Nasal sebum , also known as nose fat/oil , is the fat removed from the surface of the human nose. The lateral pleated pores (where the nose joins the face) from the outside of the nose make and store more oil and fat than the pores elsewhere in the human body, forming a small amount of available fats or oils. Fat is a very oily form of sebum, thought to contain more squalene (C 30 50 ) than secretions from other parts of the skin. This is important because nose oil is a durable lubricant.
Nose grease can be used to minimize scratches on the optical surface, for example when cleaning negative photos. Observational knowledge suggests that nose oil is used to reduce light and reflections of light in a transmissive telescope before the development of a vacuum antireflective coating. The antireflective properties are partly due to the fact that the nasal oil fills tiny cracks and scratches and forms a smooth, polished surface, and partly on a low index of refraction of oil, which can reduce the surface reflections of transmisive optics having a high refractive index. The same effect is sometimes used by numismatic hobby enthusiasts to change the apparent value of a slightly worn coin.
Nose oil is often recommended as a fly fishing ferrules lubricant.
Nose oil has mild antifoaming properties and can be used to break the head high on a beer or soft drink freshly poured. Wiping the nose oil onto one's finger and then touching or stirring the foam causes it to disappear quickly.
The Doctor's Book of Home Remedies suggests using nasal sebum as a medicine for chapped lips.
