`
`BACKGROUND
`
`Various natural personal care compositions (i.e. personal
`care compositions which are formed from natural ingredi-
`ents) have been shown to lack robustness against microbial
`attack. In order to address this issue, anhydrous products
`have been developed. As these products are anhydrous, they
`do not support microbial growth and are therefore micro-
`robust. However, anhydrous base formulations (which con-
`tain mainly oils and waxes) tend to be very greasy and to
`have a “heavy” skin feel, which some consumersfind to be
`undesirable. In the case of anhydrous compositions which
`contain certain metal oxides, e.g. zinc oxide or titantum
`oxide, the compositions can also leave a white residue on the
`skin following application. Again, some consumersalso find
`this “whitening”effect to be undesirable. It would therefore
`be desirable to provide a natural personal care composition
`whichis micro-robust and whichis non-greasy. It would also
`be desirable to provide such a composition which does not
`leave a white residue on the skin following application.It
`would also be desirable for such compositions to be physi-
`cally stable at high and low temperatures.
`
`BRIEF SUMMARY
`
`In one aspect, an anhydrous personal care composition,
`comprising: (a) at least one ester, wherein said at least one
`ester is selected from one or more of the following groups:
`(i) triglycerides, (ii) diglycerides, (111) monoglycerides, (iv)
`monoesters of diols, and (v) diesters of diols, and wherein a
`total concentration of said at least one ester is 45 to 60
`
`weight %, based on the total weight of the composition; (b)
`a first wax having a melting point of 35° C. to 72° C. present
`in an amount of 5 to 25 weight %, based on the total weight
`of the composition; (c) a second wax having a melting point
`of 73° C. to 90° C. present in an amount of 0.5 to 15 weight
`% based on the total weight of the composition; (d) at least
`oneplant oil having a saponification value of 150 to 275 mg
`KOH/g, wherein a total concentration of said at least one

`the foregoing formulation are separate components which
`are combined to provide the composition described. For
`example, the “at least one ester” would not be considered
`part of the plant oil or the waxes, anyester that is part of the
`waxesor plant oils would not be considered part of the “at
`least one ester”, and any wax that is part of the plant oil

`perature, e.g., having a melting point between 35° C. and 90°

`
`Further areas of applicability of the present invention will
`become apparent from the detailed description provided
`hereinafter. It should be understoodthat the detailed descrip-
`tion and specific examples, while indicating the preferred
`embodimentof the invention, are intended for purposes of
`illustration only and are not intendedto limit the scope of the
`invention.
`
`DETAILED DESCRIPTION
`
`The following description of the preferred embodiment(s)
`is merely exemplary in nature and is in no way intended to
`limit the invention, its application, or uses.
`As used throughout, ranges are used as shorthand for
`describing each and every value that is within the range. Any
`value within the range can be selected as the terminus of the
`range. In addition, all references cited herein are hereby
`incorporated by referencedin their entireties. In the event of
`a conflict in a definition in the present disclosure and that of
`a cited reference, the present disclosure controls.
`Unless otherwise specified, all percentages and amounts
`expressed herein and elsewhere in the specification should
`be understood to refer to percentages by weight. The
`amounts given are based on the active weight of the mate-
`rial.
`Unless otherwise specified, all experiments described
`herein are conducted at 25° C. and at atmospheric pressure.
`As used herein, the term “anhydrous composition” indi-
`cates that the composition contains 2 weight % or less free
`water. In other embodiments, the maximum amountof water
`is 1.5 weight %,
`1 weight %, or 0.5 weight %. In certain
`embodiments, there is no free water. When calculating the
`water content, water molecules that are part of a hydrate of
`a material are not counted.
`As used herein, the term “natural composition” indicates
`that the composition is formulated from ingredients which
`are extracted from the earth or sea, derived from plants, or
`synthesized by other organisms. Similarly, the term “natural
`ingredients” as used herein indicates ingredients which are
`extracted from the earth or sea, derived from plants, or
`synthesized by other organisms.
`
`

`As used herein, the “saponification value” (SAP value) of
`an oil
`is the number of milligrams (mg) of potassium
`hydroxide (KOH) which is required to saponify 1 g of the
`oil.
`
`As discussed above, personal care compositions formu-
`lated from natural ingredients may be formulated so as to be
`anhydrous in order to ensure micro-robustness in the pack-
`age and during consumer use. However, such anhydrous
`compositions have previously been found to have a heavy
`and greasy feel, which some consumers find undesirable.It
`would therefore be desirable to provide a natural personal
`care composition which is micro-robust and which is non-
`greasy.
`Anhydrous compositions which contain certain metal
`oxides, e.g. zinc oxide or titanium oxide, can leave a white
`residue on the skin following application. Consumers may
`also find this “whitening” effect to be undesirable. It would
`therefore be desirable to provide a natural personal care
`composition which is micro-robust and non-greasy, and in
`which the amount of white residue left on the skin following
`application is minimized.
`Tt would also be desirable to provide a natural personal
`care composition which is micro-robust and non-greasy, and
`which does not leave a white residue on the skin following
`application, which is also physically stable at high and low
`temperatures (e.g. which does not exhibit separation into a
`bulk solid phase and a bulk liquid phase at high and low
`temperatures). It would also be desirable to formulate such
`compositions from all-natural ingredients (i.e. “100% natu-
`ral” compositions).
`Therefore, in one aspect, there is provided an anhydrous
`personal care composition, comprising: (a) at least one ester,
`wherein said at least one ester is selected from one or more
`
`of the following groups: (i) triglycerides, (11) diglycerides,
`(111) monoglycerides,
`(iv) monoesters of diols, and (v)
`diesters of diols, and wherein a total concentrationof said at
`least one ester is 45 to 60 weight %, based on the total
`weight of the composition; (b) a first wax having a melting
`point of 35° C. to 72° C. present in an amount of 5 to 25
`weight %, based on the total weight of the composition; (c)
`a second wax having a melting point of 73° C. to 90° C.
`present in an amount of 0.5 to 15 weight % based onthetotal
`weight of the composition; (d) at least one plant oil having
`a saponification value of 150 to 275 mg KOH/g, wherein a
`total concentration of said at least one plant oil is from 5 to
`35 weight %, based on the total weight of the composition.
`The present inventors have surprisingly found that,
`in
`addition to having good micro-robustness, such composi-
`tions have reduced greasiness and an improved after-feel
`(such as reduced tackiness and drag) on the skin as com-
`pared to other anhydrous compositions. Such compositions
`are also physically stable at high and low temperatures.
`The present inventors have also surprisingly found that
`the amount of white residue remaining on the skin following
`application of the composition is reduced when the compo-
`sitions comprise a first wax having a melting point of 35° C.
`to 72° C., and a second wax having melting point of 73° C.
`to 90° C.
`
`The present inventors have also surprisingly found that
`such compositions are also physically stable G.e. do not
`exhibit separation into a bulk solid portion and a bulk liquid
`portion) when stored at 49° C./0% relative humidity for a
`period of 13 weeks, and whenstored at 40° C./75% relative
`humidity for a period of 13 weeks, and show acceptable
`dispensing characteristics in addition to being non-greasy.
