Sun-screening composition and preparation method and application thereof

Abstract

The invention relates to the technical field of cosmetics, in particular to a sun-screening composition and a preparation method and application thereof. The sun-screening composition is prepared from solid inorganic sunscreen 20%-85%, organic sunscreen 10%-80% and a dispersant 1%-40%. The preparation method includes the steps of mixing, vacuum mixing, homogenizing and detection, and the prepared sun-screening composition can serve as the effective ingredient of a sun-screening product. The sun-screening composition has the advantages of being easy to disperse, high in stability, high in sun protection factor and flexible in formula combination. The preparation method of the sun-screening composition has the advantages of simple process and high production effect.

Description

technical field

[0001] The invention relates to the technical field of cosmetics, in particular to a sunscreen composition and its preparation method and application. Background technique

[0002] With the intensification of air pollution, the development and research of sunscreen will become the focus of researchers and consumers both now and in the future. Among them, sunscreen products are convenient and quick to use, and are not restricted by occluders, which are people's first choice for sunscreen.

[0003] Today, there are two main types of sunscreens used in the preparation of sunscreens on the market: inorganic sunscreens and organic sunscreens. Inorganic sunscreens are generally solid products containing titanium dioxide or zinc oxide. In actual production, in order to disperse the solid inorganic sunscreen evenly, it is necessary to grind the solid inorganic sunscreen to a powder state. However, grinding the solid inorganic sunscreen is not only a cumbersome proces...

Embodiment 1

[0040] The sunscreen composition of the present embodiment is made up of the raw material of following weight:

[0041] 30g of nano-titanium dioxide, 67g of isoamyl p-methoxycinnamate, and 3g of polyhydroxystearic acid, wherein the diameter of nano-titanium dioxide is 10nm-100nm.

[0042] The preparation method of above-mentioned sunscreen composition is as follows:

[0043] Weigh 30g of nano-titanium dioxide, 67g of p-methoxyisoamyl cinnamate, and 3g of polyhydroxystearic acid, and put the weighed nanometers of p-methoxyisoamyl cinnamate and polyhydroxystearic acid into the reactor Stir evenly to obtain the first mixture; then evacuate the reactor to -0.1Mpa, and at the same time, pump the above-mentioned weighed nano-titanium dioxide into the reactor from the bottom of the reactor while vacuuming, keep the reactor in a vacuum state, and then stir Until the titanium dioxide is completely wet; then, continue to stir homogeneously in the high-pressure mode of the reactor; afte...
