HDK is a registered trademark ofWacker Chemie AG.

WACKER has been producing and

r ning its brand of HDK pyrogenicsilica for ov r 40 y ars. Our int grat d manufacturing protocols, statisticalproc ss control and highly ffici ntr actor dynamics produc xc p -tionally pur grad s of inorganic,pyrog nic silica. Th s grad s ar

sp cially w ll-suit d for p rsonalcar and cosm tics applications.

Fascinatingly V rsatil

Although HDK pyrogenic silica is anestablished and highly successful product,WACKER continues to push forward withits R&D to seek new potential solutionsto further boost product performance

and quality. The exclusive selection of

both hydrophobic and hydrophilic HDK grades o ers highly versatile and com -prehensive solutions for a wide rangeof personal care and cosmetic appli-cations.

HDK is produc d at multipl sit s by an int grat d, ci nt and nvi ron-m ntally compatibl proc ss that sav s

n rgy and raw mat rials.

Hydrophilic HDK with a LargSurfac Ar a

The production parameters are re-sponsible for the excellent properties ofhydrophilic, pure and odorless HDK .

Pyrogenic silica is formed by hydrolysisat over 1,000 C. This is achieved byintroducing chlorosilanes into an oxyhy-drogen ame, producing SiO 2 primaryparticles about 550 nanometers (10 9 m)in size. In the ame, the primary particlesfuse together permanently to form largeunits, o r aggregates (1001,000 nm insize). That is to say, individual primaryparticles only exist in the reaction zoneitself.

On cooling, the aggregates mechanicallyentangle to form agglomerates, knownas tertiary structures. The aggregateshave sizes in the range of microns. HDK has a very high speci c surface area(BET) because of the small diameters ofits primary building blocks. The primaryparticles that are fused together in theaggregates nally arrange themselvesinto agglomerates. This inherently largesurface area-to-mass ratio causesintense interparticulate interactions,which are the result of attractive disper-sion and dipolar forces. And that isprecisely the reason for the outstandingproperties of HDK .

HDK CERTIFIED QUALIT Y

GRASPyrogenic hydrophilic silica is generallyregarded as safe material accordingto FDA 182.90.

ReACH complianc statusHerewith we con rm that HDK is incompliance with the EC Regulation1907/2006 (REACH).

HDK was successfully registered inthe silicon dioxide substance groupaccording to the REACH regulation onthe registration, evaluation, authoriza-tion and restriction processes for chemi-cal substances. This was announcedby the European Chemicals AgencyECHA in mid-March 2009.

Complianc Cosm tic Dir ctivHDK complies with Regulation 1223/2009 (recast of the Cosmetic Directive76/768/EC and all its amendments).

The product neither contains any ofthe restricted compounds included in

Annex III as per recipe nor are any CMRcat. 1 or 2 compounds intentionallyintroduced.

HDK has wide uses in cosmeticsand personal care products for itsvariety of specific properties.

Rh ology controlHDK increases viscosity and impartsthixotropy. As a gelling agent, HDK modi es the viscosity of oils, waxesand emulsions.

S dim ntation and s parationHDK delays or prevents settlingof pigments and powders(in suspensions).

In creams, lotions, lipstick andfoundation products, HDK improvesstability and structure.

HDK stabilizes formulations byreducing sensitivity to temperature,electrolytes and pH.

Fr - ow and anticaking additivHDK improves the free-flow of powders.

Applicat ions

Color Cosm ticsIn foundations, eyeliners und mascara,HDK regulates consistency,controls viscosity and prevents theagglomeration of color pigments.

PowdersHDK enhances the free flow of powders.

Nail lacquersHDK assures uniform distributionof pigments, reduces sedimentationand allows rheology control.

LipsticksHDK acts as a thickener andimproves the consistency of lipsticks.

HDK facilitates the uniform distribu-tion of pigments and enhances thermalstability.

Ant ip rspir antsHDK stabilizes suspensions, preventsthe agglomeration of active ingredientsand ensures their uniform distribution;it increases the viscosity of creams andsticks; either hydrophilic or hydrophobicHDK can be used.

PACKAGING

Pall ts with Pap r Bags HDK is available in multilayer valvedpaper bags which contain 10 kg ofproduct. The bags are delivered onpallets which are shrink-wrapped witha polyethylene foil to protect the HDK against moisture. This allows theproduct to be stored without anymoisture uptake. If the shrink foil isdamaged or single bags are removed,care must be taken to protect theremaining bags/individual bags againstmoisture by either wrapping in plasticor other appropriate measures.

Palletized and shrink-wrapped forgood product protection, storageand handling

Three-ply paper for added strength Bags are disposable

Big bags The big bag solution is available for mostHDK grades, a woven polypropylenebag containing 150200 kg of product,depending on the respective bulk densityof the product. Big bags are deliveredon a pallet shrink-wrapped with a poly-ethylene lm to protect against moisture.
