There are many personal care products which rely upon a good peeling function as their primary physical characteristic.
Medical
bandages, sanitary towels, and nappies are just a few examples of
products that at some point will require to be peeled from skin or
another surface and therefore this adhesive strength will need to be
measured in order to be monitored and/or controlled. Waxing strips are
used as a method of hair removal at home and are typically treated with
wax to remove hair.
The benefit of waxing strips are that they do not
require a heat source in order to grip the hair. Whether applying cloth
strips to heated wax on unwanted hair in a salon or whether using
formulated strips for home-use the success of this treatment is based on
the adhesive interaction that occurs with the hair in order to remove
it when the strips are peeled off.
GELS Hydrogels are becoming a major influence in personal care products today.
There
is a need for hydrophilic, skin adhesive, biocompatible hydrogels that
can be used in a variety of applications such as shampoo, hair setting
gels, face masks, skin fresheners and scented gels (air fresheners).
Currently there are numerous hydrogels on the market, ranging from
viscous solutions to elastic solids. The reason for this recent interest
is that hydrogels can act as moisturising agents and they can deliver
numerous therapeutic ingredients in a controlled manner.
Rheological
properties of semisolids are highly important physical parameters in
both technical (manufacturing, filling, storage) and aesthetic terms.
The
evaluation of semisolid emulsion structure and consistency is therefore
essential in order to determine, adjust, and possibly predict the
corresponding product performance. The emulsifier concentration in the
formulation of the cream and the manufacturing temperature are just two
variables that can effect the flow and viscoelastic properties as well
as the resistance to deformation.
WAX/PETROLATUM Waxes
are an important component of many personal care products such as skin
care, baby products, suntan and sunscreen and lubricating agents.
The
measurement of hardness (or firmness) of these waxes has long been an
important assessment to ascertain their contribution to final product
texture. The hardness of waxes (which is affected by their melting
point) may have a significant effect upon other physical properties and a
measurement of hardness is used to determine whether a wax is suitable
for use in products to provide rigidity, good moulding properties, or is
capable of producing soft emollient films with good lustre.
SOAP & DEODORANT Soap must have the required degree of plasticity within an operating temperature of 30-40°C.
It
is particularly important to achieve the correct plasticity at the
final pressing stage, since the compressed bar must be subject to a
minimum of internal pressure to avoid serious cracking when the bar is
used. To achieve the required degree of plasticity, certain factors must
be controlled. For the dried soap base, these are: water content after
drying; glycerol and electrolyte content; and the nature and quantity of
any additives used in the liquid soap pre-drying.
Before
paint was ever splashed onto canvas or cave walls, it was daubed on
faces and bodies, not only for symbolic purposes but for decoration too.
Today, a plethora of beauty products are seen lined up in the display windows and shelves of shops and stores everywhere.
The
cosmetics and personal care market is extremely crowded, making it an
extremely competitive arena. In this industry, the combination of good
marketing and product quality must be compelling to gain shelf space,
consumer attention and repeat purchase.
Already in the crosshairs of health-conscious consumers, these days sugar is frequently demonised in the media.
Legislation
across the globe is mandating the reduction of sugar in a variety of
products, as well as demanding clearer labelling in an effort to educate
and discourage consumers. Where soft drinks began, the rest of the food
industry is expected to follow. As a result, manufacturers’ need to
reformulate with lower sugar content is higher than ever.
However,
beyond adding a sweeter taste, the reduction or removal of sugar also
impacts the texture of foods which must be addressed. Jam, for example,
relies on sugar for firmness. Whether being spread on toast or added to
cakes, the firmness of jam is crucial to consumer enjoyment and has a
direct impact on its perceived quality.
With
global obesity levels at an all-time high, and an improved
understanding of the impact of fat on the function of many major organs,
low-fat diets are a common approach used by many consumers hoping to
improve their health.
This trend has had huge implications
for the dairy sector, where, to meet this demand, thousands of product
lines are being reformulated, and many more are being launched from
scratch. From dairy drinks and yoghurts to cheeses and dairy desserts,
the low-fat trend is visible everywhere.
