Description

Natural mild shower gel and preparation method thereof

Technical Field

The invention relates to the field of daily chemicals, and particularly relates to natural mild shower gel and a preparation method thereof.

Background

Along with the improvement of living standard of people, the requirements on the shower gel are increased, for example, the shower gel which is milder, safer and does not stimulate the skin is needed, and meanwhile, the antibacterial effect of the shower gel is also emphasized, and the micro-ecological balance of the skin is maintained.

The shower gel on the market is of a common type: one is a bath lotion mainly based on a soap base type, and the other is a bath lotion mainly based on a synthetic surfactant, and the bath lotion which can be natural, mild and bacteriostatic is less. The soap-based shower gel is strong in degreasing capability, can bring refreshing feeling, clean feeling and abundant foam experience to human bodies, and can cause discomfort of dry and tight skin of partial people. Although synthetic surfactant-based body washes do not dry the skin relatively, the residual feeling of incomplete washing causes skin itching, skin sensitization, and the like in some consumers.

Along with the change of the living environment of people, consumers have higher requirements on the shower gel, can be more natural and milder to clean the skin, and hopefully can also play a role in protecting the skin, particularly for people with low immunity such as old people and children, and need to protect the body of the people through an external intervention mode. If the bacteriostatic effect is not enough, unnecessary cross infection can be caused. Therefore, the market needs a more natural and mild antibacterial shower gel to meet the daily requirements of consumers, which becomes a technical problem to be solved urgently.

The shower gel disclosed by the embodiments 1-16 of the invention is safe and non-irritant, and the natural mild shower gel can be safe and mild to the skin.

Experiment of corrosion prevention challenge

Corrosion challenge experiments were conducted according to the method of European pharmacopoeia (EP7.0) with reference to comparative example 6, and the test results are shown in Table 7 below

Table 7 corrosion protection challenge experimental results

As can be seen from table 7, the present invention can effectively reduce the risk of contamination of the product with microorganisms by adding the natural preservative, while comparative example 6, in which no natural preservative is added, is higher at 7 days, 14 days, 21 days and 28 days, with the risk of contamination with microorganisms.

Human sensory evaluation

300 volunteers were recruited and grouped randomly after grouping, 20 volunteers per group were continuously used for 8 weeks with each group of body wash, and the testers scored according to the use feeling. The scoring criteria used a 7 point scale, with 1 point being the worst, 7 points being the best, with higher points being better. The final results are shown in Table 8 below.

TABLE 8 human sensory evaluation

As can be seen from table 8, the bath lotion composition of the present invention has greater advantages in terms of easy rinsing after use, bacteriostasis, itching relieving, moisture retention after use, etc., compared with the commercially available bath lotion S. Is popular with testers.

The soap tree saponin is not contained in comparative example 1, the tea saponin is not contained in comparative example 2, the foaming speed and the foam richness of the shower gel composition are poor, the scores in two aspects of the soft foam of the shower gel and whether the shower gel is easy to wash out after use are poor, and the surface activity is poor.

The rush iris extract is not contained in comparative example 3, the honeysuckle extract is not contained in comparative example 4, and the pinus densiflora extract is not contained in comparative example 5, so that the itching relieving effect of the shower gel composition after use is poor, and the shower gel composition cannot effectively inhibit bacteria.

Comparative example 6 has no preservative, the abundance of foam of the body wash composition and the antipruritic effect of the body wash after use are poor, and the risk of microbial contamination exists in the experiment of antiseptic challenge.

In comparative example 7, the moisturizing agent is not present, the moisturizing effect of the shower gel composition is poor, the antibacterial effect is not good, and the shower gel composition is not favored by testers in appearance preference.

In comparative example 8, no thickener was present, the appearance and foaming properties of the body wash composition were poor, and both the moisturizing performance and the bacteriostatic effect of the body wash were reduced.

The fragrance-free shower gel composition of comparative example 9 had poor overall satisfaction and overall preference.

In comparative example 10, the excessive amount of quillaja saponin was added, and in comparative example 11, the excessive amount of tea saponin was added, so that although the bath composition had satisfactory foam density, the moisture retention and itching after use were increased, and the bath composition was not easily rinsed out, and the satisfaction of the testers was reduced.

The results show that the shower gel disclosed by the invention is good in use feeling, has the effects of mildness, bacteriostasis and the like, has a synergistic effect among the components, and is good in overall use effect.

The above detailed description of the preferred embodiment of the present invention is the result of many tests which the inventor has spent on a lot of manpower, money and time.
