Description

Surfactant composition, female fragrance shower gel containing surfactant composition and preparation method of shower gel

Technical Field

The invention belongs to the technical field of washing and caring articles, and particularly relates to a surfactant composition, a female fragrance shower gel containing the surfactant composition and a preparation method of the shower gel.

Background

Human skin secretes sweat and oil, and also adheres to skin flakes removed from the skin, and dust and bacteria in the living environment cover the skin, causing skin itch if not cleaned in time, and causing various skin problems in severe cases. In order to remove various stains on the skin surface more effectively, people can use a bathing article such as soap for decontamination during bathing, and although the soap has good decontamination capability, the soap can cause excessive dehydration of the skin after cleaning, so that the skin is dry.

The bath lotion is a common liquid body cleaning product, is mainly prepared from a surfactant and a skin care component, and has the capability of cleaning and decontaminating the skin. Compared with the traditional perfumed soap, the shower gel has the characteristics of convenient use, easy cleaning, hard water resistance, rich foam and the like. Therefore, in recent years, the yield and sales of the bath cream are continuously increased, and the bath cream becomes a mainstream product of bath cleaning and conditioning products and gradually replaces the position of the soap.

CN107802526A discloses a super-strong decontamination transparent shower gel, which comprises, by weight, 22-25 parts of lauryl alcohol polyoxyethylene ether ammonium sulfate, 8-12 parts of a seaweed extract, 5-10 parts of boric acid, 13-18 parts of lauric acid, 16-22 parts of Ethylene Diamine Tetraacetic Acid (EDTA), 25-30 parts of hydroxyethyl cellulose, 20-25 parts of triethanolamine, 12-15 parts of glycerol cocoamide betaine and 60-70 parts of deionized water. The shower gel disclosed by the invention can strongly remove skin dirt, increase foam and reduce soap dirt, the formula is a mild raw material, and meanwhile, EDTA can prevent the product from being turbid when meeting hard water, so that the transparency of the product is ensured.

CN109223686A discloses a formula of refreshing shower gel with skin moistening and caring functions, which comprises, by weight, 10-14 parts of green tea powder, 10-14 parts of aloe extract, 10-14 parts of mint leaf, 6-10 parts of grape seed, 10-14 parts of sweet orange extract, 2-6 parts of milk, 3-7 parts of pearl powder, 3-7 parts of bamboo charcoal powder, 8-12 parts of glycerol, 8-12 parts of natural beewax, 1-5 parts of vitamin E, 3-9 parts of emulsifier, 3-7 parts of humectant, 3-7 parts of diatomite, 1-5 parts of essence and 2-10 parts of deionized water. The shower gel disclosed by the invention can effectively nourish the skin and improve the use experience of a user.

However, the current common body wash still has the following disadvantages: 1. by adopting the traditional surfactant, the shower gel has the advantages of low foaming speed, less and rough foaming and weak shower experience; 2. the foam is not melted when meeting water, is difficult to wash, often needs to be repeatedly kneaded, and still has sticky residual feeling after cleaning; 3. the bath lotion has too strong cleaning power, and the skin is dry and tight after cleaning.

Therefore, a shower gel product which has the advantages of quick foaming, easy rinsing and good moisturizing effect is to be developed to meet the market demand.

Test areas of 3cm × 3cm are drawn on the left and right sides of the neck of the subject, and 0.5mL of the body wash provided in application examples 1 to 8 and application comparative examples 1 to 6 and 0.5mL of distilled water are mixed and applied to the left test area of the neck of the subject, and the right test area is applied with the same amount of distilled water. The subject gently rubbed the left neck with the left hand and the right neck with the right hand, and the time to onset of blistering was recorded, with the results shown in table 4 below:

TABLE 4

As can be seen from Table 4, the fragrance shower gel for women provided by the invention has the advantages of high foaming speed on skin, and foaming time of about 4-5s, which is obviously shortened compared with that of a comparative example.

Test example 4

Skin moisturizing effect test

140 female volunteers between the ages of 30-40 were selected as subjects, randomized into 14 groups of 10 persons each. Respectively drawing test areas with the size of 3cm multiplied by 3cm on the inner sides of the left forearm and the right forearm of a subject, and testing the moisture content of the skin of the test areas of the subject by using a skin moisture tester; then 0.5mL of the body wash provided in application examples 1 to 8 and application comparative examples 1 to 6 was uniformly applied to the test area of the left arm of the subject, respectively, a placebo cream was applied to the test area of the right arm as a blank, the body wash in the test area of the left arm was wiped off after 5min, the skin moisture content in the test area was measured using a skin moisture tester, and the subject was tested in an environment of 27 ℃ and 50% humidity and kept without vigorous exercise. After 2h, the skin moisture content of the test area was again measured, and the variation value of the skin moisture content was calculated, and the evaluation criteria and the test results of the skin moisturizing effect were as shown in tables 5 and 6 below, respectively:

TABLE 5

Grade of moisturizing effect	Is on the low side	Medium and high grade	Good effect	Is excellent in
					2h water content change value	≤10％	10-20％	20-30％	≥30％

TABLE 6

As can be seen from the results of table 6, the body washes provided in application examples 1 to 8 and application comparative examples 1 to 4 each had a good moisturizing effect because they contained various moisturizers in their formulations to help keep the skin tender and smooth, and the application comparative example 5 contained no moisturizer and therefore had a poor moisturizing effect, whereas the application comparative example 6 contained only glycerin as a moisturizer and had a poor moisturizing effect compared to the moisturizer provided in the present invention.

Test example 5

Consumer sensory evaluation test

Evaluation was made by evaluating the easy-to-rinse feel and stain-removing effect of the body washes of application examples 1 to 8 and application comparative examples 1 to 6 using a scoring system. The subjects were 140 female volunteers between the ages of 30-40, randomized into 14 groups of 10 individuals each. The whole body of the trial part is independently selected from 8 experimental groups and 6 control groups, and the shower gel of application examples 1-8 and application comparative examples 1-6 is respectively adopted for bathing in the evening every day for 30 days. Subjects scored the rinse-off feel and stain removal effect separately.

The total score of the using effect of each item is 5 points, and 4.1-5 points show better and very satisfactory; 3.1-4 points are good; 2.1-3 are acceptable; 1.1-2 are unacceptable; a score of 0-1 is very poor and completely intolerable. The results are shown in Table 7:
