Description

Sunscreen cosmetic powder material composition

Technical field

The present invention relates to a kind of sun care preparations, it demonstrates high UV shielding properties, and is not clamminess or can not stays white residue, thereby good experience is provided, and they are different from conventional sunscreen, can make on skin and can refine the make-up continuing after cosmetic to repaste to be applied to.

In addition, the present invention relates to the cosmetic composition of the cooperative effect between a kind of use organic uv filter (or organic and inorganic UV sunscreen) and UV isolation effect adjuvant (UV blocking efficacy booster).

Background technology

Recently, along with ozone layer is destroyed by environmental pollution, being exposed to becomes serious problem in ultraviolet.Ultraviolet damages skin usually, for example, and erythema, edema, freckle, skin carcinoma etc.In this case, need exploitation to avoid the product of uv damage for the protection of skin.Particularly, living standard is higher, out of doors during stress-relieving activity (for example skiing, golf and in marine swimming) and during normal activity in production protection skin to avoid the wish of uv damage just stronger.Carried out multinomial research to satisfy the demands of consumers steadily.

Generally speaking, according to wavelength, ultraviolet is divided into 3 zones; UVC 200 and 290nm between scope in, UVB 290 and 320nm between scope in, and in the scope of UVA between 320nm and 400nm.UVC penetrates ozone layer and but arrives the earth surface disappearance.The epidermis of UVB transdermal causes erythema, freckle, edema etc.The corium of UVA transdermal also causes skin aging and skin irritation, causes skin carcinoma, wrinkle, promotion to form melanin etc.

Just as known, the ultraviolet that is exposed to the sun is dangerous, and the public is more and more interested in sunscreen product.Therefore, there is on the market the sunscreen product with multiple daylight sun protection factor (SPFs) and UVA degree of protection (PAs).

Generally speaking, based on the emulsion type, sunscreen product is divided into water-in-oil type and oil-in-water type.The oil-in-water type product has better experience, but water proofing property is relatively poor, yet water-in-oil type product water proofing property is better, but experience is relatively poor.

In order to reach the required high-caliber UV shielding properties of consumer, inevitably to use a large amount of UV screening components.the UV sunscreen (for example mainly comprises inorganic UV sunscreen, titanium dioxide, zinc oxide or zirconium oxide) and organic uv filter is (for example, octyl methoxycinnamate, ethylhexyl salicylate, octocrylene (octocrylene), PAROSOL 1789 (butylmethoxydibenzoylmethane) (BMDBM), ESCALOL 567 (oxybenzone), octyl triazone (octyltriazone), Antisolaire (menthylanthlanilate) or 3, 4 methyl benzylidene camphor (3, 4-methyl benzylidene camphor)).Described organic uv filter is also referred to as chemical sunscreen, and the wave-length coverage that absorbs the UV zone is hindered skin to prevent the UV line loss.Described inorganic UV sunscreen is also referred to as the physical sunscreen agent, and the light in its scattering UV zone is hindered skin to prevent the UV line loss.

Excessive chemical UV sunscreen (that is, organic uv filter) may cause skin irritation and to polytype injury of skin, and based on this reason, most countries has been set limiting the quantity of of consumption.In addition, described organic uv filter is present in the liquid phase with very high viscosity usually, thereby is clamminess.Described organic uv filter uses full-bodied oil as solvent.Therefore, usually, the product that comprises described organic uv filter is made into the form of cream or emulsion agent.Yet, feel that the problem that is clamminess does not solve fully, and the experience of using descends significantly.

Described inorganic UV sunscreen, for example, titanium dioxide, zinc oxide etc., comparatively safe to skin, thereby be the focus that recent people pay close attention to.Yet described inorganic UV sunscreen has high index of refraction in essence, and the white casse that causes white residue to be stayed on skin is unclear, and due to its structural feature, can not provide soft experience when using.

The solid phase sunscreen product of wax has appearred on market using recently.Use these products in the mode that applies with powder puff (puff) on skin.In this case, the use powder puff does not allow the component with these products of hand contamination, thereby, can not stay on hand the sensation that is clamminess.Yet, have limitation on perception issue is clamminess in elimination.

In addition, when normal daily routines, particularly after cosmetic, consumer wants to repeat to apply sunscreen product on skin.Yet, because emulsion or the white phase product of routine is clamminess, when again being coated in conventional products on skin, will destroy original cosmetic after cosmetic.Thereby conventional cosmetics do not allow to refine the make-up.

Summary of the invention

[technical problem]
