摘要:
Pyrogenically prepared, surface-modified, structurally modified titanium dioxides and pyrogenically prepared, surface-modified, structurally modified titanium dioxide mixed oxides are prepared by structurally modifying and then surface modifying the titanium dioxide or titanium dioxide mixed oxide. The titanium dioxides can be used to produce sunscreen formulations.
摘要:
Surface-modified, pyrogenically prepared titanium dioxides coated with silicon dioxide are prepared by spraying the pyrogenically prepared titanium dioxides coated with silicon dioxide with a surface-modifying agent and then tempering them. They can be used in sun protection formulations.

摘要:
Pyrogenically prepared, structurally modified titanium dioxides or pyrogenically prepared, structurally modified titanium-dioxide mixed oxides are prepared by the titanium dioxides being treated with a ball mill and optionally being subsequently ground. They may be employed in sunscreen formulations.
摘要:
Surface-modified zinc-titanium mixed oxides are produced by treating zinc-titanium mixed oxides with a surface-modifying agent. They may be used for the production of sunscreen preparations.

Carrier based on granules produced from pyrogenically prepared silicon dioxides. The use of granules produced from pyrogenically prepared silicon dioxides as carriers for substances including foodstuffs additives, such as dyestuffs, antioxidants, preservatives, emulsifiers, gelling agents, thickeners and binders, stabilizers, alkalis, acids, salts, antilumping agents, flavour intensifiers, sweeteners, aromas; feedstuff additives; chemical intermediates and plant protection agents.
摘要:
Hydrophobic pyrogenic silica doped with potassium by means of aerosol is prepared by reacting a pyrogenic silica doped with potassium by means of aerosol with a surface-modifying agent. It can be used as a filler in silicone rubber.

摘要:
The invention relates to a method of producing finely divided oil-in-water emulsions which comprise oil, water and at least one emulsifier, which comprises a step A) producing a mixture 2, which has oil, water, at least one emulsifier and at least one cosmotropic substance, by mixing oil, water, at least one emulsifier and at least one cosmotropic substance, where the phase inversion temperature PIT2 of this mixture (Winsor IV system) is less than the phase inversion temperature PIT1 of a mixture 1 (Winsor IV system) which has no cosmotropic substances and otherwise the same composition as mixture 2, and subsequently a step B) addition of a diluent to mixture 2 to convert this mixture to an emulsion 3, where the amount of added diluent is chosen so that the resulting emulsion 3 at a pregiven temperature is not in the Winsor IV phase region.
