  • Patent number: 10143642
    Abstract: The present invention relates to a broad spectrum stable sunscreen molecule having the general structure (Formula) where “X” is an organic sunscreen belonging to the UVA class and “Y” is an organic sunscreen belonging to UVB class or vice-versa. The invention also relates to a stable sunscreen composition comprising the inventive sunscreen molecule, a UV-B organic sunscreen and a cosmetically acceptable base. The invention also relates to a method of providing UV protection to the sun-exposed parts of human or animal body comprising the step of applying the above composition.
    Type: Grant
    Filed: December 11, 2014
    Date of Patent: December 4, 2018
    Assignee: Conopco, Inc.

  • Patent number: 9539189
    Abstract: The invention relates to a photoprotective personal care composition that provides enhanced stability of the UV-A sunscreen present therein. The present inventors have found that it is possible to enhance stability of the UV-A sunscreen of the dibenzoylmethane group by including certain compounds of the chalcone group.

  • Patent number: 9295625
    Abstract: The invention relates to a photostable sunscreen composition that not only provides enhanced sun protection by way of high SPF, but does that over sustained period of time after applying the composition on the skin. The present inventors have found that when a compound of the triazine group is used without additional UVA or UVB sunscreen, and a non-ionic surfactant is included in a cosmetic base comprising fatty acids, it is possible to achieve high SPF.

  • Patent number: 8940343
    Abstract: The present invention relates to a personal care composition. More particularly the present invention relates to stabilization of UVA sunscreen dibenzoylmethane derivatives or even more particularly Parsol 1789™ (4-t-butyl-4?-methoxydibenzoylmethane) in personal care compositions. It is an object of the present invention to provide a personal care composition with relatively long photoprotection efficiency. It is another object of the present invention to stabilize Parsol 1789 by use of a natural substance or materials derived from plants. Surprisingly the present inventors have found that theaflavin or black tea extract having high levels of theaflavin, can act as a photostabilizer for dibenzoylmethane derivatives or Parsol-1789™.

  • Publication number: 20140134118
    Abstract: The invention relates to a sunscreen composition. It is an object of the present invention to provide high SPF photo-protective sunscreen compositions while ensuring prolonged efficacy of the UV-A sunscreen used therein while using relatively low amounts of sunscreen agents thereby keeping costs low.

  • Publication number: 20130251653
    Abstract: The present invention relates to a personal care composition, particularly, a stable sunscreen composition. The problem associated with a dibenzoylmethane sunscreen is its relatively unstable nature, especially in the presence of a UV-B sun-screen. There is a need for using more readily and easily available compound as a sunscreen stabilizer thereby ensuring reduced cost of such sunscreen compositions. The present inventors have worked intensively on solving this problem and found that a derivative of an active (gingerol) found in ginger i.e. zingerone, provides for such improved stability.

  • Publication number: 20130189204
    Abstract: The invention relates to a high SPF/UVAPF sunscreen composition. It is an object of the present invention to provide a high SPF (equal to or greater than 15) or high UVAPF (equal to or higher than 4) photo-protective sunscreen composition without compromising on the desired skin sensorial properties while using relatively low amounts of sunscreen agents thereby keeping costs low.
