Vacuum emulsifying mixers for face creams: day cream, night cream, anti-aging, BB/CC creams. SS316L, 5 micron particle size, mirror-polished. From 5L lab to 2000L production.

Key Takeaways

Cream quality is decided by droplet size, not by how long you stir. Homogenising under vacuum is what turns two phases into a stable emulsion instead of a temporary mixture.
Vacuum is not a luxury on creams: it removes the air beaten in during homogenising, so you avoid surface pinholes, oxidation of the oil phase and a shorter shelf life.
Heat, emulsify and cool in one vessel. Jacketed heating takes the phases to working temperature, jacketed cooling brings the batch back down — no transfer, no second cleaning.
Actives and fragrance go in last, below roughly 40 °C. Adding them hot is the most common way to lose the ingredient you paid for.
Size the vessel on batch size and shift pattern, not on ambition. A 300 L machine running two batches a day usually beats a 1,000 L machine running one.

What you're making

Day creams, night creams, anti-aging creams, BB/CC creams, foundation — these are oil-in-water (O/W) or water-in-oil (W/O) emulsions where droplet size, uniformity and air content determine the final feel on skin.

Typical capacity: 1L (lab) — 2000L (production)
Typical viscosity: 5,000 – 50,000 cps typical

PROCESS

How to make it on our machines

Heat oil and water phases separately → combine under high-shear homogenization at 70–80°C → cool under vacuum while continuing agitation → add actives and fragrance at low temperature → discharge.

What actually goes wrong in cream production

Three failures account for most of the cream batches that get re-worked. The first is graininess: the waxes and butters in the oil phase crystallise at different temperatures, and if the cooling rate is not controlled the batch comes out sandy instead of smooth. A jacketed vessel with a scraped-wall agitator gives you a defined cooling curve instead of letting the batch sit and cool however it cools.

The second is air. High-shear homogenising is violent by design, and everything it does to the droplets it also does to the headspace — air gets folded in and stays there. Under vacuum at −0.09 MPa that air is pulled out as the batch is homogenised, which is why vacuum and homogenising belong on the same machine rather than in two separate steps.

The third is over-shearing. More homogenising time does keep reducing droplet size, but past a point the extra time costs you cycle time and can thin a structured cream below its target viscosity. The practical answer is to set homogenising time by trial at lab scale and then hold it constant in production.

RS or RX for face creams

RS is the general-purpose answer and the one most cream makers should start with. Its homogenizer enters from the top and emulsifies inside the vessel, and the vessel tilts to discharge — which makes both emptying and cleaning straightforward. It suits medium-viscosity products with light powder loading, which is exactly the profile of a day cream, night cream or BB cream.

RX earns its place when the formulation gets heavier. Its homogenizer enters from the bottom and circulates the product through an external loop, so it keeps moving high-viscosity and high-solid batches that would otherwise stall around a top-entry head. It also discharges through the homogenizer itself, which suits water-in-oil creams and formulations with more powder in them.

If headroom is the constraint rather than viscosity, RB is the third layout: the emulsifying pump stands beside the tank as a separate unit instead of above or below it. It is also the easiest of the three to service.

From lab batch to production batch

Scale-up is where most cream launches lose time. A formulation that works beautifully at 5 L can come out of a 500 L vessel with a different texture, because the power input per litre and the cooling rate are both different. Running the first trials on a lab machine from the same family — RS or RX in lab size — keeps the geometry of the homogenizer consistent and makes the jump far more predictable.

What transfers is the process, not the rpm. Hold tip speed and homogenising time constant between scales rather than copying the speed setting, and expect the cooling stage to take longer on a bigger vessel because the surface-to-volume ratio works against you.

FAQ about Face Creams & Moisturizers

Can one machine make both oil-in-water and water-in-oil creams?

Yes. The vessel does not care which phase is continuous — what changes is the order you add the phases and where you run the homogenizer. RS handles both comfortably at the viscosities typical of face creams; for heavier water-in-oil formulations with more powder loading, RX circulates the batch better.

Do I really need vacuum, or is a normal mixer enough?

For any cream you intend to sell, yes. Homogenising pulls air into the batch, and that air shows up as pinholes on the surface, a shorter shelf life and oxidation of the oil phase. Vacuum at −0.09 MPa removes it during the same step rather than as a separate de-aerating operation.

At what temperature do I add the actives?

Below about 40 °C, after homogenising and after most of the cooling. Vitamin C, retinol and most preservatives degrade if they go in hot. This is why the cooling stage happens in the same vessel — you dose the actives and then finish cooling under gentle agitation.

What vessel size should I buy?

Work backwards from your batch size and how many batches you want per shift, not from the largest machine in the budget. Remember that RS tops out at 2,000 L and RX at 5,000 L; a machine that is too large mixes a small batch badly because the homogenizer never gets properly covered.
