Industrial mixers for body lotions, hand creams and after-sun products. Lower viscosity than face creams, faster cycle times. SS316L, vacuum emulsifying.

Key Takeaways

Body lotions are lighter and faster than face creams: typically 1,000–10,000 cps, with a full cycle in roughly two to four hours.
Because viscosity is lower, circulation is easier — an RS top-entry machine handles most lotions without the external loop an RX provides.
Cooling rate still decides the final texture. A scraped-wall agitator and a jacketed vessel give you a cooling curve you can repeat batch after batch.
Fragrance goes in at low temperature. Adding it above roughly 40 °C loses the top notes you are paying for.
Cycle time, not vessel size, is usually the constraint on a lotion line — plan on two batches per shift rather than one big one.

What you're making

Body lotions, hand creams, after-sun, baby care — these are lighter emulsions than face creams, typically water-in-oil or oil-in-water with lower viscosity and faster cycle times.

Typical capacity: 100L — 2000L
Typical viscosity: 1,000 – 10,000 cps

PROCESS

How to make it on our machines

Heat phases → combine under vacuum with high-shear homogenizer → cool under continuous agitation → add fragrance and actives → discharge. Cycle time 2–4 hours typical.

Why lotions run faster than creams

A body lotion is a lighter emulsion than a face cream: less wax, less butter, more water. At 1,000–10,000 cps it flows readily, which means the agitator does not fight the batch and heat transfers faster through the jacket. In practice a full cycle — heat, combine, homogenise, cool, dose, discharge — lands in the two-to-four-hour range rather than the longer cycles heavier creams need.

The practical consequence is that throughput is usually limited by how many cycles you can run in a shift, not by how much the vessel holds. Two batches at 500 L often beat one at 1,000 L, because the heating and cooling stages dominate the cycle and they do not scale linearly with volume.

Getting the texture consistent

The difference between a lotion that feels elegant and one that feels watery is usually droplet size and cooling rate, not the formula. Homogenising under vacuum gives you small, uniform droplets; the subsequent cooling sets the structure. If cooling is left uncontrolled, the same formula can come out glossy one day and dull the next.

A wall scraper matters more than it looks. It keeps product moving across the heat-transfer surface instead of letting a stagnant layer insulate the batch, which is what makes cooling both faster and repeatable.

Which layout suits a lotion

RS covers most of this ground. Its top-entry homogenizer emulsifies inside the vessel and the vessel tilts to discharge, so emptying a low-viscosity product is quick and cleaning between formulations is straightforward — which matters if you run several lotion variants on one machine.

RX becomes the better answer when the range extends into thicker products: body butters, high-solid after-sun, or anything with meaningful powder loading. Its bottom-entry homogenizer and external circulation loop keep heavy batches moving, and because it discharges through the homogenizer it also handles products that would otherwise need pumping out. RB is the alternative when ceiling height is the problem.

Whichever layout you choose, all three are built with SS316L contact parts polished to Ra ≤ 0.4 µm, and all three run the same water-ring vacuum at −0.09 MPa — so the process you develop transfers between them.

FAQ about Body Lotions & After-Sun

Can I make body butter on the same machine as body lotion?

Usually yes, but the machine has to be the right one. Body butter sits far higher in viscosity than a lotion and loads more powder, which is where RX's external circulation loop earns its keep. On an RS, a very heavy batch may not circulate well around the top-entry head.

How long does a lotion batch take?

Roughly two to four hours end to end for a typical formulation: heating the phases, combining and homogenising under vacuum, cooling under agitation, dosing fragrance and actives, then discharging. The cooling stage is usually the longest single step.

Do I need heating and cooling on the vessel?

Yes, for any commercial lotion. Most formulations require the phases to be combined hot and then cooled in a controlled way to set the texture. Separate heating and cooling tanks would mean an extra transfer and an extra cleaning cycle.

What is the smallest lotion machine you build?

Lab sizes exist in the same RS and RX families, which is what we recommend for formulation trials before committing to a production vessel. Developing on the lab machine in the same family makes the scale-up far more predictable than developing on a benchtop stirrer.
