How to make LIQUID soap from biodiesel glycerine? Recipe appreciated! : )

post #1 of 3
Thread Starter 

Could anyone please tell me how to make LIQUID glycerine soap from biodisesel glycerine?

 

All the recipes I am seeing are for bars. I'd really like some help with a liquid recipe.

 

I'm going to pick up many gallons tomorrow. It comes in 5 gallon buckets, and I'd like to make it into liquid soap and store it right back in the bucket. It will be used for laundry, shampoo, dish soap, hand soap, etc.

 

What I'm going to pick up is already strained and demethane'd. So does that take out the heating to 175* step?

 

I am finding some pretty cut and dried (ha ha) directions all over for the bars, so I think that will be fairly straightforward. But not seeing any info on how to make a liquid soap?

 

Also, how long would the glycerine keep, as-is, in the bucket until I make soap?

How long would liquid soap keep in a bucket?

 

Any of your recipes or directions for liquid vegetable glycerine soap from biodiesel glycerine would be very appreciated!

 

Thanks!

I've only made hard soap, but I have two links for you that look plausible and no hype.  You might already have them.  One is just natural and you could apply it to biodiesel, the other is specifically for using with biodiesal.

Thanks very much!  : ) Some good info here. I can see I have a lot to learn.

 

I picked up 35 gallons of de-meth'ed biodiesel glycerine last night. It is dark brown like molasses. I wondered if I would have to bleach it because the glycerine soaps I have seen in stores are clear and jewel colors. I understand that bleaches are available but not necessary, the color does not affect the soap. Natural animal fat softsoap used in pioneer days was also brown, as are a variety of soaps. From what I am seeing, the brown color is kind of the "signature" of natural, vegetable biodiesel glycerine soap.  : )  My first batch I am not adding any scents, etc I want to see it for what it is and get a sense of how it behaves in use, and in the soapmaking process.

 

I picked up a can of lye for $7. Same place also has potassium hydroxide for $13. I will make bars first and then go get some of the potassium hydroxide to make some liquid. I understand that if I want to use it for laundry, etc a bar will work fine as long as it is sudsed/dissolved in the water first. Also, people use the bars for shampoo, same thing, it does not strictly have to be a liquid, from what I understand, to use for these purposes. Dry bars are lighter and easier to store, I would assume, and can't tip and spill, a plus.

 

I'll update again how it went!  : )  Thanks  : )
