[Description]

4-Aminobenzoic acid (also known as para-aminobenzoic acid or PABA because the number 4 carbon in the benzene ring is also known as the para position) is an organic compound with the formula H2NC6H4CO2H. PABA is a white solid, although commercial samples can appear gray. It is slightly soluble in water. It consists of a benzene ring substituted with amino and a carboxyl groups. The compound occurs naturally. The potassium salt is used as a drug against fibrotic skin disorders, such as Peyronie's disease, under the trade name Potaba. PABA is also occasionally used in pill form by sufferers of irritable bowel syndrome to treat its associated gastrointestinal symptoms, and in nutritional epidemiological studies to assess the completeness of 24-hour urine collection for the determination of urinary sodium, potassium, or nitrogen levels.

[Uses]

octyl dimethyl PABA (padimate-O; p-aminobenzoic acid) is an FDA-approved sunscreen chemical whose InCI name is now ethylhexyl dimethyl PABA.
[Uses]

PABA is a sunscreen chemical with an approved usage level of 5 to 15 percent. It is found to be irritating to sensitive skin, has the potential to cause sensitization, and is considered too water soluble. once extremely popular, this ingredient has practically disappeared from sunscreen formulations. PABA is a yellowish or colorless acid found in vitamin B complex.
