Ingredient review
PEG-6 Butylene Glycol Laurate
INCI: PEG-6 Butylene Glycol Laurate
A gentle synthetic emulsifier that helps mix water and oil in your products, but may not suit those avoiding PEGs.
In plain English
PEG-6 Butylene Glycol Laurate is a man-made ingredient that helps water and oil stay blended together in creams, lotions, and cleansers. Without emulsifiers like this, your product would separate into an oily layer and a watery layer. It also has mild cleansing properties, so it can help remove dirt and makeup without being harsh. The 'PEG' part means it's made with polyethylene glycol, which some people prefer to avoid due to concerns about impurities, though cosmetic-grade versions are purified.

Quick decision guide
Useful, but context matters
PEG-6 Butylene Glycol 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.
- Step 1Start with the score, then check the irritation and clogging risk before judging PEG-6 Butylene Glycol Laurate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic emulsifier created by reacting lauric acid (from coconut or palm oil) with butylene glycol and polyethylene glycol (PEG). It belongs to a class of ingredients that reduce surface tension between oil and water.
How it works
It has both water-loving (hydrophilic) and oil-loving (lipophilic) parts. When you apply a product containing this ingredient, it helps spread the formula evenly on your skin, allowing both water-soluble and oil-soluble ingredients to be delivered together. In cleansers, it helps lift and rinse away oily impurities.
Pros
Gentle on skin
Has a low irritation risk, making it suitable for most skin types, including sensitive skin, when used at typical concentrations.
Effective emulsifier
Creates stable, smooth creams and lotions that don't separate, ensuring you get a consistent dose of ingredients every time you use the product.
Cons and cautions
Potential impurities
As a PEG compound, it may contain trace amounts of ethylene oxide or 1,4-dioxane if not properly purified, though cosmetic-grade versions are refined to safe levels.
Not eco-friendly
It is synthetic and not readily biodegradable, which may be a concern for environmentally conscious consumers.
Best for
- People with normal to combination skin
- Those who use lotions, creams, or makeup removers and want a stable texture
Use caution if
- Individuals who strictly avoid PEGs or synthetic emulsifiers
- Those with known sensitivity to PEG compounds (rare)
Usage tips
Safety summary
PEG-6 Butylene Glycol Laurate is considered safe for cosmetic use at typical concentrations. The main concern is potential trace impurities from manufacturing, but cosmetic-grade ingredients are purified to meet safety standards. Irritation and allergy are rare.
Research notes
The Cosmetic Ingredient Review (CIR) panel reviewed PEG compounds and found them safe as used. No specific studies on this exact ingredient were found, but its chemical class is well-studied and considered low-risk.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU, and many other regions. The CIR panel has deemed it safe as used in rinse-off and leave-on products.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- Synthetic and not readily biodegradable. Sourcing of lauric acid may involve palm oil, so look for sustainably sourced versions if that matters to you.
Good to know
- PEG-6 Butylene Glycol Laurate is considered safe by the Cosmetic Ingredient Review (CIR) panel at concentrations up to 25%.
- It is often used in combination with other emulsifiers to improve formula stability.
