"Look for a moisturizer with moisture-binding humectants that are especially helpful to soften skin's texture and keep skin looking plump, firm and dewy," she says.
|
|
In e-cigarettes, humectants act as a base liquid for the other ingredients and is usually a blend of vegetable glycerin (VG) and propylene glycol (PG).

But if you're dealing with acne and dryness at the same time, ditch the emollients and occlusives and stick to humectants instead, to keep skin clear and hydrated.
|
|
Epara Moisturizing Face Cream (about $139) contains humectants and emollients that create long-lasting hydration and improve barrier function over time (which helps your skin hold in the hydration it has).
|
|
Granted, I didn't check that all the makeup I used was free from moisturizing agents (some foundations in particular have glycerin or other humectants), but I did well and truly quit the creams.

Ells doesn't want anything on Chipotle's menu that customers can't immediately identify as something they could pick up themselves at the supermarket (Humectants are ingredients added to maintain foods' textures.) Panera Bread told Business Insider that it was working to use more "whole" ingredients instead of natural flavors.

To achieve 0.6-0.84 water activity in food products, partial drying is employed for raw food that naturally have a high amount of humectants such as raisins, apricots, prunes and sultanas. Humectants are solutes (such as sugar or salt) that immobilize water in food. The drying process removes free water, and the humectants in the product bind the rest of the water, not allowing it to be utilized for chemical reactions or for microbial use.

Archives of Toxicology, 86, 1309–1316 The main health concern regarding e-cigarettes is that their production is not regulated, and there is immense uncertainty of quality control during manufacturing. Self-rolled tobacco contains more humectants, which are added to tobacco to make it taste better and keep from drying out. As the humectants burn, they unleash chemicals such as acrolein. Humectants are found in most cigarettes and are considered one of the most dangerous chemicals found in tobacco.Roll-ups.

A number of food items always need to be moist. The use of humectants reduces the available water, thus reducing bacterial activity. They are used for safety issues, for quality, and to have a longer shelf-life in food products. An example of where humectants are used to keep food moist is in products like toothpaste as well as certain kinds of cookies.

Glycerol or glycerin humectants undergo a pretreatment process using saponification, bleaching, ion exchange exclusion, both cationic and ionic ion exchanges, vacuum flash evaporation, thin film distillation, and heating to produce a 100% pure glycerol.Msagati, Titus A. M. The Chemistry of Food Additives and Preservatives. Oxford: Wiley-Blackwell, 2013. PDF. Humectants are used in stabilization of food products and lengthening shelf life through food and moisture control.

This data demonstrated that increasing amounts of humectants in the unburned tobacco lowered the temperature in the waterpipe head during smoking, so that considerable amounts of toxic substances were present. Further, e-cigarettes produce aerosol by heating a humectant containing nicotine without burning tobacco. Those "vaping" then inhale the aerosol and receive nicotine.Schubert, J. Waterpipe smoking: the role of humectants in the release of toxic carbonyls.

Some common humectants used in food are honey and glucose syrup both for their water absorption and sweet flavor. Glucose syrup also helps to retain the shape of the product better than other alternatives, for a longer period of time. In addition, some humectants are recognized in different countries as good food additives because of the increase in nutritional value that they provide, such as sodium hexametaphosphate.Broad Chemicals as Food Additives. (2010).

Some of these humectants are seen in non-ionic polyols like sucrose, glycerin or glycerol and its triester (triacetin). These humectant food additives are used for the purpose of controlling viscosity and texture. Humectants also add bulk, retain moisture, reduce water activity, and improve softness. A main advantage of humectant food additives is that, since they are non-ionic, they are not expected to influence any variation of the pH aqueous systems.

The available moisture determines microbial activity, physical properties, sensory properties and the rate of chemical changes, that if not controlled, are the cause of reduced shelf life. Examples are dry cereal with semi-moist raisins, ice cream in a cone, chocolate, hard candy with liquid centers and cheese. Humectants are used to stabilize the moisture content of foodstuffs and are incorporated as food additives. Humectants are also used in military technology for the use of MREs and other military rations.

Humectants are used in the manufacturing of some tobacco products, such as cigarettes, e-cigarettes, and self-rolled tobacco. They are used to control and maintain the moisture content of the cut tobacco filler and add flavor. Humectants are vital to the creation of cigarettes. In an examination of waterpipe smoking, researchers worked to identify substances such as formaldehyde, acetaldehyde, and acrolein in the smoke of a waterpipe, discovering that the value of formaldehyde detected in one smoking session was five times higher than that of a regular cigarette.

