Description

A kind of composite laundry liquid and preparation method thereof

technical field

The invention relates to a compound laundry liquid and a preparation method thereof, in particular to a compound laundry liquid of cations and various anions and nonionic surfactants and a preparation method thereof, belonging to the field of daily chemicals.

Background technique

With the development of Chinese society, environmental problems have become one of the problems our country is facing. Laundry powder has a long history, and it still occupies an important position in China's daily chemical market. The energy consumption and raw material consumption in the production process of washing powder are higher than those of laundry detergent, and the production process is more complicated. However, laundry detergent has the advantages of simple production process, low energy consumption, and no fillers. Its production process is harmful to the environment. friendly.

Most anionic surfaces in the market today use fatty alcohol polyoxyethylene ether sodium sulfate (AES). For example, the anionic surfactant used in patents CN 103194362, CN 103215142, and CN 103320237 is AES; and AES will produce Carcinogen dioxin, and there will be residues in AES products. Although the concentration reaches the national standard, the dioxin substance is very stable, has a high melting point, is extremely difficult to dissolve in water, and can be dissolved in most organic solvents. It is colorless Odorless fat-soluble substances accumulate in the body and are very difficult to excrete from the body, causing serious harm to the human body.

Composite surfactants have more comprehensive functions than single surfactants, and the composite surfactants have synergistic and complementary effects. With simple and easy-to-obtain raw materials, laundry detergent that achieves good decontamination effect and fabric softness through compounding technology is the development direction of the future washing industry. Therefore need a kind of laundry detergent of environmental protection, easily degradable, renewable, human nature on the market.

At present, compared with washing powder, laundry detergent has obvious disadvantages in detergency. Now there are a large number of special laundry detergent products on the market (for example: special laundry detergent for oil stains (Blue Moon laundry detergent), soft laundry detergent (Willow) laundry detergent), high-efficiency bactericidal laundry detergent (Miao Butler antibacterial laundry detergent), etc.). From the side, it reflects a question, why is there no comprehensive laundry detergent that can soften, sterilize and remove oil stains? This may be difficult in terms of technical preparation or formulation. Most of the surfactants with bactericidal effect are cationic surfactants or amphoteric surfactants, and the ones with strong detergency are anionic surfactants. However, when anionic and cationic surfactants are mixed together, due to the interaction between ionic bonds between molecules, Anionic and cationic surfactant molecules will be tightly combined, so that the detergency and bactericidal effect are not as good as single surfactant formula laundry detergent. In the laundry detergent research industry, how to develop a comprehensive laundry detergent is a difficult problem.

The performance of the compound laundry liquid that above-mentioned each embodiment gained is tested:

(1) Stability evaluation of compound laundry detergent

In order to verify the stability of the composite laundry detergent of the present invention, the composite laundry detergents obtained in Example 1, Example 2, and Example 3 were placed in environments where the ambient temperature was 4°C, 20°C, and 40°C to stabilize their properties. Test and cold cycle test, stability test and cold cycle test results are shown in the table below:

project Example 1 Example 2 Example 3 4°C Stability Test normal normal normal Stability test at 20°C normal normal normal Stability test at 40°C normal normal normal cold cycle test normal normal normal

Stability test conditions at 4°C: place it in a 4°C incubator for one week, and observe the abnormal appearance;

Stability test conditions at 20°C: place it in a 4°C incubator for three months, and observe the abnormal appearance;

Stability test conditions at 40°C: place it in a 40°C incubator for one week, and observe the abnormal appearance;

Cold cycle test: Place in a thermostat at -10°C for 24 hours, then transfer to a room temperature environment and return to room temperature for three cycles, and observe the abnormal appearance.

It can be seen from the test results in the above table that the composite laundry liquid obtained in the above-mentioned Examples 1-3 has good stability.

(2) Foam performance test of compound laundry detergent:

According to GB/T13173-2008 Detergent Foaming Ability Determination Method (Ross-Miles method), test the foaming ability of the compound laundry liquid obtained in Examples 1 to 3 of the present invention, use the initial foam height and the foam height after 5 minutes Indicates that the unit is mm, and the test results are shown in the table below:

name Initial foam (mm) Foam after 5min (mm) Example 1 135 35 Example 2 140 32 Example 3 130 34

As can be seen from the above table, the initial foam height of the composite laundry liquid obtained in Examples 1 to 3 is 130 to 140 mm, and after 5 min, the foam height drops to 32 to 35 mm, thus showing the composite laundry detergent of the present invention. The foaming ability of the laundry detergent is strong, and the foam breaking speed of the system is fast. The decontamination of laundry detergent includes two processes. First, it wraps the stains such as oil stains or particles, takes them away from the clothes in the form of foam, and dissolves them into the laundry water; second, there are two main aspects to the foam breaking effect. One is to dissolve the stains into the laundry In the water body, part of the surfactant is released to improve the washing effect, but it is convenient for subsequent washing, reducing the number of washing times and saving water consumption. Therefore from the analysis of the foam performance test, the decontamination effect of the compound laundry liquid of the present invention is better.

