Problems solved by technology

However, the addition of these high-nutrient ingredients to the product not only protects the skin, but also creates more convenient conditions for the reproduction of microorganisms. If the preservatives in the product are not properly selected, it is easy to cause the product to change color, taste, mildew and smell, etc., making the product Lose due commercial value
In addition, if consumers use cosmetics with microorganisms exceeding the standard, it may cause adverse reactions such as skin redness and allergies. What's more, if they are contaminated by pathogenic bacteria, human health will be threatened. Pathogens and disease-causing bacteria that cause infection
Due to the commonly used cosmetic preservatives, such as formaldehyde and formaldehyde releasers, Bropol, organic halogens and paraben esters, these preservatives may form carcinogens or sensitizers, and have potential risks to the skin; Some cosmetic preservatives, such as Cathone, have chronic toxicity to the skin; there are also some preservatives, such as anisic acid, sodium benzoate, potassium sorbate, etc., which have relatively high acidity and alkalinity requirements for cosmetic systems. In order to play a role in anti-corrosion

preparation example Construction

[0034] In the present invention, the preparation method of Pulsatilla pulsatillae extract comprises the following steps:

[0035] (1) After taking 10g of Pulsatilla pulsatillae and pulverizing it, add 150ml of 65wt% ethanol aqueous solution, heat and reflux for 3 hours, filter, and recover the filter residue for subsequent use;

[0036] (2) After the filtrate obtained in step (1) is concentrated, it is diluted with distilled water, after being adsorbed by AB-8 resin, it is eluted with 60wt% ethanol for 45 minutes, and the eluent is concentrated and dried to obtain A powder;

[0037] (3) Take the filter residue in step (1), dry it, add 90wt% ethanol and 0.8 to 2 times the volume of the powder material after drying, extract with microwave for 1 hour, centrifuge and precipitate, and filter out the supernatant. Concentrate and dry to obtain B powder, and blend the A powder and B powder obtained in the step (2) in a weight ratio of (3-5): 1 to obtain the Pulsatilla pulsatillae extr...

Abstract

The invention relates to the field of daily chemical products, in particular to a plant source antibacterial agent and a preparation method thereof. The plant source antibacterial agent comprises thefollowing components in parts by weight: 20-33 parts of a pulsatilla cernua extract, 14-36 parts of a Chinese prickly ash extract and 20-38 parts of a tillandsia usneoides extract. The plant source antibacterial agent provided by the invention has a very high property of inhibiting growth of bacillus subtilis, escherichia coli, staphylococcus aureus, candida albicans, pseudomonas aeruginosa, aspergillus niger and the like, and a preservative property as well, besides, the stability of the agent can be also very well improved at a high temperature. In addition, cosmetics can be kept gentle whenantibacterial effects and high-temperature stability are maintained, and the agent has the characteristics of being non-toxic and non-irritant to human bodies.

Description

technical field [0001] The invention relates to the field of daily chemical products, in particular to a botanical antibacterial agent and a preparation method thereof. technical background [0002] With the improvement of people's living standards, the deepening of consumers' awareness and requirements for cosmetics, the safety of cosmetics is getting more and more attention. In recent years, relevant departments around the world have successively formulated regulations to strengthen the restrictions and supervision on the use of cosmetic preservatives. According to the official news released by the European Union, the European Commission has passed two directives restricting cosmetic preservatives, prohibiting the use of methylisothiazolinone and methylchloroisothiazolinone in leave-on skin care products such as skin creams. Mixed use in products; the other is to limit the maximum concentration of the two preservatives propylparaben and butylparaben from the current 0.8% ...
