Description
Technical field
The invention relates to a kind of natural sun-prevention compositions, specifically is about a kind ofly being used for adding to cosmetics, the spf value of cosmetics is had the natural sun-prevention compositions of potentiation ability, belonging to the cosmetics additive field.
Background technology
The major function of sun care preparations is exactly sun-proof, or anti-ultraviolet (Ultraviolet Radiation) radiation is to the harmful effect of human skin.Ultraviolet is called for short UVR; It is a kind of Non-ionizing radiation; Wavelength is between 100～400nm; Usually call short wave ultraviolet (UVC) to wavelength at the ultraviolet of 100～290nm, the ultraviolet of wavelength between 290～320nm is called ultraviolet B radiation (UVB), and the ultraviolet of wavelength between 320～400nm is called long wave ultraviolet (UVA).Because short wave ultraviolet (UVC) is absorbed by atmospheric ozone layer fully; Ultraviolet from solar radiation has only ultraviolet B radiation (UVB) and long wave ultraviolet (UVA) just can reach earth surface, so the main effect of sun care preparations is embodied on the protection effect to UVB and UVA.Estimating the height of the sun-proof function of a kind of sunscreen product, mainly is to see SPF (sun protection coefficient, Sun Protection Factor, size SPF).SPF is defined as the minimum erythema dose that uses the sun care preparations protecting skin, and (minimal Erythema Dose is MED) with the ratio that does not use the minimum erythema dose (MED) of sun care preparations protecting skin.Spf value is big more, and cosmetic product anti-ultraviolet UVB section is to the damage ability of skin just stronger (Xu Huihui, Su Jin, Song Weimin, Zhou Hua, Wu Lichang, Zhou Shiwei.Result's comparison is measured in SPF Instrument measuring and human trial.Shanghai preventive medicine magazine, Vol 14, NO.7).
In order to reach ideal spf value, in the sunscreen product prescription, will add certain component of sun, and component of sun is of a great variety, roughly be divided into (Wang Fengling, Zhang Yingfeng, nightstool rivers such as ultraviolet light screener, UV absorbent, natural sun-prevention agent.The classification of sunscreen, the mechanism of action and evaluation.Chemical education, 2008, (6)).
Some inorganic particulates that ultraviolet light screener normally adds in sunscreen are like physical sunscreen agent such as titanium dioxide, zinc oxide.These tiny particles can form the barrier layer at skin surface, through reflection, scatters ultraviolet skin are played a protective role.Advantage is that stability is high, and consumption does not receive any restriction of country.Shortcoming be transparent feel poor, be prone to be deposited as white layer and come off at skin surface.And use and too much can stop up pore, influence sweat gland secretion, even cause dermatosis etc.
UV absorbent plays anti-sunlight function through in sunscreen, adding a certain amount of ultra-violet absorption material; Mainly be chemical sunscreen, for example para-amino benzoic acid derivant, o-aminobenzoa derivant, cinnamate derivative, salicylic acid esters, Benzophenones chemical compound, camphor derivatives, methane Derivatives etc.The molecular energy of these absorbent absorbs ultraviolet energy, discharges with forms such as heat energy or visible lights, thereby reduces the injury to skin.Advantage is low, the easy prescription of price, and sales volume is bigger on market, and the product transparency of processing is high, good absorbing effect.Shortcoming is that skin is had certain zest, possibly cause inflammation, side effect such as allergy, and kind and addition all receives the strictness restriction of national health department.
The natural sun-prevention agent is extracted from natural plants.The natural sun-prevention agent can effectively absorb ultraviolet, remove oxygen-derived free radicals.Because the ultraviolet light absorbers has certain chemical stimulation property, and ultraviolet light screener some can stop up pore, skin nursing is all had harmful effect, so, add some natural sun-prevention components, can reduce the overall stimulation property of sunscreen product greatly.China is applied to extracting solution such as Aloe, Fructus Cucumidis sativi in the sunscreen product at present.In addition, some Chinese herbal medicine such as the Flos Sophorae Immaturus, Rhizoma Coptidis, Flos Carthami etc. not only have stronger anti-sunlight function, can also play skin protection, whiten, treat effect such as dermatitis, therefore have higher using value.The sun-proof interval of natural sun-prevention agent is big, the sensitization rate is low, safe and effective, has broad application prospects.
