    Hi,  I’m trying to formulate an ointment well kind of copy one really… it’s used for psoriasis,seborrheic dermatitis, and dandruff but my husband finds it works well as a post shave kind of lotion/balm :) his neck chin less red and skin less irritable. The ingredients percentages I know are:

    Salicytic acid - 1.8%
    Sulphur - 5%

    Other ingredients which I do not know percentages are:
    Petrolatum - ?
    Paraffin - ?
    Corn starch - ?
    Fragrance - ?
    Oxyquinoline - ? (couldn’t get anywhere)
    Yellow No 11 - ?

    I decided to try a formula myself but it didn’t come out well at all to be honest too much Paraffin I think and husband said it started to burn a bit plus the ph level was in the reddish end so acid, so won’t be using that again :/  the formula I tried was:
    Salicytic acid -1.8%
    Sulphur- 5%
    Paraffin- 65%
    Beeswax- 15%
    Petrolatum- 10%
    Corn Starch- 2.5%
    Menthol- 2%

    I am finding it difficult to work out percentages for other ingredients and added beeswax as maybe a substitute for oxquinoline as could not get anywhere well except russia so thought I’d leave that….finding it difficult to work out ingredient percentages…any help appreciated

    In my opinion, as a man, your husband would be better off improving his shaving technique so as not to have the problem in the first place.

    You will find that the product is mostly petrolatum with smaller amounts of the other ingredients. 
    This might help
    The amount of menthol seems to be very high and is probably causing the burning sensation.

    Menthol at 1.5% is usually a maximum for a balm if you don’t want it to be too irritating. I think 0.5-1% is ok.

    Welcome. On second thoughts, I usually don’t go light on menthol, but I think even 0.1% could possibly be felt on the skin.
