The present invention relates to organo(poly)siloxanes modified by phosphates (including alkali metal salts thereof or the like) suitable as a component of cosmetics, and to a process for the manufacture of organo(poly)siloxanes modified by phosphates (including alkali metal salts thereof or the like) comprising reacting an organo(poly)siloxane having a group HO--(R.sup.4 O).sub.q --R.sup.5' --OR.sup.6).sub.r -- in its molecular chain, wherein R.sup.4 -R.sup.6 are alkylene groups, with an oxyhalogenated phosphorus; and further reacting it with an alkaline solution. These phosphate-modified organo(poly)siloxanes can stably emulsify silicone oils commonly used as cosmetic raw materials, irrespective of temperatures, and exhibit excellent compatibility with polar components and good foaming capability, so that they are suitable as a component of cosmetics such as skin cosmetics, skin detergents, hair cosmetics, hair detergents, and the like.
The invention relates to organosilanes and organopolysiloxanes which contain 2-oxazolidinone groups, where the oxazolidinone group is linked by the ring carbon atom C-4 or C-5 via a spacer to the silane or siloxane and the spacer is connected via a hydrolysis-stable Si--C bond to the silane or siloxane, their use as surface-active substances and also their use for preparing organosilanes and organopolysiloxanes containing amino or carbamido groups.
The present invention provides a compacted and consolidated aluminum-based alloy material which has been obtained by compacting and consolidating a rapidly solidified material having a composition represented by the general formula: Al.sub.a Ni.sub.b X.sub.c wherein X is one or two elements selected from Zr and Ti and a, b and c are, in atomic percentages, 87.5.ltoreq.a.ltoreq.92.5, 5 .ltoreq.b.ltoreq.10, and 0.5.ltoreq.c.ltoreq.5; and a production process comprising melting a material of the above composition; quenching and solidifying the resultant molten material into powder or flakes; compacting, compressing, forming and consolidating the powder or flakes by conventional plastic working. The consolidated material of the present invention has. elongation (toughness) sufficient to withstand secondary working, even when secondary working is applied. Moreover, the material allows the secondary working to be performed easily while retaining the excellent properties of its raw material.
