Toothpaste increases the effect of mechanical tooth cleaning. It is a soft paste or a gel and often contains fluorides against caries and periodontitis. We plan and supply vacuum homogenising mixers for batch production. Find out more in our cosmetics section.

The main components of dental cream are:
Batch production step by step
Toothpaste is made in batches or continuously. In the batch process, a plant with a scraper agitator, homogeniser and vacuum system usually works like this:
- 1ChargingFirst, the humectants glycerine and sorbitol go into the mixer.
- 2Drawing in bindersNext, the plant draws in binders such as sodium carboxymethyl cellulose in stages below the liquid level, while agitating and homogenising in circulation.
- 3Completing the solutionThen deionised water, saccharin, preservatives and other additives follow one after another.
- 4SwellingFurther agitation and homogenisation support the swelling of the binders.
- 5Drawing in solidsAfter that, abrasives such as chalk, fumed silica and finally the surfactant are added in portions under vacuum. As a result, foam does not disrupt the process.
- 6DeaerationUnder vacuum, the compound is deaerated until it is smooth and supple.
- 7Flavour and releaseFinally, the plant draws in the flavour oils. After laboratory release, the mixer is emptied.
Important: the flavours must not evaporate during deaeration.
What matters in the design
- A powerful scraper agitator with very good vertical mixing and reversible direction of rotation
- A powerful homogeniser with good pumping capacity, even under vacuum
- A rotor-stator system with wear protection
- Carefully designed feeds for powders and flavours
- GMP-compliant design without corners, edges or dead zones
- GMP-compliant CIP cleaning, for example with rotating jet cleaners

FAQ: Producing toothpaste
What is toothpaste made of?
Abrasives (e.g. silica, chalk), humectants (glycerol, sorbitol), binders (e.g. carboxymethyl cellulose), surfactant (usually sodium lauryl sulfate), flavours, sweetener, preservatives and actives such as fluorides.
How is toothpaste produced in batch?
Charge humectants, draw in binder under vacuum and let it swell, add water and additives, draw in abrasives and silica in portions, finally add surfactant and flavour, deaerate and discharge after lab release.
Why is the surfactant added last?
So that foaming does not disturb the previous process steps and the mass can be deaerated well.
Which machine is suitable for toothpaste?
Vacuum homogenising mixers with a powerful scraper agitator, a homogeniser with good conveying capacity and wear protection, powder induction below the liquid level and GMP-compliant CIP cleaning.
Does SEEFRIED supply toothpaste plants?
Yes, we plan batch and continuous toothpaste plants and offer inspected used homogenising mixers.
