Is using an HDPE 2 bucket okay to use as mixing bucket?

[MatthewDM]

I have a Rubbermaid brand plastic (HDPE 2) bucket. Is this safe to use as a mixing bucket? Will it have any negative effects on the soap?

It needs to have a 1 or a 5 in the little triangle. 2 and 3 will melt(personally verified).

I believe HDPE is recycle code 2. 5 is PP.

AFAIK, yes HDPE is both heat and chemical resistant so should be fine, I use it all the time. In my experience HDPE holds up better than PP (5), but either 2 or 5 should be fine.

eta: HDPE is what laundry detergent bottles are made of, and a lot of soapers use those for long term storage of 50% lye solution.

I have used the same hdpe #2 for several yrs in the micro for melting oils. They will melt if you overheat your oil and only have a small amount in the bucket. Otherwise they work fine
