Abstract:
The present invention relates to a process for producing hydrogenolysis products of polyhydric alcohols with a good selectivity and a high yield, as well as hydrogenolysis catalysts used in the production process. The present invention provides (1) a process for producing a hydrogenolysis product of a polyhydric alcohol which includes the step of reacting the polyhydric alcohol with hydrogen in the presence of a catalyst containing a copper component, wherein the catalyst is a catalyst (A) containing the copper component, an iron component and an aluminum component, or a catalyst (B) containing the copper component and a silicon component; and (2) a hydrogenolysis catalyst for polyhydric alcohols which includes a copper component, an iron component and an aluminum component, and (3) a hydrogenolysis catalyst for polyhydric alcohols which includes a copper component and a silicon component.
Abstract:
Provided are a hair bleach composition, hair dye composition and a hair treatment additive having excellent bleaching power, capable of dyeing the hair with a bright and good color, and less damaging to the hair and less irritating to the scalp. Described specifically, they are a two-part hair bleach composition, which contains (a) a nitrogenous compound represented by the following formula (1) or (2): or salt thereof, or (A) a nitrogenous compound having a solubility parameter logP in octanol/water ranging from -1 to 4 and a hydrogen peroxide remaining ratio of from 5 to 90%, or salt thereof, (b) an oxidizing agent, and optionally (c) an alkali agent and, after mixing, has a pH of from 7.5 to 12; a two-part hair dye composition comprising (a) or (A), (b) and (c) and further (d) an oxidation dye or direct dye; and an additive used therefor.
