Frequently asked questions

Welcome to the ChemSec Marketplace, our B2B platform for safer alternatives to hazardous chemicals. You can read more about the project here.


Q: What is regarded as an alternative?

A: All solutions to hazardous chemicals are welcome: chemical substitutes as well as new technical solutions that negate the use of a hazardous substances altogether. The terms and conditions can be found here.


Q: Who can advertise on the Marketplace?

A: All companies that offer solutions that can be used to replace hazardous chemicals. As a downstream user, or buyer of alternatives you can also post “requests”.


Q: What should I do if I find an interesting alternative?

A: For each ad you can find contact details for the advertising company. You will need to make contact with the company yourself to continue the discussion. The Marketplace only provides a platform for contact and for displaying the products available on the market. No transactions will take place on the Marketplace.


Q: What should I do if I do not find an interesting alternative?

A: You can formulate a request on Marketplace, so that companies offering solutions can contact you directly. You can also choose to be anonymous and if so ChemSec will forward any responses to your request to you.


Q: How does ChemSec make sure that advertised chemicals are not in fact hazardous?

A: Those companies that advertise on the Marketplace are individually responsible for providing correct information. ChemSec will moderate the site and remove ads that obviously do not fulfil the criteria, but it is beyond the scope of Marketplace to carefully investigate all alternatives. Prospective buyers are recommended to request documentation to back any claims made on the Marketplace. ChemSec also intends to introduce a reporting system in the future that will allow users to alert the moderators about any non-compliant ads.


Q: What does it cost to advertise?

A: At this stage: nothing. This might change in the future. However, we will not charge for ads retroactively. This means that ads that are created now will always be free.


Q: How many ads can I post?

A: As many as you wish – one for each alternative product. There will be obvious exceptions. Let’s say you produce a textile dye that comes in a hundred different colours, but the content is essentially the same. This should only be advertised in one ad, to avoid “spamming” of the website. If you mention all possible colour variations in the ad it will still be searchable by the users.


Q: How are the Marketplace and ChemSec financed?

A: ChemSec is a non-profit NGO. About half of its funds come from the Swedish government, the other half from various grant-making foundations. The Marketplace project is funded by the John Merck Fund.


Q: Does the Marketplace consider other environmental issues besides hazardous chemicals?

A: The focus and the starting point of the Marketplace are solutions to replace hazardous chemicals. However, any additional information provided in the ads about other types of environmental benefits of the specific product may be of interest to a potential buyer and is encouraged.


Q: How do I advertise at the Marketplace?

A: First you create a login, using the large green button in the top right corner. Once you have an account you can start to submit ads or requests.


Q: What information is required in an ad for alternatives:

A: First you need to tick a box that your alternative complies with the terms and conditions. Then you can add further information including a heading, summary, description, and which substance the alternative can replace. To make it easier for users to search for ads you are also recommended to fill in information on the Material Article Category, Sector of Use, Technical Function, legal requirements and third-party labels. The first three categories use similar descriptors as OECD and ECHA:

Description of the Technical Functions:

