In plain English

PPG-14 Deceth-6 is a man-made ingredient that helps oil and water blend together in products like cleansers and shampoos. It's a type of surfactant, which means it can help lift dirt and makeup from your skin so they rinse away easily. Because it's designed to be mild, it's less likely to cause irritation or dryness compared to harsher cleansers.

Quick decision guide

Useful, but context matters

PPG-14 Deceth-6 is generally a lower-concern ingredient when the full formula suits your skin.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging PPG-14 Deceth-6.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

PPG-14 Deceth-6 is a synthetic polymer made from propylene glycol and cetyl alcohol. It belongs to a class of ingredients called alkyl ethers, which are known for their ability to act as emulsifiers and surfactants in cosmetic formulations.

How it works

In a product, PPG-14 Deceth-6 sits at the boundary between oil and water molecules. When you apply a cleanser containing it, it helps break down oils, sebum, and waterproof makeup into tiny droplets that can be rinsed away with water. This makes cleansing more effective without requiring harsh scrubbing.

Pros

Effective makeup remover

PPG-14 Deceth-6 helps break down waterproof makeup and sunscreen, making cleansing more thorough without extra rubbing.

Low irritation potential

Compared to traditional sulfates, this surfactant is considered mild and less likely to cause stinging or redness.

Cons and cautions

Synthetic origin

It is a lab-created ingredient, which may not align with preferences for naturally derived or 'clean' beauty products.

Potential for dryness

In high concentrations or in products without enough moisturizing ingredients, it can still strip natural oils from the skin.

Best for

  • People who wear makeup or sunscreen daily
  • Those with normal to combination skin looking for a gentle cleanser

Use caution if

  • Individuals with very dry or compromised skin barriers who prefer oil-based cleansing

Usage tips

Look for this ingredient in rinse-off products like cleansers and shampoos rather than leave-on formulas.
Pair with a moisturizer after cleansing to maintain skin hydration.

Safety summary

PPG-14 Deceth-6 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. However, those with extremely sensitive or dry skin should monitor their reaction.

Research notes

Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found alkyl ethers like PPG-14 Deceth-6 to be safe in rinse-off products. Limited peer-reviewed studies focus specifically on this ingredient, but its chemical class is well-studied.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics in the US, EU, and many other regions. Generally recognized as safe when used as directed.
Common uses
Cleansers, Shampoos, Body washes, Makeup removers
Environmental note
As a synthetic polymer, its biodegradability varies. Some studies suggest it may persist in water systems, but it is not classified as a major environmental concern.

Good to know

  • PPG-14 Deceth-6 is often used alongside other mild surfactants to create a balanced cleansing formula.
  • It is not known to be comedogenic, so it's unlikely to clog pores.
