Water soluble salicylic acid powder

What is water soluble salicylic acid powder?

Salicylic acid is a fat-soluble organic acid. It is found in many plants, such as willow bark, and has both cosmetic and medicinal value. In the past few decades, as a very important active ingredient, it has been widely used in cosmetics and over-the-counter (OTC) drugs. In the treatment of skin diseases and the preparation of cosmetic product formulations, it is used to treat dandruff, acne, skin wrinkles, skin pigmentation, blemishes, freckles and other related skin disease symptoms. It is lipophilic and is a good exfoliant that can penetrate into the pores, dissolve dead skin cells, and enhance the vitality of skin cells. It promotes skin cell renewal, reduces fine lines, makes the skin smooth and delicate, and thus comprehensively improves the appearance and texture of the skin.
It is a white crystalline powder at room temperature. It has a slight odor. Generally speaking, it has the effects of acne removal, anti-inflammatory, antibacterial, pore reduction, anti-photoaging, whitening, and wrinkle removal. It is fat-soluble and slightly soluble in water. At 25°C, only 2.48g can be dissolved per liter of water. At the same temperature, 24.3g can be dissolved per kilogram of olive oil. There is an order of magnitude difference.
According to the hydration theory and the principle of penetration, cyclodextrin is easily soluble in water. When the stratum corneum cells are in a hydrated state, the cells will swell, causing the structural density to decrease, and the stratum corneum distribution coefficient of cyclodextrin will increase, thereby increasing the diffusion rate of the skin layer, making it easier to penetrate the stratum corneum of the skin (penetration enhancer), and promoting the chance of cosmetics penetrating the stratum corneum.

The difference between water soluble salicylic acid and salicylic acid:
The solubility of salicylic acid in water is very low, about 2g/L3. It is a fat-soluble organic acid, which means that it dissolves more easily in oil than in water. Due to its low water solubility, it is often used in care products for oily or mixed skin, such as cleansers, exfoliants, and anti-acne products. It is also used medically to treat acne and other skin diseases. Although it has good antifungal, anti-inflammatory, and anti-acne effects, it may cause some irritation to the skin due to its fat solubility, especially for sensitive skin. Under certain conditions, such as high temperature or low pH, it may decompose or lose its effectiveness.
Water soluble salicylic acid has been significantly improved in solubility through special technical treatments, such as the use of water-soluble polymers such as cyclodextrin, and can be stably dissolved in water. Due to its good water solubility, it is more suitable for water-based cosmetic formulations, such as lotions, creams, and water-based agents. It can be more evenly distributed in the product, improving the stability and use effect of the product. By improving the water solubility of salicylic acid, its irritation and toxic side effects can be reduced while maintaining its pharmacological activity. This improvement makes it more suitable for use in cosmetics for sensitive skin and long-term use. By forming hydrogen bond complexes with water-soluble polymers, it shows good stability in high and low temperature changes and pH changes, ensuring its high efficiency and safety in cosmetic or shampoo formulations.

Uses:

Its main uses are to remove acne, regulate water and oil balance, whiten, and treat superficial fungal diseases of the skin. Water soluble salicylic acid is mainly used in multiple industries such as skin medicines and skin care products.

Skin care field:
1. Acne removal: It can penetrate deep pores and dissolve the old accumulated stratum corneum in the pores, thereby improving the problem of pore blockage, thus blocking the formation of acne, removing acne and cleaning the skin;
2. Regulating water and oil balance: It can regulate the rate of oil secretion by sebaceous glands, thereby slowing down the oil secretion of the skin and regulating the water and oil balance;
3. Whitening: It can inhibit the production of tyrosinase and reduce the secretion of melanin, thereby whitening the skin. At the same time, it has exfoliation properties, which can remove excess skin stratum corneum and generate new skin, thereby achieving a certain whitening effect;
4. Treatment of superficial fungal diseases of the skin: If the superficial skin is infected with fungi such as Microsporum, Trichophyton, Candida and Malassezia, the pathogenic fungi parasitic on keratin tissue can be metabolized by peeling off the stratum corneum of the skin, thereby achieving the treatment effect.
