摘要:Personal care compositions, such as oral care and skin care compositions containing a flavor/perfume system comprising one or more coolants. The pleasant cool sensation provided by a coolant is enhanced in terms of quicker onset, greater intensity, impact or longer duration, which improves appeal and acceptability of the compositions to consumers.

摘要:Copper(II) bromide mediated oxidation of acylated enol and use of the reaction in the synthesis of α,β-unsaturated or α-bromo ketones or aldehydes are disclosed. The method provides an efficient and practical process for manufacturing dehydrohedione (DHH) and many other versatile α,β-unsaturated or α-bromo ketones or aldehydes in large scales to avoid using precious metal compounds.
