A-Z List of Beauty Ingredients
Decode beauty speak with our A-Z of beauty ingredients. A quick scan through our glossary should inform and illuminate. And if we can just add one thing: Please treat this as a generic guide; if you want more information please 'google it'.
Acetone A colourless, flammable solvent that is the active ingredient in nail polish remover. Also found in nail finishes and used as an astringent in skincare applications. May cause skin irritation, such as stinging, rashes and drying. Can cause lung irritation if inhaled.
> Acetyl Glyceryl Ricioleate A semi-synthetic compound derived from glycerin and castor oil fatty acids. Used as an emollient and thickening agent in cosmetics.
> Acetyl Hexapeptide-3 A synthetic peptide also known by its trademark name Argireline. It is manufactured by the Spanish company Lipotec, which claims it has effects similar to botox. Acetyl hexapeptide-3 purportedly inhibits the release of neurotransmitters, relaxing facial tension, leading to a reduction in fine lines and wrinkles. There are no clinical studies to substantiate these claims, and no research on its safety.
> Acetylated Lanolin An organic compound derived from lanolin (fat produced by the sebaceous glands of sheep and extracted from their wool). Acetylated lanolin has been reacted with acetic acid and is commonly used as an emollient due to its excellent moisturising properties (it closely resembles human sebum). However, it can aggravate acne.
> Alchemile An extract of lady's mantle (botanical name: alchemilla). Widely used in herbal medicine to control bleeding and alleviate menstrual cramps. In topical applications it is used for its anti-elastase and free radical scavenging activity. Elastase is responsible for breaking down collagen and elastin, therefore use of alchemile is said to improve skin elasticity and reduce wrinkles. Has an astringent effect on skin. Active compounds are tannins (which may irritate) and trace salicylic acid.
> Algae Marine algae are chlorophyll-containing organisms, ranging from simple single cell formations to more complex multi-cell forms, such as seaweed. Seaweed is a natural thickening agent commonly found in cosmetics. It is also used for its water binding and antioxidant attributes. Blue-green algae may cause skin irritation. See Carrageenan, Fucus Vesiculosis, Palmaria Palmata and, Seaweed Extract.
> Alkyloamides Synthetic fatty acids. Some common forms are DEA (diethanolamine), cocamide DEA, triethanolamine (TEA), and MEA (monoethanolamine). They are used variously in skincare and beauty products as foam boasters, emulsifiers, waxes, thickeners, gelling and conditioning agents. Primarily found in shampoos, soaps, bubble baths, hand and body cleansers.
> Allantoin Allantoin is a botanical extract of comfrey that has healing and anti-irritant properties. It is a mild astringent that softens and soothes skin while promoting healthy tissue. Found in a wide array of cosmetic and pharmaceutical products, particularly anti-acne, sun care and clarifying lotions. Often present in oral hygiene products, shampoos and lipsticks.
> Aloe Vera From the aloe vera plant, one of the oldest medicinal plants known. Commonly used in concentrated gel form. Renowned for its softening and soothing properties, it is particularly beneficial for sunburned skin. It is an excellent emollient that provides a refreshing, cooling sensation when applied to skin. Therapeutic benefits include healing and anti-irritant properties, but studies are inconclusive.
> Alpha Bisabolol A compound of the essential oil of chamomile that has anti-inflammatory, anti-spasmodic, anti-microbial and mild sedative effects. Studies have shown that it reduces fever and shortens the healing time of burns in animals.
> Alpha Hydroxy acids (AHAs) Alpha Hydroxy Acids are commonly known by their acronym AHA. AHAs are derived from plant sources and milk, the most effective being glycolic (sugar cane) and lactic acids (sour milk or molasses). Most topical applications are synthetically derived. Concentrations of 5% or more exfoliate the skin by breaking down the substance that holds cells together, sloughing away old dead skin while stimulating collagen production. Proven to be effective in treating sunspots, fine wrinkles, skin texture and acne, it is thought they work by irritating skin, which triggers a healing response. The higher the concentration the higher the irritation, with redness, stinging, peeling, blistering and sun sensitivity as known side effects. Doctors may administer acid peels in concentrations of up to 70%. There is concern that cells have a limited potential for renewal, and that over use of AHAs could be harmful. A UV sunscreen should be used in conjunction with AHA use.
> Alpha Lipoic Acid A powerful and versatile water and fat-soluble antioxidant that helps deactivate a wide range of cell-damaging free radicals. There are ongoing studies into its effectiveness in treating age-related disease in humans and animals, but they are still in the early stages. May be taken as a supplement or applied topically via cosmetic applications where it is professed to minimise lines and increase skin resilience and texture.
> Amino Acids Amino acids are the building blocks of protein, one of the biggest components of our bodies. Non-essential amino acids are synthesised by the body, while essential amino acids must be obtained from food sources. In cosmetics they are primarily used for their water binding and emollient properties.
> Anise Pimpinella anisum - a flowering plant also known as aniseed or anis. Has antioxidant and antibacterial properties and is used in many herbal remedies. Anise extracts can be found in oral hygiene products, perfumes and skincare formulations. It can be a potential skin irritant and may cause photosensitivity.
> Anthocyanocides A potent bioflavonoid derived from anthocyanins (Etymology (Greek) anthos:flower, kyáneos:purple). The pigments responsible for the red, blue or violet colours in flowers and fruits, eg blueberries. Anthocyanocides scavenge oxidants and free radicals as well as boosting intracellular vitamin C levels.
> Antiglyskin® An extract of sunflower that is rich in phenolic acids and glycopeptides. Prevents glyco-oxidation and is used as an active anti-ageing agent in skin care products.
> Antioxidant A chemical that reduces oxidation of cells. Antioxidants are produced by the body and obtained from dietary sources. Cells are oxidised when exposed to environmental (sunlight, pollution, smoking) free radicals (compounds that contain oxygen molecules). This oxidisation damages the cells' components and can even cause cellular death. All living organisms have complex antioxidant systems to guard against this damage. Examples of antioxidants are vitamins A, C and E, flavonoids and coenzyme Q10.

