In plain English

PPG-1 Trideceth-6 is a man-made ingredient that helps oil and water mix together in products like cleansers and lotions. It's a type of surfactant, which means it can also help lift dirt and oil 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 cleansing agents.

Quick decision guide

Useful, but context matters

PPG-1 Trideceth-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-1 Trideceth-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-1 Trideceth-6 is a synthetic compound belonging to the alkyl ether sulfate family. It is created by reacting tridecyl alcohol with ethylene oxide and propylene oxide, resulting in a molecule that has both water-loving and oil-loving parts. This dual nature makes it an effective emulsifier and mild surfactant.

How it works

In a cosmetic product, PPG-1 Trideceth-6 positions itself at the boundary between oil and water droplets, reducing surface tension so they can mix into a stable emulsion. As a surfactant, it also surrounds dirt and oil particles on the skin, allowing them to be rinsed away with water. Its structure is designed to be gentle, so it cleans without overly stripping the skin's natural moisture barrier.

Pros

Mild on skin

PPG-1 Trideceth-6 is designed to be a gentle surfactant, making it suitable for daily cleansers and body washes that won't leave skin feeling tight or dry.

Effective emulsifier

It helps create stable mixtures of oil and water, which improves the texture and consistency of lotions, creams, and makeup removers.

Cons and cautions

Synthetic origin

As a lab-created ingredient, it may not appeal to consumers seeking natural or plant-based alternatives.

Potential for mild irritation

Although generally mild, very high concentrations or prolonged use could cause slight irritation for those with very sensitive or compromised skin.

Best for

  • People looking for gentle, non-stripping cleansers
  • Those with normal to combination skin who want effective but mild cleansing

Use caution if

  • Individuals with known sensitivity to ethoxylated ingredients (rare)

Usage tips

Use in rinse-off products like cleansers and shampoos for best results; leave-on products may require lower concentrations.
Pair with other mild surfactants to create a balanced cleansing formula that maintains skin comfort.

Safety summary

PPG-1 Trideceth-6 is considered safe for use in cosmetics at typical concentrations. It is a mild surfactant with low irritation and comedogenic potential. As with any ingredient, individuals with very sensitive skin should patch test new products.

Research notes

Safety assessments by industry panels and regulatory bodies support the use of PPG-1 Trideceth-6 in cosmetics. It is not associated with significant toxicity or sensitization at intended use levels. Research focuses on its function as a mild surfactant rather than active skin benefits.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. No specific restrictions at typical concentrations.
Common uses
Cleansers, Shampoos, Body washes, Makeup removers, Lotions
Environmental note
PPG-1 Trideceth-6 is synthetic but generally considered biodegradable. Its environmental impact is low when used in rinse-off products at standard concentrations.

Good to know

  • PPG-1 Trideceth-6 is often used in combination with other surfactants to fine-tune foam and cleansing properties.
  • It is considered biodegradable and safe for aquatic environments at typical use levels.
