“…The interaction between the hydrophobic groups is too weak to deform the structure, which resembles the structure formation of hydrophobic silica in silicone oil (13). Similar results were obtained for some fumed silica suspensions with 7.5 wt% silica content (14,15).…”

“…When the shear stress reaches a maximum the "bonds" between the particles begin to break down, and thereafter there is a steady decrease in the shear stresses. A similar maximum has been observed by many other researchers [16][17][18] . The same argument also explains why the shear stress is higher when the shear rate is decreasing.…”

The use of cone and plate rotational rheology to characterize the flow properties of concentrated dispersion and extrusion methods to determine the rheological properties of pastes have become established rheometric techniques. Direct comparison between the results obtained from the two techniques has not previously been demonstrated. In this article the results of such a comparison using established experimental methods and associated analysis are reported. It is found that for most samples investigated the difference in the calculated values of shear stress at a shear rate of 5/s is ≤10%. Data for a series of slurries, composed of various solid fractions of lime waste, are reported over a shear rate of 0-10/s. The computed results for two techniques are shown to be, within the experimental error, identical over this shear rate range.

“…For example, to improve the stability of silicone oil emulsions, large amounts of surfactants including silicone surfactants, stabilizers, electrolytic suspensions, etc. have been employed [18][19][20][21][22][23]. But, the uniformity was still poor to cope with the stability problem of emulsions resulting in poor product quality.…”

Synopsis Silicone oils have wide range of applications in personal care products due to their unique properties of high lubricity, non‐toxicity, excessive spreading and film formation. They are usually employed in the form of emulsions due to their inert nature. Until now, different conventional emulsification techniques have been developed and applied to prepare silicone oil emulsions. The size and uniformity of emulsions showed important influence on stability of droplets, which further affect the application performance. Therefore, various strategies were developed to improve the stability as well as application performance of silicone oil emulsions. In this review, we highlight different factors influencing the stability of silicone oil emulsions and explain various strategies to overcome the stability problems. In addition, the silicone deposition on the surface of hair substrates and different approaches to increase their deposition are also discussed in detail.
