Ren's range of chemical free skincare
Here are the things that they refuse to add to their products:
Glycols and diglycols (such as propylene glycol), PEG's, PPGs, urea,
D.E.A, T.E.A, PABA and other synthetic sunscreens, aliphatic
alcohols/hydrocarbons, phthalates, fumarates, amines, alkanolamines,
synthetic AHAs/BHAs, polyacrylamide, metacrylate, elastomer, poloxamer,
styrene, vinyl, polyquaternium, synthetic chelating agents, nylon,
nitriles, nitrates, nitrosamine releasers, bromates, fluor, aluminum
Looks like a list of some the things that Sarah may have experimented with in wilder days.
Ren's products, by and large, contain what they claim to. Take the Damask Rose Body Cream. The base ingredient is damask rose flower water. Then there are various palm and coconut oils and that's about it. The preservative is phenoxythanol (this can be an irritant, but apparently only in significant concentrations).
