摘要:
A material for chemical vapor deposition of the present invention contains a precursor composed of a metal compound, and has 100 or less particles having a size of 0.5 μm or more in 1 ml, in particle measurement by a light scattering type submerged particle detector in a liquid phase. A thin film can be prevented from being contaminated by particles even when a highly degradable metal compound is used as the precursor.
摘要:
Provided is a composition for percutaneous administration containing a mixture of polymers forming a surface-segregated film, and (B) an active ingredient. The composition provides excellent percutaneous absorption efficacy of the active ingredient, particularly, a water-soluble active ingredient, has excellent feeling and is convenient to use.
摘要:
Titanium dioxide powder with a greatly decreased volatile moisture content can be obtained by surface treating with titanium dioxide powder with addition of a calcium salt and/or a silane coupling agent, or by a surface treatment by addition of an aluminate together with these surface treatments. A masterbatch containing this titanium dioxide powder is of high quality, having no defect due to foam generation upon high temperature processing.
