Embodiment 1

[0044] (1) Preparation of sucrose fatty acid ester mixture: heat 40g of palm oil, 0.50g of sodium hydroxide, and 35mL of methanol in a reactor to about 70°C, stir, and reflux for 4 hours; then stop the reaction, cool down, and transfer to In the separatory funnel, let the layers stand to remove the lower layer of glycerol; take the upper layer, and recycle the excess methanol by rotary evaporation; then wash with brine to remove residual soap and catalyst to obtain fatty acid esters,

[0045] Take 5g of the fatty acid ester obtained above, 5.0g of sucrose, 3.0g of sodium carbonate, and 20mL of propylene glycol in a reactor, heat to 85°C, stir, and react for 7h; then stop the reaction, and the resulting product is a mixture of sucrose esters ;

[0046] (2) Take 10% of sucrose ester mixture according to the formula, 5% of propylene glycol, 10% of ethanol, 1.0% of pectin, 0.1% of sodium carbonate, and the rest is distilled water;

[0047] (3) Dissolving the thickener and sodium ...

Embodiment 2

[0050] (1) Preparation of sucrose fatty acid ester mixture: heat 45g soybean oil, 0.45g potassium hydroxide, and 25mL ethanol in a reactor to about 75°C, stir, and reflux for 3.5h; then stop the reaction, cool down, and transfer to In a separatory funnel, let stand to separate the layers, remove the lower layer of glycerin; take the upper layer, and rotary evaporate to recover excess ethanol; then wash with brine to remove residual soap and catalyst to obtain fatty acid ester.

[0051] Take 4g of the fatty acid ester obtained above, 4.5g of sucrose, 1.5g of potassium carbonate, and 15mL of propylene glycol in a reactor, heat to 95°C, stir, and react for 5h; then stop the reaction, and the obtained product is a mixture of sucrose esters;

[0052] (2) Take 15% of sucrose ester mixture according to the raw material formula, 10% of propylene glycol, 10% of ethanol, 1% of sodium carboxymethyl cellulose, 0.15% of sodium carbonate, and the rest is distilled water;

[0053] (3) Dissol...

Embodiment 3

[0056] (1) Preparation of sucrose fatty acid ester mixture: heat 30g of palm oil, 0.5g of potassium hydroxide, and 30mL of methanol in a reactor to 80°C, stir, and reflux for 3h; In a liquid funnel, let stand to separate the layers, remove the lower layer of glycerin; take the upper layer, rotary evaporation to recover excess methanol, and then wash with brine to remove residual soap and catalyst to obtain palm oil methyl ester.

[0057] Take 4g of palm oil methyl ester obtained above, 6g of sucrose, 2.5g of potassium bicarbonate, and 25mL of propylene glycol in a reactor, heat to 90°C, stir, and react for 6h; then stop the reaction, and the obtained product is a mixture of sucrose esters ;

Abstract

The invention provides a safe environment-friendly tableware detergent and a simple preparation method thereof. The safe environment-friendly tableware detergent comprises the following components in percentage by mass: 5-25% of sucrose ester mixture, 1-15% of emulsifier, 5-25% of ethanol, 0.1-2% of thickener, 0.05%-0.2% of sodium carbonate and the balance of water, wherein the preparation process of the sucrose ester mixture comprises performing an alkali salt catalyzed reaction on aliphatic ester and cane sugar in an alcohol solvent system at 70-95 DEG C for 4-8 hours, and the reaction product is directly applied to the safe environment-friendly tableware detergent without separation. The preparation method of the safe environment-friendly tableware detergent is simple and easy to operate; the tableware detergent is safe and easily degradable, pollution-free, easy to remove and low in cost; the tableware detergent is suitable for washing tableware with hands due to the capability of moistening skin and strong bacteriostatic action, and has a great popularization value.

Description

technical field [0001] The invention relates to the field of daily chemical industry, in particular to a safe and environment-friendly dish detergent. Background technique [0002] Dishwashing detergent is indispensable in kitchen supplies. At present, most of the dishwashing detergents contain irritating surfactants such as linear alkylbenzene sulfonate and fatty alcohol polyoxyethylene ether sulfate. Long-term use will damage the It causes damage to the skin and causes rough skin; it is not easy to rinse, which not only wastes water resources, but also chronically endangers human health due to unclean rinse; in addition, it is not easy to be degraded after use, and it is easy to pollute the environment. [0003] With the gradual improvement of people's living standards, people pay more and more attention to the safety of food, not only the food itself, but also the utensils used to hold food. The general tableware detergent is irritating and easy to remain on the tableware...
