What Is Acetyl Carboxymethyl Cocoyl Glycine?
Acetyl Carboxymethyl Cocoyl Glycine is a specialty ingredient created by reacting coconut acid chloride with the amino acid glycine and chloroacetic acid. The coconut part contributes a lightweight fatty residue while glycine supplies a skin friendly backbone. The result is a mild, water soluble molecule that carries both fatty and acidic groups, allowing it to mix well with oils and water based phases.
The compound first appeared in the late 1990s when formulators looked for plant sourced alternatives to traditional synthetic chelators. Coconut oil was an obvious choice because it is abundant, renewable and already popular in beauty products. By attaching the small amino acid glycine and adding a carboxymethyl group, chemists produced a gentle ingredient that could control metal ions without the harshness sometimes linked to older chelators like EDTA.
Manufacturing involves converting coconut fatty acids into acid chloride, then carefully adding glycine. A final step with chloroacetic acid introduces the carboxymethyl part, giving the molecule its metal binding power. The finished material is usually supplied as a clear liquid or fine powder that dissolves easily in water.
You will spot Acetyl Carboxymethyl Cocoyl Glycine most often in facial cleansers, micellar waters, shampoos, lightweight moisturizers, sheet masks and leave on lotions aimed at sensitive or acne prone skin. Its mild nature and coconut origin make it attractive for natural inspired lines and baby care products as well.
Acetyl Carboxymethyl Cocoyl Glycine’s Cosmetic Benefits/Uses
In skin and hair care formulas this ingredient serves chiefly as a chelating agent. By binding trace metals such as calcium, iron and copper it prevents unwanted reactions that can cause product discoloration, rancidity or loss of fragrance. Better control of metal ions helps preservatives work more efficiently and keeps textures smooth and stable, so the product stays fresh longer and feels pleasant on the skin or scalp.
Who Can Use Acetyl Carboxymethyl Cocoyl Glycine
This gentle chelating agent is generally well tolerated by all skin types including sensitive, oily, combination and dry because it is mild and water soluble rather than heavy or greasy. Extremely dry skin may still need richer emollients alongside it for extra comfort but the ingredient itself poses no special concern for that group.
Acetyl Carboxymethyl Cocoyl Glycine is derived from coconut and synthetic amino acid sources with no animal-derived components so it suits both vegans and vegetarians. Most suppliers also certify it as cruelty free.
No data show a risk to women who are pregnant or breastfeeding when the ingredient is used topically in cosmetic amounts. Absorption through intact skin is minimal yet this is not medical advice and anyone who is pregnant or nursing should review all skincare products with a qualified health professional before use.
The ingredient does not increase photosensitivity and there are no known interactions with sunlight or UV exposure. It is compatible with common actives like niacinamide, vitamin C and retinoids so formulators can slot it into a wide range of routines without worry.
Potential Side Effects/Adverse Reactions
Reactions to topical Acetyl Carboxymethyl Cocoyl Glycine can vary from person to person. The following points outline potential side effects but they are uncommon when the ingredient is used at normal cosmetic levels and most people will experience none of them.
- Mild redness or transient irritation, especially on very reactive skin
- Stinging if applied to broken or over-exfoliated areas
- Rare cases of contact dermatitis in individuals sensitive to coconut derivatives or glycine compounds
- Watery eyes if the product accidentally enters the eye area
If any of these reactions occur stop using the product and consult a healthcare professional or dermatologist for guidance.
Comedogenic Rating
Rating: 0 / 5
Acetyl Carboxymethyl Cocoyl Glycine is water soluble and used in very small amounts, so it leaves almost no oily film that could block pores. The coconut portion is chemically altered and does not behave like raw coconut oil, which is why the ingredient is considered non comedogenic.
Suitable for acne-prone and breakout-prone skin.
Because it helps keep formulas stable and fresh, it may even support a clearer routine by preventing the breakdown of other ingredients that could irritate skin over time.
Summary
Acetyl Carboxymethyl Cocoyl Glycine acts mainly as a chelating agent, grabbing onto trace metals such as calcium, iron and copper so they cannot spoil color, scent or texture. By binding these metals it boosts preservative performance and keeps products smooth and long lasting.
It is not a superstar buzzword yet it has a steady following in gentle cleansers, toners and baby care where a mild plant-based chelator is valued. Many natural and vegan brands pick it for its coconut origin.
Overall safety is high. It is non comedogenic, non sensitizing for most users and has no known issues with sun exposure or common actives. As with any new skincare ingredient it is wise to do a quick patch test before using a full-sized product, just to be sure your skin agrees with it.
