Murumuru butter
Description
Murumuru Butter (Astrocaryum murumuru) is a vegetable butter sourced directly from the Amazon region, with remarkable qualities confirmed by both popular tradition and modern cosmetic use: an intensely nourishing and emollient, highly protective and regenerative agent for both hair and skin, thanks to its notable concentration of lauric acid, myristic acid, and provitamin A. Due to its significant affinity for proteins in the hair structure, murumuru butter acts as an active ingredient for repairing and disciplining damaged, curly, dry hair, or hair with hard-to-control volume.
Although it has a solid consistency and a hard structure at room temperature, murumuru butter melts easily upon contact with the skin, penetrating rapidly and deeply without leaving a greasy sensation or a sticky film, offering instead a silky and smooth touch.
The gentle refining process applied to this butter aims to reduce its strong native odor and dark color, providing a neutral and stable base that is ideal for cosmetic formulations. Its most valuable peculiarity is its remarkable affinity with the hair fiber: lauric acid, with its low molecular weight, has the ability to penetrate the hair cuticle, strengthening it from within, a mechanism similar to coconut oil, but in a richer and more protective form.

Usage & Synergies
For skin care, Murumuru butter is suitable for all skin types, especially for dry, cracked, irritated, or damaged skin. It is useful in formulas for dry or chapped lips, eczema, psoriasis, and for areas with rough skin (hands, elbows, knees, heels). For application on its own, it is recommended to pre-melt it in the palms.
For hair care, it is recommended for dry, damaged, unruly hair, due to its remarkable affinity with the strand's proteins. It smooths frizzy hair and helps define curls, protecting the hair against the frizz effect caused by humidity.
Practical recommendations
- Face and body creams: Added to the oil phase of emulsions to impart creaminess to the preparation, while ensuring easy absorption into the skin.
- Hair treatment: Melt the butter in the palms or in a water bath. Apply to the hair as a mask. Leave on for 15-30 minutes, then shampoo and rinse.
- Ends treatment: Melt a pea-sized amount between the palms and apply to the ends and lengths of dry hair, avoiding the roots.
- Lip balms and lipsticks: Used to provide consistency and nourishing properties to lip care products without altering their aroma.
- Body butters and massage bars: Combined with other vegetable oils and optionally wax to create solid massage products that melt gently on the skin surface.
- Hand or foot cream: Incorporate as an ingredient in creams destined for areas with rough skin.
Synergies in skin and hair care
For a repairing cream for cracked skin, the synergy with Centella Asiatica Oil and Bisabolol completes regeneration and soothing. For eczema or damaged skin, the association with Organic Hemp Seed Oil and Ceramides supports skin barrier repair. As an ingredient in lip balms, it combines well with Cocoa Butter and Ricin Oil. For facial creams, it pairs well with Olive Squalane or Jojoba Oil, preserving a silky finish on the skin.
For a strengthening hair mask, it combines efficiently with Organic Ricin Oil and Burdock Oil. As a treatment for split ends, the synergy with Organic Argan Oil and Phyto-Silicone brings shine and repair without weight. For curly, unruly, or difficult-to-comb hair, the association with Olive-Silicone completes the disciplining effect. For the care and definition of curly or dry hair, it pairs ideally with Argan Oil, Broccoli Seed Oil, or Kokum Butter, creating intensely nourishing hair treatments.
Frequently Asked Questions (FAQ)
Why is it so good for hair?
Lauric acid, the main component, has a low molecular weight, which allows it to penetrate the hair cuticle and fortify the hair fiber from within — a mechanism similar to that of coconut oil, but with a richer, more protective texture.
How does it melt more easily?
Being solid and hard, it is recommended to pre-melt it in the palms by rubbing them together, or in a warm water bath, for an easier and more uniform application.
Is murumuru butter suitable for combination or oily skin?
Although it absorbs quickly and has a pleasant touch, the lauric acid in its composition can have a moderate comedogenic potential for individuals with extremely oily or actively acne-prone skin.
