I finally decided to post this question, as it has been bothering me for a long time and I have never been able to find out the answer to it. This is still just a hobby for me, but I would still like to know the official way of doing things :-)
My confusion is about the INCI label. I understand the general idea, what kind of names to use and that the ingredients should be labeled in descending order until 1%, after which they can be in random order. I also understand labeling perfume, flavor and pigments. What I don’t understand is if I have an ingredient which is not just one raw material, but a combination of raw materials, how am I going to label that?
I’ll give an example that I’m just making up as I’m writing this, so please don’t pay much attention to the formula :-) This is just to understand how the INCI is written and deliberately choosing certain type of ingredients to understand this better.
So let’s say my formula is this with the brand names of the ingredients and their percentages:
water q.s. to 100%
olive oil 10%
hydrating complex 4%
olivem 1000 3%
xanthan gum 0.3%
The ingredients’ own INCI labels are as follows:
hydrating complex = aqua, sodium lactate, sodium PCA, glycine, fructose, urea, niacinamide, inositol, sodium benzoate, lactic acid
olivem 1000 = cetearyl olivate, sorbitan olivate
preservative = benzyl alcohol, dehydroacetic acid, aqua
What should the INCI label for the lotion look like? Mind you, I live in EU, if that makes any difference, but what I’ve read thus far, it doesn’t seem to in this case.
I didn’t include an ingredient here, where the INCI would have the (and) instead of a comma, but it would be nice to know how to handle those as well. I remember reading somewhere that the (and) is just replaced with a comma, but I’ve also seen products where the (and) has been retained.
I’m guessing that aqua isn’t going to be written three times nor is urea written twice. What I am confused about is, will all the ingredients in the hydrating complex (minus aqua and urea) be written at the 4% “mark”, before the olivem 1000 ingredients? Even though it’s likely that there is more cetearyl olivate in the product than niacinamide? Since I’m only a hobbyist, I don’t know if it’s possible to have access to how much each raw material has been used to make each ingredient.
I am so hoping I could finally understand this, because it is making me nuts :-) I’m also toying with the idea of setting myself a web based application for formulating purposes (I'm a nerdy girl) and it would be nice if the application could create the INCI label for me, but I need to know the logic behind it first!
Thank you! :-)
