Loose Powder Formulation Feedback

Question

I have created a loose powder formulation and would like feedback. My formula includes ingredients like Silk Mica Powder, Silk Sericite Powder, AminoSilk™ (Lauroyl Lysine), Magnesium Stearate, BB Micro Silk™ (Silica), Zinc Oxide, Titanium Dioxide, Beige Iron Oxides, and Bismuth Oxychloride. I am concerned that the Titanium Dioxide might cause a white cast ('ขาวผีหลอก') if the amount is too high. Could you please review my formula and provide feedback on its texture, oil control, and the potential for white cast?

Your proposed loose powder formulation looks good and contains ingredients suitable for achieving a soft, silky feel with moderate oil control.

Here's a breakdown of how the ingredients contribute:

Soft & Silky Feel:
- Silk Mica Powder and Silk Sericite Powder provide a smooth base and silky texture.
- AminoSilk™ (Lauroyl Lysine) is excellent for imparting an exceptionally soft and luxurious feel.
- Magnesium Stearate helps with slip and adhesion.
Oil Control:
- BB Micro Silk™ (Silica) is a key ingredient for absorbing excess oil and providing a matte finish.
- Zinc Oxide also offers some oil-absorbing properties.
Other Components:
- Titanium Dioxide and Zinc Oxide provide mineral sun protection.
- Beige Iron Oxides provide color to match skin tone and help counteract the white cast from the UV filters.
- Bismuth Oxychloride adds a luminous or glowing effect.

Regarding the feedback about Titanium Dioxide causing a white cast, it's a valid point. The inclusion of Iron Oxides in your formula is good as it helps to tint the powder and reduce the white appearance. The amount of TiO2 and ZnO in your formula is relatively low, which also helps minimize the white cast compared to formulas aiming for very high SPF. You may need to adjust the ratio of Titanium Dioxide, Zinc Oxide, and Iron Oxides slightly based on the desired level of sun protection and the resulting color and white cast on your skin.

Overall, this is a solid starting formula for a soft, silky, oil-controlling loose powder with added sun protection and color. The small batch size is perfect for testing. Mix it well and try it out to see if the texture, oil control, and color match your expectations!
