Description
Technical Field
The invention belongs to the technical field of daily chemicals, and relates to a weakly acidic body wash and a preparation method thereof.
Background
Currently, the bath lotions on the market are divided into surfactant type and soap-based type. Soap-based shower gel and alkaline surfactant shower gel have strong cleaning ability but large irritation to skin, while acidic surfactant shower gel has mild property and good skin moistening and nourishing effects, but has poor washability and unsatisfactory cleaning ability.
Meanwhile, the existing acidic bath lotion is usually adjusted in pH by a pH regulator (such as citric acid) in the final preparation step, so that the pH of the bath lotion is acidic, but the cleaning capability of the bath lotion after the pH adjustment is weakened, the cleaning capability does not achieve the ideal effect, and the bath lotion is not suitable for people with large skin oil output and is narrow in applicable people. And because the pH needs to be adjusted to be weakly acidic at last, namely, the steps of preparing the pH regulator, adding the pH regulator and uniformly stirring, detecting the pH and the like are added, and the time occupied by the pH adjusting step in the common bath cream production process accounts for 15-25% of the whole bath cream production time, the production efficiency is low, the equipment cost is increased, and the production cost is increased.
The surfactants which can be used as active components in the shower cream in the prior art are various, and by combining the surfactants or the combination of the surfactants with other components, the weakly acidic shower cream with strong cleaning capability can be directly prepared without a pH adjusting step to adjust the pH value of a final system to be weakly acidic, which is difficult to predict. Therefore, it is very important to develop a novel body wash capable of solving the above problems.

Table 2 cleaning power test results of the shower milks of examples 1 to 6
Table 3 cleaning power test results of 7 kinds of shower milks in comparative examples 1 to 6
As can be seen from the data in tables 2 and 3, the above-mentioned shower creams are, in order of the oil stain cleaning time H per unit weight, shower cream A < shower cream E < shower cream C < shower cream F < shower cream B < shower cream D < shower cream H (basic shower cream) < shower cream J < shower cream M < shower cream K < shower cream I < shower cream G (weakly acidic shower cream) < shower cream L.
The cleansing time h is ranked as described above, and the cleansing milk a of the present invention has the best cleansing ability. The cleaning time of the shower creams A-F of the invention is 24.22%, 94.91%, 55.24%, 99.55%, 40.32% and 74.67% of that of the alkaline shower cream H, respectively, which shows that the cleaning ability of the shower creams A-F is equivalent to or obviously better than that of the commercial alkaline shower cream H. The cleaning time of the shower creams A-F of the invention is respectively 19.28%, 75.56%, 43.98%, 79.27%, 32.11% and 59.45% of the weak acid shower cream G sold on the market, which shows that the cleaning ability of the shower creams A-F is obviously better than that of the weak acid shower cream G sold on the market.
After one surfactant is replaced by the bath cream I-K, the pH of the obtained bath cream is adjusted to be within the range of 5.5-7 by a pH regulator. Meanwhile, as can be seen from the data in tables 2 and 3, none of the baths I to K had a cleaning power much inferior to that of the baths A to F obtained under the conditions of the specific formulations of the present invention, and was far inferior to that of the baths A, C, E and F of the present invention.
Meanwhile, as can be seen from the data in tables 2 and 3, the formula component content of the body wash L is not within the protection range of the present invention, the cleaning time is 2.7 to 11.2 times of that of the body wash of the present invention, and the cleaning time is much longer than that of the present invention, i.e., the cleaning power is far inferior to that of the body wash of the present invention, the formula component content of the body wash M is not within the protection range of the present invention, the cleaning time is 1.04 to 4.3 times of that of the body wash of the present invention, and the cleaning time is also longer than that of the body wash obtained under the specific formula conditions of the present invention, i.e., the cleaning power is inferior to that of the present invention.
Example 8 clinical test of cleaning ability
40 test subjects (20 men and women, age group 15 to 55 years, 50% of those with high skin oil content) were randomly selected, and comparative tests were performed on the body lotions A to F prepared in examples 1 to 6, the body lotions G to H of comparative example 1, and the body lotions I to M of comparative examples 2 to 6, respectively. Each example and comparative example were measured in parallel 3 times. The testers scored according to their own feelings after using the shower cream.
Evaluation items: cleanliness and skin feel after washing (tightness, mildness, no stimulation, moistening and the like).
Grading standard: score 1 indicates worst and score 5 indicates best. The average score of all tester scores was then used as the evaluation result.
The test method comprises the following steps: the tester tries to keep the state consistent before each bath. Each time, the tester took an equal amount of bath cream (2.0ml) on the wet ball, rubbed the ball 10 with both hands, then gently rubbed the ball throughout the body for 2 times, and finally washed clean with clear water. The evaluation results are shown in tables 4 and 5.
TABLE 4 evaluation results of volunteers using the shower milks of examples 1 to 6
TABLE 5 volunteers evaluation results of feeling of bathing milk using comparative examples 1 to 6
As is apparent from the data in tables 4 and 5, the body lotions A to F prepared in examples 1 to 6 of the present invention had very excellent cleansing ability, and the skin feel after cleansing was good, no tightness, mildness of body lotions, and skin moistening and elasticity. The cleaning degree of the shower creams A-F according to the invention is comparable to or even significantly better than that of the commercially available alkaline shower creams H. The cleaning degree of the body lotions A to F of the present invention is significantly better than that of the commercially available weakly acidic body lotion G. The cleaning degree of the body lotions I to M of the comparative examples was significantly poorer than that of the body lotions A to F of the present invention. Meanwhile, although the cleanliness of the body wash M is good, the skin-feel effect of the body wash M is deteriorated due to the low water content in the body wash M formulation.
As can be seen from the comparison of the data in tables 4 and 5, the effect of the body lotion of the present invention could not be achieved when different conventional anionic surfactants, zwitterionic surfactants and amino acid surfactants were selected, indicating that the body lotion prepared by selecting the above specific components of the present invention could achieve excellent cleansing and post-wash skin feel. The shower cream with the pH value of 5.5-7 can be directly prepared according to the formula, the subsequent pH adjusting step is not needed, the production process is obviously simplified, the production efficiency is improved, and the production cost is reduced. According to the experience in the field, the production efficiency can be improved by about 15-25% due to the omission of the pH adjusting step. The yield per unit time can be increased by 15-25%, and the economic benefit brought by the method is very obvious.
The embodiments of the present invention have been described in detail, but the embodiments are merely examples, and the present invention is not limited to the embodiments described above. Any equivalent modifications or alterations to this practice will occur to those skilled in the art and are intended to be within the scope of this invention.
