Succinic Acid

Product Description

Direct factory supply of high-purity Succinic Acid (CAS 110-15-6), a C4 dicarboxylic acid produced via fermentation or synthetic crystallization routes. Each batch is COA-traceable for accountable B2B cosmetic and personal-care procurement.

Butanedioic acid buffers aqueous systems near pH 4–5.5 while delivering antioxidant, antimicrobial, and mild keratolytic activity. Its water solubility (~83 g/L) exceeds many cosmetic organic acids, easing incorporation without sensory drag.

Formulators specify succinic acid for acne-prone toners, gentle exfoliating serums, and clean-beauty buffers where dicarboxylic acids replace stronger AHAs in sensitive-skin clarity lines.

Key Benefits & Applications

Succinic Acid delivers antimicrobial clarity, gentle resurfacing, and pH buffering in acne, antioxidant, and sensitive-skin aqueous systems.

• Clarifies blemish-prone skin via antimicrobial action in acne toners and spot-care gels.
• Supports antimicrobial clarity in water-based systems without the sting of stronger AHAs.
• Regulates sebum output in oily-skin essences and clarifying water-based gels.
• Scavenges ROS to support antioxidant defense in mature-skin daily serums.
• Buffers pH and humectant retention in aqueous formulas near skin-friendly pH 4–5.5.
• Enables mild keratolytic resurfacing for smoother texture in sensitive-skin systems.

Formulation Guidelines

Use Succinic Acid as a multifunctional dicarboxylic acid active and pH buffer; follow solubility and pH guidance below.

• Use at 0.5–5.0% w/w in toners, serums, cleansers; typical 1–3% for clarity actives (Typical).
• Pre-dissolve in water phase; fully soluble at typical cosmetic use levels (Typical).
• Optimal activity near pH 4.0–5.5; compatible with niacinamide and zinc salts (Typical).
• Chelates metal ions; improves stability in hard-water and oxidation-prone formulas (Typical).
• Suitable for masks, essences, and scalp clarifying systems at 1–2% (Typical).
• Synergy: Layer Hyaluronic Acid with succinic acid in water-based serums to stack humectancy and gentle resurfacing at pH 4–5.5.
