Ingredient Suitability for Loose Powder

Here's a look at whether the three ingredients you asked about can be used in a loose powder makeup formula:

1. Polymethylsilsesquioxane

This ingredient is suitable for loose powder formulations. It is a powder available in various particle sizes (2, 4.5, 7, and 10 microns). It provides a soft-focus effect, helps to blur the appearance of wrinkles, and gives the powder a smooth, silky feel. It also has oil absorption properties, which is beneficial in makeup powders. It can be dispersed into powder formulas.

2. SelectSorb™ (High Oil Absorption PMMA)

This ingredient is also suitable for loose powder formulations, especially for oil control. It is a powder (8 microns) specifically designed for high, selective absorption of skin oil without absorbing water. This helps reduce skin oiliness and improves skin feel in the product. It can be mixed into powder formulas in the final step.

3. Pure-Succinic™ (Succinic Acid, High-Purity)

This ingredient is generally not suitable for typical anhydrous loose powder formulations. While it is a powder, its primary functions (anti-acne, preservative) require it to be dissolved in water within a specific pH range (3.5-6.5) to be effective. Loose powders are typically anhydrous (contain no water), and adding a water-soluble acidic powder like Succinic Acid directly into an anhydrous powder blend would likely not provide its intended benefits and could potentially cause formulation issues.

In summary: Polymethylsilsesquioxane and SelectSorb™ (High Oil Absorption PMMA) can be successfully incorporated into a loose powder makeup formula to improve texture, feel, soft-focus effect, and oil control. Pure-Succinic™ (Succinic Acid) is generally not suitable for this type of anhydrous formulation.
