This was an extremely busy year for the
Seminar Committee under the guidance of
Charmaine du Preez. A record amount of five
Refresher Mornings and a Supplier Day were
hosted. The overall feedback on these events
was positive and we would like to thank our
presenters for sharing their wealth of
knowledge with our members.
Soap Refresher – 14 March
• The Basic Processing of Glycerine Soaps by
Berdine De Jager, Aurora Soap
Manufacturing.
• Trends for Soap Bars 2018 and Beyond
(Mintel Review) by Rene Spada, Evonik South
Africa.
• Emollients used in Soap by Beverley
Gardner, Symrise.
• Soap Bar Technology by Sid Palmer.
• Toilet Soap Technology by Suren Naidoo,
Quality Products.
Sid Palmer discussed the composition of basic
oils, indicating carbon chain distribution and
melting points of saturated and un-saturated
fatty acids required for soap bar making.
Unsaturated fatty acids, the C12, C16 and C18
carbon chains, contribute to shape and lather.
He also explained the chemical structure of a
soap bar, different manufacturing methods and
some pitfalls that can occur, such as cracking,
mush, grit and hardness.

Suren Naidoo from Quality Products discussed
various aspects of soap making and the
history of soaps in medieval times. Soap is
formed with alkaline substances and fats and,
depending on the different carbon chains,
either a soft and hard soap is produced.
Longer chain fatty acid molecules produce a
hard soap, which is difficult to dissolve in water.
Softer soaps that lather easier are produced
using shorter chain fatty acid molecules, like
coconut oil. The chemical process
(saponification) occurs when an alkaline
substance reacts with the fats and oils.
Fragrance Refresher – 13 June
• Perfumery by Marie Aoun, Saint d’Ici.
• Fragrance & Fragrance Application
Innovation by Kelefang Mofokeng, Sensory
FX.
• Fragrance Trends 2018 & 2019 by
Zodwa Ndebele, Orkila.
• Fragrance Translation - from Mind to Market
by Vipul Suri & Ofentse Tsipa, Givaudan.
• Millennials Generation by Tiffany de Astui,
Carst & Walker.
Tiffany De Astui discussed Millennials, which
make up over a quarter of the global
population, Millennials are the most influential
generation today and the most difficult to
define due to their multiple dispositions. The
Millennial generation includes their fragrance
in their personal expression, like variety and do
not really have a “signature” scent anymore.
The concept of a “fragrance wardrobe” has
become very popular with millennials because
they can personalise and match their mood,
their style and their way of life. Their
fragrances are often freedom-loving, elegant,
and playful, giving a fresh, youth and pleasing
sparkling facets.
Suncare Refresher – 8 August
• The Ups and Downs of Sunscreen
Formulation by Robyn Brown, Botanichem.
• Innovation in Suncare Solutions by Caroline
Cochrane, The Care Co.
Suncare Regulatory Overview:
Best practice based on International
Standards.
Local Impending Legislation.
Updates from the recent ISO meeting
held in Poland by Dershana Valla,
CTFA.
• SPF Tests 1010 by Beverley Summers,
Sefako Makgatho Health Sciences University.
• SPF Testing – The Way Forward by Marlize
Lategan, Sefako Makgatho Health Sciences
University.
Refresher positioning: How the organic and
inorganic filters work in a Sunscreen. UV
Filter combinations in a Sunscreen and how
they follow the Market Trends by Andre Burger,
Sun Skin Sunscreens.
Andre Burger from Sun Skin, discussed how
the Sunscreen filters have developed over the
last twenty years to eliminate the short
comings of the older generation filters. A
concern of some of the older Ultra Violet (UV)
filters is their instability when exposed to high
doses of ultra violet light. They become
ineffective.
Companies like DSM and BASF realized the
shortcomings and developed stable and
effective UV-filters that can be used in lower
concentration. Some of these modern filters
have a dual method of operation. They firstly
reflect some of the UV light and then
neutralize the remaining UV light. Another
advantage is that their absorption spectrum is
larger and therefore the synergistic effects with
other filters are good.
The two types of physical (mineral) UV-filters
that are available are Titanium Dioxide and
Zinc Oxide. These filters are crystals that are
finely grinded and used in a sunscreen
formulation and spread in a thin layer on the
skin. They reflect the UV rays, but their
effectiveness is not as good as that of the
organic UV-filters.
