Loose Powder Formula Review for Oil Control and Water Resistance

Subject: Review of Loose Powder Formula for Oil Control

Thank you for submitting your loose powder formula for review. The formula aims for oil control and moderate water resistance.

Here is the list of ingredients and their percentages you provided:

• Silk Talc Powder: 40%
• Silk Sericite Powder (Matte): 34.5%
• BB Micro Silk: 5%
• Magnesium Stearate: 9%
• Kaolin (China Clay): 5%
• MatteSilica™ (Silica): 3%
• AminoSilk (Lauroyl Lysine): 3%
• Allantoin: 0.5%

The total percentage is 100%, which is correct.

Based on the ingredients and their stated functions:

• Oil Control: Ingredients like Kaolin and MatteSilica™ are effective oil absorbers, which directly address the oil control goal.
• Texture and Feel: Silk Talc, Silk Sericite, and BB Micro Silk are common base powders that provide smooth texture and feel. AminoSilk also contributes to a smooth, slippery feel.
• Adherence: Magnesium Stearate helps the powder adhere to the skin. As noted in the feedback you received, 9% is on the higher side. It is recommended to start with a lower percentage (e.g., 5-6%) and adjust if needed, as adding too much can make the powder feel heavy or difficult to blend, and it's hard to remove once added.
• Water Resistance: AminoSilk (Lauroyl Lysine) is mentioned to help with water resistance, which aligns with your goal of moderate water resistance.
• Soothing: Allantoin is a good addition for its soothing and anti-irritant properties.

Regarding the feedback you received:

• The suggestion to add Beige Iron Oxides EasyMix is for adjusting the powder color to match skin tone, which is a standard practice for cosmetic powders.
• The advice to start with a lower percentage of Magnesium Stearate (5-6%) is practical, allowing you to test the adherence and adjust upwards if necessary.

Overall Assessment:
The formula appears well-structured for an oil-controlling loose powder. The combination of oil absorbers (Kaolin, Silica) and texture enhancers (Talc, Sericite, BB Micro Silk, AminoSilk) is appropriate. The inclusion of Allantoin is beneficial. Pay close attention to the Magnesium Stearate percentage during testing, starting lower as suggested. Adding colorants like Iron Oxides would be necessary if you aim for a tinted powder.

This formula seems like a good starting point for your loose powder project.
