A general method for evaluating scalping from pastes by polymers has been applied to scalping from a mint-flavored toothpaste. The quantities of six key volatile flavorants - d-limonene, 1,8-cineole, menthone, menthol, (-)carvone, and cinnamaldehyde-scalped from the toothpaste by a given polymer are determined by multiple extraction head space gas chromatography (MEHSGC). Relative extents of scalping by the polymer films are also measured gravimetrically. The scalping characteristics of the following polymers are compared: HDPE, MDPE, VLDPE, LLDPE, an ethylene vinylacetate copolymer (EVA), an ethyleneacrylic acid copolymer (ESCOR 5100), and two zinc ionomers (IOTEK 4000, EX 906). The data obtained in this study indicate that the relative extents of scalping of the eight different polymer films studied increase in the following order: MDPE < LLDPE ∼VLDPE < HDPE < ESCOR 5100 < EVA < IOTEK 4000 < EX 906 Thus, the extent of scalping is not at all related to the crystallinity of the polymer. It is, on the other hand, very much related to the presence of oxygen containing comonomer and to ionomerization. Additionally, scalping is shown to be very inhomogeneous (quantities scalped are not in proportion to quantities found in toothpaste).
