Can you determine the percentage of "actives" in products just by looking at its ingredients list? For example, I'm trying to figure out the percentages of niacinimide, glucosamine and ascorbyl glucoside that a cream contains. The ingredients list is:
Water, Cyclopentasiloxane, Glycerin, Niacinimide, Acetyl Glucosamine, Polyethylene, Dimethicone, Soluble Collagen, Tocopheryl Acetate, Ascorbyl Glucoside, Aloe Barbadensis Leaf Juice, Bambusa Vulgaris Extract, Panthenol, Dimethicone Crosspolymer, Triethanolamine, C13-14 Isoparaffin, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Dimethiconol, DMDM Hydantoin, Laureth-4, Disodium edta, Laureth-7, Iodopropynnyl Butylcarbamate, Polyacrylamide, Fragrance, Titanium Dioxide, Mica.
Is there a way to figure it out or estimate or no? I know the ingredients usually are in higher amounts if they're near the top of the list and less near the bottom but that's all I know.  |

No, not really. Suppose the first ingredient (water) was 99.9%. That means the total of all the rest could only add up to 0.1%. But if water was 1%, their total would 99%. You need the actual recipe to know. Manufacturers won't give that out because if they have a successful product, anybody could easily copy it. |

| Glycerin is used at 2% to 5%, so everything after than is less. That product would not be very moisturising there are no emollients, only silicones as occlusives. Should feel silky tho. |

My understanding, and please correct me if wrong, is that US labelling requires ingredients to be listed in order of percentage concentration, ie, highest to lowest. With the exception of those of less than 1%, which can be listed in any order.
Which sounds fine in theory, except you don't know at what point in the ingredients list that 1% rule kicks in. |
