The sun-blocking and moisturizing composition is suitable for sensitive skin, has a touching-melt texture, can form a compact and soft residual film on a skin surface and enable active components to be absorbed better by the skin.

The invention discloses an organic sunscreen composition and application thereof, and belongs to the technical field of cosmetics and skin-care products. The organic sunscreen composition is preparedfrom the following raw materials of ethyl hexyl methoxycinnamate, C12-15 alcohol benzoic acid ester, lauryl sarcosine isopropyl ester, octocrilene, bis-ethylhexoxyphenol methoxyphenyl triazine, octylpolymethylsiloxane, ethyl hexyltriazinone, diethylamino hydroxybenzoyl hexyl benzoate, isodecyl neopentanoate, and butyl methoxydibenzoylmethane. The organic sunscreen composition has the characteristics that ultrasonic absorbents at different wave bands are contained, so that the good sunscreen effect is realized; the compatibility is good, and the freshening degree is high; when a sunscreen product containing the organic sunscreen composition is used, the skin is comprehensively protected, and the pleasant skin feel is provided; the organic sunscreen composition can be applied into cosmeticsor skin-care products, such as sunscreen gels, sunscreen sprays, sunscreen creams, and colorful makeup with sunscreen effect.

The invention discloses perfume and a preparation method thereof. The perfume is prepared from denatured ethanol, daily essence, water, ethylhexyl methoxycinnamate, butyl methoxydibenzoylmethane and ethylhexyl salicylate. In the present invention, the preparation method comprises the following steps: preparing denatured ethanol and daily essence according to a certain ratio and raw materials, so auser can conveniently configure specific perfume; mixing denatured ethanol, daily essence, water, ethylhexyl methoxycinnamate, butyl methoxydibenzoylmethane and ethylhexyl salicylate according to a ratio of 80:15:4.7:0.034:0.033:0.033 to obtain the perfume. The use is extremely convenient, meanwhile, the perfume is stored for a long time, the fragrance is stronger and more durable, the precisionof the perfume is purer in the mode of filtering and mixing liquid, mass production of the perfume by producers can be facilitated, and the operation process is extremely simple and convenient.
