Yes lack of ingredients on the website is very annoying.
Interestingly if you look on the decleor UK website they will vaguely and exotically list as:
Coconut Oil, Meadowfoam Oil, Plant Glycoprotein, D Panthenol, Vitamin E Ester and Moisturising Agents
But go to the USA site and they seem to accommodate the more demanding American with:
Ingredients: WATER (AQUA), ISOPROPYL PALMITATE, COCOS NUCIFERA (COCONUT) OIL, GLYCERIN, SORBITAN STEARATE, PROPYLENE GLYCOL MYRISTATE, CYCLOPENTASILOXANE, LYSINE PCA, STEARETH-100, CETYL PALMITATE, LIMNANTHES ALBA (MEADOWFOAM) SEED OIL, CYCLOHEXASILOXANE, CETYL ALCOHOL, HYDROLYZED EXTENSIN, PROPYLENE GLYCOL, PANTHENOL, CARBOMER, TRIETHANOLAMINE, FRAGRANCE (PARFUM), TOCOPHERYL ACETATE, TETRASODIUM EDTA, PHENOXYETHANOL, METHYLPARABEN, ETHYLPARABEN, BUTYLPARABEN, PROPYLPARABEN, ISOBUTYLPARABEN
