Polyglycerol esters of natural oils fatty acids, which can be from a large variety of sources, e.g., olives, and of castor seed, which can be, e.g., polyricinoleic acid, which have water-in-oil emulsifier properties, processes of preparing the above compounds having water-in-oil emulsifier properties and the use of these polyglycerol esters as water-in-oil emulsifiers and/or dispersing agents for cosmetic, skin care and pharmaceutical formulations.

Water-in-oil emulsifier derived from natural sources

The present disclosure relates, according to some embodiments, to photostable photoactive compositions comprising (a) at least one photoactive compound that develops within itself an excited state energy when subjected to UV radiation and (b) a block copolymer comprising a plurality of blocks, wherein the block copolymer is operable to quench the excited state energy.

Photostable compositions comprising para-alkoxyl phenyl substituted propenoic acid (APP) copolymer derivatives

The present disclosure relates, according to some embodiments, to a method of determining a quantitatively measured photoprotection of a photoprotective composition, the method comprising: (a) distributing the photoprotective composition in a position in between a drawdown bar and at least one substrate to produce a distributed photoprotective composition; (b) drawing down the distributed photoprotective composition to a thickness on at least one substrate to produce a drawn down sample film; (c) drying the drawn down sample film to produce a dried sample film; (d) measuring a UV absorption of the dried sample film to produce a UV absorption spectrum; (e) determining the quantitatively measured photoprotection of the photoprotective composition from the UV absorption spectrum.

Methods and systems for quantitatively measuring photoprotection

This disclosure is directed to devices, systems, and methods for skin damage protection and detection, including providing images and recommendations and images to users to assist them with proper application of an applied-to-skin sunscreen. Disclosed devices include personal user devices that are operable to emit ultraviolet light and to measure the degree of ultraviolet light reflected from skin, upon which images can be presented on a device screen to give visual indications of sunscreen coverage and/or skin aging. Measured ultraviolet images and visible light images can further be presented to device users in an overlay, side-by-side, or other fashion, to further assist in detection of sunscreen coverage and/or degrees of skin damage. Further, the user of the device may be able to view real-time video in the same ultraviolet/visible light overlay fashion, and assess the state of photo-protective effects of an applied-to-skin sunscreen.

Protection and skin damage detection devices and system

A method of quenching excited state energy from a photodegradable pigment that has been excited by absorption of light having a wavelength in the wavelength range of 290-800 nm, comprising reacting a pigment with a conjugated fused tricyclic compound having electron withdrawing groups of Formula (II) or a salt thereof:  

Method of quenching singlet and triplet excited states of photodegradable pigments, such as porphyrin compounds, particularly protoporphyrin IX, with conjugated fused tricyclic compounds having electron withdrawing groups, to reduce generation of singlet oxygen

The present disclosure relates, according to some embodiments, to molecules, including conjugated fused polycyclic molecules, that may receive excited state energy from other molecules (e.g., light-absorbing molecules) or directly from the irradiation sources. According to some embodiments, the disclosure relates to molecules, including conjugated fused polycyclic molecules, that may resolve (e.g., quench, dissipate) excited state energy, normally by way of releasing it as heat. (e.g., as heat). Conjugated fused polycyclic molecules of various structures are disclosed including Formula III:  The disclosure further relates to methods of use and/or therapy using molecules of Formulas I, II, and/or III.

Compositions, apparatus, systems, and methods for resolving electronic excited states

A method of quenching excited state energy from a pigment that has been excited by absorption of light having a wavelength in the wavelength range of 290-800 nm, comprising reacting a pigment with a conjugated fused tricyclic compound having electron withdrawing groups:  and 

Method of quenching singlet and triplet excited states of pigments, such as porphyrin compounds, particularly protoporphyrin IX, with conjugated fused tricyclic compounds have electron withdrawing groups, to reduce generation of reactive oxygen species, particularly singlet oxygen

The present disclosure relates, according to some embodiments, to molecules, including substituted propenoic amides (e.g., aryl substituted propenoic amides), that may receive excited state energy from light-absorbing molecules. According to some embodiments, the present disclosure relates to molecules, including substituted propenoic amides (e.g., aryl substituted propenoic amides), that may quench, dissipate, and/or otherwise resolve excited state energy (e.g., as heat).
