Chapter II · The Ingredients
We scored every ingredient individually. Some impressed us. Others raised serious questions.
Kaolin
A natural clay that helps to mattify lipstick and bind excess oil.
Caprylic/Capric Triglyceride
A nourishing neutral oil derived from coconut fat that makes the skin supple and is very well tolerated.
Copernicia Cerifera (Carnauba) Wax
A hard plant wax that gives the product stability and has a smoothing effect.
Tocopherol
Pure Vitamin E that protects the lips from free radicals and prevents the product from going rancid.
Titanium Dioxide (CI 77891)
A mineral white pigment considered safe and provides the necessary opacity for the color.
Carmine (CI 75470)
A red dye of animal origin, which is safe but avoided by vegans.
Dimethicone
A silicone oil that makes the texture smooth but is environmentally difficult to degrade.
Hydrogenated Polyisobutene
A synthetic polymer that increases smoothness but is considered environmentally difficult to degrade.
Bismuth Oxychloride (CI 77163)
A mineral pigment that imparts a metallic sheen but can cause itching in sensitive skin.
Paraffin
A mineral oil-based wax that retains moisture in the skin but is environmentally questionable.
Yellow 5 Lake (CI 19140)
A synthetic dye suspected of causing intolerances in sensitive skin.
Red 7 Lake (CI 15850)
A synthetic dye that provides intense color results but has a certain irritation potential.
PVP/Hexadecene Copolymer
A synthetic film former that improves durability but is considered difficult-to-degrade microplastic.

Chapter III · The Deep Dive
The MAC Ruby Woo Lipstick is an iconic, matte lipstick known worldwide for its extremely high pigmentation and long-lasting texture. The formulation is based on a blend of various waxes, silicones, and a variety of color pigments to achieve the characteristic matte finish.
The formulation is a typical example of a performance product that relies heavily on synthetic ingredients. While skin tolerability is good for most users, the product contains mineral oil-based waxes and synthetic polymers, which are ecologically critical.
| Ingredient | Rating | Function & Effect |
|---|---|---|
| Dimethicone | 🟡 | Silicone oil, provides a silky feel and good spreadability. |
| Kaolin | 🟢 | Natural clay, mattifies the texture and absorbs excess oil. |
| Paraffin | 🟡 | Mineral wax, serves as a consistency enhancer, but is poorly biodegradable. |
| Caprylic/Capric Triglyceride | 🟢 | Neutral oil from coconut fatty acids, has nourishing and re-fattening effects. |
| Copernicia Cerifera Wax | 🟢 | Carnauba wax, a natural plant wax that provides hardness and shine. |
| Tocopherol | 🟢 | Vitamin E, protects both skin and product as an antioxidant. |
| Vanillin | 🟢 | Flavor and fragrance, gives the typical vanilla scent. |
| PVP/Hexadecene Copolymer | 🔴 | Synthetic polymer (film former), considered poorly biodegradable (microplastic issue). |
| Titanium Dioxide (CI 77891) | 🟢 | White pigment and mineral UV protection, considered safe in lipsticks. |
| Carmine (CI 75470) | 🟢 / 🟡 | Natural red dye (carmine), harmless but not vegan (of animal origin). |
| Yellow 5 Lake (CI 19140) | 🟡 | Synthetic dye that can trigger reactions in sensitive individuals. |
| Iron Oxides | 🟢 | Earth pigments for coloring, considered very safe and well tolerated. |
The ecological footprint of this product is to be classified as critical due to its conventional composition.
Conclusion: The MAC Ruby Woo Lipstick impresses with its professional performance and color depth, but uses a chemical-synthetic base. Ingredients like Paraffin and various polymers make it a classic conventional cosmetic product without a focus on sustainability.
Recommendation:
High Concern — Flagged Ingredient
PVP/Hexadecene Copolymer
A synthetic film former that improves durability but is considered difficult-to-degrade microplastic.
