L(+)-Dextrorotatory Lactic Acid 21% precise concentration • food-grade quality • acidity control • easy measuring • versatile use • safety cap • 100 ml
L(+)-dextrorotatory lactic acid 21% 100ml is a clear to slightly yellowish liquid of food-grade quality with a precisely defined 21% concentration. According to the manufacturer’s specification, the L(+)-form can serve as a raw material for pH adjustment, food formulations, food supplement production and cosmetic, laboratory and technical applications; suitability and quantity must be checked for the specific formulation.
The 100 ml pack with a safety cap makes controlled handling of smaller volumes more practical; its duration cannot be expressed as a universal number of doses because this depends on the specific formulation and dilution. For repeated use, the consistent concentration is a practical advantage, while the result of pH adjustment can be checked by measurement according to the chosen procedure.
Why we added WoldoHealth to the PraveBio.cz range
We selected WoldoHealth for its focus on transparent documentation, clear product labelling (including concentrations) and declared manufacturing and testing in Germany.
For technical products, it is important to us that the composition, safe handling information and documents such as the safety data sheet (SDS) are readily available.
L(+)-dextrorotatory lactic acid 21%
L(+)-dextrorotatory lactic acid 21 % is a liquid raw material of food-grade quality for applications where a known concentration and control of acidity matter. In food production, lactic acid also carries the designation E 270; the L(+)-form commonly appears in food and other technological processes.
According to the manufacturer’s specification, it can serve as a raw material for pH adjustment, food and food supplement production, and cosmetic, laboratory and technical formulations; suitability and quantity must be checked for the specific product and formulation. When adjusting pH, check the change by measurement according to the specific formulation; for longer-term use, the repeatable 21% concentration is particularly practical because it allows you to follow the same working procedure each time.
The 100ml bottle with a safety cap is for working with smaller volumes. The number of uses cannot be determined without knowing the target concentration, mixture volume and required pH, so always follow a verified formulation and the relevant safety instructions.
For households that prefer straightforward compositions, working with one clearly defined raw material may be preferable to using a ready-made fragranced blend. 21% lactic acid is not a risk-free raw material: it irritates the skin and can cause serious eye damage, so careful handling is required.
Who it’s for:
- For preparing food formulations and adjusting pH – where the procedure is based on a known concentration and ongoing measurement.
- For experienced home and professional formulators – when preparing solutions and other mixtures according to a verified procedure.
- For laboratory and technical applications – as a liquid 21% L(+)-form of lactic acid.

Main benefits of L(+)-dextrorotatory lactic acid 21 %
- Precisely defined 21 % concentration – practical for procedures where you need to work with a known acid concentration from the outset.
- Food-grade quality – according to the manufacturer’s specification, it can serve as a raw material for appropriate food formulations; suitability and quantity must be checked for the specific product. It is not a product for direct consumption.
- L(+)-dextrorotatory form – a form commonly found in food production and other technological applications.
- pH adjustment – when handled correctly, it allows targeted adjustment of acidity; the result can be monitored by measuring pH.
- Liquid form – the clear to slightly yellowish liquid, with a mildly acidic characteristic odour, can be measured according to the chosen working procedure.
- 100 ml pack with a safety cap – a compact volume for more precise handling; actual duration depends on dilution, target pH and the volume of the mixture being prepared.
The main practical value lies in the combination of food-grade quality, the L(+)-form and a known 21% concentration. With repeated use, you can follow the same formulation and measurements rather than working with a raw material of unknown concentration each time.
Why pH measurement matters when working with lactic acid
Lactic acid 21 % is a raw material with a defined starting concentration, but the final pH of the mixture also depends on its overall composition, volume and the properties of the other substances present. The amount of acid added alone is therefore not enough to determine the final acidity safely.
Ongoing measurement with a suitable pH meter or appropriate indicators helps confirm whether the mixture remains within the range specified by the particular formulation. Work in small, controlled steps and always allow the entire formulation to mix evenly before making any further adjustment.
The measured pH value does not replace a verified working procedure, checks for material compatibility or safety instructions. For repeatable results, record the starting volume, quantities used and resulting value; do not use the 21% solution without knowing the requirements of the intended application.

FAQ
What is L(+)-dextrorotatory lactic acid 21 %?
It is a liquid carboxylic acid in the L(+)-form at a concentration of 21 %. This version is food grade and has applications including pH adjustment and food, cosmetic, laboratory and technical formulations.
What do L(+) and “dextrorotatory” mean?
They refer to a specific stereoisomeric form of lactic acid. For this raw material, the specification explicitly states the L(+)-form, which commonly appears in food and technological applications.
Is lactic acid the same as lactose or lactic acid bacteria?
No. Lactic acid is a chemical compound, while lactose is milk sugar and lactic acid bacteria are microorganisms. The word “lactic” therefore does not indicate lactose content or the presence of bacterial cultures.
Is this lactic acid food grade?
Yes. The specification states food-grade quality. This describes the quality of the raw material for appropriate applications, not the safety of a 21% concentration for direct drinking or skin contact.
Does lactic acid carry the designation E 270?
Yes. E 270 is the food additive designation for lactic acid. The specific method and quantity always depend on the type of formulation and the requirements of the application.
Can you drink 21% lactic acid directly?
