I discovered DHC about 6 years ago when out of the blue I started receiving their catalogs. In each catalog they include several samples, which gave me the opportunity to try this unknown to me line. DHC is a Japanese skincare and makeup company that direct sales through their catalog and web site here in the United States. Apparently in Japan they are huge, with 180 retail stores and a presence in over 32,000 convenience stores. Yes, you can buy quality skincare products at the equivalent of a 7-Eleven in Japan. I'm jealous. Deep cleansing oil is DHC's top selling product worldwide and the first of their products that I purchased.
In the ingredient list, the only two I recognize are olive and rosemary leaf oil, so I looked up the others at a couple of cool sites that list cosmetic ingredients - Chemical of the Day and Cosmetics Ingredient Dictionary. Caprylic/capric triglyceride is fractionated coconut oil (which keeps it from becoming solid), and is considered an unadulterated natural ingredient because there are no solvents used. Sorbeth-30 tetraoleate is an emulsifier and pentylene glycol is a solvent or slip agent, and neither had high risk ratings. Phenoxyethanol is a common cosmetic preservative that is considered one of the less irritating ones to use in formulations, but one site did list it with an Environmental Working Group (EWG) risk score of 4 due to animal studies that show it to be a reproductive toxin. However, the EWG's Skin Deep Database is no longer online, so I'm not sure what's up with that. Tocopherol is the naturally occurring (vs. synthetic) form of vitamin E. Stearyl glycyrrhetinate is the fatty acid form of the anti-irritant glycyrrhetinic acid, which is derived from licorice. Looking up ingredients can be an eye opener, but I feel good about both the effectiveness and safety of this product.
