Embodiment Construction

[0016] This application relates to adaptive polymers, and, more particularly, to adaptive polymers for use in anhydrous sunscreen formulations. In another aspect of the invention, the present application also relates to sunscreen compositions or other compositions requiring a specific SPF value, wherein the composition contains a polymer that increases the SPF of the composition.

[0017] The sunscreen compositions disclosed herein contain relatively hydrophilic polymers that become hydrophobic upon exposure to water and / or perspiration thereby rendering the compositions water resistant. Since the adaptive polymer becomes hydrophobic when in contact with water, products developed with this polymer can be used at home and at the same time at the beach or at events.

[0018] This property is difficult to predict based on the structure of the polymer alone. Several factors may contribute to polymers exhibiting such properties. Some of these factors are as follows:

Abstract

Compositions comprising sun-care actives and self adapting polymers are disclosed. Self adapting polymers align themselves with the hydrophilic group pointing to the surface during application thus delivering an aesthetically pleasing surface to the consumers with a pleasant after feel. These polymers then rearrange upon contact with water so that the hydrophobic groups now point to the surface which then increases the water resistance of the formulation.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 301,469, filed February 4, 2010, and US Provisional Application No. 61 / 301,453, filed February 4, 2010, the entire contents of which applications are incorporated herein by reference. technical field [0003] The present application describes adaptive polymers and sunscreen compositions comprising adaptive polymers that become more hydrophobic when exposed to water. The present application also relates to SPF products exhibiting increased SPF values, and more particularly to SPF formulations containing SPF increasing polymers in compositions. According to one aspect, the composition may be a product for topical application on the hair or skin to protect against UV damage. The product may contain one or more sunscreens in an amount sufficient to increase the SPF level of the polymers described herein. Background technique [0004] Sunscreen compo...
