INCI: PPG-2 Cocamine

A mild surfactant that helps cleanse and condition, but may cause irritation for sensitive skin at higher concentrations.

In plain English

PPG-2 Cocamine is a cleansing and conditioning ingredient made from coconut oil and a synthetic compound called propylene glycol. It helps water mix with oil so that dirt and makeup can be rinsed away, and it also reduces static in hair. While it is generally considered safe, it can be mildly irritating to very sensitive skin or if used in high amounts.

Quick decision guide

Useful, but context matters

PPG-2 Cocamine can be useful, but watch for some irritation potential.

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-2 Cocamine.
  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

moderate

Can bother some users, especially with frequent use, damaged skin, or strong companion ingredients.

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-2 Cocamine is a semi-synthetic surfactant (cleansing agent) created by reacting coconut-derived fatty amines with propylene glycol. It belongs to a class of ingredients called alkoxylated amines, which are known for their ability to reduce surface tension and provide conditioning properties.

How it works

In a cosmetic product, PPG-2 Cocamine works by lowering the surface tension between water and oil, allowing them to mix. This helps lift dirt, oil, and makeup from the skin or hair so they can be washed away. It also has antistatic properties, meaning it helps reduce frizz and flyaways in hair by neutralizing electrical charges.

Pros

Effective cleanser

Helps remove excess oil, dirt, and makeup without stripping the skin completely when used at typical levels.

Conditioning properties

Provides light conditioning to hair and skin, reducing static and improving feel after washing.

Cons and cautions

Potential irritation

At higher concentrations or for sensitive individuals, it can cause mild stinging, redness, or dryness.

Semi-synthetic origin

While derived partly from coconut, it is chemically modified, which may not appeal to those seeking fully natural ingredients.

Best for

  • People with normal to oily skin looking for effective cleansing
  • Those who want a mild conditioner in their shampoo or body wash

Use caution if

  • Individuals with very sensitive or reactive skin, especially if prone to irritation from surfactants

Usage tips

Look for this ingredient in rinse-off products like shampoos and body washes rather than leave-on products to minimize irritation risk.
If you have sensitive skin, choose products where PPG-2 Cocamine appears near the end of the ingredient list, indicating a lower concentration.

Safety summary

PPG-2 Cocamine is generally safe for use in rinse-off cosmetics at typical concentrations. It has a low comedogenic risk and is not known to be a significant allergen. However, it can cause mild irritation in sensitive individuals, especially at higher levels. Regulatory bodies consider it safe when used as intended.

Research notes

Research on PPG-2 Cocamine is limited, but it is structurally similar to other alkoxylated amines that have been evaluated for skin irritation and sensitization. Studies suggest low acute toxicity and moderate irritation potential at high concentrations. It is not classified as a carcinogen or reproductive toxin.

Common label clues

Typical concentration
Low, typically 0.5% to 3%
Regulatory status
Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific concentration restrictions, though formulators are advised to keep levels low to avoid irritation.
Common uses
Cleansers, Shampoos, Conditioners, Body washes
Environmental note
PPG-2 Cocamine is partially derived from renewable coconut oil and is considered biodegradable, but its synthetic modification means it may not break down as quickly as fully natural alternatives.

Good to know

  • PPG-2 Cocamine is often used alongside other mild surfactants to create a balanced cleansing formula.
  • It is considered biodegradable and generally safe for the environment at typical use levels.
