Any of the texture analyser range can be used for the product tests listed below.

A selection of special attachments and typical measurements which are commonly used in this application area are shown above. However, this does not show the complete range of attachments available for the testing of cosmetic and skincare products. Test procedures include: compression, puncture/penetration, tension, fracture/bending, extrusion, cutting/shearing.

Cosmetics and Skincare Testing

 

 

 lipstick-break-strength  cylinder-probes-hardness  cylinder-probe-shadow
Lipstick Break Strength
This cantilever test provides both
imitative and empirical results in
one test. Action is provided by a
hemispherical edged blade which
simulates the bending action
caused during application.
Cylinder/Needle Probes for
Hardness measurement
Besides determining lipstick
Hardness , this test may also
indicate the presence of unwanted
trapped air bubbles, or a "grainy"
texture as a result of either
incomplete colorant dispersion
or the working and chilling
processes during manufacture.
Small Diameter 
Cylinder Probes
The test shown above can indicate
the presence of air pockets beneath
the sample surface, which may be
undesirable, and the optimal
pressing time and weight of e.g.
eyeshadow and compressed face
powders.
 eye-pencil-rig  cylinder-probes-soap  forward-backward-extrusion-rigs
Eye Pencil Rig
The test shown above provides the
means to quantitatively measure
the hardness of pencil tips such as
those for eye- or liplining products.
Results will assess such process
variables as the modification of wax content or product quality
as a result of extreme
temperature conditions.
Cone/cylinder/needle probe
A standard test such as ASTM Dl
321 -95 using a needle probe or
ASTM D937-92 using a conical probe
provides a means of measuring the
firmness or consistency of waxes
and is also suitable to assess the
hardness of soap and similar
products (as shown).
Back/Forward Extrusion Rig
Consistency of moisturising cream
can be assessed by either a forward
extrusion test (simulating the force
required to extrude a sample by the
consumer) or a backward extrusion
test which will give an indication of
product physical failure and viscosity.
 film-support-rig  tube-sachet-extrusion-rig  actuation-force-testing
Film Support Rig
This rig allows testing of thin, film-
like products to measure the burst
strength, resilience and relaxation
properties.
Tube/Sachet Extrusion Rig
allows manufacturers to measure
the ease of removal and application
of products such as sauces, pastes,
creams and gels.
Actuation Force Testing
allows measurement of the force
required to release hair fixatives
from aerosols, soap/cream from
dispensers.
 hair-combing-rig
Hair Combing Rig
(Registered Design)
Enables the comb to be disengaged
at the end of each combing stroke
for realistic assessment of hair combability.
