Careful mixing.
Safe manufacturing.

ISO-certified specialists.

30+ Years of Manufacturing Expertise, Backed by Independent Audits

Formulations

Aqueous & alcoholic liquids.

Water-based

Formulations in which water is the main base ingredient. The water grade used is matched to the product category. Our in-house water treatment plant produces both Aqua Destillata (demineralised water) and Aqua Purificata (purified water).

Aqua destillata
Distilled or demineralised water, used in perfume and fragrance manufacturing.

Aqua Purificata
Purified water, used for liquid medical devices for topical application.

Alcohol-based

Formulations with ethanol as a primary component. Demand specific handling protocols, safety procedures, and filling environments suited to flammable substances.

  • Sprays

  • Perfumes

  • Aftershaves

  • Tinctures

Infrastructure

In-house water treatment.

Quality in aqueous formulations starts with the water itself. Our in-house water treatment plant produces on site: Aqua Destillata for fragrance manufacturing and Aqua Purificata for medical applications, eliminating the uncertainty that external sourcing would introduce.
