Description

[0001]Composition comprising UV filters Technical field of the inventionThe present invention relates to UV filter compositions. More specifically thepresent invention relates to compositions comprising UV filters. Background of the invention UV radiation (sunlight and artificial) comprises three bands namely UVA, UVB, and UVC. Human skin is first and main defense line against UV radiationsemanating from the sun. The skin acts as a barrier against solar radiations andthereby tries to provide protection to the body from sunburns and imminent riskof skin cancer. However, this barrier does not provide total protection and asignificant part of the UV radiations, on exposure, penetrate into different layersof the skin. Use of sunscreen products containing UV filters with improved sunprotection factor (SPF) is a good way to protect the skin. However, certain UVfilters are absorbed through the skin resulting in systemic exposure withunknown consequences and also, using UV filters as such in sunscreenproducts do not show desired SPF.There are several prior art disclosures of compositions comprising UV filterswhich are either emulsified using suitable emulsifier systems (CN 112972283A) or encapsulated using suitable shells (WO2023137532A1). Encapsulation ofUV filters is preferred in industries as it improves the stability of UV filters,controls the exposure on skin, and also helps to minimize the penetration of UVfilters in the skin. US2007086962A1 discloses a stable sunscreen composition comprising: (i) an organic UV-A sunscreen; (ii) an organic UV-B sunscreen; and (iii) cosmetically acceptable vehicle in solid lipid encapsulate. However, said UV-A sunscreen and UV-B sunscreen are kept isolated from each other by encapsulating one of said sunscreens in solid-lipid encapsulate. This increases the number of steps involved in the process thereby leading to increase in the process cost.EP3628304A1, WO2019115621A1, WO2021175583A1, and EP3677244A2disclose multilamellar vesicles and lipid nanoparticles which encapsulate active ingredients such as triglyceride oils, fragrances etc., However, compositionsdisclosed in these prior art documents have not been explored for encapsulationof more than one active, specifically UV filters. There is thus, an unmet need to provide sunscreen compositions having highSPF and comprising more than two UV filters, having good stability, improveddispersion and providing protection across the entire UV spectrum. Further, thecomposition needs to be compatible with excipients as well as have goodsensory characteristics and should be easy to formulate.The Applicants have surprisingly found that encapsulating the UV filters canprovide higher SPF across a broad UV spectrum and improve the stability of the composition. The composition is highly effective even at low concentrations ofthe UV filters due to a higher loading of the UV filters during encapsulation.Accordingly in one aspect, the present invention provides a compositioncomprising at least three UV filters. Advantageously, the composition is stableand has high Sun Protection Factor (SPF). In another aspect, the present invention provides a process for the preparationof the composition comprising the UV filters.In yet another aspect, the present invention provides cosmetic formulations, preferably sunscreen formulations comprising the composition comprising at least three UV filters.In the present application, including in all embodiments of all aspects of thepresent invention, the following definitions apply unless specifically stated otherwise. Unless otherwise stated, all percentages are by weight (w / w) of the respective component or the total composition, respectively. “wt.-%” means percentage by weight; “vol.-%” means percentage by volume; “mol-%” means percentage by mole. Unless otherwise stated, all ratios are weight ratios (weight per weight). Preferably, references to ‘parts’ e.g. a mixture of 1 part Xand 3 parts Y, is a ratio by weight. + / - indicates the standard deviation. Allranges are inclusive and combinable. Unless otherwise stated, allmeasurements are understood to be made at 23 °C and at ambient conditions,where “ambient conditions” means at approximately 1 atmosphere (atm) ofpressure and at about 50 % relative humidity. “Relative humidity” refers to theratio (stated as a percent) of the moisture content of air compared to thesaturated moisture level at the same temperature and pressure. Relativehumidity can be measured with a hygrometer, in particular with a probe hygrometer from VWR®International. Herein “min” means “minute” or“minutes”. Herein “mol” means mole. Herein “g” following a number means“gram” or “grams”. “Ex.” means “example”. Herein, “q.s.” and “Q.S.” meansquantum sates, thus, as much as needed. In the context of contents, thisrefers to the mass to obtain 100 wt.-% as total. For instance, the water is filled up to obtain a sum of 100 wt.-% of all ingredients. In the context of the pH, “q.s.” means that the amount of acids and bases needed to obtain the desired pH is used. As used herein the term "comprising" is meant not to be limiting to any subsequently stated elements but rather to encompass non-specified elements of major or minor functional importance. In other words, the listed steps, elements or options need not be exhaustive. Whenever the words "including" or "having" are used, these terms are meant to be equivalent to "comprising" as defined above. Where the compositions of the subjectinvention are described as "including" or "comprising" specific components or materials, narrower embodiments where the compositions can "consist essentially of" or "consist of" the recited components or materials are also contemplated.“Derivatives” includes but is not limited to, amide, ether, ester, amino,carboxyl, acetyl, acid, salt and / or alcohol derivatives of a given compound.In at least one embodiment, “derivatives thereof” means the amide, ether,ester, amino, carboxyl, acetyl, acid, salt and alcohol derivatives.“Cosmetically acceptable” may be understood in the broadest sense in that the compositions or components described are suitable for use in contact with human keratinous tissue without undue toxicity, incompatibility, instability, allergic response, and the like. All compositions described herein which have the purpose of being directly applied to keratinous tissue are cosmetically acceptable.Accordingly in a first aspect, the present invention provides a UV filtercomposition comprising:a) one or more surfactants having a HLB value of greater than 6,b) at least three UV filters,c) a carrier,d) optionally a co-surfactant, ande) an aqueous phase.Preferably, the loading of the said UV filters is from 10 to 60% by weight of thetotal composition. The loading of the said UV filters is more preferably from 15to 55% or from 20 to 60%, even more preferably from 20 to 55%, particularlypreferably from 25 to 50%, by weight of the total composition.Advantageously, the UV filter composition of the present invention has verygood stability and shows no phase separation over a period of time.The one or more surfactants a) are characterized by their HLB value of morethan 6. The nature of a surfactant is represented by the hydrophilic-lipophilic balance of the molecule. The degree of this hydrophilic-lipophilic balance can be determined by calculating values for the different regions of the molecule, as described by Griffin in 1949 and 1954. Griffin's method has been primarily developed for non-ionic surfactants as described in 1954 works as follows where Mh is the molecular mass of the hydrophilic portion of the molecule, and M is the molecular mass of the whole molecule, giving a result on a scale of 0 to 20. An HLB value of 0 corresponds to a completely lipophilic molecule, and a value of 20 corresponds to a completely hydrophilic molecule. The term “HLB” as used in this specification for nonionic surfactants is calculated by the above formula. The method of Griffin is published, for example, in Journal of the Society of Cosmetic Chemists, 5 (4), 249-256 (1954). The term “HLB” as used in this specification for anionic, cationic or amphotericsurfactants is calculated by the method of Davies. This method is published,for example, in Gas / Liquid and Liquid / Liquid Interfaces. Proceedings of 2ndInternational Congress Surface Activity, pp.426-438, Butterworths, London1957.
