please help me! My friend and I, for an Introduction to Chemistry class in college, need to present a subject and the chemistry behind it, so we selected personal lubricants, especially the chemistry behind " yours and mine" KY lubricant. I have been looking online for a day, and haven't come up with much technical information ....I need your help if anyone can point me in the right direction as to where I might find information I need. Thank you so much!
