Reducing Viscosity of Infallible Matte Resistance Lip Base (ID 127663) for Dip Tube Filling
Question
The customer is using the product base Infallible Matte Resistance Lip (ID 127663), which is intended to be a long-lasting, matte, non-sticky, and unscented liquid lip formulation.
The current formulation is highly viscous and thick, making it impossible to fill into a dip tube container.
We require recommendations on methods or ingredients (including appropriate percentages or an example formula adjustment) to significantly reduce the viscosity of the base, making the texture more liquid, while strictly maintaining the following characteristics:
- Matte texture
- Not sticky
- Long-lasting durability
- Unscented base
The solution must be suitable for an independent formulation adjustment.
Answer
The "Infallible Matte Resistance Lip" base (ID 127663) is highly viscous due to its high concentration of film-formers and silicone elastomers (like TRIMETHYLSILOXYSILICATE, DIMETHICONE CROSSPOLYMER, and C30-45 ALKYLDIMETHYLSILYL POLYPROPYLSILSESQUIOXANE). To reduce the viscosity for easier filling into a dip tube container while maintaining the matte, non-sticky, and long-lasting properties, the most effective solution is to increase the amount of the volatile solvent, Isododecane.
Isododecane is already the primary solvent in the formula (25%) and is crucial for the product's performance. It thins the product for application and then evaporates quickly, leaving the durable film-formers behind.
Recommended Modification
You should dilute the base with additional Isododecane (IDs 228, 7915).
| Component | Recommended Usage Rate | Purpose |
|---|---|---|
| Infallible Matte Resistance Lip Base (ID 127663) | 85% - 95% | The core product, providing color, matte finish, and long-lasting properties. |
| Isododecane (ID 228 or 7915) | 5% - 15% | Volatile solvent to reduce viscosity (thin the product) without leaving a sticky residue. |
Suggested Starting Point:
Start with a 10% dilution (90% Base + 10% Isododecane) and test the viscosity. If it is still too thick, you can increase the Isododecane up to 15%.
- Example Formula (10% Dilution):
- Infallible Matte Resistance Lip Base (ID 127663): 90%
- Isododecane (ID 228 or 7915): 10%
Important Considerations
- Testing: Always test a small batch first to ensure the new viscosity is suitable for your filling equipment and that the final film properties (matte finish, durability) are still acceptable.
- Film Integrity: Diluting the base reduces the concentration of the film-forming polymers. While Isododecane is volatile, excessive dilution (above 15%) may result in a slightly thinner film or reduced long-lasting performance.
- Mixing: Add the Isododecane slowly to the base while stirring gently but thoroughly until the mixture is completely homogeneous and the desired viscosity is achieved. Ensure all pigments and powders remain uniformly dispersed.
