OUR STANDARDS
The substances we refuse to formulate with.
The following substances are restricted or prohibited in every Mazi Beauty product. Each is excluded because of evidence — or strong reasonable suspicion — of harm to skin, health, or the environment.
RESTRICTED OR PROHIBITED
Ingredients we never use.
- Aluminium powder
- Elemental aluminium (powder) is the third most abundant element on earth. At high doses it is a toxicant, and is never used in our products.
- Animal-derived ingredients
- We never use animal musks or animal fats. Animal-derived ingredients are prohibited, with these exceptions only: cholesterol, lactose, lanolin, and keratin.
- Benzalkonium chloride
- Bisphenol A (BPA)
- Butoxyethanol
- Butylated hydroxyanisole (BHA)
- A preservative linked to cancer, skin irritation, and hormone disruption.
- Camphor (>3%)
- Chemical sunscreens
- Some chemical sunscreens have been linked to hormone disruption. Mazi prohibits all chemical sunscreens, including (but not limited to): oxybenzone / benzophenone-3, avobenzone, octinoxate, homosalate, and octocrylene.
- Coal tar
- Ethanolamines (DEA / TEA / MEA / ETA)
- EDTA (ethylenediaminetetraacetic acid)
- Calcium disodium EDTA, tetrasodium EDTA, trisodium EDTA, etc. are chelating agents. These ingredients are not linked to consumer health issues, but they may be problematic for aquatic life.
- Formaldehydes
- Although rarely listed as an ingredient itself, formaldehyde 'releasers' or 'donors' often are — including tosylamide/formaldehyde resin, methylene glycol, paraformaldehyde, polyoxymethylene urea, methenamine, benzylhemiformal, and quaternium-15.
- Hydroquinone
- Typically used as a skin-lightening agent — inhibits melanin synthesis, causes skin irritation, and may cause discolouration.
- Isothiazolinones (all)
- Mercury and mercury compounds
- Methyl cellosolve (2-methoxyethanol)
- Banned in the EU. A solvent used as an additive in perfumes; can cause skin irritation.
- Petrolatum and paraffin
- Petrolatum is a semisolid mixture derived from processed petroleum. Concerns include unsustainable sourcing and possible PAH contamination.
- Nanoparticles
- Including titanium dioxide, zinc oxide, silver, fullerenes, silica, carbon black, and quartz.
- Parabens
- Including butylparaben, benzylparaben, ethylparaben, isobutylparaben, isopropylparaben, methylparaben, and propylparaben.
- PEGs
- Allowed only if tested for 1,4-dioxane with statement and/or test data.
- PFAS (including PTFE)
- Phthalates
- Plasticising chemicals. Some appear on ingredient labels, but many remain undisclosed under the umbrella term 'fragrance.'
- Phenoxyethanol (>1%)
- Despite being a 'controversial' ingredient, phenoxyethanol has a similar — or better — safety profile compared to other widely used preservatives. The SCCS considers 2-phenoxyethanol safe at a maximum concentration of 1.0%.
- Plastic microbeads
- Polyacrylamide and acrylamide
- Propylene glycol (>0.1%)
- Quaternary amine compounds (as preservatives)
- Excluding: hydroxypropyl guar, hydroxypropyltrimonium chloride, and cocodimopropryl quar hydroxysultaine.
- Resorcinol
- Retinyl palmitate
- As a retinoid, this ingredient may increase sun sensitivity when applied and worn in direct sunlight.
- Cyclic silicones
- Including cyclotetrasiloxane (D4), cyclopentasiloxane (D5), cyclohexasiloxane (D6), and cyclomethicone. Data indicates some of these may have reproductive and developmental toxicity.
- Shellac
- Styrenes
- Including bromostyrene, DEA-styrene/acrylates/DVP copolymer, sodium styrene/divinylbenzene copolymer, styrene oxide, and styrene.
- Sulfates
- Sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES).
- Talc
- Allowed only with an asbestos-free statement and/or test data.
- Toluene
- Triclosan and triclocarban
- Antibacterials used in personal care and home cleaning products. They are persistent in the environment and may be associated with hormone disruption.
- Triphenyl phosphate (TPHP)
- Xylenes
FRAGRANCE RESTRICTIONS

In addition to the substances above, the following are prohibited from any fragrance formulation in our products.
- Dibutyl phthalate (DBP)
- Butyl benzyl phthalate (BBP)
- Di(2-ethylhexyl) phthalate (DEHP)
- Diisodecyl phthalate (DIDP)
- Diisononyl phthalate (DINP)
- Di-n-hexyl phthalate (DNHP)
COLOURING RESTRICTIONS
Minimal, non-irritating colour only.
To create a visually enjoyable experience, we sometimes formulate with a minimum amount of non-irritating colouring agents.
Synthetic iron oxides are man-made but produced from natural ores and minerals, and are 100% safe to use in cosmetic formulations.
