Formulating Sunscreen CC Cream SPF50 PA+++ (Similar to Cathy Doll Speed White)
Question
I would like to ask the staff how to formulate a sunscreen CC cream that has properties similar to CATHY DOLL SPEED WHITE CC CREAM SPF50 PA+++. I need recommendations on the ingredients required, specifically for achieving SPF50 PA+++ and the "Speed White" effect.
Answer
Creating a Sunscreen CC Cream
Creating a product exactly like a specific commercial CC cream with SPF can be complex, as it involves specific formulations, ingredient combinations, and testing to achieve the desired texture, coverage, and sun protection factor (SPF) and PA rating.
However, you can formulate a similar type of product, a sunscreen CC cream, by combining a suitable cream base with sunscreen agents and color-correcting/whitening ingredients.
Key components typically include:
- Cream Base: A stable emulsion (oil-in-water or water-in-oil) that provides the desired texture and feel.
- Sunscreen Agents: These can be chemical filters that absorb UV radiation or physical blockers like Titanium Dioxide and Zinc Oxide that reflect and scatter UV radiation.
- Color Correcting / Whitening Ingredients: Pigments to correct skin tone and provide coverage, and potentially ingredients that offer a whitening effect.
Based on our search, SI01-2-TIO2 CR50 is a relevant ingredient. This is a form of Titanium Dioxide, which serves a dual purpose in a product like this:
- Sun Protection: It acts as a physical UV filter, helping to block both UVA and UVB rays, contributing to the SPF and PA rating.
- Whitening/Coverage: As a white pigment, it contributes to the "white" aspect of a "Speed White" product and provides coverage for skin imperfections.
To formulate a sunscreen CC cream, you would need to:
- Select a suitable base formulation.
- Incorporate sunscreen agents like SI01-2-TIO2 CR50 at appropriate usage rates (refer to the ingredient's recommended usage). You may need a combination of filters to achieve high SPF and PA.
- Add pigments (like iron oxides) to match skin tone and provide color correction and coverage.
- Include other beneficial ingredients like moisturizers, antioxidants, and texture enhancers.
- Crucially, achieving a specific SPF and PA rating requires laboratory testing of the final formulation. Simply adding sunscreen ingredients does not guarantee a specific level of protection.
Formulating cosmetics requires careful consideration of ingredient compatibility, stability, and safety. It's recommended to start with established base formulas and gradually incorporate active ingredients.
