Hair Conditioner: heated water phase and heated oil phase
We have worked a new Hair Conditioner recipe (heated water phase, heated oil phase, and cool down phase) through lab batches and then small production batches of around 7.0 Kg. The Stability Tests and Challenge Tests have been good. We are now planning to scale up.My question: we have always added the heated water phase into heated oil phase. The heated water phase is signifantly bigger than the heated oil phase. With the existing equipment we are planning to use, it would be easier to add the heated oil phase into the heated water phase.(1) What would be the consequences of adding the heated oil phase into the heated water phase?(2) Any work arounds?(3) What type of equipment are people usually using for this type of formulation?ThanksRegards,Mike -

(1) assuming it’s O/W, as most conditioners are, none; oil into water is the most typical way these products are manufactured(3) on a large scale (100 kg upwards), a hemispherical reactor with a contra-rotating scrape-wall mixer and a shear mixer is the best piece of kit for the job
