Abstract We construct a continuous family of algebras over a field of characteristic zero with slow codimension growth bounded by a polynomial of degree 4. This is achieved by building, for any real number α ∈ ( 0 , 1 ) a commutative nonassociative algebra A α whose codimension sequence c n ( A α ) , n = 1 , 2 , …  , is polynomially bounded and lim ⁡ log n ⁡ c n ( A α ) = 3 + α . As an application we are able to construct a new example of a variety with an infinite basis of identities.
