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:
Pulverulent mixture comprising hydrogen peroxide and hydrophobized, pyrogenically prepared silicon dioxide powder, wherein the hydrophobized silicon dioxide powder has a methanol wettability of at least 40 and is present to the extent of less than 9 wt. %, based on the total weight, and the content of hydrogen peroxide, based on the total weight, is between 10 and 50 wt. % It is prepared by a process in which hydrophobized silicon dioxide powder with a methanol wettability of more than 40 is treated with an aqueous hydrogen peroxide solution at temperatures of not more than 70° C. It can be used in detergents, in cleaning compositions and in skin and hair treatment compositions.
摘要:
Shower oil gels are disclosed containing up to 70 wt. % of one or more oil-soluble surfactants, 5 to 70 wt. % of one or more oil components, 0.1 to 25 wt. % of one or more pyrogenic silicas and optionally further cosmetic or pharmaceutical auxiliary substances, additives and/or active compounds.
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.
摘要:
Pulverulent cosmetic formulation comprising at least one hydrophobized silicon dioxide powder, at least one cosmetically relevant constituent and at least 50 wt. % of water, based on the total amount of the formulation, characterized in that the hydrophobized silicon dioxide powder has a tamped density of at least 70 g/l, determined in accordance with DIN EN ISO 787-11.
