One male patient who had positive patch test from butylated hydroxyanisole
(antioxidant in cosmetics), triethanolamine (surface-active agent in soaps, shampoos), and gallate mix was using fairness creams, antiacne (herbal) cream, and soaps but elicited no positive reaction from these products.
In the DPPH radical-scavenging assay, Table 2 shows the concentrations of butylated hydroxyanisole
(BHA) and the Thai herb extracts, at which the DPPH radicals were scavenged by 50 % ([IC.sub.50]), the lower the [IC.sub.50], the higher the antioxidant activity.
Ascorbic acid, Butylated hydroxyanisole
(BHA) and [alpha]-Tocopherol for antioxidant activity.
(BHA), butylated hydroxytoluene (BHT) and Ascorbic acid were used as reference materials.
Common antioxidant preservatives include butylated hydroxyl toluene (BHT), butylated hydroxyanisole
(BHA), tertiary butyl hydroquinone (TBHQ) and propyl gallate (PG).
( BHA is used in cosmetic products as a preservative but is considered to be a possible carcinogen by the World Health Organisation.
Another change (amongst others) would introduce maximum levels for butylated hydroxyanisole
(BHA) in lard, beef, poultry and sheep fat.
EGCG also topped other antioxidants, such as butylated hydroxyanisole
(BHA), butylated hydroxytoluene (BHT) and resveratol.