(3) Degreasing effect test of compound laundry detergent

In order to determine the degreasing performance of the composite laundry detergent obtained in Examples 1-3, a white towel was divided into 4 small pieces, treated with oil stains (the oil stains came from the restaurant) and dried in the air, one of which was used as a control group; the other 3 block as the experimental group.

Weigh 5 g of the composite laundry detergent obtained in Examples 1 to 3 and dissolve them in a beaker containing 1000 ml of tap water (the capacity of the beaker is 2000 ml), and put 3 pieces of oil-stained cloth treated with oil as an experimental group into a 1000-ml beaker containing In the tap water of the composite laundry detergent obtained in Examples 1 to 3, stir gently with a glass rod for 5 minutes;

Put the oil-stained cloth treated with oil as a control group into 1000ml of tap water without compound laundry detergent, and gently stir it with a glass rod for 5 minutes;

Observe the variation of the oil stains of the oil-stained cloth used by the experimental group and the control group in the stirring process, and the results are shown in the following table:

It can be seen from the above table that the appearance of the water body of the composite laundry liquid obtained in Examples 1 to 3 changes color rapidly, while the water body without the composite laundry liquid obtained in Examples 1 to 3 has no obvious change in the appearance of the water body during the stirring process . The essence of surfactant degreasing is to wrap the oil stains to form micelles and disperse them in water, so as to remove the stains on the surface of clothes and so on. Compared with anionic surfactants, nonionic surfactants have better compatibility with oil stains, can be compatible with oil stains faster, and can more easily achieve the purpose of removing oil stains. However, the solubility of nonionic surfactants in water is not as good as that of anionic surfactants. The non-ionic surfactants in the compound laundry detergent can quickly dissolve and diffuse the stains into the water body, and at the same time, the anionic surfactants in the water body can exchange part of the non-ionic surfactants from the non-ionic surfactant micelles that wrap the oil stains agent, so that the oil stains are wrapped by anionic surfactants and nonionic surfactants. Such a synergistic effect is reflected in two aspects: one is to increase the speed at which the oil stains on the clothes diffuse into the water, and the other is to increase the dispersibility of the oil stains in the water; the oil stains on the clothes can be removed faster and more efficiently. Combined with the experimental conclusions, it shows that the composite laundry detergent of the present invention has a good degreasing effect.

(4) Softness performance test of compound laundry detergent

In order to test the compliance performance of the composite laundry detergent obtained in Examples 1-3, the hardened towel in daily life is used as the experimental object, and the apparent state of the hardened towel before and after washing is compared. The specific steps are as follows:

Cut the hardened towel into 4 pieces, 1 piece is used as hardened cloth A for the control test, and 3 pieces are used as hardened cloth B for the experiment.

Weigh 3 g of the composite laundry detergent obtained in Examples 1 to 3 and dissolve them in a beaker containing 1000 ml of tap water (the capacity of the beaker is 2000 ml). In the tap water of the composite laundry detergent obtained, gently stir the hardened cloth B for 5 min with a glass rod;

Put the hardened cloth A into 1000 ml of tap water without compound laundry detergent, and gently stir the hardened cloth A with a glass rod for 5 minutes;

Then dry the hardened cloth A and hardened cloth B, and the observation results are shown in the following table:

It can be seen from the above table that the hand feel and appearance of the hardened towel added with the compound laundry detergent have obvious changes before and after washing, while the hardened towel without the compound laundry detergent has no obvious difference before and after washing. Today's clothing fabrics are almost all blended, in which the surface of the fiber is prone to static electricity, and the same charge repels each other to make the surface of the fiber not smooth, and the friction coefficient of the fiber surface is greatly increased. Fiber softening effect is directly related to surface charging. Therefore, the amount of cationic surfactant adsorbed on the fiber surface is the key to the softness performance, but the solubility of cationic surfactant in water is limited. The composite lotion of the present invention contains nonionic surfactants and amphoteric surfactants, which can greatly promote the dissolution of cations in water, thereby enabling more adsorption of cationic surfactants on the fiber surface and reducing the electrostatic effect on the fiber surface , so that the clothes have good softness. Combined with the experimental results, it has been shown that the composite laundry detergent of the present invention has a good softening effect.

To sum up, the compound laundry detergent of the present invention has low foaming, good decontamination and faster degreasing ability, and good flexibility of the clothes after washing.

The foregoing is only an example of the embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, some improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and Modifications should also be regarded as the scope of protection of the present invention.
