摘要:
Formulations for cosmetical or pharmaceutical use contain an antioxidant in encapsulated form and a cosmetically or pharmaceutically acceptable carrier. The antioxidant is selected from carbon bridged hindered phenoles, ester bridged hindered phenoles, amide bridged hindered phenoles, lactones of hindered phenoles, sterically hindered oxylamines and sterically hindered hydroxylamines. The encapsulated antioxidant is of high activity and suitable to protect a further active ingredient, e.g. oxidizable natural substances, vitamins, fragrances, and extracts from plants fungi, algae or animals, from premature degradation, especially when coencapsulated together with the ingredient. The formulations are useful inter alia for the preparation of a cosmetical or pharmaceutical skin care or skin delivery formulation, injectable solution, infusion solution, eye drop, drinking solution, a dietary or enriched food, an oral care formulation, drinking gargles, in-halants, or as a food additive.
摘要:
In an apparatus (12) for controlling a pressure in a fuel inflow line of a motor vehicle, a shutoff valve (20) and a pressure limiting valve (21) are arranged in a connection (19). The connection (19) is arranged between an inflow junction (16) which leads to the inflow line and an outflow junction (17) which is led into a fuel container. The pressure limiting valve (21) opens above a first pressure and throttles the flow of the fuel through the connection (19). The shutoff valve (20) closes above a second pressure, the second pressure being higher than the first pressure. This ensures that, when a fuel delivery unit is at a standstill, the pressure in the inflow line does not exceed the first pressure and that, during operation of the delivery unit, the pressure in the inflow line can rise above the second pressure and an internal combustion engine of the motor vehicle is supplied sufficiently with fuel.