A group of enzymes known as oxidoreductases are said to have anti-oxidant properties. Enzymes are commonly identified through the 'ase' suffix, eg papaya: proteinase papain. See bromelain, papaya.
> Epaline® A derivative of corn oil extract that has been enriched with oxygen. It is used for its anti-inflammatory and soothing properties.
> Essential Fatty Acids (EFAs) Commonly known as omega 3 (alpha-linolenic acid) and omega 6 (linoleic acid). Essential to human health these polyunsaturated fats cannot be manufactured by the body and must be obtained through nutritional sources. EFAs play an important role in cell membrane structure: they are necessary for the proper functioning of body cells, and influence the shape and fluidity of membranes. They help preserve moisture and have anti-inflammatory properties. Supplemental use of omega 3s has shown to benefit skin disorders such as psoriasis and eczema. Topically, EFAs may be used in skin formulations as emollients. For further info visit: http://www.canolainfo.org/resources/litsearch.html
> Ester-C® The trademark name of a patented non-acidic form of vitamin C. The makers claim that ester-C® is absorbed faster and retained more readily than ordinary vitamin C due to the addition of vitamin C metabolites. It is used in cosmetic formulations where it purports to deliver the collagen and antioxidant benefits of vitamin C with far higher stability and penetrability. There is little independent data substantiating these claims and it is argued that the best form of vitamin C is that which is naturally synthesised by animals. See ascorbic acid.

Talc is also found in medicated and perfumed body powders. Talc may contain asbestos fibres, although cosmetic grade talc (asbestos free) is classified as 'generally recognised as safe'. There is still a risk of possible contamination with impurities as cosmetic grade talc is non-regulated. Studies support a link between the use of talcum powder in the genital area and ovarian cancer. Talc is toxic, and may cause respiratory illness or death if inhaled. The European Union has mandated that talcum powder is not to be used in products for children under the age of three. See Toxic Beauty.
> Tallow Rendered beef or mutton fat. Its derivatives (acids, amines, amide etc) have many functions including emulsifying, foam boasting, refatting, surfactant and emollient.

