This is a repost from last year for those interested: KY jelly ingredients
Propylene Glycol, Polyethylene Glycol, Hydroxypropyl Cellulose, Lactic Acid The effectiveness can be GREATLY increased by adding some DMSO to the gel. I would recommend as the first try using Polyethylene Glycol, DMSO and CS. The gel version of DMSO from Neogen Corporation uses Polyethylene Glycol as it's thickening agent, so it should all be very compatible. Organic thickeners are: Xanthan gum carrageenan agar agar gelatin guar gum cellulose gum In regards to Pharmaceutical agents for making Topical Gels-- Methylcellulose Hydroxypropyl Cellulose Lipoil Poloxamer NF Pluronic F127 Polyethylene Glycol In all cases if organic thickeners are used a preservative MUST be used to prevent fungus growth. CS in a gel has too low a mobility to prevent mold growth. This should not be necessary if using pharmaceutical agents as no nutrients should be available.. The following is a recipe that some on the CS list are using, I don't remember who originally posted it: 90 ml CS 2 ml Xanthum Gum 10 ml Aloe Vera concentrate (I use 1:10) a few drops of a preservative, such as grapefruit seed extract. sodium bicarb Gently heat the CS till it's lukewarm (this will make the gum melt more easily) sprinkle the gum and beat vigorously. If you don't want to introduce air bubbles into your mixture, keep the whisk on the bottom of the pan. Add the AV concentrate and preservative. (I've found that after about three weeks the gel develops a mold of some description. This is about two weeks longer than using just water, so the CS is doing something, just not for very long.) Bring the mixture back to around 7 ph with sodium bicarb using litmus paper. You can use other thickening agents such as cellulose gum, roughly twice as much should do it.
