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
- Can be used for skin peels, anti-dandruff products, and in products for oily, acneic and/or blemished skin
- Ideal for making products that need higher concentrations of salicylic acid
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.
