Abstract

Předkládané řešení se týká koloidní směsi obsahující polystyrénové nanočástice o velikosti alespoň 400 nm, přičemž koncentrace nanočástic v koloidní směsi nepřesahuje více jak 1,0 % hmotn. Výše uvedenou koloidní směs lze použít jako aktivní koloidní směs v kosmetických přípravcích, jako je např. krém nebo sprej na opalování. V dalším provedení lze použít koloidní směs jako ochranou látku proti nežádoucímu UV záření i pro neživé komponenty.
