INCI:Lactobacillus Ferment Use Levels: 0.50 - 1.00% Solubility: Water Soluble Appearance: Free Flowing Powder
Introducing Leucidal® SF Max Powder - Your Natural
In response to the evolving consumer preferences in
the personal care industry, we bring you Leucidal® SF Max Powder, the perfect
answer to the growing demand for natural products in formulations. Embodying
the concept of "less is more," this powdered version of Leucidal
Liquid SF Max is a game-changer for
Experience Unmatched Potency: Leucidal® SF Max Powder is not only more
effective but also five times more concentrated than the original. This
powerful boost in potency not only saves valuable formulation time but also
delivers superior efficacy, instilling a higher level of confidence in your
Backed by Cutting-edge Science: Leucidal® SF Max Powder is a
probiotic-based ingredient crafted through the fermentation of Lactobacillusin a precisely defined growth medium. Derived from microorganisms used in
producing revered fermented foods like kimchi and sauerkraut, Lactobacillusbrings its natural prowess to the personal care realm.
Broad Spectrum Protection: Along with acidifying its environment to
restrict the growth of other microorganisms, Lactobacillus goes the
extra mile by producing novel antimicrobial peptides called bacteriocins. These
peptides provide your products with broad spectrum antimicrobial protection.
Maximized Activity: Our manufacturing process involves adding lysozyme
to the ferment filtrate, ensuring a controlled cell lysis that maximizes the
release of antimicrobial peptides, unleashing their full potential.
A 24-hour skin moisturization study was performed involving 20 M/F participants
between the ages of 23-45. Using an untreated control, generic cream base, and
an experimental with the same cream base containing 0.5% and 1.0% Leucidal® SF
Max Powder, moisturization readings were taken and compared. Results from this
study are shown below in Figure 1. A Dermalab Corneometer was used to measure
moisture levels, in μSiemens (μS), as the presence of moisture in the skin
improves conductance. Therefore, the higher the conductance measurements, the
higher the moisture levels.
As demonstrated by the results of this
study, Leucidal® SF Max Powder showed high moisturizing capabilities at both
concentrations of 0.5% and 1.0%. Please note, each value is an average of three
consecutive readings per test site. Based on these results, adding this
innovative product provides the formulator the opportunity to capitalize on
both the natural antimicrobial properties of Leucidal® SF Max Powder, as well
as its ability to provide potent moisturizing benefits to the cosmetic
Leucidal® SF Max Powder can more effectively inhibit the growth
of a variety of bacteria and fungi than its liquid version, Leucidal® SF Max.
The powder version is about five times more concentrated. Therefore, better
results are acheived while also using less product.
The Minimum Inhibitory Concentration (MIC)
test shows comparative results between the two ingredients and shows that both
materials provide broad-spectrum antimicrobial protection. The positive MIC screening
results warranted further testing to confirm its ability to provide product
Double Challenge Tests were completed
using 1.0% Leucidal® SF Max Powder in the water phase of a generic base
lotion formula. Samples were inoculated with E. coli, P. aeruginosa, S.
aureus, C. albicans, and A. brasiliensis.
A Time Kill Test was performed to
determine the change in population of aerobic microorganisms within a specified
sampling time when tested against 1.0% Leucidal® SF Max Powder solution.
The activity of the test material inoculated was evaluated at determined time
intervals of 30 seconds, 1, 5, 10 and 30 minutes after the inoculation to
determine quantitatively the number of viable microorganisms remaining after
the incubation time. As shown in Figure 4, the gram-positive and gram-negative
bacteria as well as the yeast and mold were reduced by 99.9% within 30 seconds
after the inoculation.
Leucidal® SF Max Powder can be used in a wide range of cosmetic
products; however, to ensure optimum results we recommend using the following
guidelines. Incorporate the product into formulations at a pH between 3 and 7
during the aqueous phase of the process at temperatures lower than 70°C.
Storage: Store in a dry place at temperatures not
exceeding 32°C. Based on stability studies, the optimum storage temperature for
maximization of shelf life is 23 - 25°C. However, it may be stored at temperatures
between 16 and 32°C if such specific temperature control is not available. Do
not freeze. Please refer to stability data for effects heat or cold may have on the
specifications of the product.
Shelf life: 12 months, properly stored, in sealed
This product should be added to a
formulation at the recommended usage rate.
