Problems solved by technology

[0005] The reasons for the instability of sodium hydroxymethylglycinate solution are complicated, and no research on related problems has been found yet
Preliminary experiments have also verified that not only are there significant differences between different manufacturers, but also the differences between different batches of products from the same manufacturer are also very large. In addition, the same batch of products has also undergone different changes due to storage and other factors (these differences are mostly reflected in the product quality). color deepening and precipitation), which also greatly increases the difficulty of finding and solving related problems

Embodiment 1

[0030] Sample A from Manufacturer A 1 ,

[0031] List of compositions to be selected:

[0032]

[0033] Weigh 12 parts of 100g sample A respectively 1 , add 1g, 3g, 10g of each of the above 4 groups of compositions to be selected respectively, and weigh 1 part of 100g sample A 1 , as a blank sample, put the above 13 samples in a water bath at 60°C for 2 hours.

[0034] Observation of color change: Using platinum-cobalt colorimetry, the blank sample has the darkest color, and the chroma is greater than 500 black increments. The addition of 1# composition is the best effect, and the color is the lightest, and the chroma is less than 20 black increments, followed by The addition amount of 4# composition is 10%, the color is slightly yellow, and the chromaticity is between 30-40 black increase.

Embodiment 2

[0036] Manufacturer A, Sample A 2 、A 3 The production raw materials, feeding amount and production process are the same as sample A 1 , the difference between sample A 2 Additional 1% of 1# composition is added during the production process; A 3 After the original production process is finished, 1% of the 1# composition is added and stirred for 20 minutes.

[0037] A 1 、A 2 、A 3 Under the same storage conditions, observe it, and the chromaticity changes over time are as follows:

[0038]

[0039] At the same time, observe the precipitation situation:

[0040]

[0041] The product obtained according to the above scheme of adding the composition, such as A 2 、A 3 , which can extend the shelf life of the product to 24 months or longer.

Embodiment 3

[0043] Sample B from manufacturer B 1 , B 2 , B 3

[0044] List of compositions to be selected:

[0045]

[0046] Weigh 6 parts of 10g sample B1, add 0.05g of each of the above 4 groups of compositions to be selected, and weigh 1 part of 100g sample B1 as a blank sample, put the above 7 samples in a boiling water bath for 2 minutes.

[0047] Comparing the color difference, the lightest one is the best, and it is determined that the addition of 6# composition is 0.5% and the effect is the best.

[0048] Weigh 3 parts of 100g sample B respectively 1 , B 2 , B 3 , add 0.1g, 1g, 10g of the above 6# composition respectively, and weigh 3 parts of 100g sample B respectively 1 , B 2 , B 3 , as a blank sample, put the above 12 samples in an oven at 50°C for 48 hours.

[0049] Comparing the color difference, the lightest one is better, and it is determined that for B 1 , B 2 The addition of sample 6# composition is 1% and the effect is the best; for B 3 Sample 6# composi...

Abstract

The invention relates to a composition capable of enhancing stability of a sodium hydroxymethyl glycinate solution and a screening method for selecting specific components, contents and addition amounts of the specific composition for a certain sodium hydroxymethyl glycinate solution sample. The invention solves the common problems of low stability, high discoloration tendency, high storage requirement, short shelf life and the like in the sodium hydroxymethyl glycinate solution. The screening method overcomes the uncertain factors for causing the product instability, such as discoloration / precipitation and the like, is free from the influence of the product raw materials, technique and the like, and has the advantages of high application flexibility and wide range.

Description

technical field [0001] The invention relates to a composition for improving the stability of different sodium hydroxymethylglycinate solutions, and a screening method for how to select a specific composition for different sodium hydroxymethylglycinate solutions. Background technique [0002] Sodium hydroxymethylglycinate is the most widely used new preservative in the world in the 1990s. It has high-efficiency broad-spectrum antibacterial activity and has inhibitory effects on bacteria, molds and fungi. It is one of the very few that can still maintain activity at high pH values. One of the preservatives widely used in cosmetics industry, food industry, paint industry, paper industry and pharmaceutical industry and other fields. [0003] The 50% aqueous solution containing sodium hydroxymethylglycinate is mostly used in the market, which is slightly alkaline. When compounded with other preservatives, it can effectively prevent and control complex microorganisms and molds in ...
