Types of UV filters

Chemical vs Physical - Advantages • Chemical – Well understood by formulators. – Low concentrations can give good efficacy. – Good skin feel with no powdery appearance. • Physical – Broad spectrum and photo-stable. – Safe and low irritancy. – No need to use more than one active to gain high SPF. – Once dispersed are easy to incorporate into finished product.

Chemical vs Physical - Disadvantages • Chemical – Most are narrow spectrum and some are not photostable. – Usually need to mix to get broad spectrum and high SPF. – Questions over irritancy and impact on environment. • Physical – Can be difficult to formulate with if not pre -dispersed. – Can leave skin appearing white and if not formulated carefully give poor skin feel. – Questions over nano particles, do they absorb into skin?

Common Problems in Sunscreens

Concerns & Inconvinience of Sunscreens • Tend to feel oily, sticky and heavy Ø Oil type formulation, especially the high SPF products. • Chemical sunscreens can cause skin irritation Ø Especially to skin-sensitive people. • Chemical sunscreens can penetrate the skin Ø Oil type formulation helps penetration. • Normally need to reapply every two hours Ø Need to reapply when sun protection ability reduce to below 70 %.

Concerns & Inconvinience of Sunscreens • Difficult to wash off Ø Oil type formulation usually difficult to wash off by surfactants. • Selection and storage of multiple sunscreen APIs Ø Combination of multiple APIs to achieve broad spectrum protection. Ø The chosen APIs has to compatible with other raw materials. Ø Have to stock several APIs for different formulation. • Limited O/W formulation type Ø O/W formulation leads to oily and sticky, uncomfortable to wear.

Concerns & Inconvinience of Sunscreens • Not easy to stabilize the emulsifying system Ø APIs has to emulsify, including liquid and solid APIs & stability of emulsifying system related to the stability of end product. • Guesswork needed to achieve desired SPF Ø The usage of APIs usually is not linear relation with SPF. Ø Increasing API usage sometimes will not increase SPF, even will reduce SPF. Ø To spend a very long time to design and test the efficiency of the formulation

Concerns & Inconvinience of Sunscreens • Excess sunscreen APIs used The highest SPF usually is when the formulation finished. Excess usage of APIs to provide a safety margin for the SPF. • Aggregation of sunscreen APIs

Aggregation & Absorption

Sun. Cat Encapsulation

Unique Technology • Pre-solubilized mixture of both liquid and powder chemical sunscreen • Through a proprietary, high pressure, and high shear process • Micronized sunscreen enwrapped in doublelayered sphere • Negatively charged outer sphere • Prevent aggregation

Formulating with Sun. Cat Advantages • • • No need to solubilize before adding No need to use additional emulsifiers Negligible effect on viscosity of product No need to use complicated UV filter blend Easy to work out requirements for given SPF Low usage compared to other similar products • Low cost in use compared to other similar products • Easily added
