A good product is not only the effective ingredients, but the others.
The Elixir only has 10 ingredients (not includes water). We use Hydroxyacetophenone, natural preservative with only 0.5% to keep the product safe from bacteria.
-Propanediol, Butylene Glycol, and 1,2-Hexanediol which are the family of alcohol. But they don’t irritate skin as ethanol, aka alcohol, does. Instead, these three ingredients can keep the water on the skin and enhance the preservative system to prevent from bacteria. Also, Propanediol, 1,3-propanediol, is from corn resource that is different from Propylene Glycol, 1,2-propanediol, that is from oil refinery resource and may cause irritation to skin.
-PEG-60 Hydrogenated Castor Oil is an emulsifier for Bisabolol to assist it dissolve in the water solution. It is very common emulsifier in beauty industry. EWG categorized it as a moderate hazard because of the impurities of Ethylene Oxide and 1,4-Dioxane that may cause cancer with high dose. But we don't see it hazardous after we checked the amount of the impurities and researched a lot of results from the scientific papers, like International Journal of Toxicology. The impurities quantity as less than 0.001% that wouldn't cause a concern. While the pros of using this emulsifier weighs heavier than the cons, we take the opinions of EWG web as a reference but won't be bothered after we evaluate it as a safe ingredient.
-Sodium Hyaluronate here is humectant to catch the moist on the skin and thickener to make the elixir a bit gel-like.
