Natural Preservatives and Whitening in Lip Balm

Natural Preservatives for Lip Balm

For natural preservatives suitable for lip balm formulations, which are typically oil-based or water-in-oil emulsions, consider the following:

• Thyme Care™: This natural preservative is extracted from Thyme and Bois De Rose. It is soluble in oil and glycols and can withstand heat up to 80°C for a short period, making it suitable for incorporation into oil-based formulas.
• Preserve-Free BHL™: While not classified as a traditional preservative, it offers high efficacy and can be dispersed in oil, making it suitable for oil-based formulas like lip balm. It can also withstand heat up to 80°C for a short time.

When formulating, always perform a challenge test to ensure the preservative system is effective for your specific formula.

Using Lemon Peel Bioferment and Soy Lecithin in Lip Balm

Yes, it is possible to use Lemon Peel Bioferment as a whitening agent in a lip balm formulation by using Soy Lecithin as an emulsifier.

• Lemon Peel Bioferment: This ingredient is a water-soluble extract known for its tyrosinase inhibiting properties, making it effective for whitening. It needs to be added to the water phase of your formulation at a temperature below 40°C and within a pH range of 3.5-7.
• Soy Lecithin: This is a natural liquid emulsifier suitable for creating water-in-oil emulsions, which are common in lip balm formulations that contain a water phase. It is dissolved in the oil phase, typically with heating.

To incorporate Lemon Peel Bioferment into an oil-based lip balm, you would create a water-in-oil emulsion. Dissolve the Lemon Peel Bioferment in the water phase. Prepare the oil phase containing the Soy Lecithin (dissolved with heat). Combine the phases according to standard emulsification procedures, ensuring the temperature is below 40°C when adding the Lemon Peel Bioferment.
