SQT® Spongilla Spicule 2.0 (II)
The Purity of Crystal Needle
How does SQT® improve the purity of Spicules？
· Why does the purity is important？
· What are the harm of impurities？
· How to determine the purity of Spicules？
· What had we done to improve the purity？
Why is the high purity so important?
The essential condition
for making top-level
cosmetics
Greatly reduce the cost
of impurities and
processing difficulty
Comprehensive
protection for
consumer’s safety
Increased the selectivity
for adding into different
cosmetic categories
Harms of Impurity to Skin
Irritant contact dermatitis (ICD) Commonest
Allergic contact dermatitis (ACD)
Photosensitive dermatitis induced (PDI)
Cosmetic acne
Cosmetic skin pigment abnormality
The Criteria of the Purity of Spicules
The purity of Spongilla Spicules determined by two dimensions: The Content and the Color
The content of Bio-silicon determined by Gelatin Coagulation Gravimetric Method
The content of Protein determined by Kjeldahl Method
*The international standards of content were adopted by SGS // GB/T5009.3-2016
The Chrominance of Spicules is the comparison test which is
according to Natural Colour System® (NCS) standard
Formula of Gelatin Coagulation
Gravimetric Method:
Purity of Biological silicon calculate on W1 mass fraction of SiO2,
numerical value in %, calculation based on formula A.1
W1=(M1-M2)/M0×100% ..... A.1
* M1 — sample residue and Mass of nickel crucible（g）.
M2 — Mass of nickel crucible（g）.
M0 — mass of sample（g）
Use the arithmetic mean value Of Parallel result, the absolute difference of
two parallel results should not matter than 0.2%.
Procedure of Gravimetric Method
1. Grind & Screen
2. Sample
3. Weigh
4. Gelatinization
& cauterize
5. Cool & Re-weigh
6. Calculate
Result of spongilla spicules Content Test
Use the arithmetic mean value Of Parallel result
Chrominance Comparison Test
NCS - Natural Colour System®
is a international scientifically based
colour system that allows for accurate
cross-industrial colour communication
for designers and manufacturers,
and customers. The system allows
you to describe colour on all imaginable
surface. This has made the colour
system a global standard for definition,
quality assurance and communication
of colour.
4 Tops of SQT for Improving the Purity
SQT - All raw materials of freshwater sponges came from
Hunan Dongjiang Lake which is the I-Grade of National
Drinking Water from 2011-2019 (GB3838-2020)
SQT - Deeply cooperated with National Key Labs- Hunan M&M LAB.
Top scientific R&D and QC team, sophisticated equipment are the
necessary for highest class purity products, and all the
production detection reagent are certificated by CNAS & SIGAMA
SQT - Producing process, QC and packaging are conducted SQT
Quality Control and Appraisal System (SQCAS) which is according
to ISO-9001 standards, that was approved by US-FDA and KOSHER
