Considering adding glycolic acid to your skincare routine but wondering if it fits with your vegan lifestyle?
Glycolic acid, an alpha hydroxy acid (AHA), can be synthesized through several methods, including chemical reactions with formaldehyde or chloroacetic acid, and enzymatic processes. It can also be naturally sourced from sugarcane, sugar beets, and fruits like pineapple. Given these methods of production, most glycolic acid is considered vegan, as it is not derived from animal sources.
In the following sections, we’ll dive into the details of glycolic acid and its application across different industries.
What Exactly Is Glycolic Acid?
Glycolic acid is an alpha hydroxy acid (AHA), which is a widely recognized component in the skincare industry, though it’s also used in the textile industry as a dyeing and tanning agent.
Understanding its synthesis and origin is critical for vegans like us who would rather opt for cruelty-free alternatives.
Several methods have been developed to create glycolic acid:
Formaldehyde Synthesis: The most prevalent method involves a catalyzed reaction between formaldehyde and synthesis gas, commonly referred to as the carbonylation of formaldehyde. This process is favored due to its cost-effectiveness.
Chloroacetic Acid Reaction: Another method includes the reaction of chloroacetic acid with sodium hydroxide. This is followed by a re-acidification process to derive glycolic acid.
Alternative Procedures: While not predominantly in use, there are other methods such as the hydrogenation of oxalic acid and the hydrolysis of cyanohydrins derived from formaldehyde. Notably, some glycolic acid products are manufactured without formic acid.
Natural Extraction: Glycolic acid can also be sourced directly from natural entities, including sugarcane, sugar beets, pineapple, cantaloupe, and unripe grapes.
Biochemical Enzymatic Process: Recent advancements have paved the way for an enzymatic biochemical process, which is considered more energy-efficient in producing glycolic acid.
The majority of synthesis processes for glycolic acid, particularly the predominant ones, do not involve animal-derived ingredients.
Additionally, when glycolic acid is sourced from natural sources, it is always a fruit, which means that glycolic acid is vegan.

How Is Glycolic Acid Used Across Different Industries?
Glycolic acid isn’t just a popular skincare ingredient; its varied properties have made it a valuable component across several sectors.
Here’s a quick snapshot of its uses in different industries:
Skincare and Beauty:
- Rejuvenating Agent: Glycolic acid clears away dead skin cells, brightening the complexion.
- Combatting Age: Found in anti-aging products, it smooths out wrinkles and promotes firmer skin.
- Evens Out: It’s a champion at reducing skin discoloration and refining texture.
Medical Uses:
- Clear Skin Solutions: At higher doses, it becomes a powerful treatment for acne and conditions like melasma.
- Plump It Up: Some skin fillers have glycolic acid to boost collagen and restore a youthful look.
Textiles and Leather:
- Dye Helper: It assists with dyeing textiles evenly.
- Leather Prep: It’s also used to tan leather. I’m assuming this is also used when it comes to faux or vegan-friendly leather.
Industrial Cleaning:
- Deep Clean: Scaled boilers? Rusty equipment? Glycolic acid helps cleanse and restore.
In Our Food:
- Taste and Preservation: Occasionally, it enhances flavors or acts as a preservative.
As you can see, glycolic acid is a multifaceted ingredient with various applications, even in areas where you might not even realize it.
This is why I think it’s important to truly know what an ingredient is really all about— because you may be consuming/using it in different areas of your life, even though you may not agree with how it’s made.
What’s The Bottom Line?
When we think of glycolic acid, our minds often jump to skincare — envisioning glowing, refreshed faces post-exfoliation.
However, as we’ve seen, this compound plays many roles. From the intricate processes of textile dyeing to the meticulous cleansing in industrial setups, and even finding its way into our medical treatments, glycolic acid is used extensively.
For vegans like us, it’s reassuring to know that its production, often derived from non-animal sources like sugarcane or through chemical syntheses, aligns with ethical consumerism.
