SY-OCT Anti-Dandruff Itch Relief Agent

Product Name: SY-OCT Anti-Dandruff and Anti-Itch Agent (Piroctone Olamine)

Characteristics and Efficacy

• Used as an anti-dandruff and anti-itch agent in rinse-off hair care products

• Excellent anti-itch effect of the anti-dandruff and anti-itch agent

• Broad-spectrum fungicidal and mold-killing effects, effective in treating athlete's foot and hand fungus
• Can be used as a preservative in cosmetics, a bactericide in soaps, and has thickening properties
• Highly effective anti-dandruff product with low toxicity and low irritation
• Fundamentally blocks external channels of dandruff formation through bactericidal and antioxidant effects, effectively eliminating dandruff and relieving scalp itch
• Highly effective anti-dandruff with low toxicity and low irritation, widely used in anti-dandruff shampoos, hair tonics, and conditioners
• SY-OCT Anti-Dandruff and Anti-Itch Agent is soluble in surfactant systems, a significant advantage over similar anti-dandruff products like ZPT. Easily soluble in ethanol (10%), soluble in surfactant-containing aqueous solutions or ethanol/water mixtures (1%-10%), slightly soluble in water (0.05%) and oil (0.05%-0.1%). Solubility is highly dependent on pH; generally, solubility is greater in neutral or weakly alkaline aqueous solutions.
• The typical addition amount of SY-OCT Anti-Dandruff and Anti-Itch Agent is 0.1%-0.75%, while in hair tonics and conditioners, the addition amount is reduced to 0.5%-0.1%.
• SY-OCT Anti-Dandruff and Anti-Itch Agent remains stable within a pH range of 3-9. Under neutral conditions, it exists in the form of free acid, with a pKa of 7.4.

21. Solubility

SY-OCT Anti-Dandruff and Anti-Itch Agent is soluble in surfactant systems, a significant advantage over similar anti-dandruff products like ZPT. Easily soluble in ethanol (10%), soluble in surfactant-containing aqueous solutions or ethanol/water mixtures (1%-10%), slightly soluble in water (0.05%) and oil (0.05%-0.1%). Solubility is highly dependent on pH; generally, solubility is greater in neutral or weakly alkaline aqueous solutions.

21. Compatibility with Cosmetic Ingredients

SY-OCT Anti-Dandruff and Anti-Itch Agent has good compatibility with various cosmetic ingredients. It is particularly noteworthy that the anionic active component SY-OCT Anti-Dandruff and Anti-Itch Agent can be mixed with various cationic surfactants (quaternary ammonium salts) and cationic active components. In some cases, this combination can even increase the solubility of SY-OCT Anti-Dandruff and Anti-Itch Agent, which is an important indicator of its superior compatibility compared to other anti-dandruff and anti-itch agents like ZPT, MDS, CLM, etc.

At addition levels below 0.5%, except for formaldehyde, SY-OCT Anti-Dandruff and Anti-Itch Agent can be combined with aldehyde and ketone-containing fragrances. Although SY-OCT Anti-Dandruff and Anti-Itch Agent may change color when in contact with metals like copper and iron, the color change is light yellow and does not affect its efficacy. In practical production, deionized water can be used, and measures such as preventing heavy metal ions and using dyes to mask the color can be taken to overcome this issue.

21. pH Value Influence

SY-OCT Anti-Dandruff and Anti-Itch Agent remains stable within a pH range of 3-9. Under neutral conditions, it exists in the form of free acid, with a pKa of 7.4.

21. Thermal Stability

SY-OCT Anti-Dandruff and Anti-Itch Agent has excellent thermal stability. During production, occasional temperatures exceeding 80°C will not affect its performance. Additionally, shampoos containing SY-OCT Anti-Dandruff and Anti-Itch Agent (at pH 5.5 and pH 7.0) can be stored at 40°C for one year.

21. Light Stability

Under direct ultraviolet light, the active components of SY-OCT Anti-Dandruff and Anti-Itch Agent may decompose. Therefore, it is important to store SY-OCT Anti-Dandruff and Anti-Itch Agent away from light as much as possible.

21. Effect on Viscosity

The addition of SY-OCT Anti-Dandruff and Anti-Itch Agent can increase the viscosity of many surfactant systems.
