I have recently started using used oils for making my soap. This is not only cheap for my family, it’s also good on the environment as many restaurants find it very expensive to dispose of the oil.
I have also been looking for a way of reducing odour due to different types of foods fried in the oil.
Fragrance oils are cheap either! So I was so happy when I came across your article recommending the use of vinegar to reduce the smell of the oil.
I will definitely try this. Thank you very much
can this sopa use to bath, for body?
hello, just want to ask….
If I want to add on coffee ground in this soap, is there any adjustment needed for other ingredient composition?
No adjustment is needed. You can just add in coffee ground /other flower etc as you like. Please limit it at 1%-2% max.
Can I know why do I need to leave it for 5 weeks?
can i replace the vinegar with coffee ground to reduce the odour(if yes, how many ground soap should i used?)? then i add green tea fragrance in saop.
Hi. Im so happy ti fund your website. In this soap for multupurpose use. Can you elaborate on the use. Thank you
Can soaps made out of used oil be used for the body?
Can any type of be used for this? Refined or mixed or anything? Because the regular oils need some proportions to get it right and hence asking. Thanks in advance.
I haven’t made any soap as yet.
Thank you for this helpful blog. I am eager to recycle used cooking oil gotten from restaurant for soap. I was surprised (and frankly disappointed) that in most videos where soap is made with used cooking oil, people used the resulting soap for other than bathing. From the look of your finished soap, it seems you are making this for bath use as well. Is my understanding correct? Second question: is there any reason your used oil was the only oil used in the soap? Why is a combination of oils not used in addition to the used oil? I am a new soaper and thought the combination of oils is important. Finally, thank you for noting how to deodorize using vineager.
The recipe turn out very well. I made soap out of 1/2 kg of used oil. My dishes and rugs are very clean after wash with the soap I made. Tq
Hi! Can you tell me what ingredient I can use to make it antibacterial soap? I will use it as my research and I will surely credit your idea for this. Thank you so much
