It's possible you are thinking of:
* Acidic thickeners in food: These are often used to thicken sauces, jams, and other foods. Some common acidic thickeners include:
* Pectin: A natural polysaccharide found in fruits that gels in the presence of acid and sugar.
* Agar-agar: A natural polysaccharide derived from seaweed that forms a gel when cooled.
* Gelatin: A protein derived from collagen that gels when cooled.
* Acid-resistant thickeners in industrial applications: These are often used in applications where the thickener needs to be resistant to acidic environments. Some examples include:
* Polyvinyl alcohol (PVA): A synthetic polymer that can be used to thicken acidic solutions.
* Carboxymethylcellulose (CMC): A natural polysaccharide that can be used to thicken acidic solutions.
To give you a more specific answer, I need more context. Please tell me:
* What is the purpose of the acid thickener? (e.g., food, industrial application)
* What is the specific acid you are working with?
* What are the desired properties of the thickened solution? (e.g., viscosity, stability)
With more information, I can help you find the right chemical for your needs.
