Lip Tint (Etude Style)

Lip tints typically have a watery or gel-like texture and provide a staining effect on the lips. To achieve this, you'll need a water base, water-soluble colorants that stain, a gelling agent to create the desired texture, and potentially a film former for enhanced longevity.

Recommended Ingredients:

• Water Phase: Purified Water
• Gelling Agent:
  • Aristoflex AVC (Product ID: 7446): A powder that forms a clear gel in water and can help stabilize the formula.
  • AnyGel™ (Product ID: 1282): Another option for creating a gel texture in water-based formulas.
• Colorants (Water-Soluble Staining Dyes):
  • Acid Red 52 (Direct Dyes) (Product ID: 9069): A water-soluble dye that provides a staining effect.
  • FD&C Red No.4 (CI 14700) HiStain™ (Product ID: 9217): A water-soluble red color specifically noted for good adherence and long-lasting stain.
  • Other water-soluble dyes like Acid Orange 7 (Product ID: 9070) or Acid Yellow 3 (Product ID: 9071) can be used to adjust the shade.
• Film Former (for Longevity):
  • Comfort Film (Water Base) (Product ID: 9095): A water-based film former that creates a non-sticky film, helping the color last longer on the skin.
  • Polyacrylate-21 (Water Base, Gloss & Flexible) (Product ID: 125823): Another water-based film former that adds gloss and flexibility to the film.
• Preservative: To prevent microbial growth in the water-based formula.

Basic Guide for Lip Tint:

1. Prepare the water phase by adding the gelling agent to purified water and mixing until a uniform gel is formed. Follow the recommended usage rate for the chosen gelling agent.
2. Dissolve the water-soluble staining dyes in a small amount of water before adding them to the main water/gel phase. Add color gradually until the desired shade is achieved.
3. Add the water-based film former to the mixture and mix well.
4. Add a suitable preservative according to the manufacturer's instructions.
5. Mix thoroughly until all ingredients are evenly dispersed and the texture is smooth.

Matte Liquid Lipstick (NYX Style)

Matte liquid lipsticks typically use an oil or silicone base with pigments dispersed within, and they dry down to a transfer-resistant, matte finish, often achieved with volatile carriers and film formers. The staff's suggestion of Hectorite Oil Gel, EASYMIX™ COLOR, and Mineral Oil is a good starting point.

Recommended Ingredients:

• Oil/Silicone Base:
  • Mineral Oil: As suggested by the staff.
  • Isododecane (Ultra Lite) (Product ID: 7915): A volatile, lightweight oil that helps the product dry down to a matte, transfer-resistant finish. It's a common base for long-wearing lipsticks.
• Thickener / Gelling Agent (to suspend pigments):
  • Hectorite Gel™ (Mineral Oil Base) (Product ID: 664): This is specifically designed to thicken mineral oil and suspend pigments, and is mentioned in relation to NYX Soft Matte Lip Cream.
  • Hectorite Gel™ (Isododecane Base, eq. Bentone Gel ISD V) (Product ID: 1083): Similar to the Mineral Oil base version, but uses Isododecane, which is beneficial for a matte, quick-drying formula.
• Pigments:
  • EASYMIX™ COLOR (e.g., Red Iron Oxides EasyMix™ (Product ID: 276), White Oxides EasyMix™ (Product ID: 274), Yellow Iron Oxides EasyMix™ (Product ID: 275), Black Iron Oxides EasyMix™ (Product ID: 277), Beige Iron Oxides EasyMix™ (Product ID: 495)): These pre-dispersed pigments are easy to mix into oil/silicone bases and provide good color payoff and adherence. Use a combination to achieve the desired color.
• Film Former (for Longevity and Transfer Resistance):
  • Silicone Film (Soft Film, Low Viscosity, Isododecane Base) (Product ID: 31600): A silicone polymer dissolved in Isododecane that forms a durable, waterproof, and transfer-resistant film. Essential for a long-wearing matte finish.
• Other potential ingredients: Emollients for comfort, fillers for texture, and preservatives.

Basic Guide for Matte Liquid Lipstick:

1. Combine the oil/silicone base ingredients (Mineral Oil, Isododecane).
2. Add the chosen Hectorite Gel to the oil phase and mix thoroughly. High shear mixing (like using a homogenizer or high-speed mixer) is often needed to properly activate the Hectorite gel and create a stable suspension for the pigments.
3. Slowly add the EASYMIX™ pigments to the thickened oil phase. Mix very well to ensure the pigments are fully dispersed and there are no streaks or particles. Adjust pigment concentration to achieve the desired color intensity (typically 10-30% as suggested by staff, but can vary).
4. Add the Silicone Film and any other desired emollients or fillers to the mixture and mix until uniform.
5. Add a suitable preservative if necessary (depending on the formula composition and potential for water contamination).
6. Mix thoroughly. The final product should be a smooth, liquid consistency that dries down to a matte finish.

Remember to always work in a clean environment and follow good manufacturing practices. It is recommended to start with small batch sizes when developing new formulations.
