Many companies proudly boast that they do not test their products on animals. Nonetheless, despite the fact that they don't test their finished products on animals, there isn't a company selling a sunscreen or using vitamins or myriad plant extracts in their products that doesn't know about the efficacy of these ingredients based on recent or current animal testing. While it is wonderful that companies like Beauty without Cruelty do not test their products on animals, as is true for many companies, a good many of their formulations are a result of animal research. If Beauty without Cruelty does excel in one area, it is that none of their products are sourced from animals. That is somewhat unique in the industry and definitely a plus for vegans.
More troubling in hair care products than silicones are Cationic Polymers. These ingredients like Guar Hydroxypropyl Trimonium Chloride or Polyquaternium-10 have been demonstrated to build up on hair. They ionically bond to hair and you do need to shampoo more to get them off. Silicones don't stick nearly as well as those ingredients.
I wonder why there is no controversy about Cationic Polymers?
...refined shea butter has usually been extracted from the shea kernels with hexane or other petroleum solvents. The extracted oil is boiled to drive off the toxic solvents, and then refined, bleached, and deodorized, which involves heating it to over 400 degree F and the use of harsh chemicals, such as sodium hydroxide. Shea butter extracted in this manner still contains some undesirable solvent residues, and its healing values are significantly reduced. Antioxidants or preservatives such as BHA (butylated hydroxyanisole) or BHT (butylated hydroxytoluene) may be added as well. The end result is an odorless, white butter that may be aesthetically appealing, but lacks the true moisturizing, healing, and nutritive properties of true traditional shea butter. In addition, refined shea butter is often hard and grainy, not smooth and creamy like pure, unrefined shea butter. All that can be said for refined shea butter is that it has an extended shelf life, a white, uniform color, and no odor.

Humectants absorb water and hold in moisture. They are absolutely crucial in a conditioner for curly hair. Panthenol, vegetable glycerine, and sorbitol are just a few humectants to look for on the label.
