Solid Perfume: Solid Fragrance | Glossier You

Glossier is a beauty brand founded by Emily Weiss in 2014. It started as an online-only company, building on the popularity of the beauty blog "Into the Gloss". Glossier was one of the first direct-to-consumer beauty companies when it launched in 2014, and has grown to over 10 retail locations in addition to global distribution in Sephora, SpaceNK, and Mecca. The brand's products span skincare, makeup, bodycare, fragrance, and merch.

Perfume (UK: , US: ) is a mixture of fragrant essential oils or aroma compounds (fragrances), fixatives and solvents, usually in liquid form, used to give the human body, animals, food, objects, and living-spaces an agreeable scent. Perfumes can be defined as substances that emit and diffuse a pleasant and fragrant odor. They consist of artificial mixtures of aromatic chemicals and essential oils. The 1939 Nobel Laureate for Chemistry, Leopold Ružička stated in 1945 that "right from the earliest days of scientific chemistry up to the present time, perfumes have substantially contributed to the development of organic chemistry as regards methods, systematic classification, and theory."

Ancient texts and archaeological excavations show the use of perfumes in some of the earliest human civilizations. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds such as vanillin or coumarin, which allowed for the composition of perfumes with smells previously unattainable solely from natural aromatics.

Solid is one of the four fundamental states of matter (along with liquid, gas, and plasma), and is a way in which all matter can be arranged on a microscopic scale under certain conditions. Molecules in a solid are closely packed and do not slide past each other as is the case for fluids. Solids resist compression, expansion, or external forces that would alter its shape, with the degree to which they are resisted dependent upon the specific material under consideration. Solids also always possess the least amount of kinetic energy per atom/molecule relative to other phases or, equivalently stated, solids are formed when matter in the liquid / gas phase is cooled below a certain temperature. This temperature is called the melting point of that substance and is an intrinsic property, i.e. independent of how much of the matter there is.

Solids are characterized by structural rigidity and resistance to applied external forces and pressure. Unlike liquids, solids do not flow to take on the shape of its container, nor does it expand to fill the entire available volume like a gas. Much like the other three fundamental phases, solids also expand when heated, the thermal energy put into increasing the distance and reducing the potential energy between atoms. However, solids do this to a much lesser extent. When heated to its melting point or sublimation point, solids melt into a liquid or sublimate directly into a gas, respectively. For solids that directly sublimate into a gas, the melting point is replaced by the sublimation point. As a rule of thumb, melting will occur if the subjected pressure is higher than the substance's triple point's pressure, and sublimation will occur otherwise. Melting and melting points refer exclusively to transitions between solids and liquids. Melting occurs across a great extent of temperatures, ranging from 0.10 K for helium-3 under 30 bars (3 MPa) of pressure, to around 4,200 K at 1 atm for the composite refractory material hafnium carbonitride.

The atoms in a solid are tightly bound to each other in one of two ways: regular geometric lattices called crystalline solids (e.g. metals, water ice), or irregular arrangements called amorphous solids (e.g. glass, plastic). Molecules and atoms forming crystalline lattices usually organize themselves in a few well-characterized packing structures, such as body-centered cubic. The adopted structure can and will vary between various pressures and temperatures, as can be seen in phase diagrams of the material (e.g. that of water, see left and upper). When the material is composed of a single species of atom/molecule, the phases are designated as allotropes for atoms (e.g. diamond / graphite for carbon), and as polymorphs (e.g. calcite / aragonite for calcium carbonate) for molecules.

Non-porous solids invariably strongly resist any amount of compression that would otherwise result in a decrease of total volume regardless of temperature, owing to the mutual-repulsion of neighboring electron clouds among its constituent atoms. In contrast to solids, gases are very easily compressed as the molecules in a gas are far apart with few intermolecular interactions. Some solids, especially metallic alloys, can be deformed or pulled apart with enough force. The degree to which this solid resists deformation in differing directions and axes are quantified by the elastic modulus, tensile strength, specific strength, as well as other measurable quantities.

For the vast majority of substances, the solid phases have the highest density, moderately higher than that of the liquid phase (if there exists one), and solid blocks of these materials will sink below their liquids. Exceptions include water (icebergs), gallium, and plutonium. All naturally occurring elements on the periodic table has a melting point at standard atmospheric pressure, with three exceptions: the noble gas helium, which remains a liquid even at absolute zero owing to zero-point energy; the metalloid arsenic, sublimating around 900 K; and the life-forming element carbon, which sublimates around 3,950 K.

When applied pressure is released, solids will (very) rapidly re-expand and release the stored energy in the process in a manner somewhat similar to those of gases. An example of this is the (oft-attempted) confinement of freezing water in an inflexible container (of steel, for example). The gradual freezing results in an increase in volume, as ice is less dense than water. With no additional volume to expand into, water ice subjects the interior to intense pressures, causing the container to explode with great force.

Solids' properties on a macroscopic scale can also depend on whether it is contiguous or not. Contiguous (non-aggregate) solids are characterized by structural rigidity (as in rigid bodies) and strong resistance to applied forces. For solids aggregates (e.g. gravel, sand, dust on lunar surface), solid particles can easily slip past one another, though changes of individual particles (quartz particles for sand) will still be greatly hindered. This leads to a perceived softness and ease of compression by operators. An illustrating example is the non-firmness of coastal sandand of the lunar regolith.

The branch of physics that deals with solids is called solid-state physics, and is a major branch of condensed matter physics (which includes liquids). Materials science, also one of its numerous branches, is primarily concerned with the way in which a solid's composition and its properties are intertwined.

In Modern English, the word "you" is the second-person pronoun. It is grammatically plural, and was historically used only for the dative case, but in most modern dialects is used for all cases and numbers.
