Fine Liquid Eyeliner 0.6g

Precision Application & Fine Lines:

• How: The primary film-formers (Styrene/Acrylates Copolymer and its Ammonium salt, plus Acrylates Copolymer in white) create a fluid yet controlled formula. Butylene Glycol and 1,3-Propanediol (in white) act as solvents/humectants, ensuring the right viscosity – thin enough for a fine brush tip to deliver a sharp line, but thick enough not to bleed immediately.
• Benefit: Allows for creating incredibly thin, crisp lines, winged flicks, or detailed graphic designs with ease and control.

Intense, Vivid, True-to-Tone Color Payoff:

• Black: Relies heavily on high-pigment-load CI 77266 (Carbon Black). The film-formers hold the pigment densely on the skin surface, preventing dilution or sheerness.
• White: Uses CI 77891 (Titanium Dioxide) as the main white pigment. The critical addition here is the tiny amounts of CI 77266 (Carbon Black), CI 77492 (Red Iron Oxide), and CI 77491 (Yellow Iron Oxide). These meticulously neutralize any inherent yellow or warm undertones in the titanium dioxide.
• Benefit: "Obsidian Rich Black" delivers a deep, pure, opaque black. "Light Feather Vivid White" achieves a bright, clean, cool-toned white without looking chalky, greyish, or yellowish – a significant challenge in white eyeliners.

Long-Lasting, Smudge-Proof & Transfer-Resistant Wear:

• How: This is the core function of the Styrene/Acrylates Copolymer system. These polymers form a flexible, water-resistant, and adherent film directly on the eyelid/skin/lash line:
• Styrene: Provides water resistance and durability.
• Acrylates: Provide flexibility and adhesion, preventing cracking or flaking.
• Ammonium Salt Version (Styrene/Acrylates Copolymer Ammonium): Enhances water resistance further and improves stability/compatibility within the formula.
• Acrylates Copolymer (White): Adds extra film-forming strength and adhesion, crucial for keeping dense white pigments locked in place.
• Benefit: Resists smudging from blinking, oily eyelids, humidity, or minor water exposure (like tears or light rain). Minimizes transfer to the upper eyelid ("hooding"). Stays put all day without fading or breaking down easily.

Flexible, Comfortable Wear (No Cracking/Tightness):

• How: The balance between Styrene (hardness/durability) and Acrylates (softness/flexibility) in the copolymers creates a film that moves with the skin. Butylene Glycol, 1,3-Propanediol, and Caprylyl Glycol provide subtle hydration.
• Benefit: Avoids the uncomfortable tight feeling, cracking, or flaking common with very rigid, vinyl-based liquid liners. Feels lightweight and comfortable on the delicate eye area.

Quick-Drying:

• How: The water-based formula (Water as the main ingredient) combined with volatile solvents like Butylene Glycol allows the product to set relatively quickly once applied. The film-forming polymers solidify as the water/solvents evaporate.
• Benefit: Reduces the risk of smudging during application or immediately after. Allows for building layers or opening eyes quickly without transferring wet liner.

Gentle Preservative System (Suitable for Sensitive Eyes in theory):

• How: Uses Phenoxyethanol (a widely accepted, broad-spectrum preservative) at a safe concentration (<1%), boosted by milder agents like 1,2-Hexanediol, Caprylyl Glycol, Ethylhexylglycerin (white), and Sodium Dehydroacetate. Avoids parabens and formaldehyde-releasers commonly flagged for sensitivity.
• Benefit: Formulated to minimize the risk of microbial growth while aiming for lower irritation potential compared to some older preservative systems. (Note: Individual sensitivities vary; patch testing is always recommended).

Stable Formula & Smooth Application:

• How: Ceteareth-25 acts as an emulsifier and stabilizer, ensuring the pigments and polymers remain evenly dispersed in the water base, preventing separation. It also contributes to a smooth, slightly creamy texture that glides on.
• Benefit: Consistent performance bottle-to-bottle. Smooth, even flow from the applicator without skipping or clumping.

Why It (Especially the White):

• White Liner Challenge: Formulating a truly vivid, opaque, long-wearing white liquid liner is notoriously difficult. Titanium Dioxide (CI 77891) often has yellowish undertones and can be chalky or prone to fading/cracking.

Cheeryep's Solution: They didn't just rely on Titanium Dioxide. They:

• Used multiple, robust film-formers (Acrylates Copolymer + Styrene/Acrylates Copolymer + Styrene/Acrylates Copolymer Ammonium) for maximum adhesion and durability.
• Precisely color-corrected the white using minuscule amounts of Black (CI 77266) and Iron Oxides (CI 77491/77492). This neutralizes yellow tones, resulting in that "Vivid White" claim.
• Included an extra humectant/solvent (1,3-Propanediol) likely to improve the texture and workability of the higher pigment load.

Summary of Key Benefits:

• Surgical Precision: For sharp lines and intricate details.
• Intense, Pure Color: Deep black, truly vivid cool white.
• All-Day Wear: Smudge-proof, transfer-resistant, water-resistant.
• Comfort: Flexible film, no cracking or tightness.
• Quick Setting: Minimizes smudging during application.
• Stable & Smooth: Reliable performance and application.
• Considered Preservation: Aimed at lower irritation potential.

This formulation leverages advanced polymer chemistry (Styrene/Acrylates systems) and sophisticated pigment balancing (especially in the white shade) to deliver high performance specifically tailored for the demands of liquid eyeliner. The focus is clearly on precision, intense color payoff, and exceptional longevity.

Obsidian Rich Black:

• Water (Aqua): The primary solvent, forming the base of the formula.
• Styrene/Acrylates Copolymer: A key film-forming agent that creates the flexible, water-resistant, and long-wearing layer on the eyelid.
• Butylene Glycol: A humectant (attracts moisture) and solvent that also helps improve product spreadability and texture.
• CI 77266 (Carbon Black): The black pigment providing intense color and opacity.
• Styrene/Acrylates Copolymer Ammonium: Another film-forming agent, often used to enhance water resistance, adhesion, and stability. The ammonium salt form can improve compatibility.
• Phenoxyethanol: A broad-spectrum preservative preventing microbial growth.
• 1,2-Hexanediol: Primarily a preservative booster and solvent, also acts as a mild humectant.
• Ceteareth-25: An emulsifier and surfactant. It helps blend water and oil-soluble components, stabilizes the formula, and can contribute to texture/thickness.
• Sodium Dehydroacetate: A preservative effective against fungi and yeasts.
