Embodiment 1

[0035] A long-acting moisturizing slow-release microsphere applied to barrier cream. The interior of the slow-release microsphere is filled with porous hydrogel and moisturizing skin care essence, and the surface is sealed with a photolytic polymer. Under the action of light, the porous hydrogel The expansion and extrusion of the glue slowly releases the moisturizing skin care essence inside the slow-release microspheres.

[0036] The hydrating skin care essence includes by weight: 3.5 parts of shea butter, 5 parts of squalane, 13 parts of hyaluronic acid, 2 parts of vitamin E, and 9 parts of n-butanol.

[0037] The preparation process of the slow-release microspheres is:

[0038] (1) Dissolve galactose accounting for 65% of the total mass of galactose in water, heat it to 168°C for 5.5 hours, and after the reaction, collect the product by vacuum filtration and freeze-drying for 13 hours to obtain template microspheres; Add the balls into distilled water, ultrasonically dispe...

Embodiment 2

[0047] A long-acting moisturizing slow-release microsphere applied to barrier cream. The interior of the slow-release microsphere is filled with porous hydrogel and moisturizing skin care essence, and the surface is sealed with a photolytic polymer. Under the action of light, the porous hydrogel The expansion and extrusion of the glue slowly releases the moisturizing skin care essence inside the slow-release microspheres.

[0048] The hydrating skin care essence includes by weight: 2 parts of shea butter, 4 parts of squalane, 10 parts of hyaluronic acid, 1 part of vitamin E, and 8 parts of n-butanol.

[0049] The preparation process of the slow-release microspheres is:

[0050] (1) Dissolve galactose accounting for 60% of the total mass of galactose in water, heat to 165°C for 5 hours, after the reaction, collect the product under reduced pressure and suction filtration, freeze-dry for 12 hours to obtain template microspheres; Add in distilled water, ultrasonically disperse f...

Embodiment 3

[0059] A long-acting moisturizing slow-release microsphere applied to barrier cream. The interior of the slow-release microsphere is filled with porous hydrogel and moisturizing skin care essence, and the surface is sealed with a photolytic polymer. Under the action of light, the porous hydrogel The expansion and extrusion of the glue slowly releases the moisturizing skin care essence inside the slow-release microspheres.

[0060] The hydrating skin care essence comprises by weight: 5 parts of shea butter, 6 parts of squalane, 15 parts of hyaluronic acid, 3 parts of vitamin E, and 10 parts of n-butanol.

[0061] The preparation process of the slow-release microspheres is:

[0062] (1) Dissolve galactose accounting for 70% of the total mass of galactose in water, heat to 170° C. for 6 hours, and after the reaction, collect the product under reduced pressure and suction filtration, and freeze-dry for 14 hours to obtain template microspheres; Add in distilled water, ultrasonical...

Abstract

The invention relates to the technical field of cosmetics, and discloses a long-acting moisturizing sustained-release microsphere applied to a make-up base and a preparation method of the long-acting moisturizing sustained-release microsphere in order to solve the problems that an existing make-up base is poor in moisturizing and skin care persistence and a sustained-release condition of sustained-release microspheres in the make-up base is harsh. The sustained-release microsphere is internally filled with porous hydrogel and essence; the surface of the sustained-release microsphere is subjected to hole sealing by adopting a photolysis polymer, and the essence in the sustained-release microsphere is slowly released under the expansion and extrusion function of the porous hydrogel under the action of illumination; the essence comprises the following components in parts by weight: 2-5 parts of shea butter, 4-6parts of squalane, 10-15 parts of hyaluronic acid, 1-3 parts of vitamin E and 8-10 parts of n-butyl alcohol. The sustained-release microsphere is filled with the porous hydrogel which swells under an illumination condition, in addition, the porous hydrogel is full of the essence, a polymer which is cracked under the illumination condition is adopted for carrying out the hole sealing on the sustained-release microspheres, so that long-acting sustained release of the essence in the sustained-release microsphere is finally realized, and a relatively good moisturizing and skin-care effect is achieved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a long-acting moisturizing slow-release microsphere applied to a barrier cream and a preparation method thereof. Background technique [0002] The barrier cream is mainly to protect the skin and reduce the irritation caused by adverse factors to the skin; in addition, the barrier cream also has the function of isolating ultraviolet rays, because it contains sunscreen, and the barrier cream is the closest layer of protective barrier to the skin. During the day, people usually It takes a long time to make up. If the skin is dry, the adhesion of the make-up will be reduced. On the one hand, it will easily cause the appearance of the cosmetic effect to deteriorate. On the other hand, the skin will deteriorate due to long-term water shortage. Existing After the solvent volatilizes, it becomes a simple dry coating layer, and the skin comfort is poor. Therefore, it is of great signifi...
