Which of these ingredients could cause eye irritation?

Hydrolyzed Jojoba Ester
Sodium PCA
Caprylic/Capric Triglyceride
Glyceryl Stearate
Ceramide NP
Cholesterol 1%
Cetearyl Alcohol, Coco-Glucoside
Lauric Acid 0.5%
Linoleic Acid, Linolenic Acid (liquid) 1%
Dimethicone cps 1000
Hyaluronic Acid <50,000 Daltons
Panthenol 1%
Sodium Ascorbyl Phosphate 1%
Cholecalciferol (Vitamin D3, 400 IU pr gram)

Have an issue with a formula that's can cause some eye irritation 10-30 minutes after application, presumably from an ingredient migrating through the skin, any idea what could be causing it of the ingredients above?

    What is the pH?

    Thanks, the I think the blends of acids and emulsifier are prime candidates to test then, perhaps starting with the acids.

    Since dimethicone is so broadly used I doubt it is it.

    pH is around 6.

    Hyaluronic Acid <50,000 Daltons

    If this is Hyacare 50, my eyes are very sensitive to this ingredient.

    Update on this! I tested another formula with few common ingredients

    Cholecalciferol (Vitamin D3, 400 IU pr gram)
    Dimethicone CPS 1000 and
    Hyacare 50 aka Hyaluronic Acid <50kDa

    I don't think it's vitamin d3 as I used it in an older formula that also had this issue, dimethicone is so widely used that I think it's fairly certain it's the HA. What other options do I have?
