Polyglyceryl-6 Octacaprylate
INCI: POLYGLYCERYL-6 OCTACAPRYLATE
A gentle, plant-derived emulsifier that helps create stable, lightweight textures with low irritation potential.
In plain English
Polyglyceryl-6 Octacaprylate is a mild ingredient made from plant-based glycerin and fatty acids. Its main job is to help oil and water mix together in products like lotions and creams, so they feel smooth and don't separate. It also leaves a soft, non-greasy feel on the skin.

Quick decision guide
Easy yes for most routines
Polyglyceryl-6 Octacaprylate 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 Polyglyceryl-6 Octacaprylate.
- 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 semi-synthetic emulsifier derived from glycerin (often from plant oils) and caprylic acid (a fatty acid from coconut or palm oil). It belongs to the polyglyceryl ester family, known for being gentle and biodegradable.
How it works
It reduces the surface tension between oil and water, allowing them to form a stable, uniform mixture. This creates a smooth, creamy texture in products and helps other ingredients spread evenly on the skin.
Pros
Gentle on skin
Polyglyceryl-6 Octacaprylate has a low irritation risk and is well-tolerated even by sensitive skin types, making it a safe choice for daily-use products.
Lightweight feel
It creates emulsions that absorb quickly without leaving a heavy or sticky residue, which is ideal for daytime moisturizers and serums.
Cons and cautions
Not for rich textures
If you prefer a thick, heavy cream for very dry skin, this emulsifier alone may not provide the occlusive feel you need; it works best in lightweight formulas.
Potential palm oil sourcing
Caprylic acid is often derived from palm or coconut oil. Without sustainable sourcing, palm oil production can have environmental impacts, so check brand transparency.
Best for
- People with normal to oily or combination skin
- Those who prefer lightweight, non-greasy moisturizers
- Individuals with sensitive skin looking for a gentle emulsifier
Use caution if
- Those with a known allergy to polyglyceryl esters (rare)
- People seeking a very rich, occlusive texture (this is lightweight)
Usage tips
Safety summary
Polyglyceryl-6 Octacaprylate is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, and no significant safety concerns have been reported in regulatory reviews.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found polyglyceryl esters to be safe as used in cosmetics. Studies indicate they are mild and well-tolerated, with low potential for skin sensitization.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific concentration restrictions are common, but typical use is under 5%.
- Common uses
- Moisturizers, Cleansers, Serums, Sunscreens
- Environmental note
- Derived from renewable plant sources, but the sustainability depends on the origin of the caprylic acid (palm vs. coconut). Look for RSPO-certified palm or coconut-derived versions.
Good to know
- Polyglyceryl esters are considered biodegradable and are often used in 'green' or eco-friendly formulations.
- This ingredient is not a preservative; products still need a proper preservation system.
