[0047] A sunscreen cosmetic with waterproof and anti-perspiration properties, its excellent water resistance comes from a unique polyurethane dispersion polymer, which is a polyurethane dispersion, chemical name polyurethane-11, trade name C200, produced by German Kechuang company . Due to the unique lipophilic group structure on the main chain of the polyurethane polymer, it has high-efficiency lipophilicity, can wrap various oil esters, and can especially stabilize sunscreen agents that are difficult to emulsify.

[0048] In order to form the form of "polyol-polyurethane-sunscreen" when the components are compounded, the present invention divides the components into 10 items when configuring the components to ensure the stability of ...

Abstract

The invention relates to a sunscreen cosmetic with waterproof and antiperspirant properties, which comprises three components of A to form a polyol water phase, and components of the B phase: 1-10 parts of water, 1-5 parts of phenylbenzimidazole sulfonic acid, ammonia 0.5-2.0 parts of methyl propanol; three components of C form the polyurethane sunscreen core, and finally form a composite structure to achieve the best waterproof effect. The present invention is an oil-in-water cream-like product, which has refreshing and not heavy skin feeling, but has better water-proof and sweat-proof properties. It has high sun protection index and PA protection value, which can reach SPF50 and PA+++, and can protect the skin for a long time. The sunscreen used has strong photostability and high safety. While resisting ultraviolet rays, it is not easy to generate free radicals and reduce the burden on the skin. It adds plant anti-allergic and anti-inflammatory ingredients and raw materials that resist visible light and infrared light to prevent inflammation and light. Aging, prevent erythema and pigmentation caused by sun exposure, improve the protection efficiency of sunscreen products, and truly achieve full-band sun protection.

Description

technical field [0001] The invention belongs to the field of cosmetics, and relates to a sunscreen skin care product, in particular to a waterproof and sweat-resistant full-band sunscreen skin care product. Background technique [0002] Sunscreens act as sunscreens through inorganic or organic active ingredients. Inorganic sunscreen ingredients are usually inorganic substances such as zinc oxide and titanium oxide, which can reflect and scatter ultraviolet radiation; organic sunscreen ingredients are usually OMC (octylmethoxycinnamate) and oxybenzone, which can absorb ultraviolet radiation and convert radiation energy into into heat energy. Many sunscreens protect the skin from both types of ultraviolet rays (UVA, UVB). UVA and UVB cause different damage to the skin. In addition to cosmetic problems, UV rays can cause many more problems, the most serious being skin cancer! From another point of view: it works through two mechanisms of light reflection and absorption. In...
