Ingredient review

PPG-70 Bis-(2-Aminopropyl) Ether

INCI: PPG-70 BIS-(2-AMINOPROPYL) ETHER

A gentle synthetic polymer that helps hair feel smooth and products spread evenly, but offers no active skincare benefits.

beautyskincarehaircare

In plain English

This is a man-made ingredient that forms a thin, flexible film on hair or skin. It helps conditioners and styling products glide on easily and leaves hair feeling soft and less frizzy. Think of it like a lightweight, invisible glove that smooths the surface without clogging pores or causing irritation for most people.

Quick decision guide

Useful, but context matters

PPG-70 Bis-(2-Aminopropyl) Ether 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-70 Bis-(2-Aminopropyl) Ether.
  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

A synthetic polymer derived from polypropylene glycol, modified with amine groups to improve its ability to bind to hair and skin surfaces.

How it works

It deposits a thin, flexible film on the hair shaft or skin surface, reducing friction and static, improving slip during application, and providing a smooth, conditioned feel without heavy buildup.

Pros

Gentle on skin and scalp

Has a low irritation and comedogenic risk, making it suitable for sensitive skin and frequent use.

Improves product feel

Enhances the slip and spreadability of creams and conditioners, making application smoother and more pleasant.

Cons and cautions

Synthetic origin

Derived from petrochemicals, which may not align with clean or natural beauty preferences.

Temporary effect only

Provides surface conditioning without repairing damaged hair or skin; benefits wash away with the next cleanse.

Best for

  • Anyone looking for smoother, less frizzy hair
  • People with normal to dry hair who want extra slip in conditioners

Use caution if

  • Those seeking natural or plant-based ingredients exclusively
  • Individuals with very fine hair who may find film-forming polymers weigh hair down

Usage tips

Use in rinse-off conditioners for best slip and detangling without buildup.
Pair with humectants like glycerin in leave-in products to balance film-forming with hydration.

Safety summary

Considered safe for use in cosmetics at typical concentrations. Low irritation and comedogenic potential. No significant safety concerns reported in regulatory reviews.

Research notes

Limited peer-reviewed studies specific to this ingredient, but it is structurally similar to other PPG-based polymers that have been evaluated as safe by cosmetic ingredient review panels.

Common label clues

Typical concentration
0.1% to 2%
Regulatory status
Approved for use in cosmetics in the EU, US, and other major markets; no known restrictions at typical use levels.
Common uses
Hair conditioners, Leave-in treatments, Styling products, Skin creams
Environmental note
As a synthetic polymer, it is not biodegradable and may accumulate in the environment; however, its low use concentration reduces overall impact.

Good to know

  • The 'PPG-70' indicates a polymer chain length of about 70 propylene glycol units, which affects its film-forming properties.
  • This ingredient is often used in combination with cationic surfactants to boost conditioning performance.
