Salicylic Acid Powder

Salicylic Acid is a well-known beta hydroxy acid (BHA) widely used in skincare, pharmaceuticals, and cosmetics for its exfoliating, keratolytic, and anti-inflammatory properties. It is naturally derived from plants like willow bark but is more commonly produced synthetically for commercial use.

Water-Soluble Salicylic Acid refers to a modified form or encapsulated system of the classic beta-hydroxy acid (BHA) that allows it to be used in water-based formulations. Unlike traditional salicylic acid (which is oil-soluble), this version is ideal for formulators seeking to develop clarifying toners, gels, and serums without alcohol or oily solvents.

BENEFITS OF USING WATER-SOLUBLE SALICYLIC ACID:

• Exfoliates inside pores to help unclog sebum, debris, and dead skin

• Offers gentle yet effective acne and blackhead treatment

• Compatible with water-based systems – ideal for toners and gels

• Helps refine skin texture and reduce roughness

• Reduces inflammation and redness from blemishes

• May have less irritation potential due to slower or controlled release

• No need for alcohol or oil-based solvents for incorporation
