People think we’re opposed to natural ingredients because we’re in bed with the “Big Chemical Companies.” Just for the record, the Beauty Brains are independant-minded skeptics and we are NOT in bed with any chemical companies. (Except maybe for Sarah Bellum, I can’t keep track of everyone she’s been in bed with, but I digress…) All we require to believe a natural ingredient works is reasonable test data that proves its efficacy. Today’s example of a natural ingredient that has such test data is radish oil.
Oil obtained from the Daikon radish (aka Raphanus Sativus (Radish) Seed Oil) is marketed by Natural Plant Products . This oil has a nice sensory feel similar to esters and silicone type emollients and testing has proven it’s a good skin moisturizer because it reduces trans-epidermal water loss (TEWL). The results show that it increases skin barrier function similar to isopropyl palmitate, a synthetic ester typically used in lotions. It also may be a good replacement for silicone in hair products although we haven’t seen this test data.
Even though the testing was conducted by the manufacturer and we haven’t seen the complete studies, I’d still put more faith in an ingredient with a plausible mode of action and some test data over all the “pixy dust” ingredients that have no scientific basis for working at all. If you see any products with radish oil let us know and we’ll take a look at them for you.
