RiceSorb™ and LipidSoft™ in Sunscreen Formulations

Regarding your question about using RiceSorb™ in a sunscreen formulation where LipidSoft™ is used as a solvent for sunscreen agents, and whether RiceSorb™ will absorb LipidSoft™ and reduce its oil-absorbing effectiveness on the skin:

RiceSorb™ is a rice starch designed to absorb oil. When incorporated into a formulation containing oily components like LipidSoft™, RiceSorb™ will indeed absorb some of these oils from the formula itself. This absorption helps to modify the texture of the product, potentially making it feel less oily or more matte.

However, as confirmed by the expert, this absorption of internal oils does not prevent RiceSorb™ from absorbing oil (sebum) from the skin after application. The primary function of RiceSorb™ is to control oiliness, and it will continue to perform this function on the skin.

In summary, while RiceSorb™ will absorb LipidSoft™ within the formula, its overall ability to reduce oiliness, whether from the product or the skin, remains effective. The absorption of internal oils contributes to the desired texture and feel of the formulation while the ingredient still works to absorb excess sebum on the skin surface.
