Lip Balm Formula Adjustments

Softness for Tube Packaging

To make the lip balm softer so it can be easily dispensed from a squeeze tube, you need to reduce the amount of solidifying agents. Based on the previous advice, the key ingredient to adjust is Beeswax. Reduce the Beeswax concentration significantly, aiming for a range of 1-3% of the total formula. This will result in a much softer texture compared to using 10% Beeswax.

Clear/Shiny Texture

As mentioned previously, achieving a completely clear or shiny texture is not possible with a formula that contains wax like Beeswax or Shea Butter. These ingredients naturally create an opaque or cloudy appearance. If a clear texture is a priority, you would need to formulate an oil gel using specific gelling agents for oils, but this would result in a different feel and consistency than a traditional lip balm. Given your goal of a soft balm in a tube, the current ingredient approach is more suitable, even if it means the texture is not clear.

Adding Pink Color

You want to add a pink color to the lip balm itself for visual appeal, with minimal transfer to the lips. While any added color will transfer to some extent, using a pigment at a low concentration will color the balm and provide only a subtle tint on the lips.

Based on the search results for pink pigments:

• Ultramarine Pink: This is a standard pink pigment powder (CI 77007) that can be dispersed in oil. It is commonly used in makeup products. Using a small amount (e.g., 0.1-1%) should color the balm nicely.
• D&C Red 27 Color Changing Pigment: This pigment changes color based on pH, typically turning pink when it comes into contact with the skin. It dissolves in oil. This would give a color-changing effect on the lips rather than just coloring the balm.
• Purple Sweet Potato Pigment: This is a natural pigment powder that is mixed into the water phase. Its color is highly dependent on the pH of the formula (pink/red at low pH, blue at higher pH). You would need to ensure your balm's water phase pH is suitable for a pink color.

For simply coloring the balm pink with the least amount of staining, Ultramarine Pink is likely the most suitable option. Start with a very low percentage (e.g., 0.1%) and increase gradually until you achieve the desired color intensity in the balm. Remember that some color transfer to the lips is unavoidable when using pigments.
