What is the optimal temperature for mixing oils with lye in the CP process? I mixed the oils and lye both at temperatures between 50-55 degrees Celsius (122-131 F) in several batches and the soaps came out well. Thank you in advance.
As Zing said, it depends. Higher temps will reduce the chance of soda ash, or false trace, but will also cause the soap to trace faster.
In the context of this sentence, did you mean that trace is accelerated with the heat, i.e., the batter becomes thick more rapidly than it tends to do at lower heat?I noticed that the saponification is accelerated at 50-55 C (122-131 F)
Good to know. No fancy swirls, no FO. IMO the main function of soap is washing. The emollient and moisturizing role applied to the skin (condition 56, creamy 19 and panthenol) somehow compensates for the high PH of the soap (10.2-10.5), which dries the skin and exposes it to microorganisms. Anyway, I'll set both the mixing temperature, the oils and the lye to 50C each (122F)....using a different temperature might be wise in the future if you want to do fancy swirls, if you want to use a FO or additive that can cause overheating, etc.
Panthenol (precursor of vitamin B5) is good for skin, hair and nails. It allows the skin to retain moisture and maintain hydration. The feeling of softness of the soap upon contact with the skin is very pleasant. After washing, the skin does not remain dry (tested). It also helps to heal wounds and burns. The soap is for personal use and I thought it would be good to improve its quality.I’m curious to learn why you use panthenol in your cold process recipe.
As others have said, there are no hard/fast rules. Basically it is going to be whatever you are comfortable with, and what works for your situation.
Soap by definition isn't moisturizing, despite how the calculator numbers are described. It can be less drying, or less stripping, but not moisturizing. If you were in the US, the use of the term "moisturizing" would set you up for problems with our regulators, unless you follow the labeling and other rules for using that term.The emollient and moisturizing role applied to the skin (condition 56, creamy 19 and penthanol) somehow compensates for the high PH of the soap
"penthanol"
@AliOop I wrote "penthanol" and I edited. Look at "NcDon said:" in your message. LOL
There really isn't one to be honest. When first starting out, 110F for both Oils/Butters and Lye Solution is often recommend as it ensures that the Oils/Butters are fully melted, lessens the chance for false trace and makes for a more successful soaping experience. Once you develop your own recipe (which every soap maker does, even if it's only a small tweak) and style, you will find the optimum temperature.What is the optimal temperature for mixing oils with lye in the CP process?
