Wet to dry ratio for bath bombs.

[icg]

I decided to make my bath bombs on Friday, as the following weeks have really low humidity. I'm just worried about the wet to dry ingredient ratio. Since I don't have any clay with me, I don't know if it will be too soft. My oils are poly 80, avocado oil, coconut oil (refined), sweet almond, maybe alcohol, and fragrance/essential oil. I first need a wet to dry ingredient ratio. I have how much dry ingredients I need, but I don't want it too be too wet. Does 1:10 seem good? Once I got that, should at least half of the wet ingredients be poly 80 or maybe 25%. If what I just said confuses me, feel free to ask for clarification. Just asking so I don't waste too much ingredients trying experiments.

I'll post the result pictures once I make them.

Hmm. A bit confused. Your polysorbate seems high. What dry ingredients are you going to use? Keep it simple. I only use 2 types of carrier oils, plus fragrance and a very small amount of polysorbate. How many ounces of dry ingredients? Amount?

I would use ie cups (I do use weight )
2 c Baking soda
1 CA
4 tbsp of oil + as much Poly 80 as essential oils
few sprays of RA 70%

Dry ingredients are the usual - epsom salts, baking soda, corn starch, citric acid. You can consider mica as dry, but it should be mixed with wet... right? I'm thinking a 10:1 dry to wet ratio, with maybe 25% of the wet being polysorbate 80? Or is that too much...

For bath bombs I mix mica with the dry. That way you can easily distribute the color without worrying about setting off the fizzing

What exactly does rubbing alcohol do to help bath bombs and by your recipe, about a 20:1 dry to wet ratio?

I would adjust it as it go and RA is a binding agent , the oil plus minus, when you mold bb the ingredients must be mixed well and damp like a damp sand, you should see some of the youtube videos
