How to Formulate Water Break Sunscreen
คำถาม
How can I formulate a sunscreen with a "water break" texture (Macro emulsion)? I'm looking for guidance on the key ingredients needed to create this texture, suitable sunscreen agents that are compatible with this type of formulation (like Water-in-Silicone or silicone-free versions), and general tips for developing such a formula, especially considering the need for water-dispersible sunscreen filters.

How to Make Water Break Sunscreen
I understand that attempting to formulate yourself after a negative experience can be challenging. Water break cream, technically known as a Macro emulsion, is a formulation with specific techniques.
Achieving the "water break" texture that releases water droplets upon application typically involves using ingredients that create a special structure within the cream. This structure breaks upon rubbing or contact, releasing the trapped water droplets.
My tools cannot provide complete formulas with exact percentages directly, but they can offer information about key ingredients used to create this texture and compatible sunscreen agents.
Ingredients for Creating Water Break Texture
There are specific ingredients designed to help create the water break texture, such as:
- WaterBreaker™: This is a silicone emulsifier that helps create a Water-in-Silicone water break cream. When applied to the skin, it forms a large number of water droplets. Mixing must be done gently, avoiding high speed or a homogenizer.
- WaterDropper™: This is also an emulsifier that helps create a water break cream, but it is a silicone-free version. It's suitable for formulas where silicones are to be avoided. The mixing method is similar to WaterBreaker™, requiring slow mixing at low speed.
Suitable Sunscreen Agents
For sunscreen agents that can be used in this type of formula, it's best to choose types that disperse well in water to fit the structure of a water break formula. An example is the AquaForce™ series, which are highly stable, water-dispersible sunscreen filters, such as:
- AquaForce™ BEMT: Provides Broad spectrum UVA/UVB protection.
- AquaForce™ DHHB: Focuses on UVA protection and is compatible with physical sunscreens.
The AquaForce™ series sunscreen agents can be directly mixed into the water phase of the formula, making formulation easier.
Additionally, there is Clear Sprayable Sunscreen, a clear liquid SPF40 sunscreen base that might be adapted for use in this type of formula, but the desired texture characteristics should be considered.
Additional Recommendations
Developing a water break formula requires experimentation and adjusting proportions to achieve the desired texture and stability. It's important to study the usage information for each ingredient in detail.
And as the staff recommended, please check the forum thread topic6167.html. Other members may have asked about or shared their experiences with this type of formula there.
I hope this information is helpful for getting started. If you have more questions about these ingredients, feel free to ask!
