I've been involved in the soap making process in GreenTech Biolab. We've been producing and labeling them for various brands in Thailand. These soaps are mostly Cold Process and Hot Processed. We do not encourage the use of chemical substances and prefers to use natural ingredients. Palm Kernel Oil, Coconut Oil, Olive Oil and Shea Butter are our specialty. For those interested may contact us directly at our email Support@greentechbiolab.com Have a nice day!
