What is the Role of borax in cold cream
Answers
Answer:
Beeswax-borax-petrolatum cold creams
When borax is dissolved in water it produces boric acid and sodium hydroxide. The sodium hydroxide interacts with cerotic acid in the beeswax – a free fatty acid that makes up about 13% of beeswax by weight – and forms an anionic emulsifier, while the boric acid buffers the system.

Answer:
Cold creams are generally beeswax-borax mixes. They're called cold creams because during an operation to the skin the evaporation of water leads to the cooling effect.
When a result of borax is added to molten beeswax, the emulsifying agent is formed because of wax acid & borax i.e. wax acid is saponified by borax forming Na- cleaner( i.e. Na cleaner of wax acid). This agent is formed at the interface between oil paint & water, which emulsifies the mineral oil painting in water.
It's because of beeswax, cream is suitable to contain a perceptible quantum of water.
These are generally white creams of advanced-class free form greasiness, which has firm thickness & on the operation they run and spread fluently.
This cream can be either o/ w type( or) w/ o type depending upon the rate of the water phase. 45per cent is considered to be the critical position of the water phase, cream- containing water lower than 45percent is w/ o type & cream with a water phase further than 45percent is o/ w type of conflation.
