What it is
A silicone polymer used as a skin-conditioning agent and hair smoother.
Why vegan
Lab-synthesized from silicon; no animal source.
What a “Vegan” verdict means
A vegan verdict means the ingredient itself contains no animal-derived material and is not conventionally produced using animal inputs. It does not guarantee the finished product is vegan: the same label can carry dairy, egg or honey elsewhere in the list, and shared production lines can add 'may contain milk' warnings.
Where you'll find it
- Foundations and primers
- Hair serums
- Skincare

How to read the label
Dimethicone belongs to the cosmetic ingredients family. These are the terms worth scanning for on any ingredient list in this category:
- Lanolin
- Keratin
- Collagen
- Elastin
- Guanine
- Squalene
- Carmine
- Cera alba
- Silk amino acids
- Tallow
- Read the INCI list from the bottom for pigments and waxes, where animal entries cluster.
- Leaping Bunny answers testing; a vegan trademark answers ingredients. Look for both.
- 'Squalane (olive-derived)' or 'plant squalane' is an explicit vegan claim; unqualified squalane usually is too but is worth checking.
- Pearlescent products may use guanine from fish scales; mica is the mineral alternative.
Mistakes to avoid
| Where it catches people out | What to do |
|---|---|
| 'Natural' skincare | Natural often means lanolin, beeswax and honey — the opposite of vegan. |
| Shimmer and highlighter | Guanine from fish scales gives the classic pearl effect. |
| Hair repair products | Keratin is typically from feathers, hooves or wool. |
Cosmetic ingredients in context
Cosmetics use the INCI naming system, which is standardised worldwide but says nothing about whether an ingredient came from a plant or an animal. Lanolin, keratin, collagen, silk amino acids, squalene and guanine are all common animal-derived INCI entries.
Two separate questions matter in this category and are often conflated: whether the formula contains animal ingredients (vegan) and whether the product or its ingredients were tested on animals (cruelty-free). A product can be one without the other.
Squalene and squalane illustrate the ambiguity neatly — historically shark liver oil, now predominantly olive or sugarcane derived, with the same INCI name for both.
Does certification help? Leaping Bunny plus a vegan trademark together are the only reliable shortcut, because INCI names cannot express ingredient origin.

FAQ
- Is dimethicone tested on animals?
- The ingredient itself is widely accepted as safe and is not typically retested. Buy from cruelty-free brands to be sure.
- Is cruelty-free the same as vegan?
- No. Cruelty-free means no animal testing; vegan means no animal ingredients. A cruelty-free lipstick can still contain carmine and beeswax.
- Is lanolin cruelty-free?
- It is a wool grease from shorn sheep, so no animal is killed, but it is an animal product and therefore not vegan.
