1. Color Properties:
* Hue: The basic color of the lipstick (e.g., red, pink, orange, purple). This is determined by the dyes and pigments used.
* Saturation (Chroma): The intensity or purity of the color. Highly saturated lipsticks are vibrant and bold, while less saturated ones are more muted or sheer.
* Value (Brightness): How light or dark the color is. A lipstick can be a deep, dark burgundy (low value) or a light, pastel pink (high value).
* Opacity: How much of the natural lip color is obscured by the lipstick.
* Opaque: Provides full coverage, completely covering the natural lip color.
* Semi-Opaque: Offers partial coverage; some of the natural lip color shows through.
* Sheer: Provides minimal coverage; the natural lip color is mostly visible, with just a hint of color.
* Color Payoff: The amount of color that is deposited onto the lips with a single application. High color payoff means a rich, noticeable color.
2. Texture & Application Properties:
* Creaminess: How soft and smooth the lipstick feels. Creamier lipsticks tend to glide on easily.
* Slip: The ease with which the lipstick moves across the lips. Good slip allows for even application without dragging.
* Drag: The opposite of slip. A lipstick with high drag feels like it's pulling or tugging on the lips during application.
* Waxy: The amount of wax present in the formulation. Waxes contribute to structure and firmness but can feel heavy if present in excess.
* Emolliency: The ability to soften and moisturize the lips. Emollients like oils and butters contribute to this property.
* Balm-like: Similar to emolliency, but often used to describe lipsticks that prioritize moisturization and comfort above intense color payoff.
3. Wear & Performance Properties:
* Long-Wearing/Long-Lasting: The ability of the lipstick to stay on the lips for an extended period without needing reapplication. This is often achieved through the use of polymers and film-forming agents.
* Transfer-Resistance: The extent to which the lipstick resists transferring to other surfaces (e.g., cups, clothing, skin). "Kiss-proof" or "smudge-proof" lipsticks are designed to minimize transfer.
* Fade Resistance: How well the color holds up over time without fading or losing intensity.
* Bleeding/Feathering: The tendency of the lipstick to migrate into fine lines around the lips. Lip liners can help prevent this.
* Smudging: The tendency of the lipstick to smear or smudge outside the lip line.
* Hydration: The ability of the lipstick to keep the lips moisturized and prevent dryness.
* Comfort: How the lipstick feels on the lips throughout the day. A comfortable lipstick won't feel dry, tight, or heavy.
4. Finish Properties:
* Matte: A flat, non-reflective finish with no shine. Often very long-wearing.
* Satin: A semi-matte finish with a subtle sheen. More comfortable than matte, but less long-wearing.
* Cream: A smooth, slightly glossy finish. Generally comfortable and hydrating.
* Glossy: A high-shine finish that reflects light. Often less pigmented and less long-wearing.
* Metallic/Shimmer: A finish with reflective particles (mica, glitter) that create a sparkly or luminous effect.
* Frosted: A finish with a pearlescent or opalescent sheen.
5. Stability Properties:
* Heat Stability: How well the lipstick holds its shape and consistency at high temperatures. Lipsticks can melt or soften in hot conditions.
* Cold Stability: How well the lipstick holds its texture and performance in cold temperatures. Some formulations can become too hard or brittle when cold.
* Color Stability: How the color resists fading or changing over time and exposure to light or air.
* Phase Stability: The resistance of the lipstick to separating into different components (e.g., oil separating from the pigment).
These properties are determined by the specific combination of ingredients used in the lipstick formula, including:
* Waxes: Provide structure and rigidity. (e.g., beeswax, carnauba wax, candelilla wax)
* Oils: Contribute to emolliency and slip. (e.g., castor oil, mineral oil, jojoba oil)
* Emollients: Soften and moisturize the lips. (e.g., shea butter, cocoa butter, lanolin)
* Pigments and Dyes: Provide color.
* Film Formers: Enhance longevity and transfer resistance.
* Preservatives: Prevent microbial growth.
* Antioxidants: Protect the formula from oxidation and rancidity.
* Fragrance: Provides a scent.
The ideal combination of these properties depends on the desired effect, performance, and target consumer.
