DETAILED DESCRIPTION
Unless otherwise specified “a” or “an” means one or more.
As used herein, the term “about” placed before a specific numeric value may mean ±20% of the numeric value; ±18% of the numeric value, ±15% of the numeric value; ±12% of the numeric value; ±8% of the numeric value; ±5% of the numeric value; ±3% of the numeric value; ±2% of the numeric value; ±1% of the numeric value or ±0.5% of the numeric value.
All content information for ingredients of compositions expressed as percent (%) refers to percent (%) by mass, relative to the total mass of the composition, unless specified otherwise.
As used herein, the expression “water-in-oil composition” and related expressions refers to an water-in-oil type emulsified composition in which an aqueous (water) phase is dispersed in an oil phase.
As used herein, the expression “microplastic particles” refers to particles containing a solid polymer, to which additives or other substances may have been added, and where > 1% w/w of particles have (i) all dimensions 0.1pm < x < 5mm, or (ii), for fibres, a length of 0.3 pm < x < 15mm and length to diameter ratio of >3.
The expression “particles containing a solid polymer” refers either (i) a particle of any composition with a continuous solid polymer surface coating of any thickness or (ii) particles of any composition with a solid polymer content of > 1% w/w.
1,4-di oxane and ethylene oxide impurities of polyethylene glycol (PEG)-containing surfactants may present concerns for satisfying “clean beauty” requirements, such as safety, non-toxicity and transparency in labeling, for cosmetic products.
Some consumers have also environmental concern about a low biodegradability of silicone. Many water-in-oil type emulsified cosmetic products use bentonite-gel systems with PEG- containing surfactants, silicone containing surfactants and/or silicone solvents, such as silicone oils, e.g. cyclomethicone (D5) and dimethicone. Eliminating PEG containing surfactants, silicone containing surfactants and/or silicone solvents can often negatively affect stability of cosmetic product and/or its sensorial properties.
In addition, many water-in-oil cosmetic compositions may have their oil phase separated over time and need therefore to be shaken up before the use. Furthermore, a color of stored water- in-oil cosmetic products may change due to pigment migration and agglomeration within a composition of the product.
The present disclosure provides a water-in-oil type emulsified composition, which may have improved stability. Specifically, the present composition may avoid oil phase separation over a period of at least one week, or at least two weeks, or at least three weeks or at least four weeks at room temperature, and/or at an elevated temperature such as 37°C, 45°C or 50°C, and/or a decreased temperature, such as 0°C or -5°C.
The present composition may also avoid color change due to pigment migration. The present composition may maintain sensory values, such as creaminess and ease of application. In many embodiments, the present composition may contain no PEG surfactant. In many embodiments, the present composition may contain to PEG based ingredients.
The composition may be a long wear composition. As used herein, the term “long wear” means that the composition may be worn for at least 4 hours up 24 hours or for at least 6 hours up to 24 hours or for at least 8 hours up to 24 hours or at least for at least 10 hours up to 24 hours or for at least 12 hours up to 24 hours or for at least 14 hours or for at least 16 hours or for at least 18 hours without interruption of esthetical appearance.

Silicone resin
The cosmetic composition may comprise at least one silicone resin which may be a solid or a liquid. In some embodiments, at least one silicone resin may be in the oil phase of the cosmetic composition. The term “silicone resin” may mean a multidimensional structure, such as, for example, a branched or a cage-like structure, with a basic backbone polymer structure comprising or made of alternating silicon and oxygen atoms.
Silicone resins, which are also known as siloxane resins, may be described using the "MDTQ" nomenclature, the resin being described as a function of the various siloxane monomer units it comprises, each of the letters "MDTQ" characterizing a type of unit.
The letter “M” represents a mono-functional unit of formula R1R.2R.3SiO, with the silicon atom being bonded to only one oxygen.
The letter “D” represents a di-functional unit RiIQSiCh in which the silicon atom is bonded to two oxygen atoms.
The letter “T” represents a trifunctional unit of formula RiSiCh, in which the silicon atom is bonded to three oxygen atoms.
The letter “Q” represents a quarto-functional unit of formula Si O4, in which the silicon atom is bonded to four oxygen atoms.
Such resins are described, for example, in the Encyclopedia of Polymer Science and Engineering, vol. 15, John Wiley and Sons, New York, (1989), pp. 265-270, and U.S. patents Nos. 2,676,182, 3,627,851, 3,772,247, 5,248,739, 5,082,706, 5,319,040, 5,302,685 and 4,935,484.
In the units M, D and T, Ri functional groups, i.e. Ri, R2 and R3, may be the same or different. Each of Ri, R2 and R3 may be, for example, a hydrocarbon-based radical, such as an alkyl group, containing from 1 to 10 carbon atoms, an aryl group, including a phenyl group, a phenylalkyl group or a hydroxyl group.
Various silicone resins with different properties may be obtained from various combinations of units, the properties of these polymers varying as a function of the type of monomer (or unit), the nature and number of the radical(s) Ri, the length of the polymer chain, the degree of branching and the size of the side chains. A silicone resin used in the composition may be, for example, of a silicone resin of MQ type, a silicone resin of T type, a silicone resin of MQT type or a combination thereof. The use of D unit may be optional. However, it may be preferred that a silicone resin, such as an MQT resin, does not contain any D unit(s). In some embodiments, the at least one silicone resin may comprise at least one MQT silicone resin, which may be for example, a phenyl modified MQT silicone resin (MQT-Ph resin).
In some embodiments, the silicone resin may be an MQ resin, such as, for example, trimethylsiloxysilicate.

Polar Oil
The term "polar oil" means any lipophilic (hydrophobic) compound having, at 25°C, a solubility parameter 5a characteristic of dispersive interactions of greater than 16 and a solubility parameter 6P characteristic of polar interactions of strictly greater than 0. The
solubility parameters 5a and 6P are defined according to the Hansen classification. For example, these polar oils may be chosen from esters, triglycerides and ethers.
The definition and calculation of the solubility parameters in the Hansen three-dimensional solubility space are described in the article by CM. Hansen: "The three dimensional solubility parameters", J. Paint Technol. 39, 105 (1967).
According to this Hansen space:
- 5D characterizes the London dispersion forces derived from the formation of dipoles induced during molecular impacts;
- 6P characterizes the Debye interaction forces between permanent dipoles and also the Keesom interaction forces between induced dipoles and permanent dipoles;
- 5h characterizes the specific interaction forces (such as hydrogen bonding, acid/base, donor/acceptor, etc.); and
- 5a is determined by the equation: 5a = (6P 2 + 5h2)1/2.
The parameters 5P, 5h, 5p and 5a are expressed in (J/cm3)1/2
The polar oil may be a volatile or non-volatile hydrocarbon-based, silicone and/or fluoro oil.
These oils may be of plant, mineral or synthetic origin.
The term "polar hydrocarbon-based oil" means an oil formed essentially from, or even constituted by, carbon and hydrogen atoms, and optionally oxygen and nitrogen atoms, and not containing any silicon or fluorine atoms. It may contain alcohol, ester, ether, carboxylic acid, amine and/or amide groups.
The term "silicone oil" means an oil containing at least one silicon atom, and especially containing Si-0 groups.
The term "fluoro oil" means an oil containing at least one fluorine atom.
The polar oil may have a surface tension of greater than 10 mN/m at 25°C and at atmospheric pressure.
The surface activity is measured by static tensiometry using the Du Nouy ring.
The principle of the measurement are discussed in WO12110302, which is incorporated by references in its entirety.
