Sodium Citrate and Sodium Hydroxide are both commonly used as ph adjuster ingredients. While they share the same primary function — regulates the acidity or alkalinity of the product to optimal levels — they differ in chemical structure, skin compatibility, and performance. Both are found in AHA/BHA exfoliants, vitamin C serums, toners, and cleansing gels, but their suitability varies based on formulation goals.

Sodium Citrate vs Sodium Hydroxide: Key Differences

Sodium Citrate is included for maintaining optimal pH for skin compatibility and ingredient stability, contributing to ensuring product efficacy, comfort on skin, and long-term stability. Found in exfoliants, acid treatments, cleansers, and toners, best for all water-based formulations requiring pH control.

Sodium Hydroxide is added for maintaining optimal pH for skin compatibility and ingredient stability, helping with ensuring product efficacy, comfort on skin, and long-term stability. Found in exfoliants, acid treatments, cleansers, and toners, suited for all water-based formulations requiring pH control.

When to Choose Sodium Citrate or Sodium Hydroxide

Choose Sodium Citrate for maintaining optimal pH for skin compatibility and ingredient stability. Effective in AHA/BHA exfoliants, vitamin C serums, toners, and cleansing gels.

Choose Sodium Hydroxide for maintaining optimal pH for skin compatibility and ingredient stability. Works well in AHA/BHA exfoliants, vitamin C serums, toners, and cleansing gels.

Sodium Citrate & Sodium Hydroxide: Skin Type Considerations

Sodium Citrate suits all water-based formulations requiring pH control, while Sodium Hydroxide works better for all water-based formulations requiring pH control. Performance varies with concentration, product type, and other active ingredients.
