Hey guys, since I am not very well educated in cosmetic chemistry, I was wondering perhaps someone could help me to analyse the ingredients of this refreshing face tonic. What's good, what's bad? Thanks in advance
Aqua, Glycerin, Aloe Barbadensis Leaf, Potasium Carbonate, Propylene Glycol, Diazolidinyl Urea, Methylparaben, Propylparaben, Polysorbate 20, Disodium EDTA, Allantoin, Parfum (Benzyl Benzoate, Butylphenyl Methylpropional, Hexyl Cinnamal, Limonene, Linalool)
"Good" and "bad" are quite subjective, and imho also related to the price you are paying for it. I'm no cosmetic chemist either, but, general comments on the ingredeint list are:
Aqua - distilled water = expected top ingredient for a toner
Glycerine - humectant = good, underated, basic moisturiring ingredient at a maximum of 5% total product
Aloe Barbadensis - humectant, anti-inflammatory etc = moisturising ingredient that some people like, some people don't (I don't). Eitherway, it's placed after glycerine in the list so is probably included in an amount insufficient to do much good (i.e. likely <5%)
Potassium Carbonate - pH adjuster = used to balance the acidity level of the product so it's skin-friendly and doesn't make you feel dry
PG/Diaz.Urea/Methyl-&Poly-paraben - presevative = "Germaben II" preservative sustem, good basic all-round preservative if you're not worried about the alleged carcinogenic properties of parabens. Used at a maxiumum dosage of 1% final product I wouldn't worry about it too much although there are alternative preservatives with less publicity attached to their ingredients
Polysorbate 20 - emulsifier = used to mix the oil-based fragrance in this product with the water-based "main" ingredients
Disodium EDTA - chelating ingredient = used to isolate the metal ions which can accumulate especially in plant matter (the aloe & allantoin) to stop them from damaging the skin - used at 0.2% max
Allantoin - anti-irritant/inflammatory = nice soothing ingredient found in many dry/sensitive skin products however it generally needs to be in 0.5%-2% to do much good. Here, it's placed in the list after Disodium EDTA so probably <0.2% which doesn't do much good...althouth it may be more than that as most countries allow ingredients <1% to be listed in any order (not necessarily in descending order). In any case it can't physically be incorporated in a solution at > 0.5% so unlikely to have huge impact here
Parfum - fragrance = I see no need for a potentially sensitising ingredient in this; the other ingredeints shouldn't smell that bad to justify it
The ingredient cost must be maximum 50 cents (US) per 1 liter of product I guess, plus packaging cost on top of that. (Of course, it's reasonable to expect a company to add distribution, marketing, labour, legal etc etc etc costs on top of that).
So, if you like it and it's very cheap, great! otherwise, I'd probably skip it
