Abstract: Disclosed are multi-staged acrylic based core-shell polymers comprising a linear core polymer and at least one subsequently polymerized shell polymer. At least one of the subsequently polymerized shell polymers is crosslinked. The core-shell polymers surprisingly provide desirable rheological, clarity, and aesthetic properties in aqueous surfactant containing compositions, particularly at low pH. The multi-staged acrylic base core-shell polymers can be included in at least one phase of a multi-phase personal care, home care, health care, and institutional and industrial care composition to impart phase stability thereto.

Abstract: This invention relates to A bioadhesive composition comprising two or more essentially excretable, essentially non-degradable polymer backbones, wherein the polymer backbones are crosslinked, said crosslink being degradable in a mammal, said cross-linked bioadhesive composition having an average bioadhesion factor showing bioadhesion equivalent to at least about 100 g s. The concept is to build a hydrogel that demonstrates bioadhesion to a mucosal surface that is crosslinked by a degradable linkage such as disulfide for use inside the body.
