Combining these tests ensures that the physical and chemical properties of the oil ingredients and our final soap products are thoroughly examined. The thorough and continuous liaising between in-house chemists, an aromatherapist and a chromatherapist, ensure that oil and essential oil that fail these stringent tests are discarded immediately. The result of these tests guarantees that our customers obtain the greatest level of confidence in Merlin’s Soaps and receive only top quality products. We welcome our clients to visit our laboratory and see our quality control systems. We also cooperate with external laboratories for quality control purposes.
