Summary
A novel biopolymer from tara and red algae forms protective films on hair, enhancing shine and smoothness. This ingredient improves hair care product efficacy by reducing environmental damage and improving sensory properties.
Area of Science:
- Cosmetic Science
- Materials Science
- Biochemistry
Background:
- Environmental aggressors negatively impact hair health.
- Biopolymers offer potential solutions for hair protection due to film-forming properties.
Purpose of the Study:
- Develop hair care formulations using a tara and red algae biopolymer.
- Evaluate the rheological, texture, and film-forming properties of these formulations for hair protection.
Main Methods:
- Shampoo, conditioner, and leave-in formulations were created.
- Rheological and texture analyses were conducted over 28 days.
- Hair efficacy was assessed via combability, smoothness, mechanical strength, diameter, and visual appearance.
Main Results:
- Biopolymer formulations significantly reduced hysteresis area, indicating film formation.
- Texture parameters improved, suggesting enhanced sensory properties.
- Hydrogen bonding between the biopolymer and keratin reduced tensile strength and increased hair diameter, improving shine and smoothness.
Conclusions:
- The tara and red algae biopolymer effectively forms films on hair, offering protection against environmental damage.
- This biopolymer shows significant potential for use in advanced hair care products.
- The study demonstrates improved hair aesthetics and mechanical properties through biopolymer application.

892
Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...

01:28Overview of Algae
827
The kingdom Archaeplastida encompasses red and green algae, along with land plants. Unlike other protists with chloroplasts that arose through secondary endosymbiosis, only red and green algae originated from primary endosymbiotic events. This diverse group of eukaryotic organisms contains chlorophyll and performs oxygenic photosynthesis.Algae exist in various forms, from large brown kelp in coastal waters to green scum in puddles and stains on rocks or soil. Some species are responsible for...

01:22Hair Cells

Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.

01:21Green Algae
779
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...

Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.
