Patent ID: 7959935

Claim:
A simulated vernix composition comprising a continuous lipid phase consisting essentially of physiologic lipids, and a hydratable water phase of simulated cells in the absence of a protein component and in which the cell component of native vernix is replaced by synthetic structures that perform the hydration functions of cells, the simulated cells dispersed in the lipid phase simulating vernix, the hydratable water phase capable of retaining greater than about 65% w/w water of the total composition, the composition in a hydrated film form having a water vapor transmission rate that is between about 85% of the transmission rate through a substantially highly permeable film and about 5% of the transmission rate through a substantially highly occlusive film by a modified ASTM E96E procedure B, and having up to about 38% evaporative water loss from 0 h to 0.5 hr, and up to about 8% evaporative water loss from 0.5 hr to 3 hr.
