[0035] Examples 1-4 and Comparative Examples 1-5: Preparation of sunscreen composition

[0036] Weigh the composite sunscreen according to the ratio in Table 1, heat the composite sunscreen to 40-50°C until it is completely transparent and free of particles; homogenize the dissolved composite sunscreen and emulsifier at a speed of 7000-8000rpm, After 4-6 minutes, no obvious particles can be observed, which is recorded as the oil phase; the pH regulator is weighed according to the ratio in Table 1 and fully mixed and dissolved until there are no obvious particles, and the pH value is adjusted to 7.2-7.6, and then add anti-corrosion The agent, active substance and water are fully mixed and dissolved, and the pH is adjusted to 7.2-7.6, which is recorded as the water phase; the water phase is slowly added to the oil phase, and stirred and emulsified at a speed of 350-450rpm; the emulsified oil phase, Homogenize the water phase at a speed of 6000-8000rpm for 1-3 minutes. Observe th...

Abstract

The invention discloses a composite sun-screening agent, which is characterized by being prepared from the following ingredients in parts by weight: 0.5 to 3 parts of bis-ethylhexyloxyphenol methoxyphenyl triazine, 5 to 8 parts of 2-ethylhexyl4-methoxycinnamate, 3 to 5 parts of octocrilene, 1 to 5 parts of hexyl diethylbenzoyl benzoate, 1 to 5 parts of ethylhexyl triazone and 5 to 10 parts of zincoxide. Through the addition of the specific content and specific kinds of composite sun-screening agents into the composition, a prepared sun-screening composition has a high SPF value; the skin feeling is fresh and cool; the use feeling is good; no burden exists on the skin, so that the problem of excessive greasy feeling due to excessive addition of the existing chemical sun-screening agent canbe solved; meanwhile, the problem of burden on the skin due to excessive addition of the existing physical sun-screening agent can also be solved. The preparation method has the advantages that the preparation process is simple; green effect and safety are realized; good industrial application prospects are realized.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a composite sunscreen, a sunscreen composition composed of it and a preparation method thereof. Background technique [0002] In recent years, people have paid more attention to ultraviolet protection. Excessive ultraviolet rays are most obvious to the skin of the human body. Long-term and repeated exposures can cause actinic keratosis (photokeratosis) of the skin and mucous membranes, manifested in exposed parts ( Such as forehead, cheeks, nose tip, lips, eyelids, conjunctiva) with single and multiple plateau-shaped thickening of keratinized layers. Therefore, the sunscreen market has become one of the fastest growing market segments in my country's daily chemical industry. [0003] At present, there are many sunscreen products on the market, but the existing sunscreen products can achieve a high SPF value, but they have obvious advantages and disadvantages. Chemical sunscreens are add...
