Problems solved by technology

[0003] Tea polyphenols have the functions of removing harmful free radicals from the body, improving the body's comprehensive immunity, improving sub-health status, anti-radiation, regulating the stomach, lowering blood fat, lowering blood pressure, anti-aging, beauty and beauty, and weight loss. Therefore, it has been widely used in medicine , food and other fields, but due to its very unstable properties after extraction, the existing products containing tea polyphenols often have the defects of unstable active ingredients and easy inactivation, so they cannot effectively exert their biological activity effect

Embodiment 1

[0023] Example 1 is used to illustrate the preparation process of tea polyphenol oil suspension preparation.

[0024] An oil suspension formulation is prepared by the following steps:

[0025] (1) Mix 1.5 kg of aluminum stearate, 1 kg of stearic acid and 96.5 g of paraffin oil at 150 °C at a speed of 1000 rpm and stir until the system is clear and transparent, then cool down to 25 °C;

[0026] (2) Mix 5kg of tea polyphenols with the product of step (1) at 25°C, and stir at a speed of 300rpm for 20min;

[0027] (3) Grinding the product of step (2) with grinding beads with a diameter of 0.25 mm in the grinding bead homogenizer, the grinding conditions are: stirring at 1000 rpm, circulating 5 times, to obtain milky white tea polyphenol oil mixture Suspension preparation.

preparation example 1-3

[0029] Preparations 1-3 are used to illustrate the emulsions provided by the present invention.

[0030] Emulsion 1-3 was prepared according to the raw material content provided in Table 1 by the following steps:

[0031] Heat emulsion B component and emulsion C component to 70°C and stir at 1000rpm for 15min to obtain emulsion mixture 1, cool emulsion mixture 1 to 25°C and mix with emulsion A component, stir at 600rpm for 3min Get lotion. The tea polyphenol oil suspension preparation used is the tea polyphenol oil suspension preparation prepared in Example 1.

Abstract

The invention relates to a long-lasting emulsion capable of effectively reducing ultraviolet ray absorption. The main components of the emulsion are a sun-screening agent and a tea polyphenol oil suspension formulation, wherein every 100 g of emulsion contains the following components in quantities: an emulsion component A: 5-45 g of the tea polyphenol oil suspension formulation; an emulsion components B: 1-3 g of lanolin alcohol, 3-10 g of Vaseline, 1-5 g of montmorillonite, 0.5-2 g of span 60, 0.5-5 g of beewax, 1-5 g of stearic acid and 3-7.5 g of iso-octyl p-methoxycinnamate; an emulsion components C: 0-5 g of propylene glycol, 0.2-1 g of monoethanolamine and the balance of water. The emulsion provided by the invention adopts tea polyphenol as the main active component. As the tea polyphenol is added into the emulsion in the form of the tea polyphenol oil suspension formulation, the stability of the active components is improved. Therefore, the emulsion provided by the invention is long-lasting and can effectively reduce the absorption of the skin to ultraviolet rays.

Description

technical field [0001] The invention relates to the field of daily chemical industry, in particular to an emulsion with high durability and effective reduction of ultraviolet absorption. Background technique [0002] When the skin is exposed to ultraviolet rays, it will damage the epidermal cells; activate tyrosinase, accelerate pigment synthesis, destroy the skin's moisturizing function, make the skin dry, damage the elastic fibers in the dermis, and cause fine lines. Under strong exposure, it can also cause skin inflammation and burns. When there are abnormalities, it will become pigmented skin cancer, etc. Therefore, how to effectively and permanently reduce the skin's absorption of ultraviolet rays is always a problem that needs to be faced and solved in the research and development of skin care products. [0003] Tea polyphenols have the functions of removing harmful free radicals from the body, improving the body's comprehensive immunity, improving sub-health status,...
