Does anyone know where to get pure Propylene Glycol or Glycerin in Bangkok?

I could order from iherb but their delivery prices to Thailand have increased a lot.

I want to use either to dissolve a little Salycilic Acid powder for application on skin. Salycilic Acid does not dissolve well in water. It dissolves well in ethanol but ethanol is too drying to the skin.

Here's some info on Salicylic Acid: https://www.makingcosmetics.com/Salicylic-Acid_p_51.html

I work with dairy cattle , and a problem we have  is Ketoses, which is when blood sugars run low ,due to sudden weight loss after calving, a cure is a drench of glycerin, which at one time was not easy to find.

I was in  chemists  shop at Victor Monument looking around ,and he had some  small bottles of  glycerin ,I asked if he had any large bottles ,he said no , for a cow you need about 1/2 Litar, so I gave that idea up .

So,try some chemists shop in town when asking for glycerin ,Thai's use the English  word.

This company ships within Thailand,  they are located in Bangkok

(122,123 Moo 1, Bangkraun, Bangkruay, Nonthaburi 11130)

 

 

Here is the web site , specifically glycerin, they may have it in larger quantities
