Brazil
The cosmetics and toiletries sector
has shown an average growth of
10% annually over the past 18
years, moving from R$ 4.9 billion in
1996 to R$ 38 billion in 2013.
Brazil is a 41.7 billion dollars/year market
for cosmetics and personal care products,
which places the country as the 3rd
largest market in the world.

Factors contributing to the impressive
growth of the sector:
 Increase of the population's income, with the new members of the
middle class beginning to consume products with higher added value
 Increase of the participation of women, who for 20 years represented
20% of income in the country and who now represent nearly half
 Increased use of new technologies and industrial productivity
 Intense and frequent launches of new products
 Increase in life expectancy, with increased demand for anti-aging
products

$155.8 million in
2012.[http://www.shb.com/newsevents/2011/Nan
oCosmeticsBeyondSkinDeep.pdf]
Widespread use of nanoscale
materials in cosmetics is due to
the fact that these nanoparticles
obtain newer properties which
differ from the large-scale
particles

The rigidity of both the polymer wall and lipid core is quantitatively higher for LNCs.
In conclusion, LNCs presented distinct elastic properties compared to the conventional polymeric NCs.

• 70% of entrepreneurs said that biodiversity is
important to their business, especially Bolivians and
Brazilians with 85% and 80%, respectively.
A survey
• And over 94% of respondents in Brazil, Colombia and
Peru said the interest in natural ingredients will
increase over the next 10 years.
• Most companies in the studied countries (80%) bet
on natural ingredients as a source of technological
innovation in their products.
In Brazil, biodiversity is on the radar,
especially in the cosmetics industry.

Biodiversidade como “o cofre de um patrimônio
químico
inexplorado de remédios, alimentos, fertilizantes, pesticidas,
cosméticos, solventes, fermentos, têxteis, plásticos, celulose, óleos e
energia, além de moléculas, enzimas e genes em número quase infinito”.
Arnt (2001)
Biodiversidade pode ser entendida como uma
preciosa “biblioteca

Apenas em torno de 10% da biodiversidade
mundial foi estudada.

ANTIOXIDANTES TÓPICOS
• Os antioxidantes tópicos devem ser
absorvidos pela pele e liberados para o
tecido-alvo na forma ativa.
• Entretanto, muitos produtos se oxidam e
se tornam inativos antes mesmo de
alcançarem o alvo.
• A absorção é um processo muito
importante e depende de vários outros
fatores, como, por exemplo, a forma
molecular do composto ativo, suas
propriedades físico- químicas, se sua
solubilidade em água ou em lipídeos, seu
pH e o veículo que contém o produto.
