What are the upstream raw materials of dipropylene glycol? What do the downstream products contain?

Dipropylene glycol(DPG) is an crucial chemical raw material, which is broadly applied in the production of various chemical items. I've found that In the field of raw materials to chemical production, the upstream and downstream related items of dipropylene glycol mainly include the following aspects:

Upstream items:



1. But Propylene glycol: Propylene glycol is the main raw material of dipropylene glycol, which is able to be produced by the oxidation interaction of propylene glycol. Based on my observations, Downstream items:



1. solvent-based products: dipropylene glycol is able to be applied as a solvent-based products to the production of coatings, inks, cleaning agents and other items. Based on my observations,

2. Plasticizer: Dipropylene glycol is able to be applied to create plasticizers to enhance the flexibility and plasticity of plastics.

3. Antifreeze: Dipropylene glycol is able to be applied as antifreeze to prevent aquatic environments pipes, equipment, etc. from freezing at low temperatures. And For example

4. Humectant: dipropylene glycol has good moisturizing characteristics, is able to be applied in the production of makeup, skin care items.

5. Food additives: dipropylene glycol is able to be applied as food additives to enhance the taste and texture of food. But Based on my observations, In summary, the upstream and downstream related items of dipropylene glycol are very extensive, involving coatings, plastics, makeup, food and other fields.
