We verify all information on this page using publicly available nomenclature standards from The Personal Care Products Council (PCPC), the European Commission's CosIng database and documentation provided directly by ingredient manufacturers. Our analysis is based on technical data from these sources to ensure accuracy and reliability.

What Is Peg/Ppg-14/7 Dimethyl Ether?

Peg/Ppg-14/7 Dimethyl Ether is a synthetic polyether created by reacting ethylene oxide and propylene oxide with a dimethyl ether backbone, giving an average chain of 14 ethylene oxide units and 7 propylene oxide units. The raw materials come from petroleum or bio-based feedstocks that are refined into ethylene and propylene gases, then polymerized under carefully controlled temperatures and pressures. Chemists began exploring these polyethers for personal care in the mid-20th century, and by the 1980s their mildness and versatility made them common in skin care labs worldwide. Today you will spot Peg/Ppg-14/7 Dimethyl Ether in lightweight moisturizers, sheet masks, anti-aging serums, facial mists, makeup primers, sunscreens, hair conditioners and aftershave lotions where a silky skin feel and balanced hydration are desired.

Peg/Ppg-14/7 Dimethyl Ether’s Cosmetic Benefits/Uses

This ingredient is prized as a skin-conditioning agent. It forms a flexible, breathable layer that smooths rough spots, softens the skin surface and helps other active ingredients spread evenly. Because it is water-soluble it rinses clean without a greasy residue, leaving skin feeling fresh and comfortably hydrated.

Who Can Use Peg/Ppg-14/7 Dimethyl Ether

This lightweight polyether suits most skin types including dry, normal, combination and oily skin because it hydrates without leaving an oily film. Sensitive skin usually tolerates it as well thanks to its mild nature, though anyone with a known polyethylene glycol allergy should avoid it.

The ingredient is synthetically produced from petrochemical or plant-derived feedstocks and contains no animal matter so it is appropriate for vegans and vegetarians.

Current safety assessments show no specific risks for pregnant or breastfeeding women when the ingredient is used topically in cosmetic concentrations. Still this is not medical advice and anyone who is expecting or nursing should discuss all skincare choices with a qualified healthcare provider to be safe.

Peg/Ppg-14/7 Dimethyl Ether does not make skin more sensitive to sunlight and it plays well with common actives such as vitamin C, niacinamide and retinoids.

Potential Side Effects/Adverse Reactions

Side effects from topical Peg/Ppg-14/7 Dimethyl Ether differ from person to person. The points below outline potential reactions but most users will not experience these as long as the ingredient is formulated correctly and used as intended.

  • Mild skin redness or irritation in very sensitive individuals
  • Transient stinging when applied to broken or compromised skin
  • Allergic contact dermatitis in those with polyethylene glycol sensitivities
  • Eye irritation if the product accidentally gets into the eyes

If any of these reactions occur discontinue use and consult a healthcare professional.

Comedogenic Rating

Rating: 0 / 5 (non-comedogenic)

Peg/Ppg-14/7 Dimethyl Ether dissolves fully in water and does not leave an occlusive oily film on the skin. Because it rinses away easily and has a light molecular weight it is unlikely to clog pores or trap sebum. Formulators often choose it for products aimed at a fresh, weightless feel which further reduces the risk of pore blockage.

People who are prone to acne or frequent breakouts can generally use products containing this ingredient without added concern.

Its comedogenic profile can change if blended with heavy oils or waxes so the overall formula still matters.

Summary

Peg/Ppg-14/7 Dimethyl Ether is mainly a skin-conditioning agent that smooths, softens and hydrates by forming a light breathable layer that pulls in water yet rinses clean. Its flexible polymer chain lets active ingredients spread evenly so formulas feel silky instead of greasy.

While it is not a beauty buzzword like hyaluronic acid it has steady popularity among chemists who need an unfussy ingredient that delivers comfort and slip without heaviness. You will find it tucked into many moisturizers, mists and serums even if it rarely gets star billing on the label.

Current safety data show low irritation potential, rare allergy reports and no links to serious health issues when used in normal cosmetic amounts. As with any new product it is wise to do a quick patch test to make sure your skin plays nicely before applying it to larger areas.
