DIN 53160 Saliva · two-part kit

DIN 53160:2023-07

The artificial saliva as a 2-part formula, calcium in one part, phosphate in the other. Neither part is supersaturated, so the shelf life is the kit's and not the fluid's.

  • 2 × 500 mL · makes 1 L

Main Function & Applications

What limits ready-to-use saliva is not microbiology but crystallography: calcium and hydrogen phosphate share the bottle and the medium is supersaturated in brushite. Split them and nothing nucleates.

User Sectors & Laboratories

Good to know

The 1 % hydrochloric acid that brings the mixture to pH 6.8 is not supplied with the kit. Pour part A into part B, never the other way round. Calcium arriving in a large volume of phosphate disperses; phosphate poured into calcium seeds crystals that never redissolve.

SECTION 3
Composition / information on ingredients
3.2 Mixtures
Aqueous mixture. Chemical characterisation: inorganic salts and organic metabolites in purified water. Composition as formulated, per litre of ready-to-use solution:
Part A, Water (CAS 7732-18-5) > 99 % with magnesium, calcium, sodium and potassium chlorides. Part B, water with dipotassium hydrogen phosphate trihydrate (CAS 16788-57-1) and potassium carbonate (CAS 584-08-7). Each salt below 0.2 % in the reconstituted fluid.
No constituent is present at or above its generic concentration limit, so the mixture stays unclassified. Water is stated for completeness. No component is an SVHC of the candidate list at or above 0.1 % w/w.
SECTION 4
First aid measures
4.1 Description of first aid measures
General: remove soiled clothing. Show this safety data sheet to the doctor.
After inhalation: not an anticipated route of exposure, the product is a non-volatile aqueous solution. Move to fresh air if an aerosol has been generated.
After skin contact: wash with water and soap. If irritation persists, seek medical advice.
After eye contact: rinse with running water for at least 15 minutes, holding the eyelids apart. Remove contact lenses if present and easy to do. If irritation persists, seek medical advice.
After swallowing: rinse the mouth and drink water. Do not induce vomiting. Seek medical advice if symptoms occur.
4.2 Most important symptoms and effects, both acute and delayed
None expected under the conditions of use. A prolonged skin contact with an acidic formulation may cause transient reddening. No delayed effect is known.
4.3 Indication of any immediate medical attention and special treatment needed
Symptomatic treatment. No specific antidote is known or required.
SECTION 5
Firefighting measures
5.1 Extinguishing media
Suitable: water spray, carbon dioxide, dry powder, alcohol resistant foam. The product itself is not combustible and does not sustain a fire.
Unsuitable: none. Choose the media appropriate to the surrounding fire.
5.2 Special hazards arising from the substance or mixture
None specific. In a fire, evaporation of the water fraction may concentrate the dissolved salts and organic constituents in the residue. Thermal decomposition of the organic fraction can release carbon oxides and, where nitrogen bearing constituents are present, nitrogen oxides and ammonia.
5.3 Advice for firefighters
As in any fire, wear self-contained breathing apparatus and full protective clothing. Do not allow firefighting water to enter drains or watercourses.
SECTION 6
Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Wear the protective equipment of section 8. Beware of a slippery floor. No evacuation or special respiratory protection is required for a laboratory scale spill.

Revision
Revision 3.0 of 2026-09-06. This revision rewrites the sheet per product: sections 1, 2, 3, 7, 9, 11 and 16 now carry values specific to this reference rather than to the range. Section 9 is completed to the list of Annex II as amended by Regulation (EU) 2020/878, and section 11 states derived classification rather than an untested conclusion. Supersedes all earlier editions.
