Ingredient review
Butylene Glycol Laurate
INCI: Butylene Glycol Laurate
A gentle, lightweight emollient that helps soften skin and improve product texture without clogging pores.
In plain English
Butylene Glycol Laurate is a synthetic ingredient made from butylene glycol and lauric acid (a fatty acid found in coconut oil). In skincare, it acts as an emollient, meaning it helps soften and smooth the skin by forming a light, non-greasy film that reduces water loss. It also helps other ingredients spread more evenly and gives products a silky feel. Because it's lightweight and low on the comedogenic scale, it's often used in formulations for oily or acne-prone skin.

Quick decision guide
Useful, but context matters
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 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
Butylene Glycol Laurate is an ester created by combining butylene glycol (a humectant and solvent) with lauric acid (a fatty acid from coconut or palm kernel oil). It appears as a clear to slightly yellow liquid and is used primarily for its emollient and skin-conditioning properties.
How it works
When applied to the skin, Butylene Glycol Laurate sits on the surface and fills in the gaps between skin cells, creating a smooth, soft feel. It also helps reduce transepidermal water loss (TEWL) — the amount of water that evaporates from your skin — by forming a thin, breathable barrier. Additionally, it improves the texture and spreadability of products, making them feel less sticky or greasy.
Pros
Lightweight hydration
Provides a soft, smooth feel without heavy greasiness, making it ideal for daytime use and oily skin types.
Low pore-clogging risk
Rated low on the comedogenic scale, so it's less likely to cause breakouts compared to heavier oils or butters.
Cons and cautions
Synthetic origin
Derived from petrochemicals and natural fatty acids, which may not align with preferences for 100% natural or organic products.
Limited independent research
Most safety data comes from industry sources; long-term independent studies on repeated use are sparse.
Best for
- People with oily or combination skin looking for a lightweight moisturizer
- Anyone who wants a non-greasy emollient in their routine
Use caution if
- Those with known allergies to lauric acid or butylene glycol derivatives (rare)
Usage tips
Safety summary
Butylene Glycol Laurate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, and is not known to be toxic or carcinogenic. However, as with any ingredient, individuals with very sensitive skin should patch-test new products.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) and the European Chemicals Agency (ECHA) support its use as a skin-conditioning agent. Most studies focus on acute toxicity and skin irritation, with no significant concerns identified. Long-term human exposure studies are limited.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has reviewed related esters and found them safe as used.
- Common uses
- Moisturizers, Cleansers, Sunscreens, Makeup removers
- Environmental note
- Butylene Glycol Laurate is synthetic and not readily biodegradable in all conditions. Its production involves petrochemicals, which may have a higher environmental footprint than some plant-derived alternatives.
Good to know
- Butylene Glycol Laurate is different from plain butylene glycol — it's an ester, so it acts as an emollient rather than a humectant.
- It's often used in makeup removers because it helps dissolve oil-based impurities without stripping the skin.
