Rose concrete holds two valuable things. One is the fragrance that becomes rose absolute. The other is rose wax. To make absolute, you must separate the two, and this stainless steel filter does that job.
How the filter separates rose wax
First, the rose concrete dissolves in alcohol. Then the solution cools down. At low temperature, the rose wax turns solid, while the aroma compounds stay in the liquid.
Next, the operator pours the cold solution onto the filter. The fine spiral plate holds back the solid wax. Meanwhile, the clear solution passes through and moves on to the evaporator.
Design details
- Spiral perforated plate: a large filter surface with fine, even holes.
- Hinged lid: easy access for loading and cleaning.
- Outlet valves: controlled draining of the filtered solution.
- Stainless steel body: clean and resistant to alcohol.

What happens to the rose wax?
Rose wax is not waste. In fact, it is a natural wax with a light rose scent. Makers use it in solid perfumes, balms, lip care and natural cosmetics. So many producers sell it as a separate product.
Like other natural waxes, it melts with gentle heat and blends well with oils. Therefore, it suits both small brands and large cosmetic firms.
Tips for a clean result
- Cool the solution fully before you filter it.
- Keep the filter cold during the run.
- Wash the collected wax with cold alcohol to recover more absolute.

In short, a good filter gives you two products from one concrete: a clean rose absolute and a fine rose wax. Both have strong markets, so careful filtering pays off twice.
FAQ
Why cool the solution before filtering? Because wax turns solid at low temperature. As a result, the filter can hold it back.
Is rose wax a by-product or a product? Both. It comes from absolute production, but it also has its own market in cosmetics.
