Um\u00fdvanie dom\u00e1cim mydlom z brav\u010dovej masti je skuto\u010dnou klasikou z \u010dias babi\u010dky. Brav\u010dov\u00e1 mastia poskytuje pevn\u00e9, biele mydlo, ktor\u00e9 skvele \u010dist\u00ed a je ve\u013emi \u00fasporn\u00e9.<\/p>\n\n\n\n
Ke\u010f\u017ee pracujeme s l\u00fahom (NaOH), bezpe\u010dnos\u0165 je prvorad\u00e1.<\/p>\n\n\n\n

Ochrann\u00fd odev: Uistite sa, \u017ee nos\u00edte ochrann\u00e9 okuliare, gumen\u00e9 rukavice a dlh\u00e9 ruk\u00e1vy.<\/p>\n\n\n\n
V\u00fdpary: Pri zmie\u0161an\u00ed s vodou NaOH uvo\u013e\u0148uje \u0161tip\u013eav\u00e9 v\u00fdpary. Nevdychujte ich. Najlep\u0161ie je pracova\u0165 vonku alebo s dokor\u00e1n otvoren\u00fdm oknom.<\/p>\n\n\n\n
\u017diadny hlin\u00edk: Pou\u017e\u00edvajte iba n\u00e1doby vyroben\u00e9 zo skla, nehrdzavej\u00facej ocele alebo odoln\u00e9ho plastu (PP\/HDPE). NaOH koroduje hlin\u00edk!<\/p>\n\n\n\n
Poradie: NaOH v\u017edy prid\u00e1vajte do vody, nikdy nie naopak (nebezpe\u010denstvo striekania!).<\/p>\n\n\n\n
Ingrediencie
Na pr\u00edpravu dobr\u00e9ho mydla na pranie budete potrebova\u0165:<\/p>\n\n\n\n
1000 g brav\u010dovej masti (\u010distej, bez soli a korenia)
330 g studenej vody (najlep\u0161ie destilovanej)
138 g hydroxidu sodn\u00e9ho (granule NaOH z lek\u00e1rne alebo online)*<\/p>\n\n\n\n
(Pozn\u00e1mka: Toto zodpoved\u00e1 koncentr\u00e1cii l\u00fahu pribli\u017ene 4\u20135 %. \u010cist\u00e9 mydlo na pranie by malo obsahova\u0165 ve\u013emi m\u00e1lo prebyto\u010dn\u00e9ho tuku, aby nezanech\u00e1valo mastn\u00e9 \u0161kvrny na oble\u010den\u00ed.)<\/p>\n\n\n\n
Podrobn\u00fd n\u00e1vod<\/p>\n\n\n\n
Odv\u00e1\u017ete studen\u00fa vodu v odmerke odolnej vo\u010di teplu.<\/p>\n\n\n\n
Presne odv\u00e1\u017ete NaOH v samostatnej n\u00e1dobe.<\/p>\n\n\n\n
Pomaly prid\u00e1vajte NaOH do vody za st\u00e1leho mie\u0161ania. Kvapalina sa zna\u010dne zahreje a spo\u010diatku sa zakal\u00ed. Mie\u0161ajte, k\u00fdm sa \u00faplne nerozpust\u00ed.<\/p>\n\n\n\n
Roztok l\u00fahu umiestnite na bezpe\u010dn\u00e9 miesto (napr. k otvoren\u00e9mu oknu) a nechajte ho vychladn\u00fa\u0165 na pribli\u017ene 40 \u2013 50 \u00b0C.<\/p>\n\n\n\n
Nechajte ju pomaly roztopi\u0165 na spor\u00e1ku na miernom ohni.<\/p>\n\n\n\n
Ke\u010f je \u00faplne tekut\u00e1, odstavte hrniec z oh\u0148a. Tuk by mal tie\u017e dosiahnu\u0165 teplotu pribli\u017ene 40 \u2013 50 \u00b0C. (V ide\u00e1lnom pr\u00edpade by roztok l\u00fahu a tuk mali ma\u0165 pribli\u017ene rovnak\u00fa teplotu.)<\/p>\n\n\n\n
Pou\u017eite ty\u010dov\u00fd mix\u00e9r a zmes rozmixujte na najni\u017e\u0161om stupni. Striedajte kr\u00e1tke intervaly mixovania a ru\u010dn\u00e9 mie\u0161anie.<\/p>\n\n\n\n
Po nieko\u013ek\u00fdch min\u00fatach zmes zhustne. Ke\u010f bude ma\u0165 konzistenciu mierne tekut\u00e9ho pudingu a ty\u010dov\u00fd mix\u00e9r zanech\u00e1 na povrchu \u010d\u00edru stopu, mydlo je pripraven\u00e9 na nalievanie do formy.<\/p>\n\n\n\n
Formou nieko\u013ekokr\u00e1t jemne poklepte o pracovn\u00fa dosku, aby ste odstr\u00e1nili v\u0161etky vzduchov\u00e9 bubliny.<\/p>\n\n\n\n
Formu prikryte plastovou f\u00f3liou a zaba\u013ete ju do star\u00e9ho uter\u00e1ka. Mydlo sa samo zahreje (g\u00e9lov\u00e1 f\u00e1za).<\/p>\n\n\n\n
Blok nakr\u00e1jajte na \u013eahko zvl\u00e1dnute\u013en\u00e9 k\u00fasky ostr\u00fdm, ve\u013ek\u00fdm no\u017eom. (D\u00f4le\u017eit\u00e9: Noste rukavice, preto\u017ee mydlo m\u00f4\u017ee by\u0165 st\u00e1le mierne \u017eierav\u00e9!).<\/p>\n\n\n\n
K\u00fasky mydla polo\u017ete na pergamenov\u00fd papier a medzi nimi nechajte ur\u010dit\u00fd priestor na suchom a dobre vetranom mieste.<\/p>\n\n\n\n
Doba vytvrdzovania: Nechajte mydlo vytvrdzova\u0165 aspo\u0148 4 a\u017e 6 t\u00fd\u017ed\u0148ov. Po\u010das tejto doby sa proces zmydelnenia dokon\u010d\u00ed, hodnota pH klesne a mydlo sa stane jemn\u00fdm a pevn\u00fdm.<\/p>\n\n\n\n
Ako sa pou\u017e\u00edva pracie mydlo od babi\u010dky?<\/p>\n\n\n\n
Ako odstra\u0148ova\u010d \u0161kv\u0155n (alternat\u00edva k kry\u0161t\u00e1lov\u00e9mu mydlu): Pred pran\u00edm jednoducho navlh\u010dite mydlo, votrite ho do odoln\u00fdch \u0161kv\u0155n (golier, tr\u00e1va, mastnota) a potom ho vlo\u017ete do pr\u00e1\u010dky.<\/p>\n\n\n\n
Ako prac\u00ed prostriedok: Vytvrdnut\u00e9 mydlo jemne nastr\u00fahajte pomocou kuchynsk\u00e9ho str\u00fahadla. Nastr\u00fahan\u00e9 mydlo sa m\u00f4\u017ee priamo zmie\u0161a\u0165 s pracou s\u00f3dou (uhli\u010ditanom sodn\u00fdm) v pomere 1:1, \u010d\u00edm vznikne vynikaj\u00faci a ekologick\u00fd prac\u00ed prostriedok na biele aj farebn\u00e9 tkaniny.<\/p>\n","protected":false},"excerpt":{"rendered":"
