Ingredient review
Dimethiconol Carnaubate
INCI: Dimethiconol Carnaubate
A gentle silicone wax that helps makeup and skincare last longer without feeling heavy or greasy.
In plain English
Dimethiconol Carnaubate is a hybrid ingredient made by combining a silicone oil (dimethiconol) with carnauba wax, a plant-based wax from Brazilian palm leaves. The result is a soft, waxy substance that spreads easily on skin, forms a flexible, breathable film, and helps other ingredients stay put. It gives products a smooth, silky feel without the stickiness of traditional waxes or the greasiness of oils. You'll often find it in long-wear lipsticks, lip balms, and water-resistant sunscreens because it helps the product adhere to skin and resist smudging or washing off.

Quick decision guide
Useful, but context matters
Dimethiconol Carnaubate 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 Dimethiconol Carnaubate.
- 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 ester formed by reacting dimethiconol (a silicone polymer) with carnauba acid derived from carnauba wax. It appears as a soft, waxy solid at room temperature and is designed to combine the best properties of silicones (smooth glide, non-greasy feel) and natural waxes (film-forming, water resistance).
How it works
When applied to skin, Dimethiconol Carnaubate melts slightly from body heat and spreads into a thin, even film. This film acts as a barrier that locks in moisture and helps pigments or active ingredients stay in place. The silicone portion gives a silky, non-tacky feel, while the wax portion provides structure and water resistance. It also helps control the viscosity of products, making them easier to apply and more stable over time.
Pros
Long-lasting wear
Helps lipsticks, foundations, and eye shadows stay put for hours without feathering or fading, even through eating or sweating.
Silky, non-greasy feel
Unlike many natural waxes, it glides on smoothly and leaves a soft, velvety finish that doesn't feel sticky or heavy.
Cons and cautions
Not eco-friendly
As a silicone-based ingredient, it is not biodegradable and may contribute to environmental accumulation, which is a concern for eco-conscious consumers.
Potential heaviness on oily skin
In high concentrations, the film it forms can feel slightly occlusive or heavy for those with very oily or acne-prone skin.
Best for
- Anyone looking for long-wear lip products or water-resistant sunscreens
- People who prefer a smooth, silky texture in their makeup and skincare
Use caution if
- Those who strictly avoid silicones for environmental or personal reasons
Usage tips
Safety summary
Dimethiconol Carnaubate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. However, like all silicones, it is not biodegradable, which is an environmental consideration.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found silicone waxes like Dimethiconol Carnaubate to be safe in cosmetic formulations. Studies show it forms effective water-resistant films without significant skin irritation or sensitization. Research on its environmental impact is limited, but silicone persistence is a known concern.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and other major markets. No known restrictions at typical use levels.
- Common uses
- Lipsticks, Lip balms, Long-wear foundations, Eye shadows, Water-resistant sunscreens
- Environmental note
- As a silicone derivative, it is not readily biodegradable. Some manufacturers are exploring bio-based alternatives to reduce environmental impact.
Good to know
- It is often used in combination with other silicones and waxes to fine-tune texture and wear.
- Despite being a wax, it does not clog pores (non-comedogenic) for most skin types.
