Problems solved by technology

Both sunscreen and sunscreen lotion are emulsion bases that are prone to deterioration and corruption, and it is difficult to achieve waterproof and water-resistant effects; sprays refer to preparations that do not contain propellants and are sprayed into mist by means of the pressure of a manual pump. In terms of dosage form, the sunscreen spray is easy to carry and use. It is sprayed directly on the skin in mist form. It does not need to be applied by hand, does not stick to hands, and can reduce losses at the same time. However, there are many problems in the existing sunscreen spray. The sunscreen agent is directly dispersed in the spray. , when in direct contact with the skin, there will be an irritating reaction. At the same time, because the general sunscreen is an emulsion matrix, which is suitable for microbial growth, it is easy to deteriorate and corrupt, and it is difficult to achieve waterproof and water resistance.
Moreover, cream sunscreens are prone to whitening after application; the texture is generally thicker, and the skin will feel heavy after application

Abstract

The invention discloses a SOD containing liposome sun-blocking and moisturizing spray and a preparation method thereof and belongs to the technical field of cosmetic production. The problem that a sun-blocking and moisturizing agent is directly dispersed in the spray in an existing product, skin irritation reaction is caused, the sun-blocking and moisturizing emulsion easily deteriorates and decays and the sun-blocking and moisturizing spray is poor in waterproof and water-resistant effect is solved. The preparation method includes the following steps that lecithin, cholesterol and the like are added to an anhydrous ethanol to be dissolved, and then rotary evaporation is performed to obtain a film; a freeze-drying excipient and a preservative are dissolved in a PBS buffer, then beta-dextran is added to prepare a water mixture; the water mixture is added to the film, stirring is performed, water bath stirring is performed after the film is completely dissolved, and then ultrasonic treatment is performed to obtain a crude liposome; the crude liposome is subjected to freezing and thawing treatment, SOD is added, ultrasonic treatment is performed to obtain refined SOD liposome suspension liquid; filling is performed to obtain the product. The preparation method can be used for preparation of the SOD containing liposome sun-blocking and moisturizing spray.
