Abstract
The invention relates to matrix and layer compositions comprising a first polymer. The matrix and layer compositions are useful in the delivery of bioactives. In particular, the matrices and layers may have advantageous properties including mechanical properties and protection of bioactives and may also provide for pH-dependent release of a bioactive.
