Ingredient review
Dimethicone PEG-8 Lanolate
INCI: DIMETHICONE PEG-8 LANOLATE
A gentle silicone-lanolin hybrid that helps products spread smoothly and feel silky, but may not suit those avoiding silicones or lanolin derivatives.
In plain English
This ingredient is a hybrid molecule that combines a silicone (dimethicone) with a modified form of lanolin (a waxy substance from sheep's wool). It acts as an emollient, meaning it softens and smooths the skin by filling in gaps between skin cells. It also helps other ingredients mix together (emulsifier) and gives products a silky, non-greasy feel. Because it contains lanolin, it can be a concern for people with wool allergies, though the modification process reduces that risk.

Quick decision guide
Useful, but context matters
Dimethicone PEG-8 Lanolate 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 Lanolate.
- 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 ingredient created by chemically attaching a polyethylene glycol (PEG) chain to lanolin, then linking it to dimethicone. This makes it water-dispersible and less greasy than plain lanolin.
How it works
It forms a thin, breathable film on the skin that locks in moisture and reduces water loss. The silicone part gives a smooth, velvety texture, while the lanolin part provides emollient and emulsifying properties, helping oil and water phases blend in a formula.
Pros
Silky texture
Gives products a smooth, velvety feel that spreads easily and doesn't feel greasy.
Good moisturizer
Helps reduce water loss from the skin, keeping it hydrated and soft.
Cons and cautions
Potential allergen
Derived from lanolin, which can cause allergic reactions in people sensitive to wool products.
Contains PEGs
Polyethylene glycols are sometimes avoided due to concerns about contamination during manufacturing, though cosmetic-grade PEGs are considered safe.
Best for
- Those with dry or normal skin looking for a smooth, silky moisturizer
- People who enjoy silicone-based textures in their skincare
Use caution if
- Individuals with known allergies to lanolin or wool derivatives
- Those who strictly avoid silicones or PEG compounds in their routine
Usage tips
Safety summary
Generally considered safe for most skin types at typical use levels. The main concern is potential allergy to the lanolin component, though the modification reduces that risk. PEG compounds are safe in cosmetic-grade forms.
Research notes
Limited direct studies on this specific hybrid, but its components (dimethicone, lanolin, PEG-8) are well-studied and considered safe in cosmetics. The Cosmetic Ingredient Review (CIR) panel has reviewed dimethicone and lanolin derivatives and found them safe as used.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no concentration restrictions.
- Common uses
- Moisturizers, Foundations, Lip products, Hair conditioners
- Environmental note
- Silicones can persist in the environment, but this ingredient is used in low concentrations and is often part of rinse-off products.
Good to know
- The PEG modification makes this ingredient water-dispersible, so it rinses off more easily than plain dimethicone.
- It is often used in color cosmetics to improve wear and feel.
