Problems solved by technology

However, the foaming ability and foam stabilizing ability of the extract of Sapindus chinensis are not ideal, especially at low temperature, and there is also the shortcoming that the decontamination is not strong with the extract of Sapindus chinensis alone as the surfactant. Detergents with substances as the main surfactants all have the disadvantages of unsatisfactory low-temperature foaming power, insufficient rich and lasting foam, and weak detergency

Embodiment 1

[0029] Embodiment 1, the preparation of acidic oxidized tea polyphenols

[0030] Weigh tea polyphenols and dissolve them in deionized water to form a tea polyphenols aqueous solution, keep warm with circulating water at 20°C, stir, add 0.01mol / L acetic acid solution to make the pH of the reaction solution 2.9, and oxidize for 30 minutes. After the end, add ethyl acetate twice the amount of the reaction solution, centrifuge and separate layers, take the supernatant, concentrate under reduced pressure to form an extract, and spray dry to obtain acidic oxidized tea polyphenols.

[0031] Wherein, in the above preparation process, the concentration of tea polyphenols in the tea polyphenols aqueous solution is 5 g / L; the ventilation rate is 0.5 L / min.

Embodiment 2

[0032] Embodiment 2, preparation of enzymatically oxidized tea polyphenols

[0033] Weigh tea polyphenols and dissolve them in deionized water to form an aqueous solution of tea polyphenols (use a pH regulator to adjust the pH to 5.5), keep warm with circulating water at 37°C, add polyphenol oxidase while stirring, and feed air during the reaction process to enzymatically Oxidation reaction was carried out for 50 minutes. After the reaction was completed, the enzyme was inactivated, ethyl acetate was added to the reaction solution twice as much, centrifuged and separated, the supernatant was taken, concentrated under reduced pressure to form an extract, and spray-dried to obtain enzymatically oxidized tea polyphenols.

[0034] Wherein, the concentration of tea polyphenols in the aqueous solution of tea polyphenols may be 3 g / L; the concentration of the polyphenol oxidase in the reaction solution is 1.5 g / L; the ventilation rate is 0.6 L / min.

Embodiment 3～5

Abstract

The invention belongs to the technical field of washing products, and particularly relates to a bacteriostatic detergent containing a plant surfactant and a preparation method of the bacteriostatic detergent. The bacteriostatic detergent containing the plant surfactant comprises the following components in percentage by mass: 10-25% of Chinese soapberry seed extract, 1-8% of compound oxidized teapolyphenol, 1-3% of antibacterial agent, 0.5-1.5% of emollient, 0.1-1% of aromatic, 0.1-4% of thickener, 0.01-0.1% of chelating agent, 0.1-0.3% of preservative and the balance of water. According to the detergent, the Chinese soapberry seed extract is compounded with two types of oxidized tea polyphenol to serve as a surfactant system, so that the prepared detergent has excellent high-temperatureand low-temperature foaming capacity and foam stabilizing capacity, the detergency is obviously improved, the overall washing performance is good, and the performance is excellent.

Description

technical field [0001] The invention belongs to the technical field of washing products. More specifically, it relates to a plant-surfactant-containing antibacterial detergent and a preparation method thereof. Background technique [0002] At present, most detergents use petroleum-derived products such as sodium alkylbenzene sulfonate (LAS) and fatty alcohol polyoxyethylene sodium sulfate (AES) as the main foaming and decontamination components. These two surfactants are easily soluble in water. Moreover, it is cheap and has good washing performance and is widely used. However, LAS and AES are prone to residues, which pose a potential threat to human health. [0003] Based on this, some products that use natural surfactants to replace petroleum surfactants have appeared in the market. Commonly used natural surfactants mainly include saponins, such as Sapindus chinensis extract, etc., which are rich in saponins and have Antibacterial and cleaning effects, therefore, the di...
