Natural aqueous film-forming composition based on a pair of starches

Abstract

The object of the invention relates to a water-based film-forming composition and to the respective film for the coating of oral solid forms and for rigid and soft capsules, comprising: acetylated pregelatinized starch containing amylose in an amount ≥50% by weight, and acetyl groups in an amount ranging from 0.5% to 2.5% by weight based on the weight of the starch; acetylated non-pregelatinized starch containing amylose in an amount ≥50% by weight, and acetyl groups in an amount ranging from 0.5% to 2.5% by weight based on the weight of the starch. This composition is characterized in that it is free of or does not require lubricants, in particular is talc-free.
