VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 23, 2008) - ALDA Pharmaceuticals Corp. (TSX VENTURE:APH) ("ALDA" or the "Company") has received Drug Identification Number ("DIN") 02314320 from Health Canada that approves the marketing of T36(R) Antiseptic Hand Sanitizer ("T36(R) AHS") in Canada. ALDA's T36(R) AHS contains 0.15% benzalkonium chloride ("BZK") in 70% ethanol. This combination of ethanol and BZK is more powerful than standard alcohol hand sanitizers, which typically contain only 62% ethanol and do not kill all types of infectious micro-organisms.

Dr. Terrance Owen, President and CEO, states, "This is an important milestone for the company because this new DIN marks the first time that the T36(R) technology has been approved for human use. We will be introducing this product to the retail and institutional markets under the new name "T36 Disinfex(TM)". We have seen some very attractive packaging options and want to differentiate our product from the competition in both appearance and, more importantly, performance."
