What Is Macadamia Seed Oil Polyglyceryl-6 Esters?
Macadamia Seed Oil Polyglyceryl-6 Esters is a plant-derived ingredient created by linking nourishing macadamia seed oil with polyglycerin-6, a chain of six glycerin molecules. The pairing balances the rich fatty acids of the oil with the water-loving nature of polyglycerin, giving a versatile material that loves both oil and water. Macadamia oil has been prized since the 1970s for its lightweight feel and high levels of palmitoleic acid, a fatty acid also found in youthful skin. Polyglyceryl technology became popular in the 1990s as brands looked for gentle, biodegradable alternatives to petrochemical surfactants. Bringing the two together produced an ingredient that softens skin, mixes oil and water and helps cleanse without harshness.
The ester is made through transesterification: macadamia seed oil and polyglycerin-6 are heated with a food-grade catalyst, then purified. The finished material is 100 percent plant based and readily biodegradable.
Thanks to its balanced character you will spot Macadamia Seed Oil Polyglyceryl-6 Esters in facial cleansers, micellar waters, moisturizing lotions, lightweight creams, baby care products, makeup removers and leave-on masks. It also appears in anti-aging formulas that aim to deliver nourishment without a greasy afterfeel.
Macadamia Seed Oil Polyglyceryl-6 Esters’s Cosmetic Benefits/Uses
This multi-tasker brings several helpful roles to a formula
- Skin conditioning: leaves skin feeling soft smooth and comfortable while helping reduce flakiness
- Emollient: provides a silky slip that improves spreadability and cushions the skin without heaviness

Who Can Use Macadamia Seed Oil Polyglyceryl-6 Esters
This ingredient is gentle enough for most skin types. Dry skin enjoys its softening fatty acids, oily and combination skin appreciate the light non greasy feel while sensitive skin benefits from its mild cleansing action. There are no known reasons for those with normal skin to avoid it. People with a confirmed tree nut allergy should proceed cautiously since the base oil comes from macadamia nuts, even though the risk of proteins that trigger reactions is very low after processing.
Because it is made entirely from plant sources and contains no animal by-products it suits both vegans and vegetarians.
Current safety data show no issues for pregnant or breastfeeding women when used topically in normal cosmetic amounts, yet this is not medical advice. Anyone who is expecting or nursing should check with their doctor before starting a new product just to be safe.
Macadamia Seed Oil Polyglyceryl-6 Esters does not increase photosensitivity, so it will not make skin more prone to sunburn. It is also odorless which makes it a good choice for people who avoid fragrance.
Potential Side Effects/Adverse Reactions
Side effects from topical use can vary from person to person. The points below list potential reactions but they are uncommon when the ingredient is used at normal levels in well formulated products.
- Mild irritation such as stinging or itching, especially on very sensitive skin
- Redness or a slight rash in rare cases of individual sensitivity
- Allergic response in those with severe macadamia nut allergy
- Tiny whiteheads or clogged pores if a product is over applied or not rinsed off fully
- Eye discomfort if the cleanser form gets into the eyes
If any negative reaction occurs stop using the product and consult a healthcare professional
Comedogenic Rating
Rating: 1 out of 5. While raw macadamia oil sits around a 2, linking it to polyglycerin-6 makes the molecule more water compatible so it spreads thinly and rinses away with ease. This limits the chance of residue that can block pores. Most acne prone users find it lightweight and non occlusive enough for daily use, though extremely oily skins may still prefer a completely oil free option. Because the ingredient helps emulsify excess sebum it can even assist cleansers in keeping pores clear.
Summary
Macadamia Seed Oil Polyglyceryl-6 Esters softens skin, adds a silky emollient finish, lifts away dirt and makeup and holds oil and water together in stable formulas. It delivers these perks by pairing the fatty acids of macadamia oil with the water loving nature of polyglycerin, giving a molecule that slips into both oil and water phases.
The ingredient is gaining traction in gentle cleansers, micellar waters and light moisturizers but it is still less common than classics like glyceryl stearate or PEG emulsifiers. Brands focused on plant based and sensitive skin friendly formulas are the main adopters.
Current data show it to be very safe for topical use with a low allergy risk and minimal comedogenicity. As with any new cosmetic, perform a quick patch test before full application just to be on the safe side.
