57. REVIEW OF GUIDELINES FOR
HERBAL COSMETICS BY PRIVATE
BODIES LIKE COSMOS WITH
RESPECT TO PRESERVATIVES,
EMOLLIENTS, FOAMING AGENTS,
EMULSIFIERS AND RHEOLOGY
MODIFIERS.
57
58. COSMOS
58
COSMOS stands for "cosmetic organic and
natural standard", which sets certification
requirements
for organic and natural cosmetics products in
the europe.
It was developed by five charters members:
BDIH (germany).
Cosmebio (france).
Ecocert (france).
Icea (italy).
Soil association (great britain).
The standard is recognized globally by
the cosmetic industry.
59. 59
By adhering to specific guidelines, cosmetics
marketers can use COSMOS signatures, which
are registered trademarks, on packaging to
confirm the products meet minimum industry
requirements to be considered organic or
natural.
What does it contain?
The cosmos-standard applies to cosmetic
products that are marketed as organic or
natural. Its guiding principles are to:
Promote the use of products from organic
agriculture, and respect biodiversity.
Use natural resources, and respect the
environment.
60. PRESERVATIVES
60
Cosmetic preservatives allowed by Ecocert and
COSMOSE are considered more skin friendly
than some traditional preservatives.
Preservatives are the chemical substances used to
improve or amplify shelf life of drugs by decreasing
or lowering the oxidation of active and excipients
and by reducing microbial production
According to the latest Ecocert and
COSMOS standards the following preservatives
are allowed in cosmetic products certified as
natural and organic:
61. 61
Phenoxyethanol – This ingredient is not
approved by COSMOS but it is a common
preservative for natural formulation.
It has a light rose odor.
It is effective against some bacteria and fungi.
Also good against pseudomonas.
It has a wide pH range and is effective from pH
3 – 10.
Phenethyl Alcohol – This ingredient is
approved by COSMOS and works similarly to
phenoxyethanol. It has a stronger odor.
Organic acids and their salts – There are a
wide range of organic acids that are effective
as preservatives.
62. 62
These include:
Benzoic acid
Sodium benzoate
Sorbic acid
Potassium sorbate
Dehydroacetic acid
Salicylic acid
These ingredients are mostly approved by the
COSMOS standard and are effective against
fungi and to some extent bacteria.
They only work at lower pH however so if you
use them you need to formulate below pH 5.0
63. 63
Benzyl Alcohol – This material is effective
against a broad spectrum of microbes.
While it can be found in nature most of the
benzyl alcohol used commercially is
synthetically produced.
One drawback is that it is a known allergen.
There are also some compatibility issues
with benzyl alcohol and nonionic surfactants.
Natural preservative boosters:
The following ingredients can help disrupt
growth by interfering with the microbial cell
membranes.
Caprylyl Alcohol
Caprylic Acid
64. 64
Gluconolactone
Glyceryl Caprylate
Ethylhexyglycerin
Other fragrance components have some
preservative boosting activity
Levulinic Acid
p-Anisic Acid
There are also some enzymatic systems
that have been successfully employed in
natural cosmetic formulations.
Glucose Oxidase
Lactoperoxidase
65. 65
Some natural ingredients that have some
antimicrobial functionality.
They are not broad spectrum effective so
should not be used as the sole preservative
system.
Tea tree oil
Rosemary
Cinnamon
Grapes fruit seed extract
Honeysuckle extract
66. EMOLLIENTS
66
Emollient is a refatting agent, i.e. An ingredient
of a cosmetic formulation that provides the
skin with the fat it needs. It reduces
evaporation and thus increases the moisture
content of the skin.
According to COSMOS standard for Natural
& Organic Cosmetics :
Candelilla Cera
Palmitic & Stearic Acid
Isopropyl Myristate
Isopropyl Palmitate
68. EMULSIFIERS
68
Emulsifiers are used as adjuvants for
combining non-miscible fluids into an emulsion.
The molecular structure of the emulsifiers
reduces the surface tension between the
hydrophilic and lipophilic constituents, thus
promoting the formation of finely dispersed
mixtures.
The emulsion stabilizers improve and help to
maintain the stability and shelf-life of
dispersions.
According to COSMOS standard for Natural
& Organic Cosmetics:
Glyceryl Stearate Citrate
71. FOAMING AGENTS
71
Surfactants are surface active agents widely used in
cosmetics products specially in Shampoos,
Dentifrices, etc. These compounds are
characterized by foam production and reduction of
surface or interfacial tension.
According to COSMOS standard for Natural
& Organic Cosmetics:
Coco-Betaine
Cocamidopropyl Betaine
Sodium Cocoamphoacetate
Caprylyl Capryl Glucoside Coco-Glucoside
Sodium Lauryl Sulfate
Decyl glucoside
73. RHEOLOGY MDIFIERS
73
The term Rheology derived from two Greek words
namely rheo (to flow) and logos (science).
