  A transfer hydrogenation process for forming vicinal diols by hydrogenating 1,2-dioxygenated organic compounds using alcohols as the reducing agent instead of the traditional H2 gas. The transfer hydrogenation is carried out under milder conditions of temperature and pressure than is typical for ester hydrogenation with H2. The milder conditions of operation provide benefits, such as lower operating and capital costs for industrial scale production as well as savings in product purification due to the avoidance of by-products from exposure of reaction mixtures and products to high temperatures.

  一种通过使用醇作为还原剂而不是传统的氢气，在较温和的温度和压力条件下，通过氢化1,2-二氧化有机化合物形成邻二醇的转移加氢过程。操作的较温和条件提供了诸如工业规模生产的较低运营和资本成本以及由于避免将反应混合物和产物暴露在高温下而节省产品纯化成本的好处。

  One or more esters selected among an ester of a C 2-10 fatty acid with a polyhydric alcohol, an ester of a monobasic hydroxy acid with a mono- or polyhydric alcohol, and an ester of a polybasic acid with a mono- or polyhydric alcohol are incorporated into a cosmetic hair preparation comprising a crystalline compound and a solvent in which the compound dissolves. Due to this, the crystalline compound is inhibited from crystallizing/precipitating at low temperatures and the preparation can give an improved use feeling during use.
