para-anthranilic acid
benzoic acid, 4-amino-
 
Notes:
A member of the VITAMIN B COMPLEX. It used to be common in SUNSCREENING AGENTS until found to also be a sensitizer. The potassium salt is used therapeutically in fibrotic skin disorders. a member of the vitamin b complex. it used to be common in sunscreening agents until found to also be a sensitizer. the potassium salt is used therapeutically in fibrotic skin disorders. Listed in the EAFUS Food Additive Database (Jan. 2001) but with no reported use 4-Aminobenzoic acid (also known as para-aminobenzoic acid or PABA) is an organic compound with the molecular formula C7H7NO2. PABA is a white crystalline substance that is only slightly soluble in water. It consists of a benzene ring substituted with an amino group and a carboxyl group.; 4-Aminobenzoic acid, para-aminobenzoic acid, or simply PABA, is an organic compound with molecular formula C7H7NO2. PABA is a white crystalline substance that is only slightly soluble in water. It consists of a benzene ring substituted with an amino group and a carboxylic acid.; A member of the vitamin B complex. It used to be a common sunscreening agent until found to also be a sensitizer. The potassium salt is used therapeutically in fibrotic skin disorders.; PABA is an essential nutrient for some bacteria and is sometimes called Vitamin Bx. However, PABA is not essential for humans and it varies in its activity from other B vitamins. Although humans lack the ability to synthesize folate from PABA, it is sometimes marketed as an essential nutrient under the premise that it can stimulate intestinal bacteria.; PABA is an essential nutrient for some bacteria and is sometimes called Vitamin Bx. In humans, PABA is normally made by E. coli in the colon and therefore PABA from food is not normally essential to human health. PABA is therefore not officially classified as a vitamin. PABA is an intermediate in bacterial synthesis of folate. Although humans lack the ability to synthesize folate from PABA, that is also normally done by E. coli. PABA is sometimes marketed as an essential nutrient for use whenever normal PABA synthesis by intestinal bacteria is insufficient.
