at.algebraic topology - Extending a property of commutative algebras to C infinity algebras

If A is a commutative algebra and B is an X- algebra, then the tensor product AotimesB is an X-algebra (so for example, ComotimesLie is a Lie algebra). This is seen using the language of operads. Let Com be the commutative operad. Since Com(n) is a one dimensional vector space for every n, tensoring Com with an operad O doesn't change the operad O.



Does a similar thing hold true for a Cinfty algebra? That is, if A is a Cinfty algebra, is AotimesB an Xinfty algebra?



I'm still trying to familiarize myself with the language of operads, and perhaps the question can be made more precise in that language, where the infinity version of an operad is cofibrant resolution of the operad.
