Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to abrasive-containing liquid cleaning compositions useful for cleaning tableware, kitchenware, and other hard surfaces.

The use of liquid detergents as detergents for dishes, etc. has of course been known in the past, but recently liquid compositions containing abrasives have been proposed, for example, in JP-A-47-22906 and JP-A-51-5.
0909, etc. However, these products focus on their performance as cleansers, and when used diluted, they have more foaming power than so-called kitchen liquid detergents.

The drawback is that the cleaning power is significantly reduced. In addition, a liquid cleaning composition containing an abrasive agent has been proposed in JP-A-56-58597, but the composition shown in the examples has insufficient performance as a cleaning agent, and the abrasive agent is not dispersed. Thickeners have been used to achieve this, but the stability of the compositions is not always satisfactory.

The present inventors have developed a polishing agent that has sufficient cleaning performance as a kitchen cleaner, has a special cleaning effect using an abrasive (particularly greatly improves the finish of tableware, etc.), and has excellent storage stability. As a result of intensive research in order to provide an abrasive-containing liquid cleaning composition, we have developed an abrasive-containing liquid composition with excellent storage stability that can achieve these objectives by containing the following five specific components in specific amounts as essential components. A cleaning composition was discovered and the present invention was completed. That is, the present invention provides an abrasive-containing liquid cleaning composition characterized by containing the following five components (a) to (θ) as essential components.

(a) polyoxyethylene alkyl ether sulfate,
One or more anionic surfactants selected from the group consisting of alkylbenzene sulfonates, α-olefin sulfonates, and alkanesulfonates 10 to 40
% (b) 0.5 to 1% by weight of secondary alcohol ethoxylate represented by the following general formula (I) (in the formula,
m=1~14, 1~1~14, m+ m=8-1
5, p is 2 to 10 on average) (c) Tertiary amine oxide represented by the following general formula (g)) 0.1 to 5 weight coefficient 2 Rnie N-40 (in the formula, R □ represents an alkyl or alkenyl group having 10 to 18 carbon atoms % R21R5 represents an alkyl group having 1 to 2 carbon atoms) (a) Water-soluble inorganic magnesium salt 0.1 to 5 weight ratio (
e) Water-insoluble abrasive 1 to 20% by weight In general, methods for dispersing abrasives in liquid cleansers include a method of imparting structural viscosity with an organic or inorganic thickener, and a method of imparting structural viscosity using an active agent as the main component. There are known methods for giving

These systems containing medium thickeners tend to lose their structural viscosity when the active agent concentration increases, and when the amount of thickener added increases, undesirable viscosity behavior such as stringiness or gel-like behavior may occur. There is also the problem of deterioration over time. On the other hand, activator thickening systems are relatively susceptible to temperature changes and have problems with stability, particularly at high temperatures.

However, according to the composition system of the present invention, which is made of a combination of the above-mentioned specific activators, etc., a system can be obtained that has appropriate structural viscosity, has sufficient stability at high temperatures, and is not affected by temperature changes. It was discovered that Thus, the composition system of the present invention has sufficient cleaning performance as a kitchen cleaner.

The anionic surfactant which is the component (a) of the composition of the present invention is a polyoxyethylene alkyl ether sulfate represented by the following general formula (2) R, -0-(C!H2O
H2O1, So, M ωθ (in the formula, R1 has a carbon number of 8 to 1
8 represents an alkyl group or an alkenyl group, M represents an alkali metal, ammonium or alkanolamine, and n
id 1 to 5 on average), and an alkylbenzene sulfonate represented by the following general formula (in the formula, R2 represents an alkyl group having 1 to 16 carbon atoms),
λhe represents an alkali metal, ammonium or alkanolamine) is preferred.

Further, the water-soluble inorganic magnesium salt which is the component (d) of the composition of the present invention is magnesium sulfate.

Magnesium chloride, magnesium nitrate, potassium magnesium chloride sulfate, magnesium bromide.

Magnesium iodide, magnesium ammonium sulfate,
One or more magnesium salts selected from the group consisting of potassium magnesium sulfate and sodium magnesium sulfate are preferred. The amount of the anionic active agent (a) used in the present invention is 10 to 400. 40 parts by weight.

If it is less than 10% by weight, performance such as detergency becomes insufficient, while if it exceeds 40% by weight, the viscosity increases rapidly and the high temperature stability decreases. The secondary alcohol ethquinate represented by the formula (I) as component (b) is 0.5 to 10% by weight, preferably 1 to 5% by weight. If the amount added is outside this range, stability and performance will be insufficient. The tertiary amine oxide represented by the formula (II) of the component (Q) is 0
．． It is blended in an amount of 1 to 5% by weight. Outside this range, stability is decreased and viscosity increases rapidly, which is not preferable.

The water-soluble inorganic magnesium salt of component (d) has a weight ratio of 0.1 to 5. If the amount is too small, stability will decrease, while if it is too large, performance will decrease. Component (e) water-insoluble abrasives include silicon dioxide, aluminum oxide, magnesium oxide, titanium oxide, aluminosilicate, carbonized carbon, calcium carbonate, calcium phosphate, and silicon dioxide, which are commonly used as water-insoluble abrasives. Natural crushed products such as chromium, emery, silica 9 quartz sand, dolomite, sand, shells, and seismic powder.

Plastic powders such as polystyrene and polyacrylate can be used. The blending amount is 1 to 25 parts by weight, preferably 5 to 20 parts by weight, per 100 parts by weight of the composition.

The target stains to which the abrasive-containing liquid detergent of the present invention is applied are those that are easy to remove as a cleanser but difficult to remove as a kitchen detergent, so a blending amount that can impart appropriate abrasiveness is selected. Ru.

If the amount is too low, the positive effect of the abrasive will not be obtained, while if it is too high, there is a fear that it will have an effect on the object (deviation, etc.). The particle size of the abrasive may be coarse, but it is preferably 1 to 150 microns in consideration of damage to the object.

In carrying out the present invention, anionic surfactants, nonionic surfactants, and cationic surfactants other than those specified in the present invention may be used as long as they do not impair the intended effects of the present invention. Amphoteric surfactants, fragrances, dyes, antibacterial agents, solubilizers, etc. can be added to the composition. In addition, organic and inorganic thickeners such as hydroxyethyl cellulose, bentonite, and xanthan gum may be blended to reinforce the structural viscosity or as a viscosity modifier within a range that does not impair the effects of the present invention.

The abrasive-containing liquid cleaning composition of the present invention does not separate even after long-term storage, is stable, is not affected by external temperature changes, and has excellent cleaning power, foaming power, and appropriate polishing power. have.

Test Method> (Cleaning Power) 0.1% of Sudan ■ (red pigment) was added as an indicator to beef tallow, and this 52 was applied to a porcelain dish (diameter 25 cm) to prepare detergent 102. The number of plates that have been scrubbed with a sponge soaked in water 202 until the tallow can no longer be removed is shown as the number of plates that have been washed.

(Foaming power) The foaming power is measured when 0.1 g of commercially available butter is added as a stain ingredient to a detergent solution with a detergent strength of 0.5 g. The measurement method is to place 40 cc of the above detergent solution to which butter has been added into a glass cylinder with a diameter of 5 m, rotate and stir for 10 minutes, and measure the foam height immediately after stopping.
