Zest-it® is made here in the UK, it is a natural solvent made from
'pure food grade' ingredients - the zest from the peel of oranges, which is why it smells of oranges i.e. citrus smell. It does not mix with water. Zest-it is
not what is commonly referred to as 'citrus thinner'.
This citrus oil would, for many people, be too strong to use on it's own. So it is diluted with a non-ozone depleting hydrocarbon type solvent, that is non-toxic, non-flammable and with a low vapour pressure. The
'low vapour pressure' means there is very little emission of any part of Zest-it to the atmosphere.
The product has undergone much testing, both here in the UK and in the USA. The Environmental Health and Safety test products for personal exposure, with regards to irritation of the skin and eyes;
ingestion and inhalation - of the original undiluted product. If you wonder why it has a 'harmful' notice on the label, click here
Zest-it it not classified as a Dangerous substance, therefore the supply of MSDS is not mandatory according to Directives 91/155/CEE and 93/112/CEE. 
(This is a legal document changing altering or misrepresenting the information is illegal and dangerous)
To help members of the general public who use our products, the following information for Zest-it® is taken from the MSDS. It is explained in 'easy to understand' terms with the First Aid measures.
Skin irritation has four categories -
1 for non-irritating - must rate between 0.00 and 1.90;
2 for moderately irritating - must rate between 2.00 and 4.90;
3 for Primary skin irritant - rated 5.00 and over;
4 for corrosive.
Zest-it comes into category 1 with a score of 0.02.
If your skin already shows any form of sensitivity in the way of dermatitis or a know skin allergy, then Nitrile gloves are recommended. Zest-it removes oil paint from brushes, and because it removes oils, it can also remove your skins natural oils, so prolonged contact may cause skin dryness and cracking.
As always when you are painting, 'common sense' needs to prevail, if you know you always have 'wet' hands from using solvents, then frequent washing with a good quality soap, that puts the oils back into your skin, is an excellent painting practice.
(First Aid measures - Wash with soap and water, remove any contaminated clothing and shoes).
Eye irritation has four categories also -
1 for non-irritating - must rate between 0.00 and 15.00
2 for slightly irritating - must rate between 15.10 and 25.00 (the effects
clear within 7 days)
3 for moderately irritating - must rate between 25.10 and 50.00 (the effects clear within 21 days)
4 for severely irritating (or corrosive) (the effects persist for 21 days or more)
Zest-it comes into category 1 with a score of 0.00.
Again 'common sense' is needed, if you know you splash the solvent around then wear protective goggles.
(First Aid measures - flush well with water) Ingestion (eating or drinking) of the original undiluted product has three categories -
3 for highly toxic - less than 50 milligrams per kilogram of body weight.
2 for toxic - between 50 and 5000 milligrams per kg of body weight.
1 for non-toxic - more than 5000 milligrams per kg of body weight.
Zest-it comes into category 1 and has a score of 17,750 milligrams per kg of body weight.
So if you weighed about 8 stone/51 kg you would need to ingest about 1 litre (just under 2 imperial pints) before it became lethal, but for a child weighing only 1 stone then the quantity would be 130 ml (just over ¼ of a imperial pint), hence 'keep out of reach of
children'.
(First Aid measures - Do not induce vomiting. May be harmful if
ingested into the lungs. Seek medical advice). See note below.
Inhalation (breathing) of the original product has three categories -
3 Highly toxic - less than 2 milligrams per litre by volume when inhaled continuously for an hour or less.
2 Toxic - more than 2 milligrams but less than 200 milligrams per litre by volume when inhaled continuously for an hour or less.
1 Non-Toxic - more than 200 milligrams per litre by volume when inhaled
continuously for an hour or more.
Zest-it is classed as Non-toxic being rated 800/1200 milligrams per litre by volume, therefore adequate natural ventilation will suffice in most instances.
(First Aid measures - Remove patient to fresh air, keep at rest and seek medical advice). Carcinogenicity listing - NPT - None; IARC - None; OSHA - None; ACGIH - None. Flammability - Don't forget, the higher the materials flash
point, the less flammable it is. -
A flash point of between 30 - 40 ºC is flammable.
Zest-it has a flash point of 67ºC and is therefore classed as Non-flammable,
but like most solvents it is best kept away from sources of ignition.
Fire fighting measures -
Water fog, CO², dry powder or foam. The use of water streams should be avoided as this will tend to spread the fire. Burning product will liberate CO² and possibly CO.
Avoid breathing smoke.
Accidental release measures -
Contain and absorb with dry sand or oil absorbent, dispose of as dry oil waste. Used or contaminated product should not be allowed to enter streams or sewers.
Handling and storage -
Do not handle or use near open flames or sources of ignition. Store in cool well ventilated place away from sources of ignition.
Stability and reactivity -
As with any organic material combustion will liberate carbon dioxide and/or carbon monoxide. Avoid contact with strong oxidising agents.
Disposal considerations -
This product is classified as inherently Biodegradable.
In its virgin state it may be disposed of as oil waste. Used or contaminated waste should be disposed of in accordance with the Contaminant.
This means if the product contains oil paint pigment/sludge it should not be thrown down the sink, put onto dry sand or soil before disposing. Transportation information -
This material is not regulated for transport by road, air or sea.
This means there are no restriction on transporting the product by road sea or air.
Zest-it has a Harmful notice on the label stating 'may cause lung damage if swallowed' this is because, if the product was swallowed and the person vomited, and the vomit entered the lungs, it could cause bronchopneumonia.
It also states 'may cause skin dryness and cracking' this is because prolonged contact - keeping the hands wet with Zest-it - will remove the natural oils from the skin, causing the skin to dry and
further prolonged contact can cause cracking. Hence the label states 'wash hands after use'.
As a Company we supply this information for ease of access to the product Safety Data Sheet information (commonly known as an MSDS) for any member of the public who uses our products. Zest-it is not classified as a Dangerous substance, therefore the supply of MSDS is not mandatory for more information on this point please see legal information regarding MSDS.
