Cellugel

Cellugel was developed for books effected by red rot (powdery deterioration).
This effective and successful consolident for deteriorating powdery leather was developed by professional book conservators. Cellugel is essentially a mixture of hydroxypropylcellulose and isopropanol. Cellulose ethers have been used by book and paper conservators for years for the purpose of sizing paper and consolidating deteriorated leather. When applied to powdery leather (leather with red-rot), Cellugel is absorbed throughout the entire thickness of the leather and dries within minutes. After it is dry, the dust no longer comes off the leather. Cellugel does not darken, discolour nor leave a film on the surface of the leather.