This is not a drink or a food supplement for direct dosing. The source specification does not state any daily oral dose; for food applications, work only according to a verified formulation and the required final concentration.
What applications does it have in food production?
The listed applications include pH adjustment and use as a food raw material. There is no universal quantity because it depends on the formulation, volume and target pH.
Can it be used when making food supplements?
According to the manufacturer’s specification, the raw material can form part of food supplement production, but only in an appropriate formulation and quantity verified for the specific product. It is a formulation raw material, not a finished supplement or a product for direct consumption.
Can it be included in cosmetic formulations?
The cosmetic industry is one of the listed areas of application. For home formulation, you need to know the target concentration, final pH and compatibility of the entire formulation; the 21% solution is not for direct application to the skin.
Can it be used to prepare peels?
Lactic acid can serve as a raw material in some cosmetic formulations, including peels. This 21% concentration is not a finished peel; we do not recommend direct application to the skin without a professionally formulated recipe.
Is it appropriate for home use?
At home, it is appropriate only for experienced users working according to a verified formulation, label information, safety data sheet and specified dilution. For anyone without the necessary knowledge, a ready-made formulation with clear instructions is more appropriate.
Is 21% lactic acid “non-toxic” or completely safe?
That description would not be accurate. At a concentration of 21%, the stated hazards are H315 – causes skin irritation and H318 – causes serious eye damage, so careful handling is necessary.
Does it work as a disinfectant?
Lactic acid has applications and is studied in various food and technological processes, but this 21% raw material is not presented here as a ready-made disinfectant or biocidal product. For disinfection, choose a product made specifically for that purpose and follow its instructions.
Can it serve as an all-purpose surface cleaner?
The source specification does not provide universal instructions for cleaning every surface. As an acidic raw material, it can form part of technical formulations, but you must always check material compatibility, dilution and the specific procedure.
Can I mix lactic acid with other cleaning products?
Not without a verified chemical procedure. Do not combine it at random with other cleaning products; different active substances may react with each other or alter the final pH and safety of the mixture.
Do I need hand and eye protection when handling it?
Yes. Given the H315 and H318 classifications, avoid contact with skin and eyes and wear suitable protective gloves and eye protection, particularly when measuring and diluting.
What should I do if it gets into my eyes?
This substance carries a warning for serious eye damage. Immediately follow the instructions on the label and the safety information, rinse the eyes with clean water and seek professional medical help without delay.
What should I do after skin contact?
Rinse the affected area with plenty of water and follow the label and available safety information. Seek professional help if irritation is persistent or significant.
What should I do after accidental ingestion?
This is not a product for direct consumption. If accidentally swallowed, follow the label and safety information and contact a healthcare professional or poison information service; keep the packaging available during the consultation.
How should I store lactic acid?
Keep it in the original, properly closed bottle with the safety cap, out of reach of kids and positioned to prevent accidental tipping or contact with the eyes and skin. Follow the label on the specific pack for any additional storage conditions.
How long does a 100 ml pack last?
There is no universal number of doses. Duration depends on the target concentration, amount of mixture being prepared and required pH; with this type of raw material, it is more accurate to track consumption according to the specific formulation than by number of uses.
What colour, consistency and odour does it have?
It is described as a clear to slightly yellowish liquid with a characteristic mildly acidic odour. A marked change in appearance or damaged packaging is a reason to postpone use and check the condition of the pack.
How do I determine the correct dilution?
Determine dilution according to the starting 21% concentration, target concentration, volume and required pH. Without a specific application, there is no single universal ratio that can be recommended safely.
How do I know whether I have added the correct amount when adjusting pH?
Check the result with suitable pH measurement and work in small, controlled steps according to the formulation. The volume of acid added alone, without knowing the composition of the entire mixture, is not a reliable indicator of the final pH.
Is the 21% concentration ready to use without further dilution?
Not universally. 21 % is the starting concentration of this raw material; depending on the application, further dilution or incorporation into a formulation may be necessary. Direct use without knowing the target concentration is not appropriate.
How does it differ from citric acid from PraveBio.cz?
Citric acid from PraveBio.cz is a different carboxylic acid and usually comes in a solid, crystalline form, while this product is a liquid 21% L(+)-lactic acid. The choice depends on the specific formulation, required form and working procedure; the two do not have interchangeable 1:1 dosing.
How does it differ from a ready-made bathroom cleaner?
A ready-made bathroom cleaner has a pre-formulated composition and application instructions. By contrast, 21% lactic acid is a raw material for formulation and pH adjustment, so you need to control dilution, material compatibility and final pH yourself.
Is it appropriate for a vegan, gluten-free or lactose-free household?
For this specific raw material, the source page does not document certification or a separate claim for vegan, gluten-free or lactose-free status. We therefore do not treat these characteristics as verified parameters of the pack.
Can lactic acid be kept in a home with kids, and does the bottle have a safety cap?
The 100ml bottle has a safety cap, but 21% lactic acid is not for kids to handle on their own. Given the risk of skin irritation and serious eye damage, keep it out of reach of kids and leave handling to an adult familiar with the safe procedure.
Why choose WoldoHealth L(+)-lactic acid 21 %?
The main purchasing points are the clear 21% concentration, L(+)-form, food-grade quality and 100ml pack with a safety cap. You know in advance which form and concentration you are working with, which matters for both formulation and pH control.
