Embodiment approach

[0045] As a preferred embodiment of the present invention, the sunscreen synergistic composition comprises the following components in a mass fraction of 100%:

[0046] Tetrahydromethylpyrimidine carboxylic acid 10-13%, Milo leaf / stem extract 30-35% and Chlorella extract 51-58%.

[0047] By further limiting the mass fraction of each component of the sunscreen synergistic composition, the sunscreen synergistic composition has excellent sunscreen synergistic effect and wide formulation applicability.

[0048] According to the second aspect of the present invention, there is also provided a cosmetic composition comprising the above sunscreen synergistic composition and optional additives acceptable in the cosmetic field.

[0049] Here, "optional" means that the additive may or may not be added, which can be determined according to the actual efficacy required.

[0050] In view of the advantages of the above-mentioned sunscreen synergistic composition, the cosmetic composition ha...

Abstract

The invention provides a sunscreen synergistic composition, a cosmetic composition and a preparation method thereof, and relates to the technical field of cosmetics. The sunscreen synergistic composition is prepared by synergistically matching a specific amount of ectoine, a leaf/stem extract of myrothamnus flabellifolia and a chlorella extract, can cover various mechanisms of preventing UV from damaging skin, and has the advantages of high efficiency, durability, safety, sunscreen and synergy; meanwhile, the sunscreen synergistic composition is water-soluble, has weak skin permeability, can stay on the surface and epidermal layer of the skin for a long time, and provides a long-acting sunscreen synergistic effect; and in addition, the components of the sunscreen synergistic composition are all biological sources, have no stimulation risk, and have high safety. The invention also provides the cosmetic composition, which comprises the sunscreen synergistic composition and an optional additive acceptable in the field of cosmetics. The invention also provides the preparation method of the cosmetic composition.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a sunscreen synergistic composition, a cosmetic composition and a preparation method thereof. Background technique [0002] Skin science studies have shown that sun exposure is one of the important factors in skin aging, and intense UV exposure may cause skin cancer. Sunlight contains ultraviolet rays with a wavelength of 200-400nm. The 2015 version of the "Safety Technical Specification for Cosmetics" can divide ultraviolet rays into short-wave ultraviolet UVC (200-290nm), medium-wave ultraviolet UVB (290-320nm) and long-wave ultraviolet UVA (320 nm) according to its wavelength range. -400nm). Due to poor penetration, UVC is blocked by the ozone layer and cannot reach the ground. Therefore, the ultraviolet rays that cause damage to the skin are usually referred to as UVB and UVA. UVB radiation has a shorter wavelength and higher energy, and can penetrate the skin to a depth...