Name Explanation
Adhesion promotor Any substance, inorganic or organic, natural or synthetic, used to join opposite surfaces to each other, promote bonding between other substances, promote adhesion of surfaces, or fasten other materials together. They are generally applied from a solvent solution and allowed to dry on the two facing surfaces.
Antioxidant Substance that retards oxidation, rancidity, deterioration, and gum formation; used to maintain the quality, integrity, and safety of finished products by inhibiting the oxidative degradation of the ingredients in the formulation. Saturated polymers have greater oxidative stability and require relatively low concentrations of stabilizers.
Antistain agent Antistain agent is a substance that provides stain blocking and soil resistance to soft surface cleaners and protectors.
Binder Any cementitious material that is used to hold dry powders or aggregate together; added to compounded dry powder mixtures of solids to provide adhesive qualities during and after compression to make tablets or cakes; is soft at high temperatures and hard at room temperature.
Biocide Substance intended for preventing, neutralizing, destroying, repelling, or mitigating the effects of any pest or microorganism; that inhibits the growth, reproduction, and activity of organisms, including fungal cells; decreases the number of fungi or pests present; deters microbial growth and degradation of other ingredients in the formulation.
Bleaching agent A bleaching agent is a material that lightens or whitens a substrate through chemical reaction. The bleaching reactions usually involve oxidative or reductive processes that degrade colour systems.Bleaching and decolourization can occur by destroying one or more of the double bonds in the conjugated chain, by cleaving the conjugated chain, or by oxidation of one of the other moieties in the conjugated chain.
Brightener Substance that is used to brighten, whiten, or enhance the appearance of colour of fabric and paper, usually by absorbing light in the ultraviolet and violet region (340-370 nm) of the electromagnetic spectrum, and re-emitting light in the blue region (420-470 nm). This causes a "whitening" effect by increasing the overall amount of blue light reflected. Optically colourless on the substrate and do not absorb in the visible part of the spectrum.
Catalyst Substances that increase the efficiency of a chemical reaction e.g. reaction needs less energy. Catalysts take part in the reaction but are not consumed during the process.
Cleaning agent Substance or material used to remove dirt or impurities from surfaces; acts to loosen and remove dirt and grease from surfaces.
Corrosion inhibitor Chemical substance used to prevent or retard corrosion metallic materials. They are needed in many products packaged in metal containers (such as aerosol products) and also used in such products as lubricants and other metal treatment products to provide protection to the substrates or surfaces on which the lubricants are used.
Dispersing agent Substance added to a suspending medium or suspension to improve the separation of particles; to ensure proper dispersion; to prevent settling or clumping; to encourage uniform and maximum separation of individual, extremely fine solid particles or liquid droplets, often of colloidal size. A typical use is dispersal of dyes to ensure uniform coloration.
Dye Substance used to impart colour to other materials or mixtures; added to a material to add colour; soluble. Molecularly dispersed within a liquid, transferred to a material, and bound to that material through intermolecular forces. Typically an organic substance, although exceptions do exist. A dye requires some degree of solubility that allows it diffuse into the polymeric matrix of a textile fibre.
Finishing agents Chemical substances used to impart such functions as softening, staticproofing, wrinkle resistance, and water repellence. Substances may be applied to textiles, paper, and leather.
Fixing agent (mordant) Substance used to interact with a dye on fibres to improve fastness.

Pigment Any substance, usually in the form of a dry powder, that imparts colour to another substance or mixture by attaching themselves to the surface of the substrate through binding or adhesion; may contribute towards opacity, durability, and corrosion resistance. Must have positive colorant value; larger than molecular particle size and held in place by corresponding low mobility; scatter and absorb light.Pigments differ from dyes in that they are insoluble in the vehicle and exist as dispersed compounds in paint rather than as a solute.
Plasticizer An organic compound that softens synthetic polymers; added to a high polymer to facilitate processing and to increase flexibility, plasticity, fluidity and toughness of the final product by internal modification (solution) of the polymer molecule. Plasticizers may be added internally or externally. A rigid polymer can also be externally plasticized by addition of a plasticizer, which imparts the desired flexibility but is not chemically changed by reaction with the polymer.
Plating agent Substances/materials used as a source for a layer of metal deposited on another surface, or that aid in such a deposition. These are used in processes such as electroplating, galvanization or coating.
Reactive cleaning/removal agent Substance that reacts with and removes surface contaminants and is generally consumed, e.g., oxides, sulfides.

Antiscaling agent Substances added to products to prevent the build-up of inorganic oxide deposits. The formation of scale can be caused by the deposition of salts or minerals and may not necessarily lead to surface corrosion, therefore these chemicals are not corrosion inhibitors. Substances prevent the build-up or removes limescale and fouling. These substances are also called ‘Descalers’.
Antistatic agent Any substance that prevents or reduces the tendency of a material to accumulate a static charge or alters the electrical properties of materials by reducing their tendency to acquire an electrical charge.
