What are ultrasound gels made of?
Ultrasound gels are colourless and viscous gels that are water-based and contain a thickening agent. Because of the direct skin contact during an ultrasound examination, it is particularly important that ultrasound gels with the ingredients they contain are skin-friendly and do not contain any allergens. Furthermore, they should have the right consistency and high lubricity and conductivity and be as odourless as possible. High-quality ultrasound gels do not contain any ingredients such as formaldehyde, colourants, odorants, or UV stabilisers. Thanks to the water base, the ultrasound gel does not leave any stains on the patient's clothing and the ultrasound equipment can be cleaned easily. The patient's body can also be simply wiped with a cloth after the examination. If the ultrasound gel is to be used for examinations in the genital area, care should be taken to ensure that it has good mucosal compatibility, sterility, and adhesion.
