What Is Mucor Circinelloides Glycerides?
Mucor Circinelloides Glycerides is a blend of mono-, di- and triglycerides that comes from the oil of the fungus Mucor circinelloides. The fungus is grown in large tanks where it turns simple sugars into a rich oil. Chemists then split the oil and attach glycerin to create the glycerides found in skin care.
Interest in fungal oils began in the 1990s as brands looked for plant-free and more ecological fat sources. Because the fungus can be fermented year-round without farmland or harsh weather limits, its oil soon found a spot in cosmetic labs. The resulting glycerides feel similar to well-known plant butters yet are lighter and easier to spread.
To make the ingredient, the fermented oil is extracted, filtered and cleaned. It is then mixed with food-grade glycerin under heat so the fatty acids bind to the glycerin. After further purification the final waxy liquid is ready for use.
Formulators add Mucor Circinelloides Glycerides to face and body moisturizers, night creams, anti-aging serums, masks, lip balms and makeup primers. It works well in both water-based and anhydrous products, making it a flexible choice for many textures.
Mucor Circinelloides Glycerides’s Cosmetic Benefits/Uses
This ingredient has one key function in skin care products.
As an emollient, Mucor Circinelloides Glycerides softens and smooths the skin surface. It fills in rough spots, reduces flakiness and leaves a supple feel without a heavy or greasy aftertouch.

Oily or acne-prone skin can also use it thanks to its light texture, though those who break out easily may prefer to try it in lower amounts first to make sure it feels comfortable.
The ingredient is sourced from a fermented fungus and processed with plant-based glycerin, so it is suitable for vegans and vegetarians looking to avoid animal fats.

Comedogenic Rating
Rating: 1 / 5
Mucor Circinelloides Glycerides is made up of short to medium chain fatty acids that absorb quickly and leave little residue so it is unlikely to block pores in most users. The fermentation-derived oil is also highly refined which removes impurities that could encourage clogging.
Because of its low rating it is generally suitable for people who are prone to acne or breakouts, especially when it appears near the end of an ingredient list.
If paired with heavier waxes or butters the overall formula may feel richer and raise the chance of congestion so always consider the full product composition.
Summary
Mucor Circinelloides Glycerides acts mainly as an emollient that smooths rough patches, reduces flakiness and helps other actives spread evenly by creating a silky glide. It achieves this by filling the tiny gaps on the skin surface with lightweight fatty molecules that mimic skin’s own lipids.
While still a niche ingredient compared with classic plant oils its eco-friendly fermentation process and agreeable skin feel are slowly boosting its presence in modern moisturizers and makeup.
Current research and real-world use point to a high level of safety with only rare irritation or allergy reports. As with any new cosmetic it is wise to patch test a small area first to make sure your skin agrees with the formula.
