Label Check
I am an amatuer Cosmetic Chemsits, mostly make things for fun. Currently I am in college pursuing a degree in statistics and we are required to do a mock ANOVA analysis of some data (either personally collected or from the internet) as a graduation requirement. I was inspired by the LOI shampoo post to conduct an “experiment” (I use quotations because I don’t have the time to perform a proper SRS, but everything will be properly controlled) to determine if non-functional, vanishingly small amounts of products actually do significantly affect the consumers perception of products (in this case, a simple facial cleanser). Inasmuch, here are the two formulations I am considering:Water, Decyl Glucoside*, Sodium Laureth Sulfate*, Cocamidopropyl Betaine*, PEG-50 Shea Butter^, Fragrance, Citric Acid, Propylene Glycol, Diazolidinyl Urea, Methylparaben, Propylparaben*Gentle Cleaninsing Agens, Emollient/MoisturizerWater, Decyl Glucoside*, Sodium Laureth Sulfate*, Cocamidopropyl Betaine*, PEG-50 Shea Butter^, Persea Gratissima (Avocado) Oil^, Simmondsia Chinensis (Jojoba) Seed Oil^, Limnanthes Alba (Meadowfoam) Seed Oil^, Hippophae Rhamnoides (Sea Buckthorn) Fruit Oil^, Tocopheryl Acetate^^, Aloe Barbadensis Leaf Juice, Panthenol**, Ascorbyl Palmitate^^, Glycerin***, Polysorbate 20, Fragrance, Citric Acid, Propylene Glycol, Diazolidinyl Urea, Methylparaben, Propylparaben*Gentle Cleansing Agents, **Pro-vitamin B5, *** Hydrating, Skin Repairing agent, ^ Emollients/Moisturizers, ^^ Vitamin E (anti-oxidant), ^^^ Vitamin CDoes anyone on the formu have any other suggestions for the study, and can anyone make sure I have labeled the lists correctly? On a final note, when adding the descriptive content to the ingredients, for example “^Emollients/Moisturizers”, must this be done at the end, or can it be done in parenthesis in the LOI, eg: Persea Gratissima (Avocado) Oil (Moisturizer). I am leaning to the former…Incase anyone is curious, the functional level I have decided on is .02%, polysorbate will be 1% to solubilize. Per labeling guidelines, however, even though the amount of polysorbate and preservative will far exceed the amount of emollients, I am listing them first as all will fall under 1%. This way, when the subject is asked the read the LOI, they see these ingredients first.Thanks for the time, guys! Looking forward to seeing your suggestions

I think that those explanations at the bottom would be very confusing to most people. I’d try using a table underneath the LOI instead, since the FDA regs about what can be included in a LOI are very strict.
Also consider that consumers are being told that fewer ingredients are better, so you might want to include that in your questionare. -
Yes, your ingredient lists are pretty much right the way they are now. You are not allowed to put functional descriptions within the ingredient list.
I’m not really sure what you are trying to accomplish though. What question are you trying to answer in your study? -
The study is basically to determine if the length of an ingredient list can positively effect your perception of the product. There are four groups (1) Read/Use Long, (2) Read/Use Short, (3) No Read/ Use Long. (4) No Read/Use Short. Theoretically, there should be no difference between (1) and (3) and (2) and (4). Also, as a whole there should be no difference between groups (1)(2) and (3)(4). I will perform a two way ANOVA to test this once the data are fully collected.
