PADMA (phenyl acetaldehyde dimethyl acetal) (10% in DPG) is a pre-diluted aromatic blend offering the soft, honeyed, floral-green character of PADMA in a convenient and easy-to-use solution with DPG (Dipropylene Glycol). PADMA is widely used in perfumery for its ability to soften sharp floral notes, add naturalness to bouquets, and impart a gentle linden blossom or muguet-like nuance.

This 10% dilution allows effortless incorporation into floral bases, air fresheners, body sprays, attars, and more—especially in lily-of-the-valley, jasmine, and spring floral compositions. It blends seamlessly with materials like Hydroxycitronellal, Linalool, and Citronellol.

SCENT DESCRIPTION
PADMA opens with a bright, dewy green freshness that immediately evokes freshly cut hyacinth stems and rain-dampened garden foliage. The core character is a clean floral-green with a watery transparency that reads as light, airy, and faintly waxy. As it develops on skin, a soft rosy-green facet emerges, lending the note a classical floral elegance without heaviness. The overall impression is of a living garden just after morning rain — lifted, transparent, and unmistakably fresh.

IFRA 51st Amendment Status

PADMA (CAS 101-48-4) is not listed as a restricted or prohibited material in the IFRA 51st Amendment as a standalone ingredient. As an acetal precursor, formulators should be aware that hydrolysis can release free phenylacetaldehyde under acidic or alkaline conditions, which carries its own sensitization profile at elevated concentrations.

⚠️ Always verify current IFRA compliance status with your supplier before commercial production.
⚠️ For leave-on products, use conservative rates and conduct stability testing to confirm acetal integrity throughout shelf life.
⚠️ Do not apply neat to skin — always use in a diluted, finished formulation.

Method 1 — Direct Dilution in Perfumer's Alcohol
Dissolve PADMA directly in perfumer's alcohol at 0.1 to 0.5% before incorporating into your fragrance concentrate. Because it is highly potent, pre-diluting to a 10% solution in ethanol first allows for precise measuring and even distribution throughout the formula.

Method 2 — Accord Building in Carrier Oil
For attars or oil-based fragrances, first dilute PADMA in DPG or fractionated coconut oil to a 10% pre-dilution. Then blend with phenylethyl alcohol and linalool to build a hyacinth or fresh green floral accord. This approach gives precise control over the green freshness intensity before introducing heavier base materials.

Method 3 — Functional Fragrance Blending
For detergent or home care fragrances, combine PADMA with citrus top notes, light musks, and ozonic materials to create a clean laundry or surface-care accord. Its sillage in rinse-off applications is exceptional — even at 0.05% it registers clearly as a diffusion booster and freshness contributor.

Best Pairings

Phenylethyl Alcohol → Creates a classic rose-hyacinth accord with dewy floral depth
Hydroxycitronellal → Adds lily-like sweetness and amplifies the fresh living-flower character
Linalool → Softens the green edge and introduces lavender-floral balance
Hedione → Amplifies diffusion and adds transparent jasmine warmth to the blend
Lilial (BMT) → Reinforces fresh-cut floral quality — ideal for muguet and snowdrop accords
Geraniol → Adds a rosy-green dimension for rose-hyacinth and garden compositions
Iso E Super → Grounds the green character and adds an elegant woody dry-down

Avoid

Avoid combining PADMA at elevated concentrations with strongly acidic or alkaline raw materials as this promotes hydrolysis of the acetal bond and degrades scent quality. Do not use neat on skin. Avoid direct addition to high-pH cold-process soap bases without thorough stability testing beforehand.
