We would like to correct the following statement “All previous reports on particle-stabilized emulsions deal with emulsions that have internal phase levels below 70vol%.” made in the introduction of our recent article. Since the publication of our communication, three papers13 describing Pickering w/o and o/w emulsions with different internal phase levels and stabilities, which were not referenced in our paper, have been brought to our attention. Arditty et al.2 describe silicone oil-in-water Pickering emulsions with up to 90 wt % internal phase and water-in-silicone oil Pickering emulsions having internal phase levels of up to 75 wt % stabilized using as received hydrophilic silica particles and silanized hydrophobic silica particles, respectively. Therefore, we should have stated “Reports on particle stabilized w/o emulsions deal with emulsions having internal phase levels of up to 75vol%. However, Arditty et al. reported on the preparation of o/w Pickering-HIPEs with up to 90% internal phase by manual shaking.” Furthermore, we also stated in our communication that “Binks and Lumsdon[11]further stated that particle-stabilized emulsions phase invert between volume fractions of 0.65 and 0.7, which means the major phase becomes the continuous phase.” This statement is correct for the water-in-oil Pickering emulsions described in Ref. 4, however, Binks and Lumsdon1 also provide examples of phase inversion occurring at different oil/water ratios starting from as low as 0.4. We would like to apologize to the authors of papers 13 for not acknowledging their research.
