Dimethicone PEG-3 Laurate

INCI: DIMETHICONE PEG-3 LAURATE

A gentle silicone emulsifier that improves texture and stability, but may not suit those avoiding silicones or ethoxylated ingredients.

In plain English

Dimethicone PEG-3 Laurate is a hybrid ingredient that combines silicone (dimethicone) with a modified fatty acid (laurate) and a small PEG chain. It acts as a bridge between water and oil, allowing them to mix smoothly in creams, lotions, and makeup. This gives products a silky, spreadable feel without heavy greasiness. The silicone part helps the product glide on skin and leaves a soft, smooth finish. The PEG part helps the ingredient dissolve in water-based formulas. It is considered very gentle and unlikely to clog pores or cause irritation for most people.

Quick decision guide

Useful, but context matters

Dimethicone PEG-3 Laurate 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-3 Laurate.
  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 emulsifier made by attaching a short polyethylene glycol (PEG) chain and lauric acid (a fatty acid from coconut or palm oil) to dimethicone, a common silicone.

How it works

It reduces the surface tension between water and oil phases in a formula, allowing them to blend into a stable emulsion. This prevents separation and gives the product a uniform, creamy texture. On skin, it leaves a thin, breathable silicone film that feels smooth and non-sticky.

Pros

Silky, non-greasy feel

Leaves a smooth, velvety finish on skin without heavy oiliness, making it ideal for lightweight lotions and sunscreens.

Gentle for most skin types

Rated low for both irritation and comedogenicity, so it is unlikely to cause breakouts or stinging even for sensitive skin.

Cons and cautions

Potential trace contaminant concern

As a PEG derivative, it may contain trace amounts of 1,4-dioxane from manufacturing. Reputable brands purify their ingredients to minimize this, but it is a consideration for the cautious.

Not eco-friendly

Silicone-based ingredients like this one are not biodegradable and can accumulate in the environment, which may be a concern for eco-conscious consumers.

Best for

  • People who enjoy lightweight, silky moisturizers or makeup
  • Those with normal to combination skin looking for a non-greasy finish

Use caution if

  • Individuals strictly avoiding silicones or PEG derivatives

Usage tips

Look for products from brands that test for 1,4-dioxane purity if you are concerned about contaminants.
Use in leave-on products like moisturizers and sunscreens for best texture benefits; rinse-off products may not need this ingredient.

Safety summary

Generally recognized as safe for topical cosmetic use at typical concentrations. The main safety consideration is the potential presence of 1,4-dioxane, a byproduct of ethoxylation. Reputable manufacturers purify the ingredient to reduce this contaminant to trace levels. Overall irritation and allergy risk is very low.

Research notes

Limited direct clinical studies on this specific ingredient, but its components (dimethicone, PEGs, lauric acid) are well-studied and considered safe in cosmetics. The Cosmetic Ingredient Review (CIR) panel has reviewed related dimethicone copolyols and found them safe as used.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for cosmetic use in the US, EU, and most major markets. The EU has strict limits on 1,4-dioxane content in finished products (≤10 ppm).
Common uses
Moisturizers, Sunscreens, Foundations, Hair conditioners
Environmental note
Silicone derivatives are not biodegradable and may contribute to environmental accumulation. Some regions are exploring restrictions on non-biodegradable silicones.

Good to know

  • The 'PEG-3' indicates a short polyethylene glycol chain, which helps the ingredient become water-dispersible.
  • This ingredient is often used in combination with other emulsifiers to create stable, elegant formulas.
