These bialgebras can be described as deformed bosonizations $R#_{\\xi} H$ of a pre-bialgebra $R$ by $H$ with a cocycle $\\xi$. Here we describe the behavior of $\\xi$ in the case when $R$ is f.d. and thin i.e. it is connected with one dimensional space of primitive elements. This is used to analyze the arithmetic properties of $A$. Meaningful results are obtained when $H$ is cosemisimple.
