Ambrinol S

from €11.90

Synthetic Animalic Ambergris Ingredient for Perfumery

Ambrinol S, manufactured by Symrise, is a synthetic ambergris material supplied as a clear, colorless liquid. It is not a single α-ambrinol molecule: its product data sheet lists two chemical names, 1,2,3,4,4a,5,6,7-octahydro-2,5,5-trimethyl-2-naphthol and 4-(2,6,6-trimethyl-2-cyclohexen-1-yl)butan-2-one, with two CAS numbers. The odor is animalic and ambergris, with musk, earthy and violet facets.

Symrise positions it in musky, amber and leather compositions, where it adds volume and performance to the musky part of a fragrance, a natural aspect to amber ingredients and an animalic-floral facet to leather accords. Its odor and discoloration stability is base-dependent: after three months at 40 °C, Symrise reports results that vary across functional and personal care bases such as fabric softener, detergent, soap and shampoo.

What is Ambrinol S?

Ambrinol S 690993 is a synthetic perfumery material by Symrise (BLH, n.d.). Its product sheet lists two chemical names and two CAS numbers.

Historical Background

The story of ambrinol begins with the study of natural ambergris. One of its main constituents, ambrein, has only a mild scent; its oxidation can produce odorants including ambrinol and ambroxide (American Chemical Society, 2020). (−)-cis-α-Ambrinol is among the compounds found in natural ambergris (López-Martínez et al., 2023).

According to dsm-firmenich, its research into ambergris began in the 1930s and led to the synthesis of Ambrox and Ambrinol in the 1950s (dsm-firmenich, n.d.). Firmenich's historical account lists Grisambrol, a specialty containing both materials, in 1954 (Firmenich, 2016).

In her review, Anonis (1995) reports that Mookherjee and Patel identified α-ambrinol among the volatile constituents of an ambergris tincture in their 1977 work.

Research into α-ambrinol synthesis continues. López-Martínez et al. (2023) described a route starting from α-ionone; their work concerns the molecule, not a disclosed manufacturing route for Ambrinol S.

Olfactory Profile

The following profile is based on Symrise (n.d.).

Main Descriptors: Musk, earthy and violet facets accompany the animalic ambergris character.

Intensity: Symrise reports an air threshold of 0.0063 µg/L.

Tenacity: Approximately one day on a blotter, as read from the manufacturer's chart.

Applications in Fine Fragrance

Symrise (n.d.) describes these uses:

  • Musky compositions — An increase in volume and performance in the musky part of a fragrance.

  • Amber accords — The material can add a natural aspect to amber ingredients.

  • Leather accords — It can bring out an animalic-floral facet.

Performance in Formula

Symrise (n.d.) recommends use from traces up to 1% in perfumery.

Stability: The manufacturer presents odor and discoloration results after three months at 40 °C in several product bases; results vary by base.

Industrial & Technical Uses

Symrise (n.d.) includes the following matrices in its stability assessment:

  • Functional Perfumery — Fabric softener, detergent and cleaner.

  • Personal Care — Soap, deodorant, shampoo, shower gel, hair conditioner and body lotion.

Sustainability Credentials

Symrise reports 39.0% biodegradability and describes the material as partly biodegradable (Symrise, n.d.).
