SOYENNA Powder 500 g

Soy peptide powder built for pigment-correcting formulations

SOYENNA powder is a concentrated soy peptide ingredient widely used by formulators to create products aimed at correcting uneven skin tone and reducing visible pigment marks. It belongs to the group of actives gathered under Depigmentation and Skin Lightening, a category most in demand among professional skincare labs, contract manufacturers and brands developing serums and creams for post-acne marks, sun spots and age-related hyperpigmentation. The bulk of global demand for peptide-based lightening actives comes from the professional and semi-industrial cosmetic manufacturing sector rather than home crafting.

The working mechanism of soy peptides is linked to reducing the signaling activity responsible for transferring pigment from melanocytes into upper epidermal cells. This results in a more even melanin distribution and a gradual fading of visible dark spots over time. In multi-active formulas, SOYENNA is frequently paired with complementary ingredients such as Aminopropyl Ascorbyl Phosphate, a stable vitamin C derivative that reinforces antioxidant protection and supports collagen synthesis alongside the brightening effect. Another common pairing is Stearyl Glycyrrhetinate, which helps calm redness that often accompanies post-inflammatory pigmentation.

In restorative formulations, this soy powder is also combined with placental protein, adding a regenerating and firming dimension to serums that target both tone evenness and skin resilience. Such dual-action combinations are popular in anti-aging lines and treatments designed for stubborn post-acne marks.

The 500 gram package size is aimed at small to mid-scale laboratories, studio-level manufacturers and emerging cosmetic brands that need a dependable supply of raw material for recurring batches of creams and serums. This volume supports formula testing before scaling up as well as consistent small-batch production runs where formula uniformity between batches matters.

The recommended usage rate for this soy peptide concentrate in finished formulas ranges from 1 to 3 percent of the total product mass, with the exact concentration determined by the formulator based on the desired effect and the rest of the recipe. The ingredient should be added during the cold phase of production, once the base emulsion or water phase has cooled below 40 degrees Celsius, to avoid degrading the peptide structures under heat. It is advisable to pre-dissolve the powder in a small amount of water or hydrosol before blending it into the main batch.

Store the raw material in a dry place away from direct sunlight, at room temperature, in a tightly sealed container to prevent moisture exposure. Under proper storage conditions the ingredient retains its activity throughout its stated shelf life, supporting consistent performance across production runs.

Brightening night serum concentrate

Distilled water 68 g

Propanediol 6 g

SOYENNA powder 2.5 g

Aminopropyl Ascorbyl Phosphate 0.4 g

Stearyl Glycyrrhetinate 0.15 g

Xanthan gum 0.4 g

Broad spectrum preservative 1 g

Water-soluble emulsifier 2.5 g

Combine distilled water and propanediol in a beaker and warm gently to around 45 degrees Celsius, then sprinkle in the xanthan gum while stirring continuously until fully dispersed with no lumps. Allow the mixture to cool below 35 degrees, then blend in the pre-dissolved SOYENNA powder along with the vitamin C derivative, the licorice derivative and the emulsifier. Add the preservative last, mix until homogeneous, and transfer the finished serum into opaque pump bottles for storage.
