潤膚(fu)露(lu)基(ji)本常(chang)識
潤膚露是一種液態霜類化(hua)妝(zhuang)品(pin),有良(liang)好的潤膚作(zuo)用(yong),也有調濕(shi)效(xiao)果,早期的乳(ru)液是水包(bao)油(you)型乳(ru)狀液,多采用(yong)鉀皂做乳(ru)化(hua)劑,但在存放(fang)過程中會變稠,不易從瓶中倒出,近年采用(yong)十二(er)醇硫酸、二(er)乙醇胺鹽或非離子型乳(ru)化(hua)劑,可制(zhi)得穩定性(xing)很好的潤膚露。
潤(run)膚(fu)露類化(hua)妝品又稱蜜類化(hua)妝品,是水(shui)包油(you)型(xing)的(de)(de)乳(ru)(ru)化(hua)劑,含水(shui)量(liang)(liang)在10%~80%左右,具(ju)有(you)(you)一定的(de)(de)流動性,形(xing)狀頗似蜜,故而得名(ming)。潤(run)膚(fu)露含水(shui)量(liang)(liang)較大,能為皮(pi)(pi)膚(fu)補(bu)(bu)(bu)充(chong)(chong)水(shui)份(fen)(fen)。乳(ru)(ru)液(ye)還含有(you)(you)少量(liang)(liang)的(de)(de)油(you)分,又可(ke)(ke)以滋潤(run)皮(pi)(pi)膚(fu)。乳(ru)(ru)液(ye)具(ju)有(you)(you)三個方面(mian)的(de)(de)作用,去污、補(bu)(bu)(bu)充(chong)(chong)水(shui)份(fen)(fen)、補(bu)(bu)(bu)充(chong)(chong)營養。去污是指(zhi)乳(ru)(ru)液(ye)可(ke)(ke)以代替潔面(mian)劑清(qing)除(chu)面(mian)部污垢。補(bu)(bu)(bu)充(chong)(chong)水(shui)份(fen)(fen),由(you)于乳(ru)(ru)液(ye)中(zhong)含有(you)(you)10%~80%左右的(de)(de)水(shui)份(fen)(fen)。因(yin)此,可(ke)(ke)以直接給(gei)皮(pi)(pi)膚(fu)補(bu)(bu)(bu)充(chong)(chong)水(shui)份(fen)(fen),使皮(pi)(pi)膚(fu)保持濕潤(run)。補(bu)(bu)(bu)充(chong)(chong)營養,由(you)于潤(run)膚(fu)露中(zhong)含有(you)(you)少量(liang)(liang)油(you)分,當臉上皮(pi)(pi)膚(fu)發緊時(shi),乳(ru)(ru)液(ye)中(zhong)的(de)(de)油(you)分可(ke)(ke)以滋潤(run)皮(pi)(pi)膚(fu),使皮(pi)(pi)膚(fu)柔軟。
