Abstract

"PROCESSO PARA PREPARAçãO DE GéIS". A presente invenção refere-se à formação de um creme e gel usando um biopolímero, tal como um poliidroxialcanoato (PHA), um polilactídeo (PLA), um polilactídeoglicolídeo (PLGA) e um poli glicosídeo (PGA), ou um seu derivado, em uma forma látex com a adição de um ligante, que é geralmente uma entidade química anfifílica. Um domínio hidrofóbico da entidade química anfifílica interage com pelo menos um biopolímero formando um complexo solúvel em água, enquanto o domínio hidrofílico da entidade química anfifílica mantém o complexo solúvel em suspensão em uma solução aquosa, que após próprio aquecimento torna-se um gel ou um creme. Como resultado, um gel ou creme versátil é criado com diferentes composições e texturas que são obtidos baseado na natureza do ligante usado e a razão de biopolímeros e ligante(s).
