Poloxamer 407 is a hydrophilic non-ionic surfactant of the more general class of copolymers known as poloxamers. Poloxamer 407 is a triblock copolymer consisting of two hydrophilic blocks (poly-ethylene glycol) separated by a hydrophobic block (poly-propylene glycol). The approximate lengths of the two PEG blocks is 101 repeat units while the approximate length of the propylene gycol block is 56 repeate units. This particular compound is also known by the BASF trade name Lutrol F-127.
Uses of poloxamer 407
Most of the common uses of poloxamer 407 are related to its surfactant properties. For example, it is widely used in cosmetics for dissolving oily ingredients in water. It can also be found in multi-purpose contact lens cleaning solutions, where its purpose there is to help remove lipid films from the lens. It can also be found in some mouthwashes.
Reports of adverse effects
It was reported in The Australian newspaper 18 November 2006 that this common ingredient in toothpaste and mouthwash can cause high cholesterol. A team from the Centre for Ageing and the ANZAC Research Institute in Sydney found that when P407 was given to mice, it coated cells in the liver that control cholesterol levels, leading to a 10-fold increase in levels. The amounts given were not reported in the article.
