Alkyl Polyglycosides a cikin Kayayyakin Kulawa na Keɓaɓɓu

A cikin shekaru goma da suka gabata, haɓakar albarkatun ƙasa don samfuran kulawa na mutum ya ci gaba a manyan fannoni uku:

(1) tausasawa da kula da fata

(2) Ma'auni masu inganci ta hanyar rage abubuwan da aka samu da kuma abubuwan da ba su dace ba.

(3) dacewa da muhalli.

Dokokin hukuma da buƙatun mabukaci suna ƙara haɓaka sabbin ci gaba waɗanda ke bin ƙa'idodin tsari da dorewar samfur. Wani bangare na wannan ka'ida shine samar da alkyl glycosides daga mai kayan lambu da kuma carbohydrates daga tushen sabuntawa. Haɓaka fasahar kasuwanci yana buƙatar babban matakin iko akan albarkatun ƙasa, halayen halayen da yanayin sarrafawa don biyan buƙatun ingancin kayan kayan kwalliya na zamani da kuma samar da su a farashi mai ma'ana. A fannin kayan shafawa, alkyl glucoside wani sabon nau'in surfactant ne tare da abubuwan da ba na ionic da anionic na al'ada ba. Har zuwa yau, mafi girman rabon samfuran kasuwanci sune masu tsaftacewa da C8-14 alkyl glycosides ke wakilta, waɗanda ke nuna halayen fata da gashin gashi. C12-14 alkyl polyglycoside yana aiki azaman emulsifier a cikin takamaiman tsari kuma musamman a cikin microemulsions da kuma nazarin aikin C16-18 alkyl polyglycoside a matsayin tushen emulsifying o / w wanda aka haɗu da barasa mai mai.

Don tsarin tsabtace jiki, sabon surfactant na zamani dole ne ya sami dacewa mai kyau tare da fata da mucous membranes. Gwaje-gwajen dermatological da toxicological suna da mahimmanci don tantance haɗarin sabon surfactant da ƙira mafi mahimmanci don gano yiwuwar haɓakar ƙwayoyin rai a cikin Layer basal na epidermal. A baya, wannan shine tushen da'awar tawali'u. A lokaci guda, ma'anar tawali'u ya canza da yawa. A yau, ana fahimtar tawali'u a matsayin cikakkiyar daidaituwa na surfactants tare da ilimin lissafi da aikin fata na mutum.

Ta hanyar daban-daban dermatological da biophysical hanyoyin, da physiological effects na surfactants a kan fata da aka yi nazari, farawa daga saman fata da kuma ci gaba zuwa zurfin Layer na basal Kwayoyin ta hanyar stratum corneum da shãmaki aiki.A lokaci guda, m majiyai. , irin su ji na fata, an rubuta su ta harshen taɓawa da kwarewa.

Alkyl polyglycosides tare da C8 zuwa C16 alkyl sarƙoƙi suna cikin ƙungiyar masu raɗaɗi mai laushi don ƙirar tsabtace jiki. A cikin cikakken binciken, an kwatanta daidaituwar alkyl polyglycosides a matsayin aiki na sarkar alkyl mai tsabta da kuma digiri na polymerization.A cikin gwajin gwaji na Duhring Chamber da aka gyara, C12 alkyl polyglycoside yana nuna matsakaicin dangi a cikin kewayon m haushi ects yayin da C8, C10 da C14,C16 alkyl polyglycoside suna haifar da ƙananan ƙima. Wannan yayi daidai da abubuwan lura tare da sauran nau'ikan surfactants. Bugu da ƙari, haushi yana raguwa kaɗan tare da ƙara darajar polymerization (daga DP = 1.2 zuwa DP = 1.65).

Kayayyakin APG tare da tsayin sarkar alkyl gauraye suna da mafi kyawun daidaituwa gabaɗaya tare da mafi girman adadin dogon alkyl glycosides (C12-14) .An kwatanta su da ƙari na hyperethoxylated alkyl ether sulphates mai laushi sosai, amphoteric glycine ko amphoteric acetate, da kuma furotin mai laushi. -fatty acid akan collagen ko alkama proteolytic abubuwa.

Abubuwan da aka gano na dermatological a cikin gwajin wankin hannu na flex yana nuna matsayi iri ɗaya kamar a cikin Gwajin Chamber na Duhring da aka gyara inda aka bincika tsarin gauraye na daidaitattun alkyl ether sulfate da alkyl polyglycosides ko amphoteric co-surfactants. Koyaya, gwajin wankin hannun hannu yana ba da damar mafi kyawun bambance-bambancen tasirin. Samuwar erythema da squamation za a iya rage ta 20-30 D/o idan a kusa da 25 ° 10 na SLES an maye gurbinsu da alkyl polyglycoside wanda ke nuna raguwar kusan 60%. A cikin tsarin ginawa na tsari, za a iya samun mafi kyawu ta hanyar ƙara abubuwan gina jiki ko amphoterics.
