Product advantages
1.The 40% water-soluble salicylic acid produced by Shandong Binzhou Zhiyuan Biotechnology compared with similar products in the domestic and international markets. It has a lower pH value ranging from 3.5 to 4.5, and our product is pure salicylic acid, not sodium salicylate.
2.By employing unique supramolecular technology, salicylic acid can be encapsulated using microencapsulation techniques, enhancing its water solubility and allowing for its stable incorporation into cosmetic formulations.
3.The high content of salicylic acid in the formulation can meet the majority of customer demands.
Application
1.Skincare: Water-soluble salicylic acid is commonly used in various skincare products such as facial cleansers, toners, masks, and acne treatments. It has exfoliating and pore-cleansing properties, helping to reduce the formation of pimples, blackheads, and whiteheads, and improving the texture of the skin.
2.Scalp care: Water-soluble salicylic acid can also be used in scalp care products like anti-dandruff shampoos and scalp treatments. It helps to reduce the production of dandruff, regulate scalp oil secretion, and provide a refreshed scalp environment.
Nail care: Water-soluble salicylic acid is often used in nail care products such as exfoliating agents and nail whitening products. It helps to remove the dead skin layer on the nail surface, smoothen the nail surface, and make the nails appear brighter.
Pharmaceutical field: Water-soluble salicylic acid also finds applications in the pharmaceutical field. For example, it can be used in the treatment of certain skin conditions such as psoriasis and common warts. Additionally, salicylic acid is used as a drug carrier, playing a role in drug delivery and transport systems.

Storage precautions
Due to its irritant properties, inhalation of salicylic acid can cause coughing and chest discomfort. It is also irritating to the eyes and prolonged exposure can lead to eye damage. Long or repeated skin contact can cause dermatitis and even burns. Ingestion of salicylic acid may result in gastrointestinal irritation, tinnitus, and kidney damage.
To store 40% water-soluble salicylic acid, it should be kept in a cool, well-ventilated area with strict containment measures. It should be kept away from ignition sources, heat, and direct sunlight. It should be stored separately from oxidizing agents and alkalis, and mixing should be avoided. The storage area should be equipped with appropriate firefighting equipment and emergency response devices for leaks.
During handling, it is important to work in a closed system with local exhaust ventilation and explosion-proof ventilation systems and equipment to prevent the release of dust into the air. Operators must undergo specific training and strictly follow operating procedures. It is recommended for operators to wear self-contained breathing apparatus, chemical safety goggles, impermeable work clothing, and rubber gloves.
First Aid:
- Inhalation: If inhaled, move the patient to fresh air.
- Skin contact: Remove contaminated clothing and thoroughly rinse the skin with soap and water. If discomfort persists, seek medical attention.
- Eye contact: Separate eyelids and rinse with flowing water or saline solution. Seek immediate medical attention.
- Ingestion: Rinse mouth and do not induce vomiting. Seek immediate medical attention.
Content Determination Method
1.UV Spectrophotometric Method:
Take an appropriate amount of the sample and accurately weigh it. Dilute with a suitable solvent to obtain a solution containing 20μg of the sample per 1ml (Note: Ensure the sample is fully dissolved during the content determination). Use a solvent solution as a blank control. Measure the maximum absorbance and calculate the content, which should not be less than 40.0%.
2.Titration Method:
Take approximately 1.0g of the sample and accurately weigh it. Add 25ml of neutral diluted ethanol (indicated by phenolphthalein showing neutrality). Ultrasonicate for 30 minutes, add 3 drops of phenolphthalein indicator, and titrate with sodium hydroxide solution (0.1mol/L). Each 1ml of sodium hydroxide solution (0.1mol/L) is equivalent to 2.762mg of salicylic acid. The content of salicylic acid should not be less than 40.0%.
Product Features
As a chemical skin peeling agent, 40% water-soluble salicylic acid has many functions such as lightening pigmentation, shrinking pores, removing fine wrinkles and improving aging caused by sun exposure. But salicylic acid is a fat-soluble organic acid that is basically insoluble in water. Solutions to the solubility of salicylic acid in water:
