Making Colored Lip Balm with Shea Butter and Iron Oxides: Preservative Needed?
คำถาม
I would like to make a colored lip balm using pure shea butter and color powder like Iron Oxides.
1. What is the recommended process for mixing the color powder into the shea butter?
2. Is a preservative needed for this type of formulation (pure shea butter + color powder)?
คำตอบ
Based on the conversation, you can mix pure shea butter with color powders like Iron Oxides to make a colored lip balm. As the staff mentioned, it's best to soften the shea butter slightly before adding the powder and mixing well.
Regarding the need for a preservative, since this formulation consists only of shea butter (a fat) and dry color powder, it is an anhydrous (water-free) product. Products that do not contain water generally do not require a preservative because microorganisms need water to grow. Therefore, a preservative is typically not necessary for a pure shea butter and color powder mixture.
Relevant products mentioned in the conversation include:
- Shea Butter (Organic)
- Iron Oxides (Red, Yellow, Black)
