Abstract
A novel class of acid addition salts of aminomethyl-o-hydroxyphenones having ultraviolet absorbing properties in the 300-350 mu range having the following formula: ##SPC1## Wherein R represents hydrogen or an alkyl radical of from 1 to 4 carbon atoms, R.sub.1 and R.sub.2 each represents an alkyl radical of from 1 to 4 carbon atoms, n has a value of 1 to 3 and X is an acid moiety selected from the group of hydrochloric, hydrobromic, sulfuric, phosphoric, acetic, formic, propionic, p-toluene sulfonic, behenic, benzene sulfonic, tartaric, citric and benzoic acids. These salts have been found to be skin substantive and particularly adapted for use as sun-screening and/or sun-tanning agents.
Claims9
A sun tanning and hair protecting composition comprising between about 0.4% and about 10% by weight of a compound selected from the group consisting of acid addition salts of a compound having the formula:
- ##SPC11##
- wherein R is hydrogen or an alkyl having from 1-4 carbon atoms, R.sub.1 and R.sub.2 each represents an alkyl having from 1-4 carbon atoms and n has a value of 1 to 3, said compound having ultra-violet absorption in the sun burning range of 300-350 m.mu. while transmitting radiation in the sun tanning range;
- and a carrier selected from the group consisting of water, vegetable oil, mineral oil, and aqueous solutions of methanol, ethanol, glycerol and isopropanol.
