Benzotriazole phenols with substituents either ortho to the phenol hydroxyl group and/or para to the phenol hydroxyl group can be prepared from the unsubstitued benzotriazole phenol by coupling reactions. The ortho substituent group can be a simple alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenol to another benzotriazole phenol group.

A class of antioxidant compositions include benzotriazole phenolate salts with substituents either ortho to the phenol hydroxide group and/or para to the phenol hydroxide group can be prepared from substituted benzotriazole phenols. The ortho substituent group can be a simple hydrocarbon, alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenolate to another benzotriazole phenolate group.
An object of the present invention is to provide skin external preparations and cosmetics which contain a branched acyl carnitine and have excellent formulation stability. A skin external preparation of the present invention includes a carnitine derivative represented by the following Formula (1) and/or a carnitine derivative salt represented by the following Formula (2), and an amphoteric surfactant.
In Formula (1), R
1
and R
2
are each independently a C1-18 optionally branched, saturated or unsaturated aliphatic hydrocarbon group. In Formula (2), R
1
and R
2
are the same as in Formula (1), X
−
is a specific anion and Y
+
is a specific cation.

This invention relates to novel UV absorbers, their methods of preparation, their use in stabilizing polymers and polymers so stabilized against the degradative effects of UV light. The novel compounds of formula I are oxamides which are substituted on one or both nitrogens with
a 2-hydroxy-3-(2H-benzotriazol-2-yl)benzyl group. The 2-hydroxy-3-(2H-benzotriazol-2-yl)benzyl groups are efficient UV absorbing groups and the oxamide group contributes additional light stabilizing, heat stabilizing and metal complexing properties to the compounds. The compounds have low-volatility and are especially useful as UV stabilizers for engineering resins processed at high temperatures.
