Does Mustafa sell citric acid powder?

I'm looking to make bath bombs and I'm not sure where to go. I thought to try mustafa, but it's so chaotic there I don't think I could find it there by asking the staff. Generally the shop's staff are competent in directing you to the general shopping sections but not at helping you find specific products. If mustafa doesn't have it where could I find it in Singapore? I believe it's used to can fruits - its AKA ascorbic acid.
