ZLEY® HPA – Hydroxyphenyl Propamidobenzoic Acid (CAS 697235-49-7):

鎮静・かゆみ止め効果を持つNK1R拮抗薬

製品概要

ZLEY® HPA (INCI: Hydroxyphenyl Propamidobenzoic Acid), also known as Dihydroavenanthramide D, is a potent neurokinin-1 receptor (NK1R) antagonist. By competitively binding to NK1R, it blocks the SP/NK1R signaling pathway, inhibits mast cell degranulation, and reduces the release of pruritogenic mediators such as histamine. This mechanism provides rapid relief from skin itching and discomfort, delivering effective soothing and anti-itch benefits. ZLEY® HPA also offers additional benefits, including barrier repair and photoprotection.

ZLEY® is a professional supplier of Hydroxyphenyl Propamidobenzoic Acid (CAS 697235-49-7), providing stable quality, technical support, and global delivery covering over 60 countries.

ZLEY® HPA – Frequently Asked Questions (FAQ)

Q1: What is the mechanism of action for ZLEY® HPA?

A: ZLEY® HPA is a neurokinin-1 receptor (NK1R) antagonist. It works by competitively binding to the NK1R, which blocks the substance P/NK1R signaling pathway. This inhibition prevents mast cell degranulation and reduces the release of itch-inducing mediators, including histamine. This targeted mechanism provides rapid relief from itching and discomfort, addressing the root cause of pruritus rather than just masking symptoms.

Q2: How does ZLEY® HPA compare to traditional anti-itch ingredients?

A: Traditional anti-itch ingredients often work through broader mechanisms—such as general anti-inflammatory effects or local anesthetics—which can be less targeted or cause side effects. ZLEY® HPA’s mechanism is specifically targeted at the NK1R pathway, making it highly effective for pruritus relief while maintaining a favorable safety profile. Additionally, HPA provides barrier repair and anti-photoaging benefits beyond just itch relief, offering multiple skin benefits in one ingredient.

Q3: What is the recommended usage level for ZLEY® HPA?

A: The recommended usage level is ≤ 2.0% for both full-body and eye-area leave-on products. Safety assessments confirm that this concentration is safe under normal, reasonable, and foreseeable conditions of use.

Q4: Is ZLEY® HPA suitable for sensitive skin?

A: Yes. ZLEY® HPA is specifically known for its soothing and anti-itch properties, making it highly suitable for sensitive skin formulations, baby products, and post-sun repair products. Its mechanism of action targets the underlying causes of skin irritation, making it particularly beneficial for compromised or reactive skin.
