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 Ppg-6 C12-15 Alketh-12?

PPG-6 C12-15 Alketh-12 is a lab made ingredient that comes from a blend of medium-length fatty alcohols with 12 to 15 carbon atoms. Chemists first react these alcohols with propylene oxide to add six propylene glycol units, then follow with ethylene oxide to attach about twelve ethylene glycol units. The result is a clear to pale yellow liquid that mixes easily with both oil and water based ingredients.

Nonionic surfactants like this one became popular in the 1970s when brands needed gentler and more versatile emulsifiers for leave-on skin care. Because it is made from synthetic fatty alcohols rather than animal or plant fats it offers consistent quality and is less likely to vary from batch to batch.

You will most often spot PPG-6 C12-15 Alketh-12 in moisturizers, lotions, sunscreens, facial masks, liquid foundations, makeup removers, cleansing balms, hair conditioners and rinse-off scrubs. In these products it helps keep oil and water blended so the formula stays smooth from the first pump to the last.

Ppg-6 C12-15 Alketh-12’s Cosmetic Benefits/Uses

This ingredient plays one key role in personal care formulas.

Emulsifying: it binds oil and water together so creams do not separate, textures feel lighter and active ingredients are evenly spread across the skin or hair. A stable emulsion also means a longer shelf life and a more pleasant user experience.

Who Can Use Ppg-6 C12-15 Alketh-12

Ppg-6 C12-15 Alketh-12 is considered gentle enough for most skin types, including oily, combination, dry and even sensitive skin, because it does not clog pores or leave an occlusive film. Very reactive or allergy-prone skin could still encounter issues, though this is uncommon, and there is no specific skin type that should automatically avoid it.

Because the ingredient is made entirely from synthetic fatty alcohols and petrochemical feedstocks, it contains no animal-derived components. That makes it suitable for both vegans and vegetarians who wish to keep animal ingredients out of their routines.

Current safety data show no reproductive or developmental concerns, so products containing this emulsifier are generally viewed as safe for people who are pregnant or breastfeeding. This is not medical advice and anyone who is expecting or nursing should have their doctor review all personal care products to be certain they meet individual needs.

Ppg-6 C12-15 Alketh-12 is not known to cause photosensitivity, so it will not make skin more prone to sunburn. It also plays well with most other cosmetic ingredients, adding no special usage restrictions beyond standard good formulation practice.

Potential Side Effects/Adverse Reactions

Side effects and reactions to topical Ppg-6 C12-15 Alketh-12 vary from person to person. The points below outline potential issues, but most users will not experience them when the ingredient is properly formulated and used as directed.

  • Mild skin irritation such as stinging or redness, especially on very sensitive skin
  • Contact dermatitis in individuals already allergic to similar surfactants
  • Transient eye irritation if the product accidentally gets into the eyes
  • Dryness or tightness when used at high concentrations in rinse-off formulas
  • Enhanced penetration of other actives, which may amplify irritation from those actives

If any discomfort or adverse reaction develops, stop using the product and seek advice from a qualified healthcare professional.

Comedogenic Rating

Rating: 1 out of 5. Ppg-6 C12-15 Alketh-12 has a lightweight, non-occlusive structure that mixes well with water so it is unlikely to build up inside pores or create the waxy plugs that trigger blackheads. It is primarily an emulsifier rather than an oily emollient, which keeps its clogging potential low. This makes it generally suitable for people prone to acne or breakouts. No studies have reported comedogenicity at the levels normally used in cosmetics, though individual responses can always vary.

Summary

Ppg-6 C12-15 Alketh-12 is mainly valued for its emulsifying power, binding oil and water so creams, lotions and cleansers stay smooth and stable. Its balanced chain length and combination of propylene and ethylene glycol units let it sit at the oil-water interface, lowering surface tension and preventing separation throughout a product’s shelf life.

While not a headline ingredient, it enjoys steady use in moisturizers, sunscreens, liquid makeup and cleansing balms because it delivers reliable performance without adding heaviness. Formulators appreciate that it works across a wide pH range and stays gentle on most skin types.

Current safety data show a very low risk of irritation or toxicity when used as directed, making this ingredient safe for everyday cosmetics. As with any new product, it is wise to patch test first to be sure your skin agrees with the complete formula.
