使用
mineral oil is an emollient cleanser and demulsifier of dirt trapped in pores. Mineral oil is excellent for use in cleansers. In leave-on cosmetics, its comedogenicity or lack thereof appears related to the level of raw material refinement; therefore, some suppliers state that their product is non-comedogenic. When used in leave-on preparations, mineral oil’s occlusive capability is considered to help improve the epidermal barrier function. This is a clear, odorless oil derived from petroleum and is not known to cause allergic reactions.

適応症
Fecal softeners are substances that are not absorbed
from the alimentary canal and act by increasing the
bulk of the feces and softening the stool so that it is easier
to pass. Mineral oil has been in use for many years,
either as the oil or as a white emulsion; it is a mixture of
liquid hydrocarbons. Its use has been criticized for
many reasons. It dissolves the fat-soluble vitamins and
prevents their absorption.

副作用
It is itself absorbed slightly
and appears in the mesenteric lymph nodes, and if it is
inhaled into the lungs (which it may be in elderly or debilitated
patients), it may produce inflammatory responses
such as lipoid pneumonia. Its continual use,
therefore, is contraindicated, although its occasional administration
in otherwise well patients is not harmful. It
is employed primarily in patients who must avoid
straining at stool, including persons with hemorrhoids
and other painful anal lesions. Leakage of mineral oil
past the anal sphincter may lead to soiling of clothing.
