Property Insights of 1,1,3,3-Tetramethyl-1,3-dioctyldisiloxane

The XLogP value of 8.1342 indicates that 1,1,3,3-Tetramethyl-1,3-dioctyldisiloxane is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 9.2 Ų, 1,1,3,3-Tetramethyl-1,3-dioctyldisiloxane exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, 1,1,3,3-Tetramethyl-1,3-dioctyldisiloxane has 0 hydrogen bond donor(s) and 1 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
