Buyer decision path
Why Evaluate NOYAIN HP100?
For a B2B raw-material decision, purity alone is not enough. HP100 is positioned to make supplier qualification, laboratory screening and commercial purchasing easier.
01
Consistent ≥99% Quality
A defined ≥99.0% content specification gives formulation and incoming-QC teams a clear acceptance benchmark.
What it means for you: easier raw-material comparison and qualification.
02
Controlled Key Impurities
The specification includes controls for Phenol and o-Dichlorobenzene at ≤10 ppm each, together with other quality parameters.
What it means for you: more information than assay alone when reviewing suppliers.
03
Test Before You Scale
Samples and current-batch documentation are available for dissolution, compatibility and stability evaluation.
What it means for you: reduce purchasing risk before moving to commercial quantities.
04
From Lab to Bulk Supply
Standard packaging includes 1 kg aluminum foil bags and 25 kg drums for evaluation and commercial purchasing.
What it means for you: a clear path from screening to scale-up.
Formulation Value
What Does Hydroxyacetophenone Do in Cosmetics?
Hydroxyacetophenone is a multifunctional cosmetic ingredient used primarily for antioxidant and skin-conditioning support. It is also commonly evaluated as a preservative booster to help strengthen broader preservation systems in cosmetic formulations.
Antioxidant & Skin-Conditioning Support
Hydroxyacetophenone is recognized in cosmetic ingredient safety literature for antioxidant and skin-conditioning functions.
It can be evaluated when formulators need a multifunctional ingredient that supports overall formula design rather than a single-purpose additive.
Preservative-Boosting Support
HP100 can be evaluated as part of a broader preservation strategy together with the selected preservative system, formula pH, manufacturing hygiene and packaging.
Supplier screening data indicate antimicrobial activity against selected microorganisms, supporting early-stage technical evaluation.
Formulation note: Preservation performance depends on the complete finished formula. Validate the final system through appropriate stability and preservative efficacy testing.
Project Fit
Is HP100 a Fit for Your Project?
Consider HP100 if you are:
- developing a cosmetic formula that needs antioxidant support;
- evaluating a preservative booster within a broader preservation system;
- looking for ≥99% Hydroxyacetophenone (CAS 99-93-4);
- comparing suppliers by purity, impurity control and batch documentation;
- testing a new formulation before commercial scale-up;
- preparing a supplier qualification package that requires COA, specification and SDS.
