Brightening Emulsion Serum Base

No reviews yet

Brightening Emulsion Serum Base is a milky serum for tone-care fills. It is a fluid emulsion, not the clear vitamin C gel. 50 kg MOQ.

How To Use Bases

These bases are formulated so you can customize them. You may add up to 15% purified water, oils, or other ingredients without disturbing the preservative system.

How to Fill Jars

Work in a clean, sanitary space. Use a manual filling machine, a piping bag, or a large squeeze bottle to fill bottles and jars.

How much Fragrance or Essential Oil to add

Stay within the maximum percentage recommended for that fragrance or essential oil, and do not go over it. Gels often thin out once they are scented. If that happens, a gel thickener can bring the body back.

Formula overview

Brightening & Tone Care

Set this milky serum sample beside the brief before you request documents for a bulk order.

The serum should pour and stay milky. If it sets like a cream, the oil phase is too high.

Reference allocations as INCI component equivalents, w/w: Niacinamide 4%, Ascorbyl Glucoside 2%, Glycerin 4%, Caprylic/Capric Triglyceride 4%. Percentages describe development references, not actual supplier-product dosing, batch assays or approved production BOMs. Supplied-grade composition and signed formulation records determine production dosing and final label INCI.

Ingredient encyclopedia — customization details

Deep-dive notes for the lead actives in this chassis: identity, use levels, regulatory framing, safety language, and stability/packaging guidance for professional development.

1. INCI & CAS

INCI: Niacinamide · CAS: 98-92-0

2. Role in the formula

Kept at 4% so the serum can stay beside the cream without copying its body.

3. Typical use levels (formulation guide)

Reference component allocation: 4% w/w.

Add in the cool-down. Design target pH about 5.5–6.5.

7. Claims language (Do / Don’t)

Supports a tone-care story

1. INCI & CAS

INCI: Ascorbyl Glucoside · CAS: 129499-78-1

2. Role in the formula

Ascorbyl glucoside is not L-ascorbic acid. Color is checked on the stability sample.

3. Typical use levels (formulation guide)

Reference component allocation: 2% w/w.

Dissolve in the cool-down. Do not boil.

7. Claims language (Do / Don’t)

Supports a vitamin C derivative story

1. INCI & CAS

INCI: Caprylic/Capric Triglyceride · CAS: 73398-61-5

2. Role in the formula

Four percent ester is enough to look milky and too low to set as a cream.

3. Typical use levels (formulation guide)

Reference component allocation: 4% w/w.

Emulsify with the oil phase. Keep the finished serum pourable.

7. Claims language (Do / Don’t)

Supports a milky serum look

Do not claim whitening, acne treatment, antiperspirant, sunscreen, or hair growth from this guide

Stability & QA protocol for the finished chassis

These checks are the professional release path for Brightening Emulsion Serum Base. They describe what we verify before commercial fill — they are not published batch results for this bulk base.

Accelerated & real-time stabilityTrack appearance, odour, pH and viscosity at agreed temperatures for the target fill and pack.
Freeze–thaw / thermal cyclingConfirm no phase split, precipitation or irreversible darkening after cycling.
Preservation challengeValidate the preservative system against the selected formula and packaging before scale-up.
Light / packaging compatibilityPrefer opaque or UV-protective packs where actives need light protection; check leachables and pump/dropper fit.
pH window controlHold the finished chassis near pH 5.0–6.0 unless the approved brief states otherwise.
Document gateRelease only after TDS/SDS, specification and batch COA identity are approved for the confirmed formula.
