Adjusting Sunscreen Texture

You have a good base formula using SPF Protect Ultra™ II, Milk Lotion Maker™, Satin Cream Maker™, Water, and Mild Preserved Eco™. You're aiming for a thinner, more milky texture similar to Anessa and are asking if increasing Milk Lotion Maker™ will help.

Based on the properties of the emulsifiers:

• Milk Lotion Maker™: This emulsifier is designed to create a liquid, easy-to-spread texture like a milky lotion and can handle high oil loads (up to 40%). However, the description also states that using a larger proportion will thicken the formula.
• Satin Cream Maker™: This is a heat-free emulsifier and thickener that creates a soft and smooth cream texture. Increasing its percentage is specifically noted as a way to achieve a thicker cream.

Your current formula uses 3% Milk Lotion Maker™ and 0.7% Satin Cream Maker™ with 15% SPF Protect Ultra™ II. This combination, as you observed, results in a texture that is likely thicker than a milky lotion.

Increasing Milk Lotion Maker™ might not give you the thinner texture you desire, as its description indicates it can thicken at higher concentrations. To achieve a thinner, more milky consistency, you might need to adjust the emulsifier system differently.

Consider the following:

1. Reduce Satin Cream Maker™: Since Satin Cream Maker™ acts as a thickener, reducing its percentage could help decrease the overall viscosity and make the formula more fluid.
2. Adjust Emulsifier Ratio: Experiment with the ratio of Milk Lotion Maker™ and Satin Cream Maker™. You might need a higher proportion of Milk Lotion Maker™ relative to Satin Cream Maker™, or potentially reduce the total amount of emulsifiers, while ensuring stability.
3. Review Oil Phase: The sample formula for SPF Protect Ultra™ II at 15% uses 3% Milk Lotion Maker™ and 0.7% Satin Cream Maker™. If you want a significantly thinner texture, you might need to re-evaluate the entire emulsifier system or the oil phase composition, although changing the oil phase (SPF Protect Ultra™ II) would affect the SPF level.

Achieving a texture identical to a specific commercial product like Anessa can be challenging as it involves the precise combination and ratio of all ingredients, including emollients and texture enhancers not present in your current basic formula. However, adjusting the emulsifier system, particularly reducing the thickener (Satin Cream Maker™), is the most direct way to attempt to thin the formula.

Always make small adjustments and test the stability of the formula after any changes.
