Patents by Inventor Charu Duggal

Charu Duggal has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.
    Type: Grant
    Filed: July 2, 2013
    Date of Patent: March 29, 2016
    Assignee: Conopco, Inc.

  • Patent number: 9034304
    Abstract: The invention relates to a high SPF sunscreen composition. There is a problem of achieving high SPF while keeping the total amount of sunscreens in the compositions relatively low. It is desirable, that the enhanced SPF benefit could be achieved through synergistic interaction of commonly used ingredients, thereby the present applicants have been working on solving this problem and have surprisingly found that cosmetic compositions comprising dibenzoylmethane or its derivative in combination with an oil soluble UV-B sunscreen when incorporated in a sunscreen composition along with a non-ionic surfactant of a select class meeting certain HLB requirements, provide the enhanced SPF benefits when applied on the substrate of interest.

  • 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: 20130266527
    Abstract: The invention relates to a high SPF sunscreen composition. There exists a need for a personal care composition comprising sunscreen agents in low concentrations that are able to provide much higher SPF as compared to known sunscreen compositions comprising such low levels of sunscreen agents. The present applicants have been working on solving this problem and have surprisingly found that cosmetic compositions comprising dibenzoylmethane or its derivative in combination with an oil soluble UV-B sunscreen when incorporated in a sunscreen composition along with a non-ionic surfactant of a select class meeting certain HLB requirements, provide the enhanced SPF benefits when applied on the substrate of interest.

  • 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.

  • Publication number: 20130004440
    Abstract: The present invention relates to photostable sunscreen compositions comprising sunscreens, more particularly to a liquid composition in emulsion or microemulsion format comprising dibenzoylmethane sunscreens. An object of the present invention is to provide photostable compositions comprising dibenzoylmethane sunscreens, wherein the stabilization is brought about by using readily available and inexpensive ingredients. The present inventors have surprisingly found that cosmetic compositions comprising dibenzoylmethane or its derivative can be stabilized in a specific liquid emulsion or microemulsion formulation having specified ingredients in selective amounts.
