Refreshing, moisturizing, whitening and repairing sun block and preparation method thereof

Technical Field

The invention relates to the field of skin care products, and particularly relates to a sunscreen lotion for refreshing, moisturizing, whitening and repairing and a preparation method thereof.

Background

Sunlight is one of the essential elements for human survival and health, but it also causes many acute and chronic damages to the skin. With the improvement of the life quality of people, the skin care concept is gradually popularized from facial care to the whole body. Under the strong ultraviolet irradiation in summer, the skin barrier is easily damaged, skin collagen and elastic fiber tissues are also damaged, the ductility of the skin is weakened, and the symptoms of skin suntan, sunburn, erythema, pruritus, pain, even ulcer and the like can be caused. The long-term ultraviolet irradiation causes allergic reactions such as skin allergy, swelling, stabbing pain, etc. Ultraviolet rays can cause skin elasticity loss, cause aging phenomena such as skin wrinkles, rough skin, skin looseness and the like, change nutrient structures in skin and even cause serious diseases such as skin cancer, melanoma, actinic keratosis and the like.

In response to this phenomenon, various sunscreen products such as sunscreen creams are available on the market. The sunscreen emulsion is a skin care product prepared by utilizing a sunscreen principle and used for protecting skin from being irradiated by ultraviolet rays so as to avoid the generation and accumulation of melanin, is applied to the skin to prevent sunlight from contacting the skin, and has the effects of whole-body sunscreen, refreshing and moisturizing and skin nourishing. In hot summer, ultraviolet rays seriously affect the skin state of people and cause damage to the skin of the human body to different degrees, but the existing products have the defects of greasiness, mud rubbing, low sun protection, false whitening, poor skin feel and the like. When the sun-screening products on the market cannot meet the requirements of people, the skin needs the sun-screening cream which is fine and uniform in texture, fresh, moisturized, non-sticky, rapid in absorption, good in skin feel, ultraviolet-proof, light-aging-proof, moisturizing, whitening and after-sun repairing to protect the skin.

Comparative example 1

The formulation and preparation method were the same as in example 3 except that no dimethylsilicone oil was added to the formulation and preparation method of comparative example 1.

Example 4

The physical and chemical indexes of the examples 1,2 and 3 and the comparative example 1 are as follows:

4.1 Properties

The emulsion disclosed by the invention is milky white, appropriate in viscosity, fine, smooth and uniform, refreshing, moisturizing, non-sticky, good in spreading property, rapid in absorption, comfortable in skin feel and aromatic in smell.

4.2 pH check

Taking the product, and measuring by using pH test paper to obtain the pH value of 6.5-7.0.

4.3 Cold-Heat test

The sun-proof milk is packaged in a transparent cosmetic bottle and refrigerated in a refrigerator at 4 ℃ for one month for observation without layering phenomenon. The emulsion is placed in a constant temperature box at 55 ℃ for 24 hours, and the phenomena of layering, emulsification and odor change of the emulsion are avoided.

4.4 centrifugal test

The sunscreen emulsion is packaged in a test tube with a plug and centrifuged at 3000r/min for 20min, and no layering phenomenon occurs.

4.5 Room temperature standing experiment

The sunscreen emulsions prepared in examples 1,2, 3 and comparative example 1 were placed in a cream bottle and left to stand at room temperature for 6 months without any delamination, any change in feeling after use, and any change in odor.

4.6 irritation test and allergy test

The back of the white mouse was cut to remove hairs, and the sun block prepared according to examples 1,2, 3 and comparative example 1 was applied to the cut-out portions, respectively, and compared with the non-applied portions, no irritation or allergic reaction was observed.

A proper amount of the sunscreen emulsion prepared in the examples 1,2, 3 and the comparative example 1 is applied on the hand surface of a volunteer (20-73 years old, 90 people), and no redness, eruption or foaming phenomenon appears after 30 minutes.

4.7 investigation of comprehensive effects of sunscreen emulsion

The efficacy of the sunscreen emulsions prepared in examples 1,2 and 3 was evaluated by the following test feeling. Adopting a civil survey grading method, selecting 90 volunteers of 20-73 years old as trial objects, dividing the trial objects into three groups at will, and respectively applying the sunscreen emulsion prepared in the examples 1,2 and 3 to each part of the body for two months. The using effects of the ingredients are divided into 5 points: the score of 5 is the highest score, which represents good and very satisfactory; 4, the division is better; 3 is acceptable; when the amount is less than 3 points, the results are not acceptable. The average score of each item is as follows. The results are shown in Table 1

Table 1 comprehensive effect investigation

The sunscreen creams prepared in examples 1,2 and 3 were all easy to apply evenly and did not whiten. The sunscreen lotion prepared in the comparative example 1 is difficult to spread, and the whitening condition after spreading is serious, so that no volunteer is willing to apply the sunscreen lotion prepared in the comparative example 1 for a sunscreen effect experiment.
