Posted on: March 6 2013A sulphur suspension with Carbowax 1500.
The following sulphur suspension is Carbowax 1500. Carbowax 1500 no longer exists, but a mixture PEG 1500 + PEG 300 (1 + 1).
R/Colloidal sulfur 20ghave in Book of you read that PEG is incompatible with Sulpho resorcinol? When dissolving PEG in water, I get no ointment. How do I start, and what should I expect. An ointment (PEG) or a viscous liquid?
camphor alcohol 30
Sulpho resorcinol 9
Lactic acid 3
ZnO 15
Carbowax 1500 30
Propylene glycol 30
Aqua AD 300cc
Answer
You cannot obtain an ointment with this amount of PEG. The Carbowax is supposedly added to increase the viscosity, possibly to keep the camphor, which precipites when diluting the camphor alcohol with water, in solution. Thirty grams of Carbowax 1500 you can prepare with the mixture of 18g PEG 400 together with 12g PEG 4000. The incompatibility of Sulpho resorcinol is concentration bound; She usually leads to a curse; What is not so annoying here.
It is probable that a viscosities enhancement substance should be added. For sulphur suspensions, one usually uses bentonite or cattle gum in a concentration of 2%. As well as 1.5 g Tween 80 Add to moisten the sulfur.
In A tarred mortar with pestle, bentonite is mixed with resorcine, ZnO and sulfur. Dissolved In water of 60 ° C PEG 400, PEG 1500, lactic acid and Tween 80. The powder mixture is moistened with this warm solution and blended into a homogeneous suspension. After cooling, propylene glycol and camphor alcohol are added to this suspension.