> Vegetal Squalane Squalane is a hydronated form of squalene. Squalene is found naturally in vegetable oil, shark oil and the human sebum, but is unsuitable for use in cosmetics as it is highly unstable. The stable version; vegetal squalane, is a light oil close in structure to human lipids that is easily absorbed by the skin and does not leave a greasy residue. Used for its ability to attract water, it hydrates and softens skin.
> Vitamin A Plays an important role in vision, bone growth, immune function and tissue and skin formation. There are two forms: provitamin A, a carotenoid found in fruits and vegetables, and preformed vitamin A that is absorbed in the form of retinol from animal sources such as beef, chicken liver, milk and eggs. Topically the skin rejuvenation effects of retinoid forms (retinoic acid, retinyl palmitate, isotretinoin, tretinoin [retin A] and retinol) are well documented. They work by increasing cell turnover and are used to treat photoaged skin, age spots, acne and psoriasis. Can cause skin irritation and flaking. Vitamin A oral supplementation and topical application should be avoided during pregnancy, as excess levels are known to cause birth defects. See Beta Carotene, Retinol.

Also used in skincare where it is said to aid tissue repair and inhibit inflammation.
> Vitamin B6 Pyridoxine - one of eight water soluble B vitamins known as B-complex vitamins. Like all B vitamins it is involved in energy production, converting carbohydrates into sugar, and plays an important role in maintaining healthy skin, hair and nails. An especially important B vitamin that is involved in many enzymatic processes as well as nerve function and cell formation. Deficiency can cause anaemia, and skin disorders such as dermatitis and eczema. Sources: spinach, brown rice, chicken, tuna, liver, banana.
> Vitamin C Ascorbic acid- an essential nutrient and potent anti-oxidant. An important antioxidant vitamin integral to the formation and maintenance of collagen, a protein used to make skin, scar tissue, tendons, ligaments, and blood vessels. It enhances iron absorption and protects cells against free radical damage. Most animals and plants synthesise their own vitamin C, however humans cannot make or store it, therefore it must be constantly replenished from nutritional sources. A highly unstable acid that is oxidised on contact with air and destroyed when exposed to heat and light. For this reason it is extremely difficult to stabilise in skincare formulations. Applied topically, it may irritate skin due to high acidity levels. Its role in the growth and repair of tissues, and antioxidant activity makes it is an intregral element in the maintenance of healthy skin and hair. Deficiencies can lead to dry, splitting hair, rough, scaly skin, easy bruising and slow wound healing.
> Vitamin D Fat soluble vitamin essential for the formation and maintenance of healthy bones. There is also research showing that it is involved in regulating cell growth and differentiation, and supports the immune system. Vitamin D can is found in food and is also synthesised in the skin when the body is exposed to sunlight. Sources: cod liver oil, salmon, sardines, mackerel, shrimp and, egg yolk.
> Vitamin E A group of eight fat soluble antioxidant vitamins: four tocotrienols and four tocopherols. A very important antioxidant, one of its main functions is to protect lipids from oxidative damage. Studies show that oral and topical application protects against UV radiation. It may also slow down cellular and tissue ageing, reduce scarring and promote wound healing. See Tocotrienols
> Vitamin F Essential fatty acids were initially designated as vitamin F, until it was realised that they should be classified as fats. These essential nutrients are important for maintaining healthy skin and hair. See Essential Fatty Acids.
> Vitamin H Biotin - one of eight water soluble B vitamins known as B-complex vitamins. Like all B vitamins it is involved in energy production, converting carbohydrates into sugar, and plays an important role in maintaining healthy skin, hair and nails. Biotin is required for the synthesis of fat, a critical cell component. Deficiency can cause skin related problems like cradle cap or seborrheic dermatitis, and may also cause hair loss.

Considered a safe, non toxic alternative to phosphates, synthetic zeolites are used in many industries, including cosmetics where they function as absorbent, bulking and anti-caking agents. Zeolites can help control the rheology and tactile qualities of facial make-up.
> Zinc Oxide Also known as zinc white and Chinese white. A white or yellowish powder that occurs in nature as the mineral zincite. Used in sunscreen as a physical blocker that absorbs UV rays, zinc oxide is noticeable by the white residue it leaves on skin. Nanotechnology is now being employed to reduce the particle size, resulting in a clear product. While traditional zinc oxide is considered safe and non-toxic, there is limited information of the safety profile of micronised zinc oxide. Also found in formulations to protect skin from dehydration, wind and diaper rash. See Oxide Pigments.
