Hydroxyacetophenone — powder, Global — MakeYourSkin

About this material

Hydroxyacetophenone is an Antioxidant / preservative booster supplied by MakeYourSkin as powder / liquid for professional cosmetic formulation. Used worldwide across mainstream cosmetic formulation, it is valued for microbial control / preservation support.

What is Hydroxyacetophenone?

Hydroxyacetophenone is supplied under the INCI / technical name Hydroxyacetophenone and carries CAS number 99-93-4.

It belongs to the Antioxidant / preservative booster group and is derived from global. The material reaches you as powder / liquid. It is an established cosmetic raw material with mature supply and well-understood formulation behaviour.

Key Properties & Benefits

  • Microbial control / preservation support
  • Contributes to a preservation system that must still be validated by challenge testing on the finished product.

Uses & Applications

Hydroxyacetophenone is used in every water-containing format — cleansers, toners, serums, creams, masks and hair care.

Typical applications from the catalogue record: Water-containing cosmetics.

As a formulation essential it is specified by function rather than by claim, and the level is set by the performance the formula needs rather than by a marketing target.

How to Use — Recommended Use Level

Typical use level 0.3–1%
Recommended pH any
Addition phase Water phase
Solubility Water-soluble. Disperse into the water phase with stirring; avoid prolonged high heat where the material is heat-sensitive.

General rule: always begin at the lower end of the range, confirm the level against the supplier technical data sheet, and validate stability, pH, colour, odour and preservative efficacy on the finished formulation before scaling up.

Regulatory Note

Preservatives are permitted only if they appear on the destination market's positive list, and only within the stated maximum and conditions of use. Levels apply to the total from all sources in the formula. Confirm the current entry and support the finished product with challenge testing.

Supplier diligence required: Restricted-use / market-specific preservative limits must be checked.

Sold as a cosmetic raw material for professional formulation. A published INCI name does not by itself authorise use: the buyer is responsible for confirming permitted status, maximum concentration, restrictions by product type, labelling and claim rules in every market the finished product is sold in. In India, cosmetics fall under the Drugs and Cosmetics Act 1940 and the Cosmetics Rules 2020 administered by CDSCO, with BIS standards (including IS 4707 Part 2) listing restricted substances. The EU applies Regulation (EC) No 1223/2009 and its Annexes; the United States applies the FD&C Act as amended by MoCRA; Korea, Japan and China operate their own positive lists and functional-cosmetic frameworks. Every finished product needs its own safety assessment.

Disclaimer & Caution in Use

For external cosmetic use in professionally formulated products only. This is a concentrated raw material, not a finished cosmetic, and it is not intended for undiluted application to skin, for ingestion, or for any medicinal purpose. Wear gloves and eye protection when handling, avoid raising dust with powders, and keep out of reach of children and pets. Always run a patch test on the finished formulation, and validate stability, compatibility, pH and preservative efficacy before sale. Information supplied is offered in good faith as formulation guidance and does not constitute a safety assessment, a regulatory approval or a medical claim.

Fine powder — avoid generating and inhaling dust. Use local exhaust ventilation or a suitable respirator when weighing, and wet the powder into the formulation phase rather than dry-blending in open air.

Restricted or high-diligence material. Confirm your legal position in every destination market before ordering. Supplied on the understanding that the buyer holds responsibility for compliant use, permitted concentration and claim wording.

How to work with it

1 Check the phase before you weigh

The specification's Add at row is the one to read first. Water-phase materials added to a hot oil phase are the most common reason a batch separates.

2 Hold the pH inside the stated range

Measure the finished product, not the premix. Outside the range the activity drops away and, for some materials, the degradation route is what causes complaints.

3 Start at the bottom of the use level

Then work up through stability and compatibility testing. Higher is not better, and the destination market's limit may sit below your formulation ceiling.
