What Is Ppg-5 C12-14 Sec-Pareth-9?
Ppg-5 C12-14 Sec-Pareth-9 is a synthetic, nonionic surfactant created by attaching five units of propylene oxide and nine units of ethylene oxide to secondary fatty alcohols that contain 12 to 14 carbon atoms. The fatty alcohols typically come from plant oils such as coconut or palm, though fully synthetic sources can also be used. First introduced in the late twentieth century as the demand grew for milder, sulfate-free cleansers, it quickly became popular with formulators because it offers effective cleansing without the harshness often linked to traditional sulfates.
Production starts with the chosen C12-14 secondary alcohol. This alcohol is first reacted with propylene oxide, then with ethylene oxide, in a controlled process called alkoxylation. The result is a molecule with both oil-loving and water-loving portions, which lets it interact with oils and water at the same time. This dual nature is what gives the ingredient its cleansing and emulsifying power.
You will most often see Ppg-5 C12-14 Sec-Pareth-9 in rinse-off products where gentle but thorough cleansing is needed. Typical formulas include shampoos, body washes, facial cleansers, micellar waters, makeup removers and bath foams. It can also appear in lotions, sunscreens and light creams where keeping oily and watery ingredients evenly mixed is important.
Ppg-5 C12-14 Sec-Pareth-9’s Cosmetic Benefits/Uses
In skin and hair care formulas this ingredient serves two main roles that enhance both product performance and user experience:
- Cleansing: The surfactant lowers the surface tension between skin or hair and the oils, dirt and pollutants sitting on them. It lifts away grime so it can be rinsed off easily, leaving a fresh feel without heavy residue or tightness
- Emulsifying: It helps keep oil-based and water-based ingredients blended together, preventing separation in the bottle and ensuring the active ingredients are delivered evenly with every use
Who Can Use Ppg-5 C12-14 Sec-Pareth-9
This ingredient is generally well tolerated by most skin types. Normal, oily and combination skin usually benefit from its effective yet mild cleansing action. Dry or sensitive skin can also use it, though people with very reactive skin should pay attention to how their skin feels after use because any surfactant can potentially cause tightness if left on too long or used in high concentrations.
Ppg-5 C12-14 Sec-Pareth-9 is synthesized from plant oils or fully synthetic sources and contains no animal-derived components, making it suitable for vegans and vegetarians. Always check the full ingredient list of a finished product to be sure other animal ingredients are not present.
Current safety data indicate no specific risks for pregnant or breastfeeding women when the ingredient is used topically in rinse-off or leave-on cosmetics. However this is not medical advice; anyone who is pregnant or nursing should review their skincare routine with a qualified healthcare professional to be extra safe.
The molecule does not absorb UV light or make skin more vulnerable to the sun, so it is not associated with photosensitivity. It is also non comedogenic and unlikely to clog pores in most formulations.
Potential Side Effects/Adverse Reactions
Side effects from topical use of Ppg-5 C12-14 Sec-Pareth-9 vary from person to person. The points below describe potential, not guaranteed, reactions. When formulated correctly most users experience none of these issues.
- Skin irritation – a temporary feeling of burning, stinging or discomfort, more common on very sensitive skin
- Dryness or tightness – possible if used in a high-foaming cleanser or washed off with very hot water
- Redness or mild inflammation – usually short lived and often linked to over-cleansing
- Allergic contact dermatitis – rare cases of rash or itching in individuals allergic to ethoxylated surfactants
- Eye stinging – may occur if the product accidentally gets into the eyes before rinsing
If you experience any negative reaction stop using the product and consult a dermatologist or healthcare professional for guidance.
Comedogenic Rating
Rating: 0/5
Ppg-5 C12-14 Sec-Pareth-9 is a highly water-soluble, nonionic surfactant that easily rinses off the skin. Because it does not leave an oily film and has no fatty acid backbone that lingers in pores, it is considered non-comedogenic. This makes it suitable for people prone to acne or breakouts. If a final product containing this surfactant feels heavy or greasy, the pore-clogging risk usually comes from other ingredients rather than from Ppg-5 C12-14 Sec-Pareth-9 itself.
Summary
Ppg-5 C12-14 Sec-Pareth-9 acts mainly as a cleanser and emulsifier. Its molecular structure carries both water-loving and oil-loving parts, so it lifts away dirt and oil while helping water and oil ingredients stay mixed in a stable formula. This dual action lets products foam well, rinse clean and remain uniform on the shelf.
While not as famous as sulfates or newer trendy surfactants, it has carved out a steady spot in shampoos, body washes and gentle facial cleansers thanks to its balanced cleansing strength and mildness.
Current safety data show a low risk of irritation or allergic response when used at typical cosmetic levels. Still, skin can react differently from person to person, so it is always smart to patch test any new product that contains Ppg-5 C12-14 Sec-Pareth-9 before full use.
