Ingredient review
Lauryl Dimethicone PEG-10 Phosphate
INCI: LAURYL DIMETHICONE PEG-10 PHOSPHATE
A gentle silicone emulsifier that helps products spread smoothly and rinse off cleanly, with low irritation potential.
In plain English
This ingredient is a hybrid of silicone and a mild soap-like molecule. It helps water and oil mix together in a formula, so your cleanser or moisturizer feels silky and rinses off without leaving a greasy film. Because it's silicone-based, it also gives a smooth, non-sticky feel on skin.

Quick decision guide
Useful, but context matters
Lauryl Dimethicone PEG-10 Phosphate 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 Lauryl Dimethicone PEG-10 Phosphate.
- 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 silicone polymer modified with polyethylene glycol (PEG) and a phosphate group. It acts as an emulsifier and surfactant, meaning it helps blend oil and water phases in cosmetic products and can also help cleanse the skin.
How it works
The silicone portion provides a silky, spreadable texture, while the PEG and phosphate parts allow it to interact with both water and oil. This dual nature lets it stabilize emulsions (like lotions and creams) and help rinse away dirt and makeup without stripping the skin's natural moisture barrier.
Pros
Gentle on skin
Unlike harsh soaps, this silicone-based surfactant cleanses without stripping natural oils, making it suitable for sensitive or dry skin.
Silky texture
It gives products a smooth, non-tacky feel that glides on easily, improving the user experience of creams and sunscreens.
Cons and cautions
Not biodegradable
As a silicone derivative, it may persist in the environment longer than plant-based alternatives, which is a concern for eco-conscious consumers.
PEG purity concerns
The PEG component can potentially contain trace impurities like ethylene oxide if not properly refined, though this is rare in high-quality cosmetics.
Best for
- People with normal to dry skin who want a gentle, non-stripping cleanser
- Anyone looking for a lightweight moisturizer or sunscreen that spreads easily
Use caution if
- Those who strictly avoid silicones or PEG compounds for personal preference
Usage tips
Safety summary
Generally recognized as safe for topical use in cosmetics at concentrations up to 5%. Low irritation and comedogenic risk. As with any PEG-containing ingredient, quality control in manufacturing is important to avoid impurities.
Research notes
There is limited peer-reviewed research specifically on Lauryl Dimethicone PEG-10 Phosphate, but it is structurally similar to other silicone surfactants that have been reviewed by the CIR and found safe. Most evidence comes from formulation science rather than clinical studies.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. The Cosmetic Ingredient Review (CIR) has evaluated similar silicone surfactants and found them safe at typical concentrations.
- Common uses
- Cleansers, Makeup removers, Sunscreens, Moisturizers
- Environmental note
- Silicone derivatives like this one are not readily biodegradable and can accumulate in aquatic environments. Some brands are moving toward more biodegradable alternatives.
Good to know
- This ingredient is often found in 'micellar water' type cleansers because of its ability to lift makeup and dirt without rubbing.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use levels.
