PEG-9 Glyceryl Laurate

INCI: PEG-9 Glyceryl Laurate

A gentle emulsifier that helps mix water and oil, generally well-tolerated and safe for most skin types.

In plain English

PEG-9 Glyceryl Laurate is a helper ingredient that allows water and oil to blend together smoothly in creams, lotions, and cleansers. It is made by attaching a small chain of ethylene oxide (PEG-9) to glyceryl laurate, which comes from glycerin and lauric acid (a fatty acid found in coconut oil). In simple terms, it acts like a bridge between water-loving and oil-loving ingredients, creating a stable, creamy texture. It is considered very mild and is often used in gentle, non-stripping cleansers.

Quick decision guide

Useful, but context matters

PEG-9 Glyceryl 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 PEG-9 Glyceryl 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 compound created by reacting glycerin, lauric acid, and ethylene oxide. It belongs to the PEG (polyethylene glycol) family of emulsifiers and is known for its mildness and compatibility with sensitive skin.

How it works

In a cosmetic formula, PEG-9 Glyceryl Laurate sits at the boundary between oil and water droplets, reducing surface tension so they stay mixed. This prevents separation and gives products a smooth, uniform feel. It also has mild cleansing properties, helping to lift dirt and oil without stripping the skin's natural moisture barrier.

Pros

Very mild on skin

PEG-9 Glyceryl Laurate is known for its low irritation potential, making it a good choice for sensitive skin or daily-use cleansers and moisturizers.

Versatile emulsifier

It works well in both rinse-off and leave-on products, helping to create stable, creamy textures that feel pleasant on the skin.

Cons and cautions

Potential trace impurities

As a PEG compound, it may contain trace amounts of 1,4-dioxane (a possible carcinogen) if not properly purified during manufacturing. Reputable brands ensure purification to safe levels.

Not for PEG-free preferences

If you follow a strict 'PEG-free' or 'ethoxylated-free' routine, this ingredient does not fit that criteria, even though it is generally considered safe.

Best for

  • People with normal to dry skin looking for a gentle, non-irritating emulsifier
  • Anyone using lightweight creams or lotions that need a stable texture

Use caution if

  • Individuals who specifically avoid PEG compounds or ethoxylated ingredients due to personal preference or ethical concerns

Usage tips

Use in formulations at 1–5% for stable emulsions; higher concentrations (up to 10%) are fine for rinse-off cleansers.
Combine with a co-emulsifier like cetearyl alcohol for thicker creams.
Store products containing this ingredient in a cool, dry place to maintain emulsion stability.

Safety summary

PEG-9 Glyceryl Laurate is considered safe for use in cosmetics at typical concentrations. The main safety concern is the potential presence of 1,4-dioxane, but reputable manufacturers purify their ingredients to meet safety standards. Regulatory bodies like the CIR and EU CosIng have approved its use.

Research notes

Research on PEG-9 Glyceryl Laurate specifically is limited, but the broader class of PEG glyceryl esters has been evaluated for safety and mildness. Studies show they have low skin irritation and sensitization potential. The CIR has reviewed PEG compounds and concluded they are safe in cosmetics when formulated to avoid impurities.

Common label clues

Typical concentration
1–5% in leave-on products; up to 10% in rinse-off products
Regulatory status
Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed PEG compounds and found them safe when formulated to minimize impurities.
Common uses
Cleansers, Lotions, Creams, Makeup removers
Environmental note
PEG compounds are generally biodegradable, but their production involves ethylene oxide, which is derived from fossil fuels. Some consumers prefer plant-based alternatives for environmental reasons.

Good to know

  • PEG-9 Glyceryl Laurate is often used in 'micellar water' type cleansers because of its gentle cleansing action.
  • The number '9' refers to the average length of the PEG chain, which affects its water solubility and mildness.
