Ingredient review
Butyloctyl Palmitate
INCI: Butyloctyl Palmitate
A lightweight, non-greasy emollient that spreads easily and is generally well-tolerated, making it a common choice for moisturizers and sunscreens.
In plain English
Butyloctyl Palmitate is a synthetic oil-like ingredient that feels light and silky on the skin, not heavy or sticky. It helps moisturizers and sunscreens spread smoothly and leaves a soft, non-greasy finish. It is often used as a substitute for natural oils because it is stable and less likely to cause breakouts.

Quick decision guide
Useful, but context matters
Butyloctyl Palmitate 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 Butyloctyl Palmitate.
- 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 ester made from palmitic acid (a fatty acid found in palm oil) and butyloctanol (a branched-chain alcohol). It is a clear, odorless liquid that mimics the feel of natural oils.
How it works
It sits on the skin's surface to reduce water loss (like a gentle barrier) and fills in tiny gaps between skin cells, making the skin feel smoother. It also helps other ingredients spread evenly and gives products a luxurious, silky texture.
Pros
Lightweight feel
Unlike heavy oils, butyloctyl palmitate absorbs quickly and leaves no sticky residue, making it ideal for daytime moisturizers and sunscreens.
Improves product texture
It helps creams and lotions spread evenly and smoothly, so you need less product to cover your face, and makeup applies more evenly on top.
Cons and cautions
Synthetic origin
It is made in a lab, which may be a drawback if you prefer only plant-derived ingredients. However, it is still considered safe and gentle.
Potential for mild irritation
Although rare, some people with extremely sensitive or eczema-prone skin may experience slight stinging or redness. Patch testing is recommended.
Best for
- People with normal to dry skin looking for a lightweight moisturizer
- Anyone who wants a non-greasy sunscreen or makeup base
Use caution if
- Those with a known allergy to synthetic esters (very rare)
Usage tips
Safety summary
Butyloctyl Palmitate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential. The Cosmetic Ingredient Review (CIR) panel has reviewed similar esters and found them safe. No significant health concerns have been reported.
Research notes
Research on butyloctyl palmitate is limited, but it is structurally similar to other well-studied esters like isopropyl palmitate. Studies show it is non-irritating and non-sensitizing in human patch tests. It is widely used in sunscreens to improve texture and SPF distribution.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics by the FDA (as part of the Generally Recognized as Safe list for indirect food contact) and by the European Commission (Annex V). No concentration restrictions in leave-on or rinse-off products.
- Common uses
- Moisturizers, Sunscreens, Makeup, Hair conditioners
- Environmental note
- Synthesized from palm-derived palmitic acid, so its environmental impact depends on sustainable palm sourcing. It is biodegradable and not bioaccumulative.
Good to know
- Butyloctyl Palmitate is often used as a replacement for silicone oils in 'silicone-free' formulations.
- It is biodegradable and not considered a marine pollutant.
