Novel carboxylic acid derivatives for cosmetic compositions 
US Patent Application 20110124726 
Publication date: May 26, 2011
Assignee: DSM IP Assets B.V.

This patent discloses novel arylalkyl carboxylic acid derivatives, more specifically, with acylates of arylalkyl carboxylic acids with naturally occurring, nontoxic hydroxyl, sulfhydryl, amino or imino compounds, and to compositions containing them. The compositions are preferably cosmetic preparations and can also contain usual cosmetic adjuvants and additives, such as: preservatives/antioxidants, fatty substances/oils, water, organic solvents, silicones, thickeners, softeners, emulsifiers, sunscreens, cosmetic actives, antifoaming agents, moisturizers, fragrances, surfactants, pigments or nanopigments such as those suited for providing a photoprotective effect by blocking UV radiation, etc.

Method for producing vitamin D in a person
US Patent Application 20110123469
Publication date: May 26, 2011
Assignee: Topical Technologies, Inc.

This invention describes a method for enhancing the production of vitamin D within an individual's skin and includes a source of vitamin D, a sunlight exposure indicator and a sunscreen. Vitamin D, for example, cod liver oil, is applied to the skin topically via a patch or towelette or ingested orally. The exposure indicator is worn by the user and changes its state to indicate that the person has been exposed to sunlight for a predetermined period of time. The user preferably waits a sufficient time for the vitamin D to be absorbed into the skin, then exposes his or her skin to direct sunlight, and monitors the exposure indicator to determine if it has changed state. The user then applies the sunscreen to his/her skin after the exposure indicator changes state.
