Hindered phenol

== Description ==
A class of antioxidant added to varnishes and polymers to minimize thermal oxidative degradation. Hindered phenols are phenols with one or more bulky functional groups such as a tertiary butyl (Mills and White 1994). They are free radical scavengers that combine with peroxy and alkoxy radicals to break any autocatalytic cycle. Hindered phenols are not very effective for photochemical oxidation and may produce colored byproducts. One common hindered phenol is butylated hydroxytoluene (BHT).

Hippopotamus teeth

== Description ==
Large upper and lower canine teeth from the hippopotamus (Hippopotamus amphibius). The upper teeth can grow to 20 cm while the lower tusk can grown to 70 cm. Hippopotamus teeth have been used as ivory after the thick, hard enamel layer is removed. Of the materials that have been used as ivory substitutes, hippo teeth are the hardest and most opaque (Thornton 1981). They are close-grain, polish to a high gloss and rarely yellow with age. Microscopically, the hippo teeth may exhibit an irregular wavy pattern but they do not exhibit the layered ring structure and peeling that are found in elephant ivory. See also ivory.
== Synonyms and Related Terms ==
ivory substitute; hippopotamus ivory; Hippopotamus amphibius;
== Physical and Chemical Properties ==
UV autofluorescence is bluish white with some purple.
Density	1.80-1.95 g/ml
