PROCETYL AWS
INCI Name: PPG-5 Ceteth-20
PROCETYL AWS is an alcohol and water soluble nonionic liquid surfactant. Chemically,
the material is a saturated, mixed alkoxy ether of cetyl alcohol. This composition gives
the ingredient tremendous multi-functionality, conferring to it properties as an emollient,
fragrance solubilizer, humectant, plasticizer, emulsifier and wetting agent. The resultant
composite of highly desirable characteristics renders PROCETYL AWS extremely useful
in the formulation of bath oils, shampoos, clear gels and other hydroalcoholic systems.
PROCETYL AWS is produced by reacting cetyl alcohol with a mixture of ethylene oxide
and propylene oxide. What is crucial here is the choice of stoichiometry—an optimum
ratio of components specifically selected to yield an optimized mixed alkoxy
heteropolymer.

Like other ethoxylates and propoxylates (materials formed by the reaction of fatty
compounds with either ethylene or propylene oxide), PROCETYL AWS is classified as
an ether. As a mixed ether, it shares certain physical and performance characteristics
inherent to each. Acquiring its fluidity from the propylene oxide adduct and its water
solubility from that of the ethylene oxide, PROCETYL AWS possesses a unique
character which manifests itself primarily in the form of enhanced functionality and
increased mildness.

PROCETYL AWS
APPLICATIONS/FUNCTION
Soluble Bath Oils and Essences: Perfume Solubilizer

PROCETYL AWS is recommended as a solubilizer for soluble bath oils, bath essences
and other hydroalcoholic systems requiring the incorporation of fragrances or similar
ingredients that would otherwise be insoluble in aqueous alcohol. Since fragrances are
notorious for their incompatibility with many of the ingredient components of emulsions,
their inclusion is often a cause of emulsion instability. This problem in itself is one reason
PROCETYL AWS is so highly recommended as a solubilizer, since its presence can be
helpful in preventing any potential instability. Bath essences are preparations consisting
of perfume, herbal extracts, etc. and are solubilized into bath water by the aid of a
surfactant acting as a solubilizing agent. The solubilizer is typically incorporated at levels
several times higher than the concentration of the material to be solubilized.
Shampoos: Superfatting Agent/Conditioner/Solubilizer

As an emollient, PROCETYL AWS has superfatting properties, which can help reduce
the harsh, degreasing effects most anionic surfactants exhibit in shampoos. PROCETYL
AWS is also useful as a conditioner in hair care products where it imparts anti-static,
emollient and humectant properties to help give hair more sheen, softness and
manageability. Because of its powerful solubilizing action, PROCETYL AWS is able to
assist in solubilizing fragrances into the surfactant solution, doing so without adversely
affecting foam generation or the stability of the emulsion.
Hair Sprays: Plasticizer

The non-sticky, transparent films PROCETYL AWS produces help plasticize the resin
and provide conditioning in hair sprays. Compatible with most of the resins used,
PROCETYL AWS is particularly effective in those systems based on butyl esters of
polymethyl vinyl ether/malic acid. Its ability to migrate to the surface of the film enables
PROCETYL AWS to add lubricity and give hair better combability.
Antiperspirants: Anti-staining Agent/Dispersing Agent/Emollient

With an HLB of 16 and surface tension measuring 28 dynes/cm (as is) and 32.5
dynes/cm (as a 1% solution), PROCETYL AWS possesses surface activity in the range
considered to be effective for good suspension and wetting of the actives used in
antiperspirant sticks. Because of its ability to improve the water dispersability of these
actives, PROCETYL AWS lessens the tendency of the stick to cause fabric staining. For
this reason, PROCETYL AWS is particularly desirable in aluminum salt systems*, since
these formulations are prone to fabric staining. It is extremely effective as a dispersing
agent for the finely divided powders used in these dry systems, since it is able to provide
better re-dispersion of the active.
* Although used in sticks and roll-ons, zirconium salts like the aluminum/zirconium
tetrachlorhydrex-gly-complexes (AZG and ZAG) cannot be used in aerosols, since their
use in these products is prohibited in the United States. Aluminum chlorhydrate salts
(ACH) are the only active ingredient approved for aerosols.

After Shave Lotions/Skin Toners: Emollient/Auxiliary Emulsifier

The use of PROCETYL AWS in after shave preparations, even at low concentration, is
sufficient to improve the emolliency of these systems. In emulsified systems it can be
used as a primary or secondary emulsifier.
Soap Bars: Anti-cracking Agent/Processing Aid

PROCETYL AWS can be used in the production of bar soaps where it helps to prevent or
reduce the incidence of wet cracking of the bar. In the case of primary manufacturing,
PROCETYL AWS should be added at the wet soap stage prior to drying. On the other
hand, when remilling, PROCETYL AWS should be added prior to milling and
incorporated with the perfume and other ingredients at the mixer stage. Recommended
use level is 2%. While its primary function is as an anti-cracking agent for these soap bar
systems, PROCETYL AWS also acts as a processing aid since its inclusion facilitates the
interaction of other additives.
Other Applications:
PROCETYL AWS can be used as a wetting and dispersing agent for the pigments in
aqueous make-up preparations. In curl activators it acts as a gloss enhancer and
perfume solubilizer.

DISPERSIBLE BATH OIL BP-6

This dispersible bath oil is an aqueous/alcohol based system that is formulated without
mineral oil. PROCETYL 10 and PROCETYL AWS provide a rich emolliency, thereby
eliminating the need for heavy oils. PROCETYL 10 acts as a spreading agent and
coupler for the fragrance. PROCETYL AWS is an emollient and humectant and is used
to help solubilize the fragrance. The addition of the alcohol assists in perfume lift.

ANTIPERSPIRANT STICK AA-14

This antiperspirant formula uses CRODACOL C-95 to minimize the tackiness that could
otherwise develop in the stick due to high levels of the active, aluminum chlorohydrate.
PROCETYL AWS, a fragrance solubilizer, emollient and humectant, is particularly
recommended in antiperspirant sticks to reduce staining.
