Description

A neutral toilet cleaner

technical field

The invention relates to a detergent, in particular to a neutral toilet cleaning liquid.

Background technique

With the improvement of living standards, consumers are more and more concerned about the safety and mildness of toilet cleaning products. The toilet cleaners currently on the market are basically composed of strong acids, surfactants, and thickeners. The strong acid in the toilet cleaner can quickly break down the dirt components such as urine scale, soap scum and rust stains in the bathroom and toilet. Although the detergency is very strong, due to the addition of strong acid, when cleaning the porcelain surface, it will also be highly corrosive to hands and porcelain surfaces, and the scope of use is also narrow, so it cannot be used for cleaning metal wash basins, bathtubs, etc.

Contents of the invention

The object of the present invention is to provide a neutral toilet cleaning liquid with strong detergency and non-corrosiveness.

The object of the present invention is achieved through the following technical scheme: a kind of neutral toilet cleaning liquid, comprises the component of following mass percentage:

Surfactant 0.5%-30%

Thickener 0.1%-5%

Chelating Auxiliary 0.05%-10%

Solvent 2%-20%

Preservatives 0.03-0.2%

Flavor 0%-1%

Pigment 0-0.1%

pH adjuster 0~1%

Preservatives 0~0.1%

water balance.

In the present invention, the surfactant is one or a mixture of nonionic surfactants and anionic surfactants. The nonionic surfactant is fatty alcohol polyoxyethylene ether or alkyl glucoside. Wherein, the fatty alcohol carbon chain length of the fatty alcohol polyoxyethylene ether is 8C-16C, the carbon chain structure is straight chain or branched chain, and the EO number is 3-10. The alkyl carbon chain length of the alkyl glycoside is 8C-16C. The anionic surfactant is linear alkylbenzene sulfonate, alpha olefin sulfonate, fatty alcohol polyoxyethylene ether sulfate, alkyl diphenyl oxide disulfonate, secondary alkyl sulfonate , ethoxylated fatty acid methyl ester sulfonate, alcohol ether carboxylate and fatty acid methyl ester sulfonate, or a mixture of two or more. Wherein, the alkyl carbon chain length of the linear alkylbenzene sulfonate is 12C-14C. The fatty alcohol carbon chain length of the fatty alcohol polyoxyethylene ether sulfate is 8C-16C. The fatty alcohol carbon chain length of the ethoxylated fatty acid methyl ester sulfonate is 12C-18C. The fatty alcohol carbon chain length of the fatty acid methyl ester sulfonate is 12C-18C.

The chelating aid is one or a mixture of sodium gluconate, sodium citrate, and edetate. The chelating agent chelates calcium and magnesium ions and metal ions in the dirt, thereby exfoliating and separating the dirt.

The thickener is one or a mixture of two or more of cellulose derivatives, guar gum or its derivatives, and xanthan gum or its derivatives.

The solvent is one or a mixture of 2-methyl-2,4-pentanediol, propylene glycol butyl ether, dipropylene glycol butyl ether, and tripropylene glycol butyl ether.

The pH regulator is citric acid or sodium hydroxide.

Compared with the prior art, the present invention has the following advantages:

(1) The toilet cleaner provided by the present invention is a neutral product with strong decontamination ability, and can remove soap scum and urine stains very easily and conveniently.

The invention does not contain strong acid, has no corrosiveness, has a pH value of 4-9, is close to human skin, does not cause harm, does not corrode metal devices, and has a wide application range. The chelating agent chelates and disperses urine and soap scum, while the solvent dissolves urine and soap scum. Surfactants can play a wetting and penetrating role, making urine and soap scum easier to disintegrate, helping to improve the decontamination effect.

(2) The present invention can also increase flavoring components to remove peculiar smell.

(3) The present invention does not cause acid-base reaction during use, and does not produce unpleasant smell during use like existing toilet cleaners.

Detailed ways

The preparation method of following embodiment neutral toilet cleaning liquid:

1. Add demineralized water, start stirring, add chelating agent, raise the temperature to 50 ℃ ~ 80 ℃, and add thickener, stir for half an hour until the thickener is completely dispersed and dissolved.

2. Cool down to below 45°C, add solvent and surfactant in sequence, and stir until completely dissolved.

3. Add flavors, preservatives, and pigments.

4. Use an appropriate amount of citric acid or sodium hydroxide to adjust the pH value to 4~9 to obtain a neutral toilet cleaner.
