Cold process formulation is attracting a lot of attention at the moment, mainly due to the many practical benefits there are to be had. When you remove heating and cooling cycles it reduces energy use, shortens batch times and removes the risk of degrading heat-sensitive ingredients. For many production teams it also means simpler, more flexible processing.

In surfactant chemistry, we discuss four broad types based on their ionic charge. The first three are: “anionics,” which provide a negative charge in solution; “cationics,” which provide a positive charge in solution; and “non-ionics,” which do not ionize in solution and thus carry no charge. The fourth type is the “amphoterics,” which possess both a negative and positive charge, for example:
R.N⁺(R²)2.COO־
This example features a quaternary nitrogen group (N⁺R₄) with a positive charge and an acyl group (COO־) with a negative charge within the same molecule. This is balanced at neutral pH and is known as the “zwitterionic form.”Continue reading
