Chemical and physical data

Liquid paraffin, also known as paraffinum liquidum, is a very highly refined mineral oil used in cosmetics and for medical purposes. This is a UK definition (British Pharmacopoeia) and the term may have different uses in other countries. The cosmetic or medicinal liquid paraffin should not be confused with the paraffin (or kerosene) used as a fuel.

The term paraffinum perliquidum is sometimes used to denote light liquid paraffin. Conversely, the term paraffinum subliquidum is sometimes used to denote a thicker mineral oil.

Usage and side effects orally as laxative[edit]

Liquid paraffin is considered to have a limited usefulness as an occasional laxative, but is unsuitable for regular use as it can seep from the anus and cause irritation.[citation needed]

Efficacy of liquid paraffin is suggested by 2016 Cochrane review.[1]

It might interfere with the absorption of fat-soluble vitamins, though evidences seem low.[2]

It can be absorbed into the intestinal wall[citation needed], and may cause foreign-body granulomatous reactions in some rat species but not in others and that reaction might not occur with human.[3]

There are evidences suggesting the lack of carcinogenicity.[4]

If it enters the lungs, it can cause lipoid pneumonia.[5]

Liquid paraffin is also used in combination with magnesium as an osmotic laxative, sold under the trade name Mil-Par (among others).[6]

Side effects if injected[edit]

Causes granulomatous reactions if injected.[7]
