In light of the recent success of some of our powdered detergents, we have decided to renew our range.
What are the key advantages of powdered detergents?
- Powder detergents have a longer shelf life than their liquid counterparts—at least 24 months—with no phase separation.
- The absence of water drastically reduces environmental impact during transport. A powder is 100% active material, meaning lower dosage is needed to achieve the same performance as a liquid detergent.
- Our range of powders offers enhanced versatility, both in terms of material compatibility and the types of contaminants it can remove.
- Our powders are free from CMR and SVHC substances.
For ophthalmic optics and precision applications.
Optical 2010 P
Surface preparation and finishing for ophthalmic optics prior to hard coating. It can also be used for cleaning after surfacing. Optical 2010 P is the most alkaline product in the NGL range and is therefore particularly effective for lens etching prior to hard-coating—helping to improve the efficiency and yield of your hard-coating lines.
It can also be used for varnish removal or cleaning after surfacing by simply adjusting the dosage.
Optical 10 P
Used as a finishing step after Optical 2010 P, Optical 10 P, with its excellent rinsability, completes the surface preparation process.

Surface activation of organic lenses prior to hard coating.
For luxury industries (watchmaking, jewellery, accessories) and high-precision applications.
Galvaprep 17.41 P
With a pH of 13.3 and an ultra-degreasing formulation, Galvaprep 17.41 P is an excellent detergent for removing stubborn contaminants such as polishing compounds, greases, and tallow. When used with Solvit No. 4 as an acidic finishing step, this combination is particularly valued for its performance in surface preparation of nickel-plated faucets prior to PVD coating.
Galvaprep 18.40 P
Slightly alkaline, Galvaprep 18.40 P is an excellent degreasing agent with a broad material compatibility range, from copper alloys to precious metals. This product is particularly valued by research laboratories for cleaning ultra-high-purity copper components (ASTM C10100, ≥99.99% Cu, ≤5 ppm O).
Galvaprep 2018 P
Less alkaline than Galvaprep 17.41 P, Galvaprep 2018 P offers strong degreasing performance along with broad material compatibility, particularly aluminium.
Process example
Removal of polishing compounds using ultrasonic cleaning.
Galvaprep 17.40 P
Soft cleaning, hydrophilic finishing
For soft cleaning applications and optimal finishing, Galvaprep 17.40 P perfectly completes the three references above, providing spot-free rinsing, ideal prior to particle counting.
Questions to consider when choosing a powder detergent over a liquid detergent.
What is the shelf life of a powdered detergent?
By definition, a powder is a dry product; therefore, phase separation (separation of liquid components) is not possible. Provided the product is stored away from humidity, the shelf life of a powder is at least 24 months, facilitating inventory management.
What precision cleaning objectives are met by powdered detergents?
The same as liquid detergents. The main advantage lies in the fact that formulation stability issues are eliminated, which broadens the choice of components and therefore increases the compatibility range of a single product.
Where 3 or 4 different liquid references may be required to remove various contaminants from different materials, a single powder can address the full scope of cleaning challenges.
In what way is a powdered detergent more sustainable?
Being a dry product, powder eliminates the need to transport water, which can represent more than 50% of the composition of liquid formulations. As a result, using a powder significantly reduces the carbon footprint associated with transportation.
In addition, because powders are more concentrated, less product is required to achieve an equivalent concentration of active ingredients in a cleaning tank.
Are there any disadvantages to using powdered detergents?
Yes. A powder can be dusty, so appropriate PPE should be used, and abrupt handling should be avoided. The work area should also be carefully cleaned after manipulation.
For controlled environments, it is preferable to prepare a pre-diluted solution before entering a cleanroom or grey room.
Attention must also be paid to dissolution: if necessary, the powder should be added gradually to prevent clumping. Mixing in preheated water is recommended, and sieving can also help the dispersion.
