Description
[technical field]
The present invention relates to the formula improving desquamation situation, relate to the constituent that effectively can improve the dandruff especially.
[background technology]
Dermatitis means the disease of chafing.The patient of dermatitis, except usual along with except vesicle, erythema, transudate, exfoliation erythra or incrustation pathological changes in appearance, more may occur that play is itched hard to bear phenomenon.Therefore, dermatitis, for quality of life and the physically and mentally healthy negative effect produced, should not be underestimated.
The horny layer of skin is positioned at health outermost layer, and major function is for isolating extraneous harmful substance and being held in body by moisture content.The time that normal skin needs about one month just can be ripe gradually, and come off in the mode that naked eyes cannot be discovered, with metabolism aging cutin layer.Generally speaking, when the relative humidity of environment is less than 50 %, keratodermatitis water content is just lower than 10 %, and therefore horny layer loses pliability, and then drying comes off and causes skin injury, inflammation.General dermatitis, can by temporary transient partial smearing steroid ointment as hydrocortisone (Cort. S), Cutivate (Cutivate), reduce the stimulation (such as use the cleaning supplies of nonirritant or have a bath with clear water as far as possible) in environment simultaneously, and effectively obtain alleviation.
The dandruff is extremely common and irritating scalp problems, although can not health risk, the scurf that the scalp itch be accompanied, head come off such as to increase at the symptom, but often causes social obstacle with inter personal contact and puzzlement.The possible cause of the dandruff comprises: seborrheic dermatitis, chronic eczema, some chemical substance (as hair dye, send out carving or send out cured) the contact dermatitis, the fungal infection (tinea capitis) that cause, do not wash hair for a long time.In addition, pressure, nervous, nutritional disorder, do not have enough sleep, overwork, be also considered to accelerate the dandruff and formed.
With general place skin unlike, the scalp sites of dandruff patient, within average two to seven days, namely form the bulk white scurf that naked eyes are obviously visible.Seborrheic dermatitis is for causing the No.1 reason of dandruff generation, and the dandruff is also for scalp leaks the most common symptom of fat atopic dermatitis patient.The origin cause of formation of known this type dandruff, excessively grows relevant with the fungus (i.e. scurf sporeformer comprises Malassezia furfur and Malassezia globosa) on skin.Point out according to research, producing the position of the dandruff, the bacterium amount of scurf brood cell bacterium can up to 1.5 to 2 of normal level times.These funguses are understood the triglyceride in metabolism sebum and form oleic acid (oleic acid), after oleic acid infiltrates through the horny layer of epidermis, the chafing of some body constitution comparatively sensitive subjects will be lured into, and then the Homeostasis of Interference angle cell plastid, cause abnormal reaction that comes off, thus produce the dandruff.
Some contains the shampoo that tar (tar) becomes to divide, all effective for the dandruff suppressing scalp chronic eczema and seborrheic dermatitis to be caused, but most " anti-bits shampoo " then poor effect.The composition of commercially available anti-bits shampoo mainly contains: but gram more than that frustrates (ketoconazole), ZPT (zinc pyrithione, ZP), salicylic acid (salicylic acid), selenium sulfide (selenium sulfide, SeS
2), ciclopirox olamine (ciclopirox olamine, CPO), Piroctone Olamine (piroctone olamine), pyrithione salt (pyridinethione salts), can see, for example US 4,835,148 and US 6,538, person disclosed by 011.
Have academic research to show, at any position of health, all visible fat is present between horn cell, and it is so-called to be formed " bricks and mortar " structure of (fragment of brick and mud).The fat molecule vertical with skin surface is in (parallel fatty rete) arranged in parallel each other, and between each row fat molecule, form the interval of wide-narrow-wide (4 nm-2 nm-4 nm), this kind of kenel effectively to prevent in body moisture content outwards penetrating (Bouwstra JA et al., J Lipid Res:39:186-196).If this is destructurized or change, prevent the function of water evaporates from namely obviously declining.Some chemical substance known can destroy the normal-fat layer arrangement mode in horn cell gap, such as emulsifying agent inferior and interfacial agent, makes the drying of skin hydropenia or becomes responsive, even red and swollen, desquamation.
Research is separately had to point out (Xu Yaling, Taiwan National Cheng Kung University clinical pharmacy institute Master's thesis, 2007): continue every day to smear human sebum on normal nude mouse skin, skin surface will produce inflammatory response, and scurf increases, percutaneous moisture content scatters and disappears in one week increases 3-4 doubly, and 1/3rd when epidermis water content is reduced to normal.After stopping smearing human sebum, namely skin recovered normal shielding (barrier) function gradually in five days.In addition, smear unsaturated fatty acid and also can reduce skin barrier function, the structure of epidermal hyperplasia and corneocyte gap fat molecule is changed, releiving of dermatitis is harmful on the contrary.
Anti-bits mode known at present mostly focuses on rinse scalp or kills scurf sporeformer; But these class methods are still " taking stopgap measures " and " do not effect a permanent cure ".Therefore, being necessary to develop one can help scalp to recover normal function of shielding and character is gentle, the medicament or the constituent that are even applicable to newborn baby.
