INCI: DIMETHICONE PEG-8 AVOCADOATE

A hybrid silicone-and-avocado emollient that smooths skin and improves product feel without heavy greasiness.

beautyskincareemollient

In plain English

This ingredient is a silicone molecule that has been chemically linked to a piece of avocado oil. It spreads easily on skin, leaving a silky, non-greasy feel. It helps other ingredients glide on and can make skin feel soft and smooth. Because it's silicone-based, it's lightweight and unlikely to clog pores.

Quick decision guide

Useful, but context matters

Dimethicone PEG-8 Avocadoate 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 Dimethicone PEG-8 Avocadoate.
  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 semi-synthetic compound created by attaching avocado oil fatty acids to a silicone chain (dimethicone) via a PEG (polyethylene glycol) bridge. This gives it both water-friendly and oil-friendly properties.

How it works

It forms a thin, breathable film on the skin's surface that reduces water loss and provides a smooth, velvety feel. The avocado oil portion adds a touch of nourishment, while the silicone part ensures even spread and a non-tacky finish.

Pros

Silky, non-greasy feel

Creates a smooth, velvety finish that doesn't feel heavy or sticky, making it ideal for daytime use and under makeup.

Low irritation and comedogenic risk

Unlikely to cause breakouts or irritation, even for sensitive or acne-prone skin types.

Cons and cautions

Synthetic origin

Derived from silicones and PEG, which may not appeal to those seeking fully natural or biodegradable ingredients.

Potential processing impurities

PEG compounds can contain trace levels of ethylene oxide or 1,4-dioxane if not properly purified, though reputable brands ensure high-quality sourcing.

Best for

  • People with normal to oily skin who want a lightweight moisturizer
  • Anyone looking for a primer-like finish under makeup

Use caution if

  • Those who strictly avoid silicones or PEG compounds
  • Individuals with very dry skin may need a richer emollient

Usage tips

Use in moisturizers or primers for a smooth base before makeup.
Layer with water-based serums first for best absorption.
Avoid using with very heavy oils if you have oily skin.

Safety summary

Considered safe for use in cosmetics at typical concentrations. Low irritation and comedogenic risk. As with all PEG compounds, quality control is important to avoid impurities.

Research notes

Limited peer-reviewed studies specifically on this hybrid ingredient, but its components (dimethicone, avocado oil, PEG) are well-studied and recognized as safe by cosmetic safety panels.

Common label clues

Typical concentration
1% to 10%
Regulatory status
Approved for use in cosmetics globally, including by the FDA (U.S.) and EU CosIng database. Manufacturers must ensure PEG compounds are free from harmful impurities.
Common uses
Moisturizers, Serums, Primers, Foundations, Sunscreens
Environmental note
Silicones are generally not biodegradable and can accumulate in the environment. However, this ingredient is used in small amounts and is often rinsed off.

Good to know

  • PEG-8 indicates the polyethylene glycol chain length, which affects water solubility.
  • Avocadoate refers to the avocado oil fatty acids attached to the silicone.
