Dimethicone PEG-8 Olivate
INCI: DIMETHICONE PEG-8 OLIVATE
A gentle silicone emulsifier that helps create smooth, stable formulas without heavy residue.
In plain English
Dimethicone PEG-8 Olivate is a hybrid ingredient that combines silicone (dimethicone) with a modified olive oil derivative. Its main job is to help water and oil mix together in a product, so you get a smooth, creamy texture that doesn't separate. It also leaves a silky, non-greasy feel on the skin, making it popular in moisturizers and sunscreens.

Dimethicone PEG-8 Olivate 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 Dimethicone PEG-8 Olivate.
- 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 created by attaching a polyethylene glycol (PEG) chain to dimethicone (a silicone) and then reacting it with olivate (from olive oil). This gives it both water-loving and oil-loving properties.
How it works
When you apply a product containing this ingredient, it helps spread the formula evenly across the skin. The silicone part provides a smooth, velvety feel, while the olivate portion adds mild conditioning. It also helps stabilize emulsions, so the product stays mixed and effective over time.
Pros
Lightweight feel
Leaves a silky, non-sticky finish that works well under makeup or sunscreen.
Formula stability
Helps prevent separation in creams and lotions, so the product stays effective longer.
Cons and cautions
Silicone content
Some people prefer to avoid silicones due to environmental concerns or personal preference.
PEG concerns
PEG compounds can be contaminated with impurities during manufacturing, though reputable brands use purified grades.
Best for
- Anyone looking for a lightweight, non-greasy moisturizer
- People who want stable, well-mixed skincare products
Use caution if
- Those who strictly avoid silicones or PEG compounds
- Very sensitive skin that reacts to many emulsifiers
Usage tips
Safety summary
Generally recognized as safe for topical use in cosmetics. Low irritation and comedogenic risk. Some consumers may choose to avoid PEGs or silicones for personal reasons.
Research notes
Limited direct studies on this specific ingredient, but the safety of dimethicone copolyols and PEG derivatives is well-documented by cosmetic safety panels. No significant toxicity or irritation concerns at typical concentrations.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar dimethicone PEG compounds and found them safe at current usage levels.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup removers
- Environmental note
- Silicones can be slow to biodegrade. PEG-8 Olivate is a modified silicone, but its environmental impact is less studied than simpler silicones.
Good to know
- This ingredient is often used in 'silicone-free' claims? Actually, it does contain silicone, so check labels carefully.
- It is considered safe by major cosmetic safety panels at typical use levels.
