What Is Peg-70 Mango Glycerides?
Peg-70 Mango Glycerides is a plant derived ingredient made from the seed oil of the mango tree, Mangifera indica. Chemically it is a mix of mono and diglycerides that have been reacted with about seventy units of ethylene oxide. This process, called ethoxylation, adds a chain of water loving groups to the naturally oily glycerides, turning them into a molecule that can mix oil and water with ease.
Interest in mango seed oil grew in the 1990s as brands looked for upcycled raw materials from the food industry. Chemists soon found that by converting the leftover seed butter into ethoxylated glycerides they could create a mild surfactant that comes from a renewable source. The resulting Peg-70 Mango Glycerides has been used ever since in products that need a gentle cleansing or emulsifying agent.
The ingredient is made in two main steps. First the mango seed butter is split into mono and diglycerides through controlled heating with food grade glycerin. Next these glycerides are reacted with ethylene oxide under pressure to attach the hydrophilic polyethylene glycol chains. After purification the viscous liquid is ready for use in cosmetic formulas.
You will often find Peg-70 Mango Glycerides in face or body cleansers, micellar waters, eye makeup removers, shampoos, shower gels, creamy facial masks, lightweight lotions and even sun care products where a stable oil in water texture is required.
Peg-70 Mango Glycerides’s Cosmetic Benefits/Uses
Formulators reach for this ingredient because it can perform more than one job in a single formula.
- Cleansing – Its surfactant nature loosens dirt, excess oil and makeup so they can be rinsed away with water, helping leave skin and hair feeling fresh without a tight after feel
- Emulsifying – It bridges the gap between water and oil phases, creating stable, smooth creams or lotions that resist separation and feel light on application
Who Can Use Peg-70 Mango Glycerides
Thanks to its mild nature Peg-70 Mango Glycerides works for most skin types including dry, normal, sensitive, oily and combination. Its gentle cleansing action removes grime without leaving skin feeling stripped, which is why even reactive complexions usually tolerate it well. Those with severely compromised or broken skin barriers should still take extra care, as any surfactant can cause stinging on open or cracked areas.
The ingredient is sourced from mango seed oil and contains no animal-derived material, making it suitable for both vegetarians and vegans. The ethoxylation step relies on synthetic chemistry rather than animal inputs.
Current safety data show no specific risks for women who are pregnant or breastfeeding when Peg-70 Mango Glycerides is used topically in a finished cosmetic. This is not medical advice, and anyone who is expecting or nursing should run their skincare choices past a qualified doctor to be safe.
Peg-70 Mango Glycerides does not make skin more sensitive to sunlight and has no known effect on melanin or tanning. It is also odorless, so it will not clash with fragrances or create an unwanted scent in fragrance-free formulas.
Potential Side Effects/Adverse Reactions
Side effects from topical Peg-70 Mango Glycerides can vary from person to person. The points below list potential reactions that could occur, but they are uncommon when the ingredient is used at appropriate levels in well-formulated products.
- Mild skin irritation such as temporary redness or itching in very sensitive individuals
- Eye irritation if the product accidentally enters the eyes while cleansing
- Allergic contact dermatitis in users with a rare sensitivity to mango derivatives or polyethylene glycol components
- Excessive dryness or tightness when high concentrations are left on skin or when over-cleansing strips natural oils
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
Peg-70 Mango Glycerides is highly water soluble because of its long polyethylene glycol chains, so it rinses off cleanly and does not linger in pores. The base mango seed glycerides are lightweight and chemically modified to be more hydrophilic, which further reduces any tendency to clog follicles. Trace amounts of fatty material remain, giving it a very low but not entirely zero chance of causing congestion.
This low score means the ingredient is generally suitable for acne-prone or breakout-prone skin when used in rinse-off or leave-on products formulated at typical levels.
Formulas that pair Peg-70 Mango Glycerides with heavy oils or waxes could still pose a clogging risk, so always consider the whole ingredient list rather than this single component in isolation.
Summary
Peg-70 Mango Glycerides is a plant-derived cleansing and emulsifying agent. Its polyethylene glycol side chains attract water while the glyceride portion grabs onto oils, allowing it to lift away dirt and makeup or hold water and oil phases together in a stable mixture. This dual action lets brands simplify formulas by using one ingredient for two key jobs.
Although not the most famous surfactant on the market, it has a steady following among formulators who want a mild, upcycled and vegan alternative to traditional PEG esters. You will mostly see it in gentle facial cleansers, micellar waters and light lotions rather than mass-market shampoos or bar soaps.
Safety testing and decades of cosmetic use show Peg-70 Mango Glycerides to be low risk for irritation or sensitization when used correctly. As with any new skincare ingredient it is smart to perform a small patch test first to make sure your skin agrees with it.
