Problems solved by technology

Soap-based shower gels and alkaline surfactant-based shower gels have strong cleaning power but are highly irritating to the skin, while acidic surfactant-based shower gels are mild in nature and have a good moisturizing and skin-nourishing effect. The performance is not good, and the cleaning ability can not achieve the desired effect
[0003] At the same time, the body wash of the existing acidic system usually adjusts the pH by a pH regulator (such as citric acid) in the final step of preparation, so that the body wash The pH is acidic, but after adjusting the pH in this way, the cleaning ability of the shower gel is weakened, and the cleaning ability cannot achieve the desired effect. It is not suitable for people with a large amount of oily skin, and the applicable population is narrow
And because the pH needs to be adjusted to weak

Embodiment 1-6

[0088] Embodiment 1-6, the preparation of weakly acidic body wash

[0089] The formula of weakly acidic body wash of embodiment 1-6 is as shown in table 1.

[0090] The weakly acidic body wash formula of table 1 embodiment 1-6

[0091]

[0092] The preparation method of the body wash of embodiment 1-6 comprises the steps:

[0093] (1) Add the formulated amount of water into the container and heat it to 60±5°C, then add the formulated amount of anionic surfactant, zwitterionic surfactant, amino acid surfactant, preservative chlorphenesin, and Hydroxyacetophenone, stir evenly, continue heating to 72±3°C, and stir evenly;

[0094] (2), keep the temperature at 72±3°C, add the formula amount of methyl gluceth-20, propylene glycol stearate, PEG-120 methyl glucose dioleate, jojoba seed oil in sequence, and stir Uniform;

[0095] (3) Add PEG-7 glyceryl cocoate into the container, keep the temperature at 72±3°C, stir for 35±5 minutes until the raw materials are evenly mixed;

Embodiment 7

[0144] Embodiment 7, cleaning ability detection

[0145]Apply the standard oil stain on the weighed glass slide, use the shower gel solution of a certain concentration to perform ultrasonic cleaning, and record the time required for the oil stain on the slide to be washed off, so as to judge the cleaning ability of the shower gel. The experimental steps are as follows:

[0146] (1) Prepare artificial oil (200g butter, 200g vegetable oil, 20g glyceryl monostearate), heat the beaker equipped with artificial dirt to 180°C on a closed electric furnace, stir, maintain the temperature for 10min, spontaneously ignite, cool and stir to 50°C for later use.

[0147] (2), prepare hard water: take by weighing 3.7g anhydrous magnesium sulfate and 5.0g anhydrous calcium chloride, fully dissolve in 5000ml distilled water.

[0148] (3), preparation of shower gel solution: take 2g of shower gel, dilute to 200ml with hard water and set aside.

[0149] (4), the glass slide is cleaned with dei...

Embodiment 8

[0159] Embodiment 8, cleaning ability clinical test

[0160] Randomly select 40 testers (20 men and women, age group 15 to 55 years old, wherein people with a large amount of oily skin account for 50%), respectively test the body washes A-F prepared in Examples 1-6 and Comparative Example 1 Shower milks G-H and shower milks I-M of Comparative Examples 2-6 were subjected to a comparative test. Each example and comparative example were measured in parallel 3 times. Testers rated the products based on how they felt after using the body wash.

[0161] Evaluation items: cleanliness, skin feeling after washing (tightness, mild and non-irritating, moisturizing, etc.).

[0162] Scoring criteria: 1 point is the worst, 5 points is the best. Then the average score of all testers is used as the evaluation result.

[0163] Test method: Testers try to keep the same state before each bath. The tester took an equal amount of body wash (2.0ml) on the wet bath ball each time, rubbed the ba...

Abstract

The invention discloses weak acid body wash. The weak acid body wash is prepared from the following active components in percentage by weight: 2-20% of an anionic surfactant, 1-10% of a zwitterionic surfactant, 0.5-10% of an amino acid surfactant, 1-15% of PEG-7 glyceryl cocoate, 0.5-10% of an acrylate copolymer, 0.5-10% of methyl gluceth-20, 0.1-1% of PEG-120 methyl glucose dioleate, 0.1-5% of propylene glycol stearate, 0-1% of simmondsia chinensis seed oil, 0-2% of p-hydroxyacetophenone and the balance of water. A proper amount of a preservative is added. The pH is 5.5-7.0. The anionic surfactant is selected from one or two of ammonium laureth sulfate and disodium laureth sulfosuccinate. The zwitterionic surfactant is selected from one or more of cocamidopropyl betaine, lauryl betaine and lauramidopropyl betaine. The body wash has a strong cleaning capability and is moderate. The pH does not need to be additionally adjusted, the production technology is simplified, and the productionefficiency is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of daily chemicals, and relates to a weakly acidic body wash and a preparation method thereof. Background technique [0002] Shower milks currently on the market are divided into surfactant-based and soap-based types. Soap-based shower gels and alkaline surfactant-based shower gels have strong cleaning power but are highly irritating to the skin, while acidic surfactant-based shower gels are mild in nature and have a good moisturizing and skin-nourishing effect. The performance is not good, and the cleaning ability can not achieve the desired effect. [0003] Simultaneously, the body wash of existing acidic system usually adjusts the pH by a pH regulator (such as citric acid) in the final step of preparation, so that the pH of the body wash is acidic, but the cleaning ability of the body wash after adjusting the pH like this Weakened, the cleaning ability can not achieve the ideal effect, it is not suitabl...
