Wholesale Cosmetic Grade Raw Materials Salicylic acid
Products Description
- PH Value:PH of saturated solution: 2.4
- Solubility:Water: about 0.2% at 20oC, about 1.7% at 75oC (by adding about 5% of sodium phosphate or another neutral salt, solubility of salicylic acid in water is increased to about 1.8%). Alcohol (ethanol): about 14% in pure ethanol, about 0.5% in 20% ethanol. Propylene glycol: about 3-6%. Glycerin: about 1.6%. Octyldodecanol: about 15-20%
- Storage:Store light-protected at a cool and dry place
- Raw Material Source:Sodium phenoxide and carbon dioxide.
- Manufacture:Salicylic acid is prepared from dry sodium phenoxide in a stream of carbon dioxide. It is further purified by crystallizing the sodium salicylate from water at a temperature not exceeding 20 deg C.
- GMO:GMO-free (does not contain plant-derived components)
- Vegan:Does not contain animal-derived components
Organic beta hydroxy acid (chemical name: 2-hydroxybenzoic acid), occurs naturally in various plants. Melting Point: 159°C (318°F).

Benefits
*Medical field
- Antipyretic and analgesic drugs: It is the main raw material for synthesizing aspirin (acetylsalicylic acid). Aspirin is a commonly used antipyretic, analgesic, and anti-inflammatory drug that can be used to relieve headaches, toothaches, neuralgia, muscle pain, and prevent cardiovascular diseases.
- Treating skin diseases: It has the ability to dissolve keratin and is a type of keratin softener that can be used to treat skin diseases such as acne, seborrheic dermatitis, psoriasis, and ichthyosis. By dissolving keratin in the stratum corneum of the skin, the stratum corneum is shed, promoting skin metabolism, and also having certain antibacterial and anti-inflammatory effects.
*Cosmetics field
- Exfoliation: It can remove the accumulated aging keratinocytes on the surface of the skin, promote the renewal of skin cells, make the skin smoother and more delicate, and improve the texture and color of the skin.
- Oil control and acne removal: It can penetrate deep into pores, dissolve oil and dirt inside pores, prevent pore blockage, and has a certain therapeutic effect on treating common acne. At the same time, it also has a certain anti-inflammatory effect, which can alleviate the redness, swelling, and inflammation caused by acne.
*Industrial sector
- As a preservative: Salicylic acid has certain antibacterial properties and can be added as a preservative to industrial products such as rubber and resin to prevent microbial erosion and extend the product's service life.
- Synthetic dyes and fragrances: are important intermediates for synthesizing various dyes and fragrances. Through chemical reactions, salicylic acid can be converted into various compounds with specific colors and aromas, which are widely used in industries such as textiles, printing and dyeing, and fragrances.
Application
Peels and exfoliant products. Anti-acne products (max. 2%). Anti-dandruff products (max 3%). Wart-removing products (max. concentration depends on type of plaster vehicle used).
Formulation Guide
Typical use level 0.5-3%. Typically, it is added to the water phase of formulas but it is only slightly soluble in water. If used at concentrations higher than 2%, octyldodecanol or propylene glycol should be used as solvent. Salicylic acid can be added also in powder form to a finished cream or lotion without dissolving it first in water or another solvent.
