Embodiment 1

[0060] Example 1: The preparation method of the ion-pair compound synthesized by lauroyl arginine ethyl ester hydrochloride and nicotinic acid

[0061] Dissolve 2.0 g of sodium nicotinate (purchased from TCI (Shanghai) Chemical Industry Development Co., Ltd.) in 50 mL of water to prepare sodium nicotinic acid salt solution (A); dilute 6.8 g of ethyl lauroyl arginate hydrochloride Dissolve in 40mL of water and heat to 90°C until ethyl lauroyl arginine hydrochloride is completely dissolved to make ethyl lauroyl arginine hydrochloride aqueous solution (B); Slowly add the saline solution (A) into the aqueous solution of lauroyl arginine ethyl ester hydrochloride (B), stir continuously, react for 2 hours, cool to room temperature, filter, wash the precipitate fully with pure water, and dry the precipitate under vacuum at 60°C. That is, 7.6 g of the nicotinic acid ion pair compound was obtained.

Embodiment 2

[0062] Embodiment two lauroyl arginine ethyl ester nicotinic acid ion pair compound molecular formula, the analysis of molecular weight

[0063] by mass spectrometry, 1 H-NMR, 13 The molecular formula of the compound obtained by C-NMR spectral analysis is:

[0064] 1. Mass spectrometry (ESI) analysis

[0065] Cation B + Molecular ion peak at m / z=385.3, see figure 1 ;

[0066] Anion A - Molecular ion peak at m / z = 122.1, see figure 2 .

[0067] The theoretically calculated value of the cation in the nicotinic acid ion-pair compound is 507.4, and the measured value is consistent with the theoretical value.

[0068] 2. NMR analysis

[0069] Ethyl lauroyl arginate hydrochloride (see image 3 ), niacin 1 H-NMR (see Figure 4 ) and LAE nicotinic acid ion pair compound 1 H-NMR (see Figure 5 )Compared. Due to the LAE ion-pair compound in the salt-forming process, the peak shape and chemical shift of lauroyl arginine ethyl ester in the ion-pair compound have little cha...

Embodiment 3

[0070] Example 3: Preparation method of ethyl lauroyl arginine hydrochloride and tartaric acid synthetic ion pair compound

[0071] Dissolve 2.0 g of tartaric acid (purchased from TCI (Shanghai) Chemical Industry Development Co., Ltd.) in 50 mL of methanol, add an equivalent amount of NaOH, stir at room temperature until a white solid precipitates, filter with suction and wash three times with 30 mL of methanol to obtain sodium tartrate . Sodium tartrate salt was dissolved in 50mL of water to make sodium tartrate aqueous solution (A); Dissolve 5.6g of ethyl lauroyl arginine hydrochloride in 40mL of water and heat to 90°C until ethyl lauroyl arginine salt The acid salt was completely dissolved to make ethyl lauroyl arginine hydrochloride aqueous solution (B); at 90°C, sodium tartrate aqueous solution (A) was slowly added to ethyl lauroyl arginine hydrochloride aqueous solution ( In B), stir continuously, react for 2 hours, cool to room temperature, filter, wash the precipitate...

Abstract

The invention provides an anticorrosion agent or anti-mildew agent for wipes, which comprises LAE (N(alpha)-lauroyl arginine ethyl ester) and its ion pair derivative. The invention also provides a method for preparing an anticorrosion agent or anti-mildew agent for wipes and an anticorrosion agent or anti-mildew agent for wipes, prepared via the method. The anticorrosion agent or anti-mildew agentfor wipes has the advantages of good naturalness and zero toxicity, high antibacterial performance, good degradability, and good environmental friendliness.

Description

technical field [0001] The present invention relates to an antiseptic and antiseptic wet tissue, in particular to an antiseptic and antiseptic wet tissue containing ethyl lauroyl arginate and its derivatives (ion pair compound), the ethyl lauroyl arginate and its ion pair derivatives It has antibacterial effect, which can help wet wipes to exert antibacterial and antiseptic effects while exerting moisturizing function. Background technique [0002] With the continuous improvement of people's living standards, people's consumption of wet wipes is also constantly increasing, and there are more and more varieties of wet wipes. From hotel wet towels, car wipes, makeup remover wipes, mask wipes to children's hygiene wipes, etc., the production scale of wet wipes has also expanded from manual workshops to automatic production lines. As far as the many occasions and functions of wet wipes are concerned, wet wipe manufacturers are all required to strictly disinfect wet wipes during...
