can you compost makeup?
No — cosmetics are built on silicones, film-forming polymers, and preservatives chosen to stop microbial growth. Trash old products.
which bins can take it?
- hot pile no
- cold pile no
- worm bin no
- bokashi no
- tumbler no
- curbside no
- curbside: Cosmetics are a household product, not an organic feedstock — carts reject them.
why?
Every liquid or cream cosmetic is preserved with phenoxyethanol, parabens, or benzoates so the formula stays sterile for years on a shelf, which is a direct instruction to the organisms in your pile to stop working. Foundations and long-wear products add dimethicone and acrylate copolymers, while cosmetic glitter is usually PET film cut into flakes that never leave the soil.
watch out for
- Loose mineral powders — iron oxides, kaolin clay, mica, zinc oxide — are geological material that won't poison a pile, but they don't compost either; they simply become dust in the finished batch.
- Large volumes of liquid cosmetics belong at a household hazardous waste drop-off rather than down a drain, particularly on a septic system.
what to do instead
Trash unwanted products in their containers, and take big or unidentifiable liquids to a household hazardous waste event. Clean glass jars and metal palettes recycle once scraped out, and some brands run mail-back programs for compacts and tubes.

- Cotton Pads — The pad you take makeup off with can compost; the makeup on it is the part that can't.
quick answers
What about natural or vegan makeup?
Plant-oil balms and pigments suspended in beeswax genuinely biodegrade, and a smear won't hurt a pile. It's still not a disposal route — a whole jar is a concentrated dose of oil and pigment landing in one spot.
Can expired makeup go down the drain?
No. Oils and waxes feed the fat deposits that block sewer lines, and titanium dioxide and preservatives pass through treatment plants unchanged. Scrape solids into the trash and wipe the container with a paper towel.
