What Is Ammonium Cocomonoglyceride Sulfate?
Ammonium cocomonoglyceride sulfate is a plant derived surfactant made by taking the fatty acids found in coconut oil, converting a portion of them into mono-glycerides, sulfating those molecules, then neutralizing the mix with ammonium hydroxide. The result is a water soluble powder or paste that carries a mild, skin friendly charge. First introduced in the late twentieth century as formulators searched for gentler alternatives to traditional sulfates, it quickly gained popularity in shampoos and body washes because it cleans without the harshness often linked to sodium lauryl sulfate. Today it shows up in facial cleansers, micellar waters, bubble baths, baby shampoos, foaming face masks, exfoliating scrubs and even some toothpaste style cleansers thanks to its ability to lift away dirt while producing a rich, creamy lather.
Ammonium Cocomonoglyceride Sulfate’s Cosmetic Benefits/Uses
This multitasking ingredient improves both the performance and feel of many rinse off formulas.
- Cleansing: Its surfactant structure binds to oil, makeup and surface debris so they can be rinsed away with water, leaving skin and hair feeling fresh and light
- Foaming: Creates a dense, stable lather that helps spread the product evenly, boosts the user’s sensory experience and assists in carrying away impurities
Who Can Use Ammonium Cocomonoglyceride Sulfate
Thanks to its coconut-derived, mildly charged structure, this surfactant works for most skin types. Normal, oily and combination skins generally tolerate it well, while sensitive or blemish-prone users often prefer it over harsher sulfates. Very dry or eczema-prone skin could feel a bit tight if the cleanser is left on too long or paired with other drying actives, so following up with a moisturizer is wise.
The ingredient is sourced from plant fats and neutralized with synthetic ammonium, so it is suitable for vegans and vegetarians provided the finished product is not tested on animals.
No data link it to hormonal disruption or fetal risk, so products containing ammonium cocomonoglyceride sulfate are usually considered safe during pregnancy and breastfeeding. This is not medical advice; anyone who is pregnant or nursing should still run new skincare past a qualified doctor.
The molecule does not absorb UV light or make skin more reactive to the sun, so it is not regarded as photosensitizing. It is also color-safe for hair and gentle enough for daily use when properly formulated.
Potential Side Effects/Adverse Reactions
Responses to topical ammonium cocomonoglyceride sulfate differ from person to person. The effects listed below are possible but unlikely for the average user when the ingredient is correctly formulated and used as directed.
- Transient dryness or tightness
- Mild redness or stinging on very sensitive or broken skin
- Eye irritation if the cleanser accidentally gets into the eyes
- Contact allergy resulting in itching, hives or swelling in rare cases
If any of these reactions occur stop using the product and seek advice from a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 1 out of 5
Ammonium cocomonoglyceride sulfate is a water soluble surfactant that rinses clean without leaving an oily or waxy film, which keeps pore blockage risk very low. Its molecules stay mostly on the surface and are removed with water during rinsing, so they have little chance to build up inside follicles. While any cleanser could leave skin tight if overused, this ingredient by itself is unlikely to trigger blackheads or whiteheads.
Because of its low rating it is generally suitable for people who are prone to acne or breakouts.
Formulas that combine this surfactant with heavy oils or butters may raise the overall comedogenic potential, so always consider the full ingredient list, not just a single component.
Summary
Ammonium cocomonoglyceride sulfate serves mainly as a cleanser and foam booster. Its surfactant structure grabs onto dirt, oil and leftover makeup, then allows them to be swept away with water. At the same time it whips up a creamy lather that spreads product easily and adds a pleasant feel during use.
The ingredient shows up often in modern shampoos, body washes and facial cleansers aimed at users who want the cleaning power of sulfates without the roughness linked to classics like sodium lauryl sulfate. It is not as famous as some bigger name surfactants but has carved out a steady fan base among formulators looking for mildness.
Safety data and long market history point to a low risk profile when used as directed. Still, skin is personal and reactions can differ, so it is smart to patch test any new product that contains this ingredient before making it part of a daily routine.
