Powdered Kohl:
Traditionally, kohl was made from:
* Galena (Lead Sulfide): This is the most traditional and controversial ingredient. It provides the intense black color and is believed by some to have medicinal properties (though this is largely unfounded and carries health risks).
* Stibnite (Antimony Sulfide): Another dark mineral used as a colorant. Like galena, it has potential health concerns.
* Other Ingredients (Varied): Frankincense, myrrh, rose petals, sandalwood, soot, olive oil, and other herbs and spices were sometimes added for perceived medicinal benefits, fragrance, or to improve texture.
Modern kohl powders usually try to avoid lead. They often contain:
* Iron Oxides (CI 77499): A common black pigment, considered safe.
* Carbon Black (CI 77266): Another black pigment, also considered safe when used properly (although there have been some concerns around inhalation of ultrafine particles).
* Other Pigments: Other mineral pigments like ultramarines, or even titanium dioxide (for a lighter, softer look).
* Binding Agents: These help the powder adhere to the skin. Examples include:
* Stearates (like zinc stearate or magnesium stearate)
* Silica
* Talc (though its use is decreasing due to potential asbestos contamination concerns)
Liquid Eyeliner:
Liquid eyeliners generally consist of three main components:
1. Pigments: Provide the color.
* Black: Carbon black (CI 77266), Iron Oxides (CI 77499)
* Other Colors: Titanium dioxide (CI 77891 - white), ultramarines (CI 77007 - blue), Chromium Oxide Greens (CI 77288), Ferric Ferrocyanide (CI 77510 - blue), etc.
2. Film Formers: Create a flexible film that adheres to the skin and helps the eyeliner stay in place. These are often polymers.
* Acrylates Copolymer
* Styrene/Acrylates Copolymer
* Polyurethane
* PVP (Polyvinylpyrrolidone)
3. Liquid Base (Vehicle): Carries the pigments and film formers and allows for smooth application.
* Water (often the primary ingredient)
* Alcohol (helps with quick drying, but can be drying to the skin)
* Glycols (like propylene glycol or butylene glycol - act as humectants, drawing moisture to the skin)
Other Additives in Liquid Eyeliner:
* Thickeners: Help control the viscosity of the formula (e.g., cellulose gum, xanthan gum).
* Surfactants (Emulsifiers): Help mix ingredients that don't naturally blend, like oil and water (e.g., polysorbates).
* Preservatives: Prevent microbial growth (e.g., phenoxyethanol, potassium sorbate, sodium benzoate).
* pH Adjusters: Ensure the formula is at a safe and comfortable pH for the skin (e.g., citric acid, sodium hydroxide).
* Humectants: Help retain moisture (e.g., glycerin, hyaluronic acid).
Pencil Eyeliner:
Pencil eyeliners are essentially colored waxes and oils.
1. Waxes: Provide structure and hardness to the pencil.
* Carnauba wax
* Candelilla wax
* Beeswax
* Synthetic wax (e.g., microcrystalline wax)
2. Oils and Emollients: Contribute to the smoothness and glide of the pencil.
* Castor oil
* Coconut oil
* Vegetable oil
* Caprylic/Capric Triglyceride
* Isopropyl Myristate
3. Pigments: Same as liquid eyeliner (Carbon Black, Iron Oxides, Titanium Dioxide, etc.).
4. Fillers: Add bulk and help with texture.
* Talc (though its use is decreasing)
* Mica
* Silica
* Kaolin clay
5. Binders: Hold the ingredients together.
* Stearates (like zinc stearate or magnesium stearate)
6. Antioxidants: Help prevent the oils from going rancid (e.g., Tocopherol - Vitamin E).
7. Preservatives: Similar to liquid eyeliner, to prevent microbial growth (e.g., phenoxyethanol).
Important Considerations:
* Ingredient Lists: Always check the specific ingredient list of the product you are considering, as formulations vary greatly.
* Potential Allergens: Be aware of potential allergens or irritants. Common ones include certain preservatives, fragrances, and dyes.
* Safety: Be especially cautious with traditional kohl, particularly if it contains lead. Look for modern, lead-free alternatives.
* Quality: Opt for reputable brands that adhere to safety standards and rigorous testing.
* EU and FDA Regulations: Regulations on ingredients vary by country, so a product deemed safe in one region may not be in another.
