratio, wt.

Las sodium 10-18

Nonionic surfactant of 0.9 to 3.0

Sodium tripolyphosphate 15-35

Metasilicate sodium 1,6-5,0

Soda ash 12-16

Carboxymethylcellulose 0,6-1,2

Perfume perfume 0,1-0,2

Nitrobenzenesulfonate sodium 0.5 to 1.5

The sodium sulfate To 100

Tested detergent with different content components.

The washing ability of the compositions is determined by the standard method on artificially contaminated fabrics: silk, wool and cotton.

Washing is carried out in a laboratory washing machine type Launderer" when the solution concentration 5 g/l, bath temperature 50oC, water hardness 15oH. Duration of washing for 20 min, followed by double rinsing for 2 minutes

The value of detergency is expressed in the captured contaminants.

Example 1. Testing prepared detergent of the following composition (see table):

Las sodium 10

Nonionic surfactants 0,9
and 0.6

Perfume perfume 0,1

Nitrobenzenesulfonic 0,5

The sodium sulfate Else

After testing got the following results: washing capacity: silk 35,1; wool 51,9; cotton 35,8.

Example 2. Testing prepared detergent of the following composition (see table):

Sultanol 14

Sintana DC-10 1,9

Tripolyphosphate, Na 25

Metasilicate Na 3,3

Soda ash 14

Carboxymethylcellulose 0,9

Perfume perfume 0,15

Nitrobenzenesulfonate Na 1,0

The sodium sulfate Else

According to tests, the cleaning ability: silk 35,9; wool - 52,8; cotton 34,6.

Example 3. Testing prepared detergent of the following composition (see table):

Sultanol 18

Sintana DC-10 3

The Na tripolyphosphate 35

Metasilicate Ma 5

Soda ash 16

Carboxymethylcellulose 1,2

Perfume perfume 0,2

Nitrobenzenesulfonate Na 1,5

The sodium sulfate Else

According to tests, the cleaning ability: silk 36,5; wool 53,8; cotton 35,2.

The test results illustrating the effect of the claimed composition on the ability shown in the table.

As VI is/BR> Cintanya DC-10 0,9-3

The Na tripolyphosphate 15-35

Metasilicate Na 1,6-5

Soda ash 12-16

Carboxymethylcellulose 0,6-1,2

Perfume is 0,1-0,2

Nitrobenzenesulfonate of 0.5-1.5

Sodium sulfate To 100

we offer cleanser has the ability, exceeding the ability of a known drug (example 44).

Change the content of the components above or below the proposed limits (examples 4, 8, 9, 13, 14, 18, 19, 23, 24, 29, 33, 34, 38, 39, 43) leads to decrease in detergency.

Example 44 characterizes the properties of the detergent of the prototype.

The detergent according to the invention provides high ability when washing all types of fabrics.

Technology of preparation of the proposed tools can be implemented on existing manufacturing equipment and domestic raw materials.

Powder detergent for washing fabrics, containing Las, nonionic surfactant, sodium tripolyphosphate, perfume perfume and sodium sulfate, characterized in that it additionally contains metasilicate sodium, soda ash, carboxymethylcellulose and Latrobe the Nonionic surface-active substance sintana, sintimid of 0.9 to 3.0

Sodium tripolyphosphate 15 35

Metasilicate sodium 1,5 5,0

Soda ash 12 16

Carboxymethylcellulose 0,6 1,2

Perfume perfume 0,1 0,2

Nitrobenzenesulfonate sodium 0,5 1,5
