What Does Solvent Cleaning Mean? Solvent cleaning is a cleansing process that uses chemical solutions to remove unwanted grease, oil, residue, coatings or paint from the surface of a material.
Does rubbing alcohol damage photos?
Alcohol with a lower purity, such as rubbing alcohol, will cause streaking and take longer to dry. Also, the higher water content of rubbing alcohol may cause the emulsion of the photographic materials to swell, resulting in physical damage and possible deterioration of image-forming dyes.
Can you use alcohol to clean photos?
Wrap a cloth around your finger and moisten with a small amount of alcohol. Gently wipe the negatives with the alcohol to remove remaining build-up. Start with the least important picture to make sure no damage occurs. This should effectively remove grease and mildew without damage.
What are 3 emulsifiers examples?

Which surfactant is mostly used as an emulsifying agent?
The surfactant is then referred to as the primary emulsifying agent and the stabilizer as the secondary or auxiliary emulsifier (5). An example of such a system is the use of the primary emulsifier sodium lauryl sulfate with the auxiliary emulsifier stearyl alcohol in Hydrophilic Ointment USP (6).

What are the two types of emulsifiers?
Two types of emulsifiers are used: (1) mono- and diglycerides and (2) polyoxethylene derivatives of sugar alcohol fatty acid esters.
What is difference of surfactant and emulsifier?
Surfactants are amphiphilic, meaning that they contain hydrophilic (water-loving) head groups and hydrophobic (water-hating, or oil-loving) tails. Surfactants adsorb at the interface between oil and water, thereby decreasing the surface tension. An emulsifier is a surfactant that stabilizes emulsions.
