Use of Micro Beads in Cosmetics
1. Optical Effects
Soft Focus effect, optical blurring
Matte look
Optical blurring effect is
widely applied to not only
make ups but also skin care
Can generate soft focus without increasing
opacity or accentuating fine lines and wrinkles:
creates a more natural looking appearance
2. Sensorial Modification
Micro Beads can alter the Reduce too much tackiness

Micro Beads can produce special textile effect
like 鈥渃ream-to-powder鈥?
3. Absorption, Release, Delivery
Porous Micro Beads can be Sebum, oil absorption

surface.
When applied to the skin, the
volatile material evaporates from
the microsphere, leaving it empty
and ready to absorb. If perspiration
is absorbed, it is released as vapor,
thus reducing wetness. If sebum is
absorbed, it is isolated from the skin
preventing oily feel and shine.

Fresnel Loss
When light rays cross the boundary from one medium t another, there is a loss due to reflection at the boundary, this
is called Fresnel loss and is calculated with the following expression
Rm: Refractive Index of Media
Fresnel Loss = 100*(Rm-Rp)2/(Rm+Rp)2 Rp: Refractive Index of Powder

Background
鈥? Make-ups always need coverage.
鈥? In order to provide coverage, you need white pigment.
鈥? Among available white pigments, TiO2 is the most
widely used due to its unique high refractive index
which provides outstanding coverage.
鈥? Unfortunately,. TiO2
TiO2 also imparts a very
harsh feel which is detrimental
to the sensorial quality of
make-ups
Silica Bead
+
Spherical TiO2 possible?
鈥? There have been many approaches towards improving
the feel of TiO2 including the development of spherical
TiO2.
鈥? In reality, however, spherical TiO2 was not truly
spherical but semi-spherically aggregated TiO2
particles, fragile and prone to breakage under pressure.
鈥? Nowadays, TiO2 is usually pre-mixed with flakes to
improve its harsh feel.
鈥? ISN鈥橳 THERE A BETTER SOLUTION?

200nm TiO2 encapsulated Silica Bead
鈥? SUNJIN Chemical developed a new product, spherical
TiO2 encapsulated silica bead in 2006.
鈥? Silica bead is 2~10um with 200nm TiO2 35% inside.
鈥? Silica gives excellent sensorial feeling while TiO2
provides good coverage.

Regulation & Trend
EU Recommendation of 22 September 2006 on the efficacy of sunscreen products
Sun Protection Factor minimum 6.
UVB Protection Only 8 defined SPF values allowed
Level of UVA protection (measured by in vivo or in vitro
UVA Protection methods) at least 1/3 of labelled SPF. (UVA label can be
used to highlight achievement of protection level)
Additional criteria, minimum of 370nm to ensure broad
Critical Wavelength band protection
All products need to comply by 2009, at which point it is
expected to be treated as a law.
Products that do not comply with these requirements will
not be regarded as 鈥楽unscreen Products鈥?
Sun care market trends
High performance sun care such as SPF50+, PA+++ is big marketing trend,
especially in Asian market Leading sun care producers add more UVA filter significantly
to achieve a good UVB/UVA balance
More and more products claim a measurable UVA protection factor
In order to achieve a good UVA balacne in high SPF formulations, the use of a highly efficient
UVA filter such as BMDBM is essential
High SPF formulations of today contain most often TiO2 to achieve significant UV protection
Residual whitening is also a common challenge with many of today鈥檚 TiO2 qualities available
on the market
Many grades of TiO2 contain alumina as coating and are therefore not compatible with

small size," Concerned about such ambiguity, the environmental group Friends of the Earth in
Washington, D.C., has called for a ban on use of nanoparticles in sunscreen pending further
study, citing results of a survey it conducted of sunscreen manufacturers released this week.
"That would be a mistake because you are then coating your skin with a nice layer of free
radical generating stuff.鈥?
Further, it is not clear how nanosize titanium dioxide or zinc oxide could pass from the skin to
organs such as the liver or brain where they might do damage. Of 15 scientific studies
conducted by government, industry and independent researchers over the past decade, only
one found that nanoparticles were absorbed by the skin of rabbits; none detected human skin
penetration, even with an electron microscope.
ECOCERT, JANUARY 2003
Therefore, the Environmental Working Group (EWG) recommends using sunscreens that
contain zinc oxide or titanium dioxide, nanosize or not. EWG also prefers these formulations

because studies show that sunscreens containing alternative organic chemicals such as
substances submitted to specific oxybenzone and octinoxate seep through the skin into the body where they can sometimes

Really?
1. SPF is the half of TiO2
Recently some zinc oxide suppliers significantly improved SPF of nano zinc oxide.
SUNZNO-NAS generally has unit SPF efficiency of 1.4 SPF unit/% in W/O
formulation.
Moreover, ZnO has great synergy with OMC. Thus the SPF of 3% ZnO and 5% OMC
would be comparable to the SPF of 3% TiO2 and 5% OMC. Although ZnO would
have lower SPF than TiO2 by themselves, ZnO shows greater SPF boost when used
together with OMC compared to TiO2 with OMC.

However, if zinc oxide is well
At pH values < 6, the solubility of zinc oxide increase and migration from the oil

phase to water phase observed
no problem.
For this reason, ZnO is usually incorporated into the oil phase of the formulation.
Moreover these problems can be minimized or eliminated by various means.
Use of an optimized predispersion maintains the ZnO in a finely dispersed form
in the oil phase. In W/O emulsions, such dispersion techniques are sufficient to
eliminate migration and efficacy of ZnO. ZnO can also be coated with
hydrophobic materials in order to reduce migration
3. Price twice expensive than TiO2
Again as SUNJIN chemical applies 1 step coating process for
surface treated Zinc Oxide, zinc oxides from SUNJIN are very
price competitive. SUNJIN tries to match the price level of Zinc
Oxide comparable to the price of micro-fine TiO2

Zinc oxide is the closest thing to a total "broad-spectrum" sunblock
on the market today. It uniformly covers from 290 to 380 nm, thus protecting
against UVB and most of the UVA spectrum. No other sunscreen ingredient
provides broader protection. And unlike many chemical sunscreen agents, zinc
oxide is never irritating. In fact, it is recognized by the Food and Drug
Administration as a Category I skin protectant, meaning that it is safe for
compromised or environmentally challenged skin. Zinc oxide has over a 300-year
history of safety, with no known adverse reactions (which is why it is often used to
treat babies). Now, in its micro-fine form, it is ideal for use in sunscreens and daily
moisturizers.
