Dnes je u\u017e modernej\u0161ie mydlo tekut\u00e9, preto\u017ee sa s\u00a0n\u00edm jednoduch\u0161ie nar\u00e1ba. Neobchytk\u00e1va ho cel\u00e1 rodina, ale jednoducho sa nad\u00e1vkuje rovno do dlane. Hne\u010f je roztopen\u00e9, pomaly k\u00a0nemu netreba ani vodu. Pred vyn\u00e1jden\u00edm tekut\u00e9ho mydla sa pou\u017e\u00edvalo mydlo klasick\u00e9. Bolo trv\u00e1cnej\u0161ie ako mydlo tekut\u00e9, preto\u017ee sa rozp\u00fa\u0161\u0165alo po mal\u00fdch d\u00e1vkach a\u00a0\u013eudia spotrebovali tak jedno alebo dve mydl\u00e1 za rok. S\u00a0pr\u00edchodom tekut\u00fdch mydiel sa to v\u0161ak zmenilo.\tAk\u00e1 bola hist\u00f3ria mydla?Mydlo sa spom\u00edna u\u017e na hlinen\u00fdch tabu\u013ek\u00e1ch, ktor\u00e9 poch\u00e1dzaj\u00fa z\u00a0roku 2500 p. n. l. Je to naozaj dlh\u00e1 doba. Dnes si ani nevieme poriadne predstavi\u0165, \u017ee by sme si mydlo za\u010dali vyr\u00e1ba\u0165 doma. No, aj tak\u00e9 gazdinky s\u00fa medzi nami. V\u00a0minulosti to bola mo\u017eno be\u017en\u00e1 prax. Ale vo vzdialenej\u0161ej minulosti sa mydlu dostalo len vo vy\u0161\u0161\u00edch vrstv\u00e1ch. Poddan\u00ed k\u00a0nemu nemali pr\u00edstup. Mydlo sa robilo v\u00a0ka\u017edej dom\u00e1cnosti, preto\u017ee sa pou\u017e\u00edvalo na v\u0161etko. Na um\u00fdvanie riadov, na pranie, na um\u00fdvanie \u013eud\u00ed, ale aj dl\u00e1\u017eok. Vznikali r\u00f4zne triky na to ako zisti\u0165, \u010di je u\u017e mydlov\u00fd roztok z\u00e1sadit\u00fd alebo nie a\u00a0podobne.\tL\u00ed\u0161ilo sa starovek\u00e9 mydlo od toho dne\u0161n\u00e9ho?Samozrejme, \u017ee l\u00ed\u0161ilo. M\u00f4\u017eeme v\u0161ak poveda\u0165, \u017ee bolo v\u00fd\u017eivnej\u0161ie ako teraz. Dne\u0161n\u00fd kozmetick\u00fd priemysel vyr\u00e1ba mydlo tak, \u017ee nech\u00e1 zreagova\u0165 hydroxid sodn\u00fd alebo hydroxid draseln\u00fd (pod\u013ea toho, \u010di chc\u00fa tekut\u00e9 alebo pevn\u00e9 mydlo) s\u00a0tukmi. Dnes asi naj\u010dastej\u0161ie s\u00a0palmov\u00fdm tukom, preto\u017ee je lacn\u00fd a\u00a0r\u00fdchlo, jednoducho sa z\u00edskava. Aby mydlo bolo tak\u00e9 ako si predstavujeme sa do\u0148ho prid\u00e1vaj\u00fa r\u00f4zne \u010fal\u0161ie chemik\u00e1lie, o\u00a0ktor\u00fdch nem\u00e1me ani potuchy a\u00a0ich n\u00e1zvy by n\u00e1m ani ni\u010d nehovorili. Pri be\u017enej v\u00fdrobe mydla, pri saponifik\u00e1cii, teda pri reakcii tukov a\u00a0hydroxidu vznik\u00e1 mydlo a\u00a0prirodzen\u00fd glycer\u00edn. Preto\u017ee glycer\u00edn je dos\u0165 vz\u00e1cny, odober\u00e1 sa z\u00a0mydla a\u00a0d\u00e1va sa do inej kozmetike, v\u00a0ktorej sa prirodzene nenach\u00e1dza. A\u00a0mydlo bez glycer\u00ednu u\u017e nie je mydlom v\u00a0pravom slova zmysle. Toto mydlo v\u00e1s s\u00edce prevonia (preto\u017ee s\u00fa tam chemick\u00e9 v\u00f4ne) a\u00a0vy\u010dist\u00ed, ale va\u0161u poko\u017eku vysu\u0161\u00ed, preto\u017ee v\u00a0\u0148om ch\u00fdba prirodzen\u00fd glycer\u00edn. A\u00a0to bez oh\u013eadu na to, z\u00a0ak\u00e9ho oleja je vyroben\u00e9 mydlo. Preto potrebujeme pou\u017e\u00edva\u0165 kr\u00e9my. Mydlo na\u0161u poko\u017eku vysu\u0161\u00ed, ale keby sme si vyrobili mydlo ako za star\u00fdch \u010dias, tak by sme tak\u00fdto probl\u00e9m nemali.                                                                                                                                                                                                                                                                                                                                                                                        4.5\/5 - (11 votes)        "},{"@context":"https:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Mydlo \u2013 jednoduch\u00e9 alebo zlo\u017eit\u00e9?","item":"https:\/\/www.jameslh.sk\/mydlo-jednoduche-alebo-zlozite\/#breadcrumbitem"}]}]