Rheology is the science that deals with the
deformation of matter under the influence of
stresses like tensile stress, shearing stress, etc.,
It deals with the fluids flow.
Rheological additives generally focused to
Thickeners.
Their primary roles in flow behavior may include
detergency, emulsification, foam stability or
conditioning.
75. CHALLENGES IN FORMULATING HERBAL
COSMETICS
75
Natural cosmetic and beauty products are
vogue now a days and cosmetic marketers
around the world are looking to launch their
own version that appeals to green-seeking
consumers.
However, making natural cosmetics is fraught
with difficulties stemming from the fact that
beauty products do not exist in nature.
The biggest challenges in making natural
cosmetics include:
Defining what is natural
76. 76
Defining Natural
Before review natural cosmetics, it is
helpful to first discuss what is meant by the
term natural.
For this discussion, use a three-level
classification system of natural cosmetics:
True natural - Ingredients are isolated
from a plant and chemically purified, but
otherwise unchanged.
Acceptable natural - Ingredients
conform to some acceptable natural
standard that allows some chemical
modification.
77. 77
The majority of natural products on the
market would be considered green washed.
Making Functional Products
The biggest challenge to making natural
cosmetics is that consumers have an
expectation of how well products are
supposed to work.
While consumers might say they want green
or natural products, they really want products
that work.
When formulating natural cosmetics, it
becomes difficult because natural or naturally
derived ingredients do not work as well as
78. 78
This is especially true for surfactants, colorants
and preservatives.
Surfactants
Surfactants are the most versatile and important
ingredients in cosmetic formulations.
Unfortunately, there are not many surfactants
that naturally occur, so trying to make natural
formulas with surfactants is a real challenge.
True natural - There are not many natural
surfactants that are adequate for use as
cleansers.
79. 79
The closest are saponins. These are
glycoside compounds that have the ability to
form foam when put in a water solution.
They are found in plants like yucca (Yucca
schidigera), soapwort (Saponaria officinalis),
soapbark (Quillaja saponaria) and soapnut
(Sapindus spp).
The majority of commercial saponins are
derived from soapbark or soapnut via water
and alcohol extraction.
Unfortunately, formulators reported using
saponins for cleansing products have been
disappointed in their performance.
80. 80
Acceptable natural - according to USDA
natural organic standards, there are no natural
surfactants you can use.
Some companies like nourish organic use a
chemical trick where they create a
surfactant in situ by including natural
ingredients that chemically react to make a
soap.
In one formula, the coconut oil will saponify
with the potassium hydroxide.
If you are following the cosmos standard,
there are many surfactants that are
acceptable.

The ones typically used for cleansing
products are lauryl glucoside, decyl
glucoside, caprylyl/decyl glucoside, coco
glucoside and cocamidopropyl betaine.
COSMOS standard even allows for the use
of sodium lauryl sulfate (SLS) since it can be
derived from natural sources.
Green washing natural -
The use of cleansing surfactants like SLS is
probably not a good idea.
Sulfates have a bad reputation, and even
though they are considered natural by the
COSMOS standard.
82. 82
However, some companies simply replace
sulfates with other synthetic anionic surfactants.
These include ingredients like taurates,
sarcosinates, and glutamates.
Colorants
In United States, there is no ingredient more
highly regulated in cosmetics than colorants.
It is illegal to use any ingredient (no matter the
source) to color cosmetics that is not approved
by FDA for such use.
This means if you producing natural cosmetics
the colors you can use will be strictly limited.
83. 83
The majority of approved colorants are
synthetic ingredients.
Even mineral ingredients like iron oxides, zinc
oxide and titanium dioxide are all synthetic.
The only approved versions must be
synthetically produced in the lab.
The naturally occurring minerals are
dangerous.
The synthetic versions have much less
contamination.
There are some colorants don't require FDA
certification and come directly from nature
such as annatto, chlorophyllin, carmine, henna
and caramel.
84. 84
Unfortunately, there is a limited range of colors
ingredients can provide.
The strategy most of natural cosmetic
companies follow to either use the direct-
from-nature colorants or use standard
colorants.
Preserving Products
We use natural ingredients becomes more
challenging because microbes are found in
nature.
Effective preservatives such as Parabens,
formaldehyde donors do not fit with a natural
theme, so we need alternatives such as
Phenoxyethanol, Phenethyl alcohol, organic
85. 85
Phenoxyethanol and Phenethyl alcohol have
a distinct odor that is difficult to cover.
Organic acids only work as preservatives at
lower pH levels, which is not ideal for certain
types of beauty care products.
Benzyl alcohol is a known allergen.
Other natural materials like tea tree oil,
rosemary or cinnamon are not broad
spectrum enough to work as a stand alone
preservative.
