Formulating Pressed Powder Foundation with Sunscreen for Coverage and Longevity
Question
I am looking for guidance on formulating a pressed powder foundation that includes sunscreen properties. The desired characteristics are:
- Smooth, clear coverage
- Long-lasting wear
Based on the previous suggestion to study from Oil Thick™ Hard (Dextrin Palmitate), how can I develop a formula for this type of product, considering the necessary components like oil absorbers, pigments, UV filters, binders, and skin conditioners?
Answer
Hello,
Regarding the formula for a pressed powder foundation with sunscreen that provides smooth, clear coverage and long-lasting wear, it requires several ingredients to achieve the desired texture and properties.
Based on the previous staff recommendation to study from [url=http://www.myskinrecipes.com/shop/%E0%B8%AA%E0%B8%A3%E0%B9%89%E0%B8%B2%E0%B8%87%E0%B9%80%E0%B8%99%E0%B8%B7%E0%B9%89%E0%B8%AD%E0%B9%80%E0%B8%88%E0%B9%88%E0%B8%A5-thickener/1047-oil-thick-dextrin-palmitate.html:11v6jhbk]Oil Thick™ Hard[/url:11v6jhbk], it is likely referring to an ingredient containing Dextrin Palmitate, which is often used as a thickener or texturizer in various formulations, including powder cosmetics, to help with binding and improving texture.
In developing a pressed powder foundation with sunscreen formula, you should consider the main components:
- Oil Absorbers/Texturizers: Help control oil, make the skin look smooth, and improve powder adherence, such as Talc, Mica, Silica, Boron Nitride, Starch derivatives.
- Pigments: For coverage and evening out skin tone, mainly Iron Oxides (Yellow, Red, Black) and Titanium Dioxide are used.
- Sunscreen Agents (UV Filters): Can be Physical Sunscreens like Titanium Dioxide (which also acts as a pigment) or Zinc Oxide.
- Binders: Help the powder ingredients adhere together and press well, such as Zinc Stearate, Magnesium Stearate, Dimethicone, Silicones, Esters, or the Dextrin Palmitate group mentioned.
- Skin Conditioners/Emollients: Help prevent the powder from feeling dry, make it easy to blend, and provide a comfortable feel on the skin, such as Squalane, Jojoba Oil, Caprylic/Capric Triglyceride, or Silicone oils.
- Other Ingredients: Such as Preservatives, Antioxidants, or natural extracts to add special properties.
Dextrin Palmitate (as in Oil Thick™ Hard) can function as a Binder or Texturizer to help the powder adhere well and provide a smoother feel, which is an important part of making pressed powder.
To achieve the most suitable formula, you should consider selecting each ingredient based on the desired properties. For example, if high coverage is needed, you might increase the amount of pigments and choose types of Talc or Silica with soft-focus properties to blur pores. For long-lasting wear, you might focus on using Silicone-coated powders or Binders that enhance adhesion.
However, developing cosmetic formulas, especially pressed powder, requires experimentation to adjust the proportions of various ingredients to achieve the desired texture, binding, pressing quality, and other properties.
