K-Y

was trying to revise for tmr's dispensing test when an unanswered question from long time ago suddenly creeped into my mind..

***

in army, they keep tubes of this substance called K-Y jelly (draws sniggers from the guys).
primary use: lubricant for medical purposes.

according to the website, it has several ingredients:

Chlorhexidine Gluconate
Glucono-(delta)-Lactone
Glycerin
Hydroxyethyl Cellulose
Methylparaben
Purified Water
Sodium Hydroxide.

hmm.. was wondering, how does this thing work? using current year 2 pharm dfd knowledge.

given the presence of all these ingredients in the lab, can we try to make it?? hehe. *more sniggers*
