Study Notes
- Protectives are substances that are applied to the skin to protect it from irritation.
- Protectives are generally insoluble in water and have a chemically inert property.
- Protectives are usually applied as dusting powders, suspensions containing insoluble protective substances, or ointments.
- Protectives are usually applied to areas that are subject to constant irritation, such as the skin which is subject to moisture and/or friction.
- If the area to which the protective is to be applied is abraded and exuding fluid, adsorbent-type protectives should not be used.
- TALC USP XX (3MgO.4SiO2.H2O) is a protectives that is used to protect the skin.
- Talc is a white, odorless, tasteless, and insoluble powder that is used as a filtering aid and as a lubricant and dusting powder.
- When used on broken skin, talc can produce sterile abscesses or granulomas. This problem precludes the use of talc on surgical gloves.
- Absorbable dusting powders are now recommended for use on talc-containing medication. There are no problems with the use of talc on intact skin.
