Is Redken Fresh Curls Curl Boost Scrunching Spray Gel CG?
 

Here are the ingredients:

Water (Aqua), Sodium Polystyrene Sulfonate, Glycerin, PPG-5-Ceteth-20, PPG-5-Ceteth-10 Phosphate, Phenoxyethanol, Sclerotium Gum, Methylparaben, Triethanolamine, Ethylparaben, Calcium Gluconate, Honey/Mel, Disodium EDTA, Fragrance (Parfum), Arginine, HCl, Coconut Oil/Cocos Nucifera, Taurine, Oleth 10, Disodium Cocoamphodipropionate, Lecithin, Hydrolyzed Sweet Almond Protein, Phosphoric Acid, Olive Fruit Oil/Olea Europaea.

Yes, as far as I can tell it is CG. I have been using it so I pored over the ingredients first and didn't see anything non-CG in there when I looked at the bottle, or in the list you posted.
