Performance
Liquid Crystal Emulsification and Mildness Evidence
AC-PCP SV combines emulsification power, broad pH compatibility, skin feel and controlled impurities.
Oil Phase Challenge
A 1% use level can emulsify up to 80% oil phase in the tested mixed-oil system.
Broad pH Compatibility
AC-PCP SV maintains stable viscosity across a broad pH range with common pH adjusters.
Natural-Origin Formulation Support
Derived from palm-based sources and assessed according to ISO 16128 natural-origin criteria.
Liquid Crystal Structure
Layered liquid crystal organization can form a stabilizing barrier around droplets, supporting long-term stability, smoother application and controlled release of active ingredients.
Skin-Feel Advantage
AC-PCP SV provides favorable thickness, extensibility and moisturizing sensory performance in cream formulations.
High Compatibility
Highly compatible with ethanol and electrolyte-containing ingredients.
SPF and Sun-Care Relevance
AC-PCP SV supports SPF performance and sun-care emulsions where oil-phase and filter stability are important.
Application
Application and Processing Guide
Use AC-PCP SV with appropriate heating, emulsifier balance and final stability verification in the finished formulation.
- How to Use Prepare a pre-dispersion in either the oil phase or an aqueous solution. It is recommended to first form a milky dispersion in hot water, then mix it with the remaining water-phase ingredients before proceeding to the next step.
- Choose dosage by role Use 0.3-1.0% as a co-emulsifier or 1.3% and above as a primary emulsifier with co-emulsifier support.
- Validate oil load and pH Confirm emulsion stability, viscosity, pH, oil-phase load, active compatibility and packaging behavior before scale-up.
- Use in mild skin-care systems Prioritize sensitive-skin, baby-care, sun-care and premium facial-care formulas where mildness and silky skin feel are important.

FAQ
AC-PCP SV FAQ
Answers to common buyer questions about dosage, process, mildness, pH, documents and formulation use.
What is AC-PCP SV?
AC-PCP SV is an anionic oil-in-water emulsifier with INCI name Potassium Cetyl Phosphate. It is used to support stable, mild, silky O/W emulsions.
How much AC-PCP SV should be used?
Use AC-PCP SV at 0.3-1.0% as a co-emulsifier. When used as the main emulsifier, use 1.3% or above and pair it with suitable co-emulsifiers as needed.
Should AC-PCP SV be added to the water phase or oil phase?
AC-PCP SV may be added to either the water phase or oil phase, but adding it to the warm water phase is preferred.
Why is AC-PCP SV considered for sensitive-skin or baby-care formulas?
Its anionic phosphate chemistry, liquid-crystalline emulsion support and controlled phosphate-impurity specification make it suitable for evaluation in sensitive-skin and baby-care formulas. Confirm suitability through finished-formula stability, tolerance and safety testing.
What documents are available for AC-PCP SV?
TDS, SDS/MSDS, specification, COA sample, formulation guideline and declaration documents can be requested for quality and formulation review.
