smiley_miley Posted July 23, 2005 Share Posted July 23, 2005 I am going to make lotion, and the preservative I will be using is Liquapar Optima. It says I should use about 0.5% in lotions. So, if I make say a 16 oz batch of lotion, how many drops do I put in? I can figure out what weight it should be, but I can't measure weight that small, lol Quote Link to comment Share on other sites More sharing options...
Rebecca Posted July 23, 2005 Share Posted July 23, 2005 Well if I did the math right .5% of 16oz is .08 of an ounce. From what I was able to find there are about 360 drops per ounce so you would just have to break it back from there. Taking it down to 1/2 an ounce which equals 3 teaspoon which equals 180 drops...and so onHere a link I found to a chart it doesn't go as far down as you need but it's a neat chart.http://treetotem.com/hpmeasure.htmHope that helped a little.

RobinInOR Posted July 23, 2005 Share Posted July 23, 2005 You really need to make bigger batches or get a scale that can measure correctly. Too much preservative can be irritating to the skin - too little preservative won't preserve. Why take the chance? Quote Link to comment Share on other sites More sharing options...
