Hello,
This is Sunjin Beauty Science.
Are you looking for highly oil-absorbing silica beads for baby care and hair care products such as dry
shampoo, offering a fresh, powdery feel and excellent oil absorption?
High oil absorption alone is not enough when selecting silica beads.
Especially for products where the
powder is directly applied to a baby’s skin or hair, it is important to consider not only particle size and
particle size distribution, but also the content of fine particles.
SUNSIL-MS170H is a silica bead engineered with Sunjin’s advanced particle control technology to
achieve a
uniform particle size distribution, with D10 ≥ 10 μm and an average particle size of 15 μm. It delivers
excellent oil absorption and a smooth, pleasant feel, along with high transparency.
Benefit 1. Fluidity & Silky Texture
With a large average particle size of 15 μm and a uniform particle size distribution, SUNSIL-MS170H minimizes
particle agglomeration and interlocking, delivering excellent Fluidity. On the skin, the smooth movement of
the particles and low friction provide a soft, silky Texture.
Benefit 2. Ultimate Transparency
Its uniform particle design minimizes unnecessary light scattering, delivering enhanced transparency.
Benefit 3. D10 > 10 μm Minimized Fine Particle Content
With its uniform particle design achieving D10 ≥ 10 μm, SUNSIL-MS170H minimizes fine particle content and
provides a versatile silica solution suitable for a wide range of formulations, from baby care to hair
care.
[Technical Q&A] SUNSIL-MS170H: Researchers Ask, Sunjin Answers
We’ve compiled practical tips based on the questions researchers most frequently ask when designing
formulations.
Q1. How is it different from the silica I have been using, and what should I consider when selecting a
silica?
A: The properties of silica—such as dispersion, sensory feel, and oil control in formulations—vary depending
on particle size and particle size distribution, specific surface area, and oil absorption
capacity.
Choosing the right physical properties based on the target formulation and desired functionality
is key. Please refer to the table below to select the most suitable silica for your application.

Q2. How does it differ from LUX150H, which offers excellent flowability and transparency?
A: LUX150H features a smooth, clean particle surface, delivering excellent transparency and
flowability
along with a soft, pleasant sensory feel. In contrast, MS170H is designed based on Uniform
Particle
Engineering, with a controlled and uniform particle size to achieve transparency, flowability,
and sensory
properties as close as possible to those of LUX150H. As a result, MS170H achieves a level of
transparency
and flowability comparable to LUX150H. However, LUX150H provides a superior sensory feel due to
its smooth
particle surface.
Tip.
LUX150H → Smooth Surface · Superior Sensory
MS170H → Uniform Particle · Consistent Performance
Q3. Which hair care formulations is it suitable for?
A: It is particularly suitable for powder-type hair care products, such as dry shampoo.
Its high
oil
absorption capacity effectively absorbs sebum and excess oil from the scalp and hair, while its
relatively
large particle size and uniform particle size distribution provide even application and excellent
flowability. In particular, its D10 ≥ 10 μm particle design minimizes fine particle content, making
it a
suitable silica solution for powder formulations applied directly to the scalp.
Q4. Are there any special considerations for formulation and manufacturing processes?
A: SUNSIL-MS170H can generally be incorporated into formulation and manufacturing processes in a similar
manner to conventional silica, without requiring significant process changes.
However, the sensory feel and dispersion of the final formulation may vary depending on the silica usage
level, composition with other powders, and mixing conditions. Therefore, we recommend evaluating the
appropriate usage level and mixing conditions based on the existing formulation.
