Yes, that's right 👍👍

Generally the shampoo base you buy already has preservatives. Sles based shampoo has parabens as preservatives and sulphate free has potassium sorbate etc., For natural shampoo, a preservative is not necessarily needed as it is a self sustaining emulsion like CP Soap

The most widely used and beat suited fragrance option for charcoal is the musk fragrance. You can also try the vertiver fragrance for it

For gels and lotions, hydrosols or distillates are added as a substitute to water and it is made by heating and condensing the water of plant material. It is available with supplier society also The preservatives for gels suggested is phenoxy ethanol and phenonip for creams and lotions

Hello, The dosage used is 1% meaning 10g per 1000g of cream. It is widely used for preserving creams, lotions and gels. As for shampoos, this does work but potassium sorbate is generally used for paraben free preservation in shampoo

Hello, The issue will most probably be with the lye calculation or the trace may not have reached. Pls share the lye calculation and water added also

Hello, I have tried adding glucosides such as Lauryl Glucoside or APG which I find increases the lather in melt and pour soap and it is sulphate free also. Just an additional 3-5% has made a notable difference

Generally, I find that after the paste is made with KOH, twice the amount of water can be added for a fairly thick liquid soap

The soaps seems to be good. However, you can try out the carrot powder available instead of the puree as it will help your soap hold any fragrance if added to be retained for a longer period of time

The calculations are correct and the soaps have turned out well. You can cure it in the open such that it has good airflow and soaps do not need any preservatives. You just have to allow it to cure and you can pack them

Sweating is formed as a result of glycerin in the soaps which attracts moisture from the air. To avoid this you can simply wrap the soap with a plastic wrap preferably shrink wrap since the sweating is formed not from inside but by attracting moisture from the outside. If the sweating is less, you can just dry it with a fan or blower. The sweating is not something you need to worry about and is natural for a glycerin base to sweat

Your calculation seems to be right. As for curing it is recommended to keep in a place with good airflow.
