Živjo,

Namesto macerata uporabite kakšno drugo olje (mandljevo, olivno…), bo rezultat zelo podoben, samo brez vanilijevega vonja 🙂

Zdravo,

Seveda, oboje lahko uporabite. Nerafinirano karite maslo bo končnemu izdelku dalo nekaj vonja, če vas ne moti, potem ni nobenih težav 🙂

Zanima me nekaj glede karitejevega in kakavovega masla. Imam namreč nerafinirano karitejevo maslo in rafinirano kakavovo maslo. Ju lahko vseeno uporabim?

Hvala in lep dan želim!
Katja

P.S.: 1ml= pribl. 33 kplj. ~ po šolsko 1ml=20 kplj. Vendar ni tako, kar sigurno sama že veš, saj je vse odvisno od eter.olja, gostote oz. molekul samega eter.olja.

Vnaprej se zahvaljujem za vse info in še veliko lepih in veselih trenutkov pri ustvarjanju želim.

Zdravo,

Ja, blogi o domačih kremah za sončenje tudi meni malo dvignejo pritisk. Ker ponavadi temeljijo na predpostavki “naravno = varno” in “sintetično, nenaravno = nevarno”. Pa svet žal ni tako črno-bel 🙂 V svoji začetni navdušenosti sem tudi sama doma izdelala kremo za sončenje (še celo na UV svetlobi sem jo “testirala”), pa sem s tem početjem kljub vsemu nehala, ko sem se v tematiko bolj poglobila.
Se pa tudi jaz veselim novih raziskav s področja UV zaščite! 🙂

Zdravo,
tale zgornji komentar sem napisala že kar nekaj časa nazaj, ko sem pred tem prispevkom naletela na kar nekaj blogov o izdelovanju domačih sončnih krem, ki so me kar malo razjezile. Svojo jezo sem definitivno zlila na neprimeren način in na neprimeren prispevek. Zato se iskreno opravičujem. Hvala za napisano literaturo, UV filtri so sigurno sestavine, na katerih bo potrebno narediti še veliko študij, da bomo vedeli kaj in kako…

Absolutno se strinjam, da je potrebno navajati vire informacij. Tale zapis je bil mišljen kot en hiter pregled problematike, saj bi se o vsakem podnaslovu dalo napisati razširjen prispevek s pripadajočimi referencami.
Tule so torej znanstveni članki, iz katerih so bili črpani podatki o kemičnih filtrih, navedene so tudi reference, ki se tičejo problematike kontaktnega dermatitisa in draženja kože – še en problem organskih UV filtrov, o katerem še nisem spregovorila. Če do kakšnega izmed njih na Fakulteti za farmacijo ni dostopa, se lahko potrudim, da vam pošljem pdf.
Bi pa v prihodnje prosila za malo bolj kulturen nivo izražanja.
