Loose Powder Formulation Feedback

Thank you for sharing your loose powder formulation! It's great that you've experimented and found a formula you like.

Based on your ingredients and desired properties (soft, lightweight, sun protection, easy blending), your proposed formula is a good starting point. The combination of Mica, Sericite, Magnesium Stearate, Bismuth Oxychloride, and Lauroyl Lysine is suitable for achieving a soft, smooth, and blendable texture. Allantoin is a nice addition for skin soothing.

Regarding the percentages:

• The total percentage of your listed ingredients (excluding color oxide and preservative) is 91.3%. This leaves approximately 8.7% for color oxides to reach 100%, which is a reasonable amount for adjusting the shade.
• As the staff previously advised, a preservative like Phenoxyethanol is not necessary in a dry powder formulation as microorganisms cannot grow without water.
• The percentages for the other ingredients seem appropriate for a loose powder base aiming for the properties you described.

Recommendations and Considerations:

• Sun Protection: Your formula includes Titanium Dioxide (5%) and Zinc Oxide (5%), totaling 10%. This combination provides some level of broad-spectrum UV protection. As the staff mentioned, using the silicone-coated versions like Titanium Dioxide 200nm EasyDisperse (ID 236, same ID but specific type) and Zinc Oxide 200nm EasyDisperse (ID 248) can significantly improve the texture, making it feel smoother and adhere better to the skin compared to standard micronized versions (ID 236, ID 292). While your chosen types are functional, the coated versions are recommended for enhanced cosmetic elegance.
• Texture and Cost: The staff suggested Silk Talc Powder (ID 283) as a cost-effective alternative to Silk Mica (ID 291) or Silk Sericite (ID 372). It can provide similar softness and slip.
• Coloring: To achieve a pinkish-white shade, you will need to mix red Lake colors (see category ID 47) with Titanium Dioxide (ID 236, especially the coated version ID 236). Iron Oxides alone (like Beige Iron Oxides EasyMix™ ID 495) are typically used for skin-tone shades (yellow, red, black, brown) and cannot create a pink hue without a red Lake.

Mixing Instructions (General):

Making loose powder is relatively simple, involving thorough blending of dry ingredients:

1. Weigh: Accurately weigh all your ingredients according to your desired percentages.
2. Combine: Place all the powder ingredients (base powders, sunscreens, actives, colorants) into a mortar and pestle, a cosmetic blender, or a suitable mixing container.
3. Mix: Blend the powders thoroughly. If using a mortar and pestle, grind gently to break up any clumps and ensure even distribution. If using a blender, mix until the powder appears completely uniform in color and texture. For best results and a smooth finish, you can pass the mixture through a fine sieve multiple times.
4. Check: Ensure there are no streaks of color or visible particles of individual ingredients.

Regarding your other questions from the conversation:

• Pressed Powder: As the staff explained, making pressed powder requires specialized hydraulic pressing equipment to prevent the powder from cracking or breaking over time. Manual pressing is generally not recommended for commercial quality products.
• Stock Status: Beige Iron Oxides EasyMix™ (ID 495) and Silk Sericite Powder (Matte, Methicone Coated) (ID 372) are currently in stock.
• Product Naming: Unfortunately, we cannot provide specific product name suggestions as this is a marketing decision best made based on your brand identity and target market.

Your formula seems promising for a nice loose powder! Experimenting with the suggested coated sunscreens or Talc might further enhance the feel.