Hair volumizers contain humectants, which work by attracting moisture from the surrounding areas to the hair strand, thereby swelling the hair and making it look thicker. Various polymers present in the volumizer coat the hair strand, making it look thicker and shiny.Evelyn R. Scott Hair Care Like A Pro 2015 When shopping for a volumizer, look for ingredients like starch, which soaks up extra oil, protein that helps your hair's texture, humectants for dry hair and polymers, which help to thicken each strand of hair. Shampoo and conditioner forms of the volumizers are used just like ordinary shampoo or conditioners.

A humectant is a hygroscopic substance used to keep things moist. They are used in many products, including food, cosmetics, medicines and pesticides. When used as a food additive, a humectant has the effect of keeping moisture in the food. Humectants are sometimes used as a component of antistatic coatings for plastics.

Osmotic dehydration is the process of soaking food in highly concentrated solutions of humectant. Salt and sugar are commonly used humectants for this process. Water diffusion from the food to the humectant solution is caused by osmotic pressure. The water is replaced by the humectant, which results in a lowered water activity for the food product.

Traditionally, techniques such as drying, salting and smoking have been used, and have been used for thousands of years. These techniques can be very simple, for example, by using solar drying. In more recent times, freeze-drying, water binding humectants, and fully automated equipment with temperature and humidity control have been added. Often a combination of these techniques is used.

Lauryl methyl gluceth-10 hydroxypropyl dimonium chloride is an ingredient in some types of soaps and personal care products. It is used as a substantive conditioning humectant. This chemical is a type of methyl glucoside derivative, which has been modified by ethoxylation and quaternization. A synthetic pathway for lauryl methyl gluceth-10 hydroxypropyldimonium chloride and other methyl glucoside humectants has been outlined in trade literature.

China Chemical Reporter, 21(4), 12. In order to gauge a compound's humectancy, scientists will put it through a series of tests, often involving water absorption. In tests involving toothpaste, the process is also coupled with a sweetness test and a crystallization test. When humectancy is being assessed in different products, testers will compare the results to other humectants that are already used in those products, in order to evaluate efficiency.

In addition to soap, lather shaving creams include a humectant for softer consistency and keeping the lather moisturised. Brushless shaving creams, on the other hand, don't contain soap and so don't produce lather. They are an oil-in-water mixture to which humectants, wetting agents, and other ingredients are added. Aerosol shaving creams are basically lather shaving cream in liquid form with propellants, vegetable waxes, and various oils added.

These are the mildest form of toners; they contain water and a humectant such as glycerine, and little if any alcohol (0–10%). Humectants help to keep the moisture in the upper layers of the epidermis by preventing it from evaporating. A popular example of this is rosewater. These toners are the gentlest to the skin, and are most suitable for use on dry, dehydrated, sensitive and normal skins.

In addition to medication, treatment for mental illness might include baths, music, and occupational therapy reflecting the great emphasis placed on the relationship between illness of the mind and problems in the body. Medicine would be prescribed in order to re-balance the four humors of the body, an imbalance of which might result in psychosis. Insomnia, for example, was thought to result from excessive amounts of the dry humors which could be remedied by the use of humectants.

Skin ageing is associated with increased vulnerability. Skin problems including pruritus are common in the elderly but are often inadequately addressed. A literature review of studies that assessed maintenance of skin integrity in the elderly found most to be low levels of evidence but the review concluded that skin- cleansing with synthetic detergents or amphoteric surfactants induced less skin dryness than using soap and water. Moisturizers with humectants helped with skin dryness, and skin barrier occlusives reduced skin injuries.

Natural skin care uses topical creams and lotions made of ingredients available in nature. Much of the recent literature reviews plant-derived ingredients, which may include herbs, roots, flowers and essential oils, but natural substances in skin care products include animal-derived products such as beeswax, and minerals. These substances may be combined with various carrier agents, preservatives, surfactants, humectants and emulsifiers. There are no legal definitions in the U.S. for advertising terms "natural" or "organic" when applied to personal care products.

Sugiyo Crab stick "Kaori-bako" Lean meat from fish or land animals is first separated or minced. The meat then is rinsed numerous times to eliminate undesirable odors. The result is beaten and pulverized to form a gelatinous paste. Depending on the desired texture and flavor of the surimi product, the gelatinous paste is mixed with differing proportions of additives such as starch, egg white, salt, vegetable oil, humectants, sorbitol, sugar, soy protein, seasonings, and enhancers such as transglutaminases and monosodium glutamate (MSG).

These barrier creams can be classed as occlusives (which prevent loss through a hydrophobic effect), humectants (which absorb water from the dermis and environment due to hygroscopy), or hydrating agents (which both moisturize the skin and maintain its water content). Barrier creams may contain substances such as zinc oxide, talc or kaolin to layer over the skin. Other barrier creams are intended to protect the skin from some external agents, though they are not sufficient to provide a complete barrier.

