Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides cleaning solutions containing specific amphoteric polymers.
Sprinkle on finished product. For more details, see cationic vinyl mono!
The present invention relates to a detergent composition whose cleaning performance is significantly improved by containing a specific amphoteric polymer obtained by copolymerizing K and an anionic vinyl monomer.

Traditionally, polymers have been used as additives in detergent systems for a variety of purposes. For example, thickeners, stabilizers,
Colloidal agent, bilgoo, flexible carrier encapsulating agent, clouding agent,
Systems added to detergents as pearlizing agents, skin and hair retention agents, etc. are known. However, their use was merely to take advantage of the generally recognized properties of polymers.

However, as the present inventors investigated new applications for polymers in detergent systems, they were surprised to find that a specific polyester! The present inventors have discovered the fact that the cleaning performance of a cleaning composition can be significantly improved by coexisting 41 with a surfactant, and have completed the present invention.

That is, in the present invention, a specific amphoteric polymer obtained by copolymerizing a cationic vinyl monomer and an anionic vinyl monomer is contained in a cleaning composition. Bisexual! - The effects of polymer surfactants, such as dispersion effects, are not directly related to conventional cleaning.

It is completely different.

In other words, the amphoteric heavy metal polyester used in the original F14! - represents an anionic vinyl monomer having a polymerizable unsaturated group and a cationic vinyl monomer having a polymerizable unsaturated group from 1 to ?

1 <Test method> - A) Detergent power Add 0.1% Sudan ■ (red pigment) as an indicator to beef tallow, and wash the dish coated with 5JF on a magnetic dish (diameter 215 m) and soak it with 1iJ1ON and 201ml water. The number of plates that have been cleaned is indicated by the number of plates that have been scrubbed with a damp sponge until the tallow is no longer clean from the plates.

Mouth) Foaming power The foaming power is measured when reprinted butter is added as a stain component in a detergent solution KO 11% with a detergent concentration of O, S%. The measurement method was to add putter to a glass cylinder with a diameter of 551 mm.
Add 40 J of solution, rotate and stir for 10 minutes, and measure the groove height immediately after stopping.

→Wash a commercially available 20011j glass tip with a cleanser, etc., make sure it does not repel water, then rinse with ionized water and dry. Pour 150ml of 1% aqueous solution into a 1-inch cup and boil for 50''.

After rotating and stirring for a minute, the aqueous solution is poured.

Next, pour 200 liters of tap water into the tube and let it stand for 50 seconds, then drain the water. , Repeat this once. 4. Observe the water repellent odor when water is poured on the eye, and the finished state of the pot after leaving it for one day.

Engineering) 100 cc of rinsing detergent concentration 0.25% aqueous solution (temperature 20°C)
Pour 500 micrometers of water into a funnel, shake it a certain number of times, pour out the liquid, and measure the amount of foam. , then rinse water soap (
Pour in the liquid (temperature: 20°C), and rotate the liquid at 910 rpm.

Repeat this and find the number of times until the bubbles disappear and use it as the number of rinses.

A liquid detergent was made with the formulation in Example 1, and its detergent power and foaming power were measured. The results are shown in Table 2. From Table 2, the detergent power and foaming power were significantly increased by adding polymer. It can be seen that it increases.

A liquid detergent was prepared using the formulation of Example 2, and the results of a water splash test are shown in Table 5.
