What Is Peg-60?
Peg-60 is a synthetic ingredient made by reacting ethylene oxide with water to create long chains of polyethylene glycol, averaging 60 repeating units. This process turns the raw materials into a clear, water-soluble substance that blends easily with both water and oil. The family of polyethylene glycols has been around since the 1940s and quickly found a place in personal care because of its ability to dissolve ingredients that normally separate. Peg-60 is produced in controlled factory settings where temperature and pressure guide the reaction, followed by purification that removes unused reactants. You will spot Peg-60 in face washes, hydrating toners, sheet masks, lightweight lotions, leave-on conditioners, anti-aging serums and after-sun gels where a smooth, non-greasy feel is needed.
Peg-60’s Cosmetic Benefits/Uses
Formulators add Peg-60 to products for two key reasons:
- Humectant – draws water from the air and holds it on the skin surface, helping products deliver a quick hit of moisture and keeping formulas from drying out in the jar
- Solvent – dissolves fragrances, plant extracts and other active ingredients so they stay evenly distributed, which means every pump or dab gives the same level of performance
Who Can Use Peg-60
Peg-60 is generally well tolerated by most skin types including oily, dry, combination and sensitive because its molecules sit on the surface rather than penetrating deeply. People with severely compromised or freshly exfoliated skin may experience a light tingle since the ingredient can pull extra water into the upper layers, so if your barrier is already inflamed you may want to introduce it slowly.
The ingredient is synthesized from petroleum- or plant-derived feedstocks and contains no animal material, making it suitable for both vegans and vegetarians.
Current safety data show no specific risks for pregnant or breastfeeding women when Peg-60 is used topically and in the small amounts found in cosmetics. Absorption through intact skin is minimal, yet this is not medical advice and anyone who is pregnant or nursing should confirm product choices with a qualified healthcare professional.
Peg-60 does not increase photosensitivity so products containing it can be used during the day as well as at night without raising the risk of sunburn. It also plays nicely with common actives such as retinol, vitamin C and niacinamide because it mainly acts as a carrier and water binder rather than an active treatment on its own.
Potential Side Effects/Adverse Reactions
Reactions to topical Peg-60 differ from person to person. The effects listed below are possible but uncommon when the ingredient is used at the low concentrations typical of finished cosmetics and when the formula has been properly balanced by the manufacturer.
- Mild skin irritation or redness especially on compromised or highly sensitive skin
- Stinging upon application if applied to freshly shaved, exfoliated or broken skin
- Contact dermatitis in rare cases where an individual has a specific polyethylene glycol allergy
- Enhanced penetration of other actives which might amplify their own irritant potential
- Eye irritation when wash-off products accidentally get into the eyes
If any of these effects occur stop using the product and consult a healthcare professional to determine the best course of action.
Comedogenic Rating
Rating: 0 (non-comedogenic). Peg-60 is highly water soluble and rinses clean without leaving a greasy film that could block pores. Its large hydrophilic chains sit on the surface then wash away, so it does not trap dead cells or sebum. Because of this it is generally suitable for people prone to acne or breakouts. Keep in mind the overall formula matters too; Peg-60 added to a rich cream with heavy oils can still feel occlusive even though the ingredient itself is not pore-clogging.
Summary
Peg-60 works as a humectant that attracts water to the skin and as a solvent that keeps fragrances, extracts and actives evenly dispersed. It does this through its long polyethylene glycol chains which love water and can bridge water with small amounts of oil. The ingredient is a quiet workhorse rather than a trend star, yet it shows up in everything from cleansers to serums because it solves the practical problems of mixing and moisture retention.
Current research finds Peg-60 safe for topical use at the levels used in cosmetics, with irritation or allergy being rare. As with any new product it is wise to patch test first so you can spot personal sensitivities before applying it over larger areas.
