DELIVERY OF ORAL CARE SUBSTANCES

摘要

Disclosed is a hydrophilic silicone composition comprising an oral care substance. The composition is based on polysiloxanes having a high water-uptake capability. An aqueous solution or dispersion of the oral care substance can be soaked into the polysiloxane, whereby the resulting composition shows favorable release characteristics. The use of hydrophilically modified polysiloxanes, possibly in conjunction with unmodified hydrophobic polysiloxanes, allows for the convenient production of desired shapes, advantageously based on a dental imprint. The hydrophilic modification of the polysiloxane is particularly by including a hydrophilic vinyl monomer, particularly an alpha-olefinic soap, into the composition prior to curing.
