- INCI:Salicylic acid
- Composition:Salicylic acid
- Purity Grade:USP grade
- Appearance:Fine, white powder, odorless
- Preservation:Preservative-free
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).
Salicylic Acid Powder ≥99.5% USP Grade is a cosmetic-grade product that, in creams and solutions, can be used topically for treating several skin conditions that involve overgrowth of cells, scaling, calluses, warts, dandruff, etc. It is also effective for acne treatment and penetrates the skin to remove damaged cells clogging pores.

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.
