A chemical additive that prevents spoilage by killing or inactivating microorganisms; an additive that prevents microbial contamination, usually employed in multi-dose containers.
Natural or synthetic substances added in small proportions to prevent any contamination of cosmetics by germs. A chemical sometimes added to a composition with the purpose of delaying effects of oxidation.
A substance that, when properly applied to wood, makes it resistant to attack by fungi, insects, or marineborers.
Any substance that, for a reasonable length of time, will prevent the development and action of wood-destroying fungi, borers of various kinds and other harmful insects that deteriorate wood after the wood has been properly treated with it; also wood preservative.
Any substance that is effective in preventing , for a reasonable period of time, the development and action of fungi, borer and insect attack in wood.
Either a chemical or reagent added to a sample to prevent or slow decomposition or degradation of a target analyte or a physical process (such as cooling) used for the same purpose. Both physical and chemical preservation may be used in tandem to prevent sample deterioration.
having the ability to protect something from decay or spoilage.
Substance added to a product to prevent it from spoiling. Preservatives act by slowing down or stopping certain chemical reactions or stop the growth of moulds, fungi or bacteria. To have a realistic shelf life, commercially manufactured products which contain water must contain preservatives; otherwise products must be kept in the refrigerator and replaced every few days. Preservatives also prevent skin infections from harmful bacteria that may otherwise be present. Everyday preservatives include sugar, salt, vinegar, Potassium Sorbate and Benzoic Acid.
a chemical compound that is added to protect against decay or decomposition
a material that protects the product from the effects of microbiological contamination and deterioration
an additive for foods, pharmaceuticals, personal care products, cosmetics and other industrial products to reduce spoilage that air, fungi, bacteria, or yeast can cause
a natural or synthetic chemical A chemical compound is a chemical substance formed from two or more elements, with a fixed ratio determining the composition
a substance, such as sodium benzoate or potassium sorbate, that enables soft drink products to have a longer shelf life by inhibiting or arresting the growth of micro-organisms such as yeasts, moulds and bacteria
A chemical compound applied as a liquid, which is used to help prevent rot and/or insect damage to wood. Sometimes, but not necessarily a stain.
A chemical added to a water sample to keep it stable and prevent compounds in it from changing to other forms or microorganism densities from changing prior to analysis. Protons - Positively charged particles found in the nucleus of an atom.
Any substance applied to wood that helps it resist decay, rotting, or harmful insects.
A substance that protects against the natural effects of aging, such as decay, discoloration, oxidation, and spoilage. In soap products, preservatives are used to prevent or slow down the natural tendency to develop rancidity upon aging. Preservatives also protect colors and fragrances. Butylated hydroxytoluene, stannic chloride, or EDTA are the most commonly used preservatives in the cleaning chemical industry.
An ingredient that protects against the natural effects of product aging (for example, decay, discolouration, oxidation and bacterial attack).
Chemical added to food to prevent spoilage
A substance used to prevent the growth of microorganisms in or on an organic base. An example is an ingredient in water-based paint used to prevent spoilage.
A substance added to a product to destroy or prevent the growth of microorganisms.
A natural ingredient that is added to a formulation to slow or prevent spoilage. Many also function as antioxidants (e.g., tocopherols, vitamin C). Most often utilized in supplements containing unstable liquids.
Chemical sprayed or painted onto wood to prevent rotting and decay.
usually paraformaldehyde. Any material used to prevent starch or any other substance from fermenting through bacterial action.
Substance that slows down deterioration of organic materials and prevents bacterial growth.
Also called antimicrobial. Keep dangerous organisms such as bacteria, fungi, yeasts and molds from growing in a product. Some preservatives are known to be sensitizers.
An additive that protects vaccine against contamination or spoilage.
A natural or synthetic chemical added to a product to prevent spoilage or undesirable change.
Any substance that, for a reasonable length of time, will prevent the action of wood-destroying fungi, borers of various kinds, and similar destructive agents when the wood has been properly coated or impregnated with it.
An agent that prevents the deterioration of materials; usually associated with the prevention of biological deterioration.
An additive used to protect against decay, discoloration, or spoilage.
a substance added to food products or to organic solutions to prevent decomposition due to chemical change or bacterial action
A material that prevents or inhibits the growth of microorganisms in organic mixtures.
chemical, commonly sodium sulfite, used in developing solutions to prevent rapid oxidation of the reducing agents in use.
Substance added to protect, prevent, or retard decay, discoloration, or spoilage under conditions of use or storage. See Biocide, Fungicide
Chemical that protects from deterioration, rot or infestation of materials, such as wood. Copper napthenate and pentachlorophenol are commonly used as preservative for wood that is exposed to such conditions.
A preservative is a natural or synthetic chemical that is added to products such as foods, pharmaceuticals, paints, biological samples, etc. to retard spoilage, whether from microbial growth, or undesirable chemical changes.
