As a composite lipid excipient based on alkyl glycosides and fatty acid monoglycerides, OILREE® MY AP-18 (
Coco glucoside or
Glyceryl oleate), with its natural and gentle composition characteristics, the core advantages of adapting to tear-free formulas, and its multifunctional application performance, has become a high-quality choice for adapting to tear-free systems in the research and development of care formulas, and provides a new raw material solution for the innovation and upgrading of gentle care products.
What is a tear-free formula?
Tear-free formula, also known as weakly acidic formula, is a formula system of care products developed to care for delicate skin and eye mucous membranes. It is also a basic requirement for skin care products for infants and children. It is now widely used in adult care products for sensitive skin.The original intention of its research and development stems from the characteristics of infant and child hair development: the eyes and lacrimal glands of infants and young children are not yet fully developed, unable to secrete enough tears to form protection, and there is little blinking, the eyes' ability to protect themselves from external stimuli is extremely weak, and the irritating ingredients in ordinary care products can easily cause damage to them, and the skin barrier of people with sensitive muscles is damaged, and the skin around the eyes, face and other parts is also highly sensitive to irritants. The emergence of tear-free formula is precisely to solve this core pain point.
From the point of view of the formula principle, the core characteristics of the tear-free formula are reflected in three aspects.
First, a low-irritating or even non-irritating cleansing system that does not contain or contains very little soap, abandons traditional strong irritating surfactants, and selects gentle cleansing ingredients to reduce irritation to the skin and eye mucosa from the source.
Second, it fits the pH value of the physiological environment. The formula is mostly weakly acidic, matching the natural pH environment of the human skin and the eye area, and avoiding dry skin, cracked or eye discomfort caused by acid-base imbalance.
Third, the non-ionized molecular structure, the active ingredients in the formula do not exist in ionic form, the molecular volume is large and uncharged, and it cannot penetrate the protective layer of the eyes and skin. At the same time, the molecular surface area is large, which can better protect the skin barrier while achieving the cleansing function.
Why is ap-18 adapted to the tear-free formula?
As a coco-glucoside or glyceryl oleate complex, Ap-18 belongs to the category of lipid excipients. Its core composition and physical and chemical properties are highly compatible with the research and development requirements of tear-free formula. This is also the fundamental reason why it can become a high-quality raw material for tear-free formula.From the point of view of composition, the main ingredients of ap-18 are 28-35% coconut oil-based glucosides and 25-45% glyceroleic acid esters, supplemented by water and citric acid. The core ingredients are low-irritating and highly compatible raw materials, avoiding the introduction of irritating ingredients from the source.
As an important category of alkyl glycosides (APG), Coco glucoside is a nonionic surfactant synthesized from glucose and natural fatty alcohol. It itself has very low eye mucosa and skin irritation, which is also the core advantage of ap-18 adapted to tear-free formula.Alkyl glycoside ingredients have excellent compatibility with the skin. They are not only non-irritating on their own, but also reduce the irritation of other active agents in the formula. This characteristic makes it the core raw material of low-irritating care formula and an indispensable ingredient in children's care products.As a natural fatty acid derivative, glyceryl oleate has both moisturizing and liposuction effects. It can replenish lipids for the skin during the cleansing process, repair the skin barrier, and avoid dryness and tightness after cleansing.
From the point of view of physical and chemical properties, the water-soluble properties of ap-18 make it easy to integrate into the water-based care formula, and it is perfectly compatible with the water-based system of the tear-free formula. It is in the form of a transparent yellow viscous liquid at 25℃, which can provide a good consistency foundation for the formula without adding too much thickener and reducing the complexity of the formula.At the same time, the pH value of ap-18 can be flexibly adjusted by citric acid, which can easily match the weak acidity requirements of the tear-free formula and avoid the risk of irritation caused by acid-base imbalance.In addition, the characteristics of ap-18 without cloud points and electrolyte resistance enable it to maintain stable performance in the formula, and will not cause precipitation, stratification and other problems due to environmental changes, ensuring the use experience and quality stability of tear-free formula products.
More importantly, the mechanism of action of ap-18 is highly compatible with the core requirements of the tear-free formula.As a liposuction, it does not achieve cleansing through strong degreasing, but while gently cleansing, it replenishes lipids for the skin and scalp and protects the natural sebum membrane.
