Malic Acid

Malic Acid (AHA – Alpha Hydroxy Acid)

Malic Acid is a naturally occurring alpha hydroxy acid (AHA) found in fruits like apples and cherries. It is used in cosmetics and personal care products for its gentle exfoliating, hydrating, and pH-adjusting properties. Milder than glycolic or lactic acid, malic acid provides a gradual, surface-level exfoliation, making it suitable for sensitive or dry skin and layered acid formulations.

BENEFITS OF USING MALIC ACID:

• Exfoliates dead skin cells for smoother, brighter skin

• Improves skin hydration by enhancing natural moisturising factor (NMF) production

• Refines texture and tone with low irritation risk

• Promotes gentle cell turnover for more radiant skin

• Helps clear clogged pores and reduce blemishes

• Functions as a pH adjuster in acidic formulations

• Pairs well with other AHAs and BHAs for synergistic exfoliation

INCI: Malic Acid

CAS No.: 6915-15-7
Appearance: White crystalline powder
Solubility: Soluble in water and alcohol
Recommended Usage Rate: 0.5–5% (in exfoliants or pH adjustments)
pH Range for Activity: 3.0–4.5
Charge Type: Anionic (acidic compound)

FORMULATION TIP:

• Dissolve in water phase (warm or room temperature) before emulsification.

• Works best in low pH formulations—combine with glycolic or lactic acid for broader exfoliation spectrum.

• Can be used as a pH adjuster in AHA-based products.

• Use with chelating agents (e.g., EDTA) if needed to stabilize in the presence of metal ions.

• Best added during the cool-down phase if formulating with heat-sensitive ingredients.

APPLICATIONS:

• Exfoliating toners and peels

• Brightening masks and serums

• Anti-aging creams and gels

• Acne treatment products

• Scalp exfoliants and hair tonics

• Foot scrubs and callus softening products

PRECAUTIONS:

• For external use only

• May cause mild stinging or irritation—patch test recommended

• Use broad-spectrum SPF during use, as AHAs increase sun sensitivity

• Store in a cool, dry place, sealed tightly to avoid moisture exposure

• Check regional regulations for maximum allowable use in leave-on vs. rinse-off products

Malic Acid offers a balanced approach to exfoliation—strong enough to visibly improve skin texture, yet gentle enough for sensitive formulations. Its ability to hydrate while refining makes it a valuable addition to glow-enhancing and anti-aging cosmetic lines.
