‘Salicylic acid is oil-soluble so it’s able to penetrate deep into follicles and break down blockages within as well as the typical surface exfoliation,’ says A-list facialist and skincare specialist, Debbie Thomas. ‘This means it’s great for skin that’s prone to blockages and congestion.
Besides, Is salicylic acid soluble in oil?
The solubility of salicylic acid is, according to Moncorps,3 as follows: One part of salicylic acid dissolves in 13 parts of boiling water, in 444 parts of water at a temperature of 15 C., in 500 parts of water at 20 C., in 60 parts of glycerin, in 45 parts of olive oil and in 7 parts of castor oil.
Keeping this in mind, What do you mix with salicylic acid powder? You can make a slurry of propylene glycol and the salicylic acid powder in a bowl and then mix that with skin cream. The slurry is made by adding the solvent to the powder gradually and mixing it into a milky solution into which all powder is dissolved. This will likely be a 50% mix or thereabouts.