Application scenarios of Ap-18's tear-free formula
1. Core categories of maternal and child care
Baby shampoo and shower gel is the core application scenario of the tear-free formula and the main adaptation product of ap-18.The scalp and skin stratum corneum of infants and young children are thin, and the sebum membrane has not yet been fully developed. Cleaning products must not only be tear-free and non-irritating, but also avoid excessive degreasing.In the formula of baby shampoo and shower gel, ap-18 can not only rely on the gentle cleansing ability of coco glucoside to effectively remove dirt from the skin and scalp, but also through the liposuction effect of glyceryl oleate, leaving a layer of lipid protective film for the skin after cleansing to prevent moisture loss and keep the skin hydrated.At the same time, its thickening properties can create rich and delicate foams for shower gels and foam baths to enhance the use experience, and the foams are easy to rinse and have no residues, avoiding secondary irritation caused by residual ingredients to infant skin.
2. Adult care for sensitive skin
In adult care products for sensitive skin, ap-18 can also show excellent adaptability.A shampoo formula for people with sensitive skin. The gentle properties of ap-18 can reduce irritation to the scalp and avoid itching and redness of the scalp caused by cleansing ingredients. At the same time, its liposuction effect can improve the dryness and desquamation of the scalp of sensitive muscles.In a gentle shower gel, ap-18 can achieve gentle cleansing of the skin of the whole body, even in sensitive areas such as the eye area and neck, there will be no discomfort after contact.In non-irritating cleansing products, it is both water-soluble and gentle, which can easily clean facial oil and dirt, while protecting the facial skin barrier, and is not tight or dry after washing. It is suitable for dry sensitive muscles, oil sensitive muscles and other sensitive muscle types.
3. Special care for children
With the refined development of the children's care market, products such as children's cleansing foams and children's conditioners have also begun to adopt tear-free formulas, and the liposuction properties of ap-18 make it perfectly suitable for such products.In children's cleansing foam, ap-18 can provide gentle cleansing power and rich foam for the formula, which is suitable for children's daily facial cleansing.
The four core advantages of Ap-18 to create a tear-free formula
Advantage one
The core ingredient of ap-18, coco glucoside, is synthesized from natural glucose and fatty alcohol, while glyceryl oleate is derived from natural fatty acids. Both are green and environmentally friendly raw materials with high biodegradable rates and friendly to the environment.Unlike traditional petroleum-based surfactants, ap-18 does not contain toxic by-products such as dioxane, ethylene oxide, and nitrosamines, as well as irritating ingredients such as saponins and sulfates, which guarantees the safety of tear-free formula products from the source.
Advantage two
The research and development of tear-free formula requires minimizing the types of raw materials and reducing the complexity of the formula. ap-18 combines the three core functions of liposuction, thickening, and stabilization to achieve “one material and multiple functions”.As a lipid excipient, it can replenish lipids and protect the barrier for the skin and scalp.As a thickener, its own viscous properties can provide good consistency for care products. There is no need to add too much thickener to reduce the types of raw materials in the formula. At the same time, ap-18 can improve the stability of the formula, avoid precipitation, stratification, unstable foam and other problems during storage and use of the product, and ensure the consistency of the quality of tear-free formula products.
Advantage three
The research and development of tear-free formula requires a variety of raw materials to work synergistically, and ap-18 has excellent compatibility, can be combined with various ionic and nonionic surfactants to produce synergistic effects, and can also be perfectly compatible with common tear-free formula raw materials such as
Hydrogenated castor oil, and will not produce antagonistic reactions.Whether it is an amino acid cleansing system, a gentle non-ionic cleansing system, or a moisturizing repair system, ap-18 can be easily integrated, and can enhance the overall gentleness and use effect of the formula.
Advantage four
Ap-18 has excellent stability, can be stored for a long time in a wide temperature range, acid, alkali, hard water resistance, no gel phenomenon, whether in the production process or in the daily use of consumers, it can maintain stable performance.In the use process, even in hard water environments, ap-18 can maintain good cleanliness and foaming properties, and will not affect the use effect due to water quality problems, and adapt to the needs of consumers in different regions.
Conclusion
From maternal and child care to sensitive skin care, from shampoo and bathing to cleansing and hair care, the emergence of ap-18 has enabled tear-free formula products not only to achieve the core requirements of no tears and no irritation, but also to take into account multiple functions such as cleaning, maintenance, and moisturizing, bringing consumers a better gentle care experience.