Osmotic dehydration process results in two way mass transfer in regards to the moisture lost and the solids gained, with moisture loss being much greater than the addition of solids. Advantages of osmotic dehydration include low processing temperatures, short drying times, and 20-30% lower energy consumption than typical dehydration processes. Sugar is used as the humectant for candied intermediate moisture fruits, and salt is used for intermediate moisture vegetables and fish. Additionally, a mixture of humectants can be formulated to manipulate the sensory properties of the food product.

Embalming chemicals are a variety of preservatives, sanitizers, disinfectant agents, and additives used in modern embalming to temporarily delay decomposition and restore a natural appearance for viewing a body after death. A mixture of these chemicals is known as embalming fluid, and is used to preserve deceased individuals, sometimes only until the funeral, other times indefinitely. Typical embalming fluid contains a mixture of formaldehyde, glutaraldehyde, methanol, humectants and wetting agents, and other solvents that can be used. The formaldehyde content generally ranges from 5-35%, and the methanol content may range from 9-56%.

Heated tobacco products aim for a niche between combustible tobacco smoking and electronic cigarettes that aerosolize nicotine suspended in humectants. Since the 1960s heated tobacco products were in development by tobacco companies. Safer heated tobacco products that deliver nicotine but limit emissions of tar or carbon monoxide (CO) is a half- century old idea, which had been unsuccessfully market-tested since 1988, first as Premier by the RJ Reynolds Tobacco Company (RJR) and later as Eclipse (RJR) and Accord (PMI). As of 2018, various heated tobacco products were reintroduced to the market.

Cats are at particular risk due to their instinctive method of grooming their fur with their tongues. Shampoos that are especially designed to be used on pets, commonly dogs and cats, are normally intended to do more than just clean the pet's coat or skin. Most of these shampoos contain ingredients which act differently and are meant to treat a skin condition or an allergy or to fight against fleas. The main ingredients contained by pet shampoos can be grouped in insecticidals, antiseborrheic, antibacterials, antifungals, emollients, emulsifiers and humectants.

An antistatic agent is a compound used for treatment of materials or their surfaces in order to reduce or eliminate buildup of static electricity. Static charge may be generated by the triboelectric effect or by a non-contact process using a high voltage power source. Static charge may be introduced on a surface as part of an in-mold label printing process. The role of an antistatic agent is to make the surface or the material itself slightly conductive, either by being conductive itself, or by absorbing moisture from the air; therefore, some humectants can be used.

The copoly-(succinimide-aspartic acid) formed by partial hydrolysis and especially polyaspartic acid (trade name Baypure® DS 100) produced by partial hydrolysis is suitable as a long-lasting inhibitor against limescale deposition in water treatment and applications in the oil and mining industries, and as a setting retarder for cement in the construction industry. Patent literature mentions polysuccinimide applications as chelating agents, inhibitors against scale formation, dispersant, humectants, and fertilizer additives. The opening of the pyrrolidinedione ring structures in polysuccinimide via aminolysis with ammonia water (containgin NH4OH) produces poly-(α, β)-DL-asparagine, with hydrazine poly-(α, β)-DL-aspartylhydrazide (PAHy) and with functional amines, e.g. ethanolamine poly-(α), β)-DL-2-hydroxyethylaspartate (PHEA).

In addition to water, the non-dye components (collectively referred to as the vehicle) might include polymeric resins, humectants to retard premature drying, pH modifiers, anti-foaming agents, biocides to prevent fungal and bacterial growth, and wetting agents (surfactants). Surfactants reduce the surface tension of the ink; distilled water has a surface tension of 72 dyn/cm (72 × 10−3 N/m), but the desirable value for ink is between 38 and 45 dyn/cm (38 to 45 × 10−3 N/m). If the ink's surface tension were too high, then it would not flow through the pen; if it were too low, then the ink would run out of the pen with less control. Some users mix inks to create their own colours.

The most consumed cigarette brand in Pakistan is Gold Leaf Various additives are combined into the shredded tobacco product mixtures, with humectants such as propylene glycol or glycerol, as well as flavoring products and enhancers such as cocoa solids, licorice, tobacco extracts, and various sugars, which are known collectively as "casings". The leaf tobacco is then shredded, along with a specified amount of small laminate, expanded tobacco, BL, RL, ES, and IS. A perfume-like flavor/fragrance, called the "topping" or "toppings", which is most often formulated by flavor companies, is then blended into the tobacco mixture to improve the consistency in flavor and taste of the cigarettes associated with a certain brand name. Additionally, they replace lost flavors due to the repeated wetting and drying used in processing the tobacco. Finally, the tobacco mixture is filled into cigarette tubes and packaged.
